Detailed Explanation of Key Points for Pollution-Free Management Techniques of Tea Plants
Tea garden soil should be ploughed frequently to facilitate microbial activity, accelerate soil maturation, promote the release of mineral elements, and facilitate root absorption. Depending on the soil structure, carry out shallow ploughing several times a year, with a depth of 5-10 cm; medium ploughing 2-3 times, with a depth of 10-15 cm; deep ploughing once a year or every other year, with a depth of 25-30 cm. Shallow ploughing and medium ploughing can be carried out in combination with weeding and topdressing in each tea season, while deep ploughing is carried out in combination with garden cleaning or applying organic fertilizer. Tea gardens should be given more organic fertilizer to improve soil physical and chemical properties and the capacity for sustained nutrient supply; appropriately stock

Key Technical Points for Pollution-Free Tea Plant Cultivation and Management
I. Cultivation and Management of Tea Gardens in the Young Stage 1. Deep plowing to improve soil. Water is an important component of the tea plant organism. Deep plowing to improve the soil can store water and retain moisture, ensuring good root growth and development of tea plants. During deep plowing, do not mix up the topsoil and subsoil; place them separately in the inner side and outer trench. When backfilling, put the topsoil at the bottom of the trench and spread the subsoil on top. The depth of deep plowing must be more than 50 cm. 2. Transplanting. The transplanting time should be determined according to local conditions and varieties, generally from late February to mid-March in early spring, or from mid-October to early November in late autumn and early winter. It is advisable to choose cloudy days

Production Management Methods and Technical Key Points for the Growing Period of Oyster Mushrooms
After the large-scale formation during the mulberry stage and the brief coral stage, the mushroom bodies gradually enlarge and enter the growing period. At this time, management should be strengthened so that the mushroom bodies differentiate and mature within 5-7 days. Specific management measures: ① Ventilation. To prevent deformed or rotten mushrooms caused by excessive stale air in the room, ventilate 3-4 times daily to supply fresh air. ② Moisture retention. Adequate air humidity is an important condition for the enlargement of the mushroom bodies, so mist water should be sprayed in the room 4-5 times daily. However, avoid water accumulating on the caps, so as to prevent curling. The relative air humidity should be maintained at 9

What are the storage management methods for lily bulbs?
The storage site should follow the principles of "dry, ventilated, shaded, and light-blocked." Lily bulbs used for storage must be "fully mature, low in moisture content, free of disease and pests, and without wounds." Seed bulbs that have been disinfected with chemicals can be used for storage to reduce rot. The storage method mainly adopts the sand-soil stratification method. Before storage, the lily bulbs should be spread out indoors briefly, but not for too long to avoid discoloration. Then choose a cool room and fumigate it once with 0.3% formaldehyde and potassium permanganate. Then spread a layer of clean garden soil or river sand 5-7 cm thick on the ground, place the lily bulbs upside down on it in neat rows, and cover with another layer of soil or sand about 3-4 cm thick. Repeat this process until the height does not exceed about 1.5 m, then seal the surroundings tightly with soil or sand. They can be stored until the following spring. During storage, check once every 20-30 days. Do not turn them over too much. If any spoilage is found, remove it promptly.

How to raise rabbits well in winter? Good feeding management is key
Keeping warm: In a low-temperature environment, rabbits lose a lot of heat and grow slowly, which affects their development and reproduction. Therefore, the rabbit hutch should be well maintained, windows sealed tightly, and cracks plugged to keep the hutch warm. Supplementary greens: Feeding green, juicy feed in winter can enhance rabbits' appetite and promote their growth, development and reproduction. Commonly used green, juicy feeds include cabbage, radish, bean sprouts, etc., but the daily feeding amount should not be too large, otherwise it easily causes diarrhea in rabbits. Add night grass: Rabbits have nocturnal habits. In winter, the days are short and the nights are long, so night grass should be added. At the same time, increase

