Detailed Explanation of Key Points of Shiitake Mushroom Sterilization and Inoculation Techniques
Shiitake mushroom culture media mostly use the method of normal-pressure high-temperature sterilization to achieve the purpose of killing harmful organisms. (1) Bag substrate sterilization: Put the bags filled with substrate into the sterilization stove and sterilize at normal pressure. Before the substrate bags enter the stove, first add enough water to the steamer. When loading the bags into the stove, they must not be arranged in a "pin" shape; they should be stacked overlapping from top to bottom, with gaps left between rows so that airflow moves freely up and down. After the bags enter the chamber, immediately burn with a strong fire so that the temperature rises rapidly to 100°C within 6 hours and continues for 20-24 hours, without the fire dropping midway. Achieve "attack the beginning, protect the end,

A Detailed Explanation of Processing Techniques and Utilization Methods for Dog By-products
The processed dog skin has good cold-resistant and moisture-proof performance and an attractive fur color, and can be made into vests, mattresses, and so on, and is very effective for the waist soreness and cold legs of elderly people and rheumatism patients. 1. Processing: During processing, first clean the meat, greasy matter, feces, dirt, and blood off the dog skin, lay it flat on a wooden board, and rub it with coarse sandcloth or a brick until the coarse hair roots are slightly visible. Then use 500 g of alum, add 5000 ml of water, boil, pour into a basin, and after it cools, fully immerse the dog skin, take it out after about 24 hours, place it hair-side down on

Detailed Explanation of Key Points in the Disease Immunization Program for Silkie Chickens
Bacterial diseases in Silkie chickens can be prevented and treated with antibacterial drugs, while viral diseases can only be prevented through immunization. Therefore, formulating a reasonable immunization program is particularly important. Only with a scientific and reasonable immunization program can the health of the flock be ensured, thereby achieving maximum economic benefits. The formulation of an immunization program should, first, be based on the epidemic situation of diseases in the local area and the rearing environment, that is, no prevention is needed for infectious diseases that have never occurred in the local area; diseases that have not occurred before in the local area but have just begun to occur and are seriously harmful must be prevented; and those that occur frequently and are seriously harmful

Key Techniques for Foliar Fertilization of Cotton at Different Growth Stages
1. Fertilization at the seedling stage: Foliar fertilization at the seedling stage can promote early development of cotton seedlings, help weak seedlings become strong ones, control plant height and prevent excessive vegetative growth. Generally, a mixture of 1% urea and 1%-2% superphosphate soaking filtrate is sprayed at 50-75 kg. 2. Fertilization at the bud stage: For cotton fields with normal growth, 300-500 times diluted potassium dihydrogen phosphate plus an appropriate amount of zinc fertilizer can be sprayed; the growth peak of cotton plants appears before flowering, and excessively rapid vegetative growth will cause early row closure and increase the shedding of buds and bolls in the middle and lower parts. Such cotton fields need

Detailed Explanation of Fertilization and Watering Methods and Technical Points for Schisandra chinensis
(1) Watering and Fertilization. Schisandra chinensis (five-flavor berry) prefers fertilizer and needs sufficient water and nutrients during the growing season. After planting and establishment, water frequently to keep the soil moist. Irrigate once before the ground freezes to aid overwintering. During the bud differentiation, flowering and fruiting stages, in addition to sufficient water, large amounts of nutrients are also needed. Apply chemical fertilizer twice a year: the first application during the leaf expansion stage, with quick-acting nitrogen and potassium fertilizer. The second application after the plants flower (mid-growth period, early July), with quick-acting phosphorus and potassium fertilizer. As the plant grows larger, the fertilizer amount increases year by year: ammonium nitrate 25-100 g/plant, superphosphate

How to fertilize Schisandra chinensis? A detailed explanation of practical fertilization techniques
Building a successful Schisandra chinensis orchard makes scientific fertilization the key. Schisandra chinensis is a perennial plant, and after planting it must grow continuously for more than 10 years within a limited nutrient range. As the cultivation years increase, the nutrients in the soil gradually decrease, the underground creeping stems are widely distributed, the growth is vigorous, and nutrient consumption is high. Therefore, rational fertilization is very important for the growth of Schisandra chinensis. The fertilization method and amount should pay attention to the following aspects. In the year Schisandra chinensis is transplanted, the root system is not well developed and the branches are thin and weak. In order to promote the seedlings and strive to bear fruit in the second year, urea can be applied in late May

What are the field cultivation and fertilization measures for Schisandra chinensis?
Schisandra chinensis is a medicinal plant with relatively high economic value. Currently, the Schisandra chinensis sold on the market is mainly wild, with very little cultivated artificially. At the same time, the market demand for Schisandra chinensis is very large, and the price is relatively stable. Collecting wild Schisandra chinensis alone is far from enough to meet market demand, so artificial cultivation of Schisandra chinensis is being developed in many regions. Cultivating Schisandra chinensis is different from ordinary field crops, and there are relatively strict requirements for fertilizer use. After transplanting and survival, the soil for Schisandra chinensis should be kept moist, and timely irrigation should be carried out during drought. Every year

Methods and Techniques for Rational Utilization of the Three Wheat Feeds
Wheat bran, wheat chaff and wheat straw are collectively known as the three wheat feeds, and they are important feeds in the main wheat-producing areas. Rational utilization of the three wheat feeds can promote the development of the livestock industry. If used improperly, they will not only fail to produce the desired effect, but will also cause livestock and poultry to contract certain diseases, resulting in economic losses. Wheat bran belongs to the high-phosphorus, low-calcium feed category, and the ratio of phosphorus to calcium it contains is 4:1, which is the opposite of the physiological calcium-to-phosphorus ratio required by livestock and poultry, which is 1.5:1 to 2:1. Feeding too much wheat bran can cause calcium deficiency disease due to an imbalanced calcium-to-phosphorus ratio, such as rickets in young animals, osteomalacia in adult animals

Emergency supplementary fertilization for cotton to promote plant recovery and regrowth
Yang Xiushen, a researcher at the Industrial Crops Research Institute of the Provincial Academy of Agricultural Sciences, said that since July, our province has been repeatedly hit by torrential rains, and the flooding has caused widespread inundation of farmland, inflicting severe damage on cotton. Draining water and reducing waterlogging, and emergency supplementary fertilization to promote recovery are the critical priorities of the current disaster relief and remediation effort. At the same time, weeds must be removed promptly, the soil loosened, and earth hilled up around the roots, and replanting and supplemental planting should be carried out according to the conditions of each field. Emergency removal of standing water in the fields must seize the time and adopt all necessary and possible means to quickly drain the standing water, reduce the impact of waterlogging on cotton growth and development, and lower the mortality rate of cotton seedlings. For low-lying areas, especially secondary
