Key Technical Points for Foliar Fertilization of Cotton to Prevent Premature Senescence
In the late growth stage of cotton, root activity gradually declines and the ability to absorb water and nutrients weakens accordingly. Adopting the method of spraying fertilizer solution promotes the absorption and utilization of nutrients by cotton, extends the functional period of leaves, improves root activity, and increases boll weight. As for the concentration of the fertilizer solution, urea is best at 1%, adding 0.5 kg of urea to 50 kg of water; potassium dihydrogen phosphate and superphosphate are best at 1%-1.5%. Superphosphate should first be soaked for 24 hours; after the impurities settle, slowly pour out the clear liquid, dilute with water, and then spray. At the same time, Tianfengsu or Shuofeng 481 may be appropriately added, which can

Detailed Explanation of Fine Processing Methods and Technical Points for Gastrodia elata
Gastrodia elata must be processed as soon as it is dug up and harvested, because if stored for too long, it easily loses its sap, reducing the drying ratio. Spring-harvested Gastrodia elata especially cannot be stored. Spring temperatures are high, and if it is not processed in time, it will also become moldy and rot. During processing, first wash the dug-up Gastrodia elata clean of soil with clean water, then wipe off the moisture with a cloth, and then put it in a pot to stir-fry together with fine sand. According to the size of the pot (No. 1 or No. 2 pot), put fine sand in each pot for stir-frying. According to the size of the pot (No. 1 or No. 2 pot), put 4-7.5 kg of fine sand in each pot and 1.5-2.5 kg of Gastrodia elata. It should be processed according to

Asexual Propagation Methods and Key Technical Points for Gastrodia elata
It should be divided into the following steps: (1) For seed tubers, select fresh, intact white tubers or small tubers that are disease-free, frostbite-free, and rot-free. The planting period is from October each year to May of the following year. In April of the following year, when the ground temperature rises and Gastrodia elata begins to grow (10-15°C), Armillaria mellea (which begins to grow at 6-8°C) can already supply nutrients to Gastrodia elata. (2) Fixed fungus bed cultivation method. This is carried out in the original fungus wood cultivation pit. First, scrape open the covering of the pit with the fixed fungus wood, take out the upper layer of fungus wood, and then scrape open the filler on the fixed fungus wood. After the bottom layer of fixed fungus wood is exposed, do not move the fungus wood

Propagation Methods and Key Technical Points for Gastrodia elata
I. Asexual Propagation 1. Cultivation period. Generally, winter planting is carried out in November, and spring planting in March-April, with winter planting being preferable. 2. Selection of seed tubers. White tubers and rice tubers are preferred, with each weighing 5 g-10 g being optimal. Select those with no disease spots, no wounds, no frost damage, no rot, a spindle-shaped body, and obvious bud eyes as seed tubers. Some also use arrow tubers as seed tubers, but the terminal buds must be removed. 3. Amount of seed tubers used. This should be determined by the size of the seed tubers and the number of fungal logs per pit. Generally, for each pit using 9-10 fungal logs,

Key Technical Points for Improving the Survival Rate and Yield of Sexual Propagation of Gastrodia elata
Tuyan is one of the main Gastrodia elata production areas in Hubei, with wild Gastrodia elata widely distributed, and both the climate and soil within its boundaries are suitable for sexual propagation of Gastrodia elata. Combining local environmental conditions and based on practical experience, the author has summarized the key techniques for sexual propagation of Gastrodia elata suited to the local natural environment. 1. The quality and quantity of fungal inoculum are the foundation for ensuring the germination and growth of Gastrodia elata seeds. (1) The germination rate of Gastrodia elata seeds depends on the quality and quantity of the seed germination fungus. Practice has shown that sowing Gastrodia elata with No. 8104 seed germination fungus mixed in gives a high germination rate and fast germination speed.

Brine Processing Method and Technical Key Points for Oyster Mushrooms
Oyster mushroom, also known as abalone mushroom, is an edible fungus that can be eaten fresh or processed into canned goods for export, and is extremely rich in nutrients. Brine processing of oyster mushrooms is simple to operate, easy to transport, and offers relatively high economic returns. Grade standards for oyster mushrooms (divided into 2 grades in total). Grade 1 mushrooms: grayish-white in color, 3-12 cm in diameter, without stems; the few with stems must not exceed 1 cm. The tissue is tender, the shape is complete, the edge of the cap has no severe shrinkage or cracks, no mud, sand or other impurities, no pests or diseases, no shrinkage or deterioration, no off-odor, and must not be soaked in water. Grade 2

Key Technical Points and Detailed Methods for Oyster Mushroom Cultivation
Plastic bag cultivation saves labor, is easy to manage, makes full use of mushroom house space, reduces pests and diseases, and makes cultivation success easier. It is suitable not only for indoor cultivation, but also for cultivation in plastic greenhouses, air-raid shelters and other places, and the bags can also be placed in paddy fields, corn fields and vegetable plots for intercropping with rice, corn and vegetables. This is a new cultivation method that has been widely adopted in recent years. 1. Specifications for plastic bags: choose plastic tubes (open at both ends) 0.03-0.04 cm thick, 24-30 cm wide and 40-50 cm long.

Key Technical Points for Imitation-Wild High-Quality Cultivation of Oyster Mushrooms in Winter and Early Spring
Oyster mushrooms produced using imitation-wild cultivation techniques not only taste as fresh and delicious as wild ones, but also truly achieve ecological, high-quality, and high-yield production. Even in the cold winter and low-temperature early spring seasons, high-quality oyster mushrooms that are thick, fleshy, fresh, and tender can be produced in a relatively enclosed shade shed by making full use of ground temperature. This method increases yield by more than 60% compared with conventional cultivation methods, and by more than 40% compared with cultivation methods such as mushroom walls, with a biological conversion rate of more than 220%. 1. Mycelium culture. Use high-pressure or atmospheric-pressure sterilization, inoculate conventionally, and culture until physiologically mature mycelium is obtained.

Key Technical Points for Environmental Control in Greenhouse Lily Cultivation
In lily cultivation, besides having high-quality bulbs, strict control of the growing environment according to the requirements of different varieties throughout the entire growth process is also needed to produce lily products with good plant form and high quality. If conditions are not well controlled, it will not only affect the plant form of the lilies, but in severe cases also affect plant growth, and may even prevent normal flowering. The following briefly introduces environmental control during lily cultivation based on the requirements of lily planting. 1. Greenhouse A good growing environment can ensure the normal growth of lilies.

Detailed Explanation of Key Technical Points for Field Cultivation and Management of Lilies
When carrying out field cultivation, the following aspects of work should be done well. (1) Select good varieties according to the cultivation purpose and local climate conditions, soil, and other factors. (2) Choose a suitable plot: select sloping land with high and dry terrain (with a gentle slope) or flat land, with loose, deep soil and medium organic matter content, and the plot should have good drainage capacity. For plots prone to drought, it is better to have a certain irrigation capacity. In addition, lilies are unsuitable for continuous cropping; a plot where lilies have been grown can only be planted with lilies again after 3-5 years, and the previous crop is best
