High-quality and high-yield fertilization method for continuous cropping of potatoes in greenhouse

Abstract

The invention discloses a high-quality and high-yield fertilization method for continuous cropping of potatoes in a greenhouse. 40-60 kilograms of a high-concentration balanced humic acid complex organic-inorganic compound fertilizer, 80-100 kilograms of a high-concentration high-potassium humic acid complex organic-inorganic compound fertilizer, 70-80 kilograms of a humic acid trace element organic fertilizer and 30-40 kilograms of an amino acid high-calcium organic fertilizer are applied to the bottom of soil per mu. The high-concentration balanced humic acid complex organic-inorganic compound fertilizer and the high-concentration high-potassium humic acid complex organic-inorganic compound fertilizer are adopted, the humic acid trace element organic fertilizer and the amino acid high-calcium organic fertilizer are applied in combination, and the problem of continuous cropping of the potatoes in the greenhouse is solved.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a high-quality and high-yield fertilization method for repeated planting of potatoes in greenhouses. Background technique [0002] The scientific name of potato is potato, which is the fourth largest food crop in the world, and it is also a food and vegetable crop. Especially when planted in plastic greenhouses, it can be put on the market nearly one month earlier than when it is planted in the open field in early spring. It is very beneficial to the development of the potato industry. . However, potatoes in greenhouses are generally planted with heavy cropping. For potatoes that avoid heavy cropping, the yield will continue to drop from 2000-2500 kg for new crops to about 1500 kg. It is also difficult to increase the output of product wastes such as fermented organic fertilizers. Potatoes are high-yield crops, and the higher the yield, the bigger, more uniform, better...

AI Technical Summary

Problems solved by technology

[0005] Traditional inorganic compound fertilizers have high nutrient content of nitrogen, phosphorus and potassium, and they are released quickly and concentrated after fertilization. Too much application will damage the roots and burn seedlings, and too little application will cause insufficient fertility and low yield; traditional organic fertilizers can be used at low temperatures below 25°C. Under certain conditions, the decomposition and release of nutrients are slower, and the season cannot be played well. Traditional organic fertilizers and inorganic compound fertilizers are used in combination or single application, which cannot effectively solve a series of problems in the cultivation of potatoes in greenhouses.
