Clever Fertilization in the Late Stage of Cotton: Disease Prevention and Yield Increase at the Same Time
In the late growth stage of cotton, the root system's ability to absorb nutrients declines noticeably, but if fertilizers such as nitrogen, phosphorus, potassium, zinc and boron are sprayed on the cotton leaves, they can prevent premature senescence, promote early maturity, prevent disease, prevent boll shedding and help set large bolls, with a significant yield-increasing effect. 1. Apply nitrogen fertilizer to prevent premature senescence: each time use 75-100 kg of 1% urea solution per mu, spray once every 5-7 days, for 2-3 consecutive sprays, which can enhance leaf photosynthesis and prevent premature senescence and increase yield. 2. Apply phosphorus fertilizer to promote early maturity: in the late stage of cotton, spraying phosphorus fertilizer on the leaves,

Spraying cotton with seven liquids can increase yield by 100 jin
According to many years of trials by our local agricultural science institute and cotton-grower science households, spraying the following nutrient liquids mixed with pesticide during pest control at different growth stages of cotton can effectively increase yield by 20%-30%. The methods are described below: 1. Chicken manure liquid: take 3 kg of fermented dry chicken manure, 2. add 7.5 kg of water, 3. soak for 30 hours, 4. then boil for 2-5, 3 hours, 6. filter out the residue, 7. then ferment again, 8. until white mold appears on the liquid surface, 9. filter out the white mold, 10. add 50 kg of water, 11. spray evenly on 1 mu of cotton field. 12. Rabbit manure liquid:

How can cotton be given base fertilizer skillfully to increase yield?
For base fertilizer in cotton fields, first, apply more organic fertilizers of various kinds, or bio-organic compound fertilizers; second, achieve formula fertilization and balanced fertilization, applying nitrogen, phosphorus and potassium in a ratio of 3:1:3; third, for insect-resistant cotton, apply more potassium fertilizer, with no less than 15 kg per mu as base fertilizer, plus 0.5-0.7 kg of zinc fertilizer and 0.4 kg of Chilibor; fourth, apply fertilizer in an appropriate amount, and do not blindly pursue quantity; applying 25-30 kg per mu of high-content ternary compound fertilizer is sufficient; fifth, change broadcast application to furrow application or hole application, and the cotton seedling roots should maintain

Why oyster mushroom transplanting gives such good yield increases
Practice has shown that thinning and transplanting densely clustered mushroom buds gives good yield increases. The transplanting method is as follows. 1. Transplant at the right time: transplant when the mushroom buds have just appeared. 2. Planting material: there are no strict requirements; they can be planted on either spawn material that has not yet fruited or material that has already been harvested. Spawn material that has not yet fruited helps the mycelium wounds from transplanting heal and the fruiting bodies develop well. 3. Transplanting method and management: transplanting should be done by digging holes in the spawn brick or spawn bed. Place the small clump of mushroom buds that has been picked into the hole that has been dug, and press firmly around it so that the mushroom buds and the spawn material on the surface of the spawn brick or bed

Small tricks to increase oyster mushroom yields: learn these methods for higher production
1. Water with mushroom root water. Put the mushroom roots trimmed off after adding into a pot, add water just to cover them, boil for 20 minutes, take the filtrate, add 7-10 times clean water, and pour it into the water trough on the mushroom wall after harvesting the first flush. This liquid has complete nutrition and is absorbed and converted quickly, generally increasing yield by 10%. 2. Spray hormones. During the young bud stage, spray 0.5‰ ethephon solution once each during the oyster mushroom bud stage, young mushroom stage and cap expansion, 50 ml per square meter each time, which can promote budding and early maturity and increase yield by 20%. 3. Spray trace elements

How to increase the yield of lilies? Master these four methods
Lily, also known as white lily and lily garlic, has effects such as moistening the lungs and stopping cough, clearing the heart, and calming the mind. It is an economic crop suitable for both medicinal and vegetable use, with relatively high planting benefits. Under conventional cultivation and management, farmers can adopt the following four methods to achieve the goal of increasing yield and efficiency. 1. Chemical regulation method. When lily seedlings grow to 18-20 cm tall, carry out chemical regulation: per mu use the plant growth regulator paclobutrazol 20-50 grams, or mepiquat chloride 10-15 grams, or daminozide (B9) 5-10 grams, or mepiquat chloride 5-10 grams, choose any one, add water 50-

Scraping the mushroom bed surface of oyster mushrooms can increase mushroom weight
After two harvests of oyster mushrooms, the bed surface often becomes severely dry and compacted, with poor air and water permeability, and the mycelium becomes senescent and weak, which delays the fruiting time, reduces mushroom yield, and may even result in no mushrooms at all. Scraping the bed surface can effectively solve this problem and produce a very good yield increase. The method for scraping the bed surface is: for a severely compacted bed surface with an overly thick mycelial skin, scrape off a thin layer of the aged mycelial skin over the entire surface. For a slightly compacted bed surface with a relatively thick mycelial skin, use a wire to scratch many small crisscrossing grooves until the mycelium is exposed. For ridge-bed cultivation,

Adding table salt to oyster mushroom substrate can increase yields
In oyster mushroom cultivation, using carbendazim to control contamination by foreign fungi is effective, but pesticide residues remain in the mushrooms, which is harmful to human health, and the cost is relatively high. According to experiments: when cultivating oyster mushrooms on raw substrate, adding 1.5 kg of table salt per 100 kg of dry substrate (dissolved in advance in a measured amount of water) and mixing thoroughly can prevent infection by foreign fungi and also bring mushrooms out 5-7 days earlier. At the same time, because table salt is rich in sodium, calcium, magnesium and other metal ions needed for oyster mushroom growth, if a 10% salt solution is sprayed in the early stage of fruiting body differentiation and after each flush is harvested, the mushrooms can be free of pesticide residues and their quality

Spraying oyster mushrooms with cooled boiled water can significantly increase yield
Spraying cooled boiled water at different stages of oyster mushroom fruiting can increase the biological conversion rate by 33%, and oyster mushrooms sprayed with cooled boiled water flush faster, fruit evenly, and have thick, plump caps. After the oyster mushroom mycelium has fully colonized, remove the plastic film and spray the mushroom bed and the surrounding walls once with cooled boiled water so that the relative air humidity reaches 80-85%; when coral-like primordia appear in large numbers, as the fruiting bodies gradually grow, spray cooled boiled water 3-5 times a day to raise the air humidity to 95%. When spraying, use a fine mist; do not irrigate heavily, so that standing water does not cause mushroom death

Seven methods of applying nutrient solutions to increase oyster mushroom yields
1. Sucrose and calcium carbonate phosphate mixed solution: sucrose 1%, calcium carbonate 1%, potassium dihydrogen phosphate 0.1%. Use when the mycelium has covered the mushroom bed and before fruiting bodies appear. 2. Urea and citric acid mixed solution: urea 0.5%, citric acid 0.1%, adjust pH to 7 with sodium hydroxide. Use after the first flush of mushrooms is harvested. Using it after the second flush is not effective and instead hinders oyster mushroom growth. 3. Sugar, urea and citric acid mixed solution: sucrose, citric acid and urea 1% each, adjust pH to 7. Same
