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: take 1 kg of rabbit manure, 13. crush and add 5 kg of water, 14. boil for 20 minutes then ferment for 4-15, 5 days, 16. filter out the residue, 17. add 40-18, 50 kg of water, 19. spray on 1 mu of cotton field. 20. Silkworm manure liquid: take 1 kg of dry silkworm manure, 21. add 7.5 kg of water, 22. after soaking for 24 hours, 23. add water and boil for 2-24, 3 hours, 25. filter and take the liquid, 26. add 50 kg of water, 27. spray evenly on the leaf surface of 1 mu of cotton field. 28. Urea liquid: the timely spraying concentrations in cotton fields are respectively: three-leaf stage 0.3%; five-leaf stage 0.4%; squaring stage 0.5%; flowering and boll stage 0.5%; boll-opening stage 1-1.2%; autumn boll stage 1%. To improve the effect, 29. at the three-leaf stage each mu (the same below 30.) can be added with 100 g of ferrous sulfate; at the five-leaf stage 1 kg of calcium superphosphate can be added, 31. but it needs to be soaked in 5 kg of water; at the squaring stage 150 g of borax can be added; at the boll-opening stage 150 g of potassium dihydrogen phosphate and 150 g of ferrous carbonate can be added. Spray evenly on both sides of the leaves. 32. White sugar liquid: when cotton plants are squaring, 33. after pruning branches, removing excess shoots and wiping off auxiliary buds, 34. promptly spray a white sugar liquid at a concentration of 1%, 35. to supplement nutrients, 36. promote the wounds to recover as soon as possible 37., 38. and grow robustly; at the full flowering stage spray a 1.5% white sugar liquid, 39. to reduce boll shedding, 40. and help flowering and boll setting. 41. Honey liquid: at the flowering and boll stage spray a honey liquid at a concentration of 1.2%; at the full flowering stage spray a 1.5% honey liquid. The minerals, amino acids, enzymes and other organic elements in honey can quickly supplement the nutrition of cotton plants, 42. help flowering and fruit setting, 43. reduce bud shedding, 44. and enhance disease resistance, disaster resistance and resistance to premature aging. 45. Vinegar liquid: at the three-leaf stage spray 0.3%; at the five-leaf stage spray 0.5%; at the squaring stage 1%; at the flowering and boll stage 1.5%. Applying vinegar (grain vinegar or fruit vinegar are both acceptable) liquid at different 46. 47. concentrations can enhance the photosynthetic effect of cotton plants, 48. make leaves thick, 49. make growth robust, 50. and enhance disease resistance, disaster resistance and resistance to premature aging.
