Special multi-effect nutrient for rape base application

Abstract

The invention belongs to a special multi-effect nutrient for rape base application, which comprises the following components in percentage by weight: 0.8 to 1.2 percent of trichoderma, 2.0 to 28.0 percent of N, 6.0 to 12.0 percent of P2O5, 4.0 to 9.0 percent of K2O, 2.0 to 5.0 percent of S, 1.0 to 1.5 percent of zinc sulfate, 1.0 to 2.0 percent of boric acid, 0.04 to 0.08 percent of 10 percent of S-abscisic acid, and the balance of filler. The nutrient can meet the reasonable nutrition requirement of rape, enhance the resistance of the rape against adverse situations of drought damage, cold damage, frost, water logging damage and the like, promote balanced absorption of nutrients, promote early growth and quick development, enhance the disease resistance, ensure normal growth of the rape, improve the yield of the rape and improve the quality.

Description

technical field [0001] The invention belongs to an agricultural composition, in particular to fertilizers and pesticides in the agricultural composition, in particular to a special multi-effect nutrient for rape base application. Background technique [0002] Rapeseed is an important oil crop in Sichuan. It is a crop planted in autumn and harvested in summer. The growth period goes through three seasons of autumn, winter and spring. The climate changes greatly and the growth period is long. It is often affected by autumn rain, frost, cold wave, winter dryness and spring drought. In addition, blind fertilization causes nutrient imbalance, resulting in poor growth and development, delayed seedling emergence, weak and thin seedlings, flowers but not fruit, and unstable and low yields. Sclerotinia is one of the most common and destructive diseases of rapeseed, with high incidence and great damage, often causing great losses to rapeseed production. [0003] The existing method i...

Problems solved by technology

[0002] Rapeseed is an important oil crop in Sichuan. It is a crop planted in autumn and harvested in summer. The growth period goes through three seasons: autumn, winter and spring. The climate changes greatly and the growth period is long. It is often affected by autumn rain, frost, cold wave, winter dryness and spring drought. In addition, blind fertilization causes nutrient imbalance, resulting in poor growth and development, delayed seedling emergence, weak and thin seedlings, flowers but not fruit, and unstable and low yields

Sclerotinia is one of the most common and destructive diseases of rapeseed, with a high incidence and great damage, often causing great losses to rapeseed production

[0003] The existing method is that the farmers apply nitrogen fertilizers many times to promote seedlings, spray boron fertilizers during the flowering period to solve the problem of flowers but not fruit, and repeatedly apply chemical pesticides to prevent and control Sclerotinia, spray boron fertilizers, and apply chemical pesticides for multiple fertilization, which is labor-intensive. Time-consuming, troublesome operation, often leads to nutrient imbalance, poor resistance, either vigorous growth and lodging, or premature aging due to defertilization, chemical pesticides cause pesticide residues to pollute the environment

[0004] At present, there are no good preventive solutions for the above-mentioned situations.