How to raise velvet deer well? An analysis of the key points of feeding and management techniques
Deer belong to the class Mammalia, order Artiodactyla, family Cervidae, genus Cervus, and among them, deer whose velvet antlers have medicinal value are all called velvet deer. The velvet deer domesticated in China are mainly sika deer, red deer, white-lipped deer and black deer, etc. Deer antler velvet is a precious traditional Chinese medicinal material, with effects such as promoting spermatogenesis and replenishing marrow, enriching blood, strengthening yang, and strengthening tendons and bones. Others such as deer fetus, deer blood, deer sinew, deer penis, deer bone, deer meat, deer heart, deer liver and deer skin are all first-class raw materials for medicine and industry. Velvet deer have high economic value, and wild resources are scarce, so @#@253@#@ is a promising good industry. 1. The living habits of deer Because the history of deer domestication is relatively short, they still retain the wild habits of their ancestors. Their hearing, vision and smell are well developed, and they are timid and easily startled, fleeing quickly at the slightest disturbance. Under normal circumstances, male deer are more aggressive than female deer. Under natural conditions, they mostly live in groups, ranging from a dozen to several dozen, and we can use their strong social nature for domestication and grazing. Deer are herbivores and have the physiological function of rumination, feeding on various plants year-round. Green grass, crop straw and the branches of trees and shrubs are all good feed for deer. Under artificial feeding conditions, soybean cake, corn, wheat bran, etc. can be used as supplementary concentrated feed. 2. Deer shed construction The deer farm should be chosen in a place with high and dry terrain, flat and spacious, good drainage, sufficient sunlight, abundant forage grass, and shelter from the wind in winter. Because deer are wild by nature, the pens should be sturdy. The pen area should be 2-3 sq m per deer, the exercise yard 8-10 sq m per deer, and the enclosure wall height 2-2.2 m. The pens should be paved with brick, stone or cement flooring, and equipped with feeding troughs and water troughs. 3. Feeding and management The purpose of raising velvet deer is to obtain deer antler velvet. Therefore, raising male deer well is very important (male deer produce velvet, female deer do not). Feeding male deer can be divided into two stages: the pre-antler-growing period (February to April) and the antler-growing period (May to August), and the mating period (September to November) and the post-mating recovery period (December to January). After February, as the weather turns warmer and the daylight becomes longer, in order to meet the physiological needs of male deer for antler growth, concentrated feed should be gradually increased. A mixed concentrated feed of 1-1.25 kg can be fed, then increased by 70-80 g per day, reaching 2.3-2.4 kg by early May. Among this, protein-rich legume feed should account for more than 50%-60%. Mineral feeds such as salt and shell powder need to be fed at 10-20 g per day, and if conditions permit, some additives such as livestock growth hormones can also be fed. In July, after the first crop of velvet is sawed off, non-breeding male deer should have their concentrated feed reduced by 50%-80%, to avoid fierce head-butting during the mating period. During the mating period, male deer become excited and aggressive due to sexual impulses, and their appetite decreases, so attention must be paid to supervision to minimize injuries and deaths. The feed should be as varied as possible, with more green feed and root feed. The mixed feed should be 0.5-0.75 kg per day. After the mating period, the nutrition of male deer declines, and coupled with colder weather, this is a season when they are prone to death, so roughage should be sufficient, and the mixed concentrated feed should preferably be 0.75-1 kg per day. 4. Reproduction of velvet deer Female deer reach sexual maturity at over 2.5 years of age, and male deer at 2.5-3 years, but mating at 4-5 years is preferable. The estrous cycle of female deer is 17-21 days, the duration of estrus is 18-36 hours, and the gestation period is 224-231 days. The peak estrus season for female deer is September to November. In the early and middle stages of estrus, they show restlessness and excitement, wagging their tails, and the external genitalia swell, become congested and discharge transparent mucus. Mating 12 hours after the onset of estrus makes conception more likely. Male deer with high velvet yield, robust constitution and good hereditary performance should be selected as breeding deer. In terms of mating methods, the one-male-to-multiple-female mating method is currently commonly used, that is, 1 male deer mates with 20-30 female deer, and the conception rate can reach over 90%. May to June is the fawning period for female deer, with 1 fawn per litter, and few twins. The lactation period is 2 months. Male deer produce initial antler velvet at 1 year of age, produce standard deer antler velvet at 2 years of age, and 4-8 years is the peak period of velvet production, with a productive lifespan of up to 12-14 years.

Yingbuluo Nanguo Pear Builds Its Brand Through Scientific Management
1. Fruit tree pruning: Through winter pruning and spring pruning, the fruiting branches are spread out and an umbrella-shaped canopy is formed to achieve ventilation and light penetration. Pay special attention to summer pruning (mid-summer pruning), removing all water sprouts, back branches and new shoots from mature fruit trees, reducing waste of tree nutrients, maintaining the canopy in a moderate state, and ensuring that all nutrients produced by the leaves are effectively used for fruit growth and tree development. 2. Applying farmyard manure: Farmyard manure has a complete range of nutrients and is the most ideal fertilizer for improving fruit quality. Bao Dianhong's orchard applies farmyard manure once every two years, with 200-250 kg of fully decomposed farmyard manure per tree, plus some chemical fertilizer each year. He believes that doing so can both keep the tree vigorous and control excessive tree growth that causes canopy shading, ensuring fruit coloration and improving fruit quality.

Detailed Explanation of New Zealand Spinach Cultivation Techniques and Management Points
(1) Seed preparation: If New Zealand spinach seeds are plentiful, dense sowing or dense planting may be considered, followed by thinning and harvesting, which can increase early-stage yield. New Zealand spinach can be direct-sown or raised as seedlings and transplanted. If New Zealand spinach seeds are insufficient, it is best to raise seedlings and transplant. Direct sowing requires 4-5 jin of seeds. For raising seedlings, plug trays or nutrition pots should be used to reduce root damage, requiring 1.5 kg of seeds. Raising seedlings can save seeds and also allow earlier sowing. Although New Zealand spinach is slow to recover after transplanting, its survival rate is very high. (2) Land preparation, fertilization, and bed making: Because New Zealand spinach has a long growing period, sufficient base fertilizer should be applied
