Six Steps for Autumn and Winter Management of Tea Plants Explained
After a year of picking, the tea plant body suffers great damage. If tending work can be done promptly in autumn and winter, it is crucial for accelerating the recovery of the plant body, building up the tree vigor, and achieving high quality and high yield of tea leaves the following year. Therefore, tea farmers should do a good job in six aspects. First is autumn plowing. After the tea plants have been harvested for spring, summer, and autumn tea, they have fully absorbed nutrients from the soil, and the soil has become relatively compacted. If fertilizer is applied at this time, it is not conducive to absorption by the tea plants. Therefore, after the tea garden is closed and tea picking stops, a shallow plowing and loosening of the soil should be carried out,

Key Points and Methods of Tea Plant Canopy Management
1. Tea plant pruning. Tea plant pruning is an important measure in canopy management. Pruning includes formative pruning during the young stage, light pruning and deep pruning of mature tea gardens, and heavy pruning and collar pruning of aging tea gardens. (1) Formative pruning of tea plants during the young stage: Carrying out 3 to 4 formative prunings during the young stage of tea plants can suppress the apical dominance of the main stem of young tea plants, promote axillary bud germination, increase the number of main framework branches, and rapidly form a robust plucking surface with a certain height and width. ① The first formative pruning is carried out after transplanting the cutting seedlings. When the transplanted seedlings reach a height of 25 cm

Nursery Management Techniques for Vegetative Cutting Propagation of Tea Plants
(1) Watering On sunny days, within 20 days after cuttings are inserted, water once in the morning and once in the evening each day to keep the soil moist; from day 20 to 60, water once a day, and pay attention to drainage on rainy days. (2) Fertilizing Fertilizing can begin 60 days after cuttings are inserted, once every 7-10 days, then changed to once every 15 days after 2 months. In the third month after cuttings are inserted, apply 1.5 kg of urea per mu each time; from the fifth month onward, apply 2-2.5 kg of urea each time, and each application per mu must be diluted with 12 dan of water; the fertilizer solution should be mixed evenly to avoid damaging roots and leaves. (3) Removing shade material Tea

Key Techniques for Tea Plant Cultivation and Planting Management Methods
By making use of the characteristics and requirements of tea plant growth and development, selecting superior varieties and suitable land, and carrying out scientific planting and management, these are the technical measures used to obtain high-yield, high-quality commercial beverage tea. Under suitable climate and soil conditions, the technical scope of cultivation mainly covers planting, post-planting management and harvesting. For variety selection, it is advisable to choose tea types suited to the local climate, with high yield per unit area, excellent quality and strong resistance. Propagation can be done by raising seeds in a nursery and then transplanting, or by direct seeding of seeds in the tea garden. Vegetative cutting propagation is mostly used.

Detailed Explanation of Tea Tree Cultivation Techniques and Planting Management Methods
Temperature is a fundamental condition for the life activities of tea trees. It affects the geographical distribution of tea trees and also constrains their growth rate. The influence of temperature on tea trees is mainly manifested in two aspects: air temperature and soil temperature. Air temperature mainly affects the growth of aboveground parts, while soil temperature mainly affects root growth. However, air temperature and soil temperature are interrelated. As far as air temperature is concerned, tea trees can adapt widely from tropical to temperate zones. But for growth, there are three cardinal temperatures, namely the starting temperature for tea tree growth, the optimum temperature, and the low

Detailed Explanation of Four Key Points for Winter Cultivation and Management of Oyster Mushrooms
1) Light should be strong rather than weak. Light is not only an important way to raise the shed temperature in winter, but also an important means to increase yield and improve mushroom quality. Light intensity and duration should be determined according to the insulation performance of the mushroom shed and weather conditions. If the insulation performance of the mushroom shed is good and the nighttime temperature can be maintained above 5°C, then the straw mats on the shed roof can be uncovered early and covered late, extending the daytime light duration as much as possible; otherwise, the daytime light duration in the mushroom shed should be correspondingly shortened. As for weather conditions, when the temperature is below 5°C, on sunny and cloudy days, under the condition of ensuring a shed temperature of 5°C

Key Technical Points for Temperature Management During the Spawn-Running Stage of Oyster Mushrooms
When oyster mushroom mycelium grows thick and vigorous, the spawn-running success rate is high; especially in the sterilized-substrate cultivation process, the mycelium has a lower chance of being infected by contaminant microorganisms than other varieties. However, in the raw-material cultivation process, its temperature requirements during the mycelial growth stage are very strict. Therefore, correctly mastering the suitable spawn-running temperature is the key to ensuring the success of raw-material cultivation of oyster mushrooms. Oyster mushroom mycelium grows vigorously at 20°C-30°C and has strong resistance to contaminant microorganisms; even if occasional contamination occurs, the oyster mushroom mycelium can penetrate and consume it, and the spawn runs quickly, with the mycelium

Management Methods and Technical Key Points for Oyster Mushrooms After Casing Soil
1. Heat preservation and moisture retention: After the oyster mushroom substrate logs are covered with soil, keep the shed temperature at 10°C-15°C, and keep the bed surface moist for about 15 days, until granular mushroom buds appear on the bed surface. After 3-4 days, when the caps grow to 1 cm in diameter, ventilate appropriately for 1 hour at noon. After the mushroom clusters grow larger, ventilate for 1 hour each morning and evening until harvest. Do not water during the growth period of the oyster mushroom fruiting bodies, so as not to drown the young mushrooms or splash soil onto the gills, which would affect the quality and edible value of the oyster mushrooms. 2. Harvesting: Harvest when the oyster mushroom caps curl inward slightly or are flat. When harvesting, support the lower left side of the mycelium with your left hand,

Winter Management After lilies are planted in September-October, the daughter bulbs overwinter in the soil and sprout before Qingming the following year. (1) Loosen the soil and preserve moisture while removing weeds. (2) Fertilizing and earthing up Around January, take advantage of sunny days for fertilizing and cultivation, spreading about 1000 kg of pig and sheep ash manure per mu over the bed surface.

What are the field management measures for lily cultivation?
1. Intertillage and weeding: In the second year after planting, carry out intertillage and weeding 3 times. The first time is after full sprouting in spring, the second time is before flowering in May, and the third time is after flowering in July. The first intertillage should be shallow, and the second and third should be deep. After the rows close, no more intertillage is done, and large weeds are pulled out by hand. 2. Topdressing: Generally topdress 3 times. The first time is around January, applying 2000 kg of decomposed stable manure, 50 kg of cake fertilizer, and 100 kg of plant ash per mu; the second time is when the seedlings are about 10 cm tall, applying 1500 kg of decomposed human and livestock manure
