Rooting agent for preventing and treating clubroot diseases of cruciferae crops, and preparing method and application of rooting agent

Abstract

The invention provides a rooting agent for preventing and treating clubroot diseases of cruciferae crops. Effective constituents of the rooting agent comprise 0.1-0.5 part of a water-soluble boron compound, 140-250 parts of a water-soluble nitrogen compound and 49-60 parts of organic fertilizer. The rooting agent is applied in the growth period after plants, infected with the clubroot diseases, of the cruciferae crops such as oilseed rape come into twelve true leaves, induction and growth of enough new roots of the plants, infected with the clubroot diseases, of the cruciferae crops such as the oilseed rape can be effectively facilitated, the yield loss of the plants infected with the diseases is lowered to the greatest extent, and economic benefits of growers are guaranteed. The invention further provides a preparing method of the rooting agent, wherein the rooting agent is prepared by mixing raw materials and then conducting granulation, operation is easy and convenient, and cost is low.

Description

technical field [0001] The invention relates to a plant rooting agent, in particular to a rooting agent for preventing and treating clubroot plants of cruciferous crops, a preparation method and application thereof. Background technique [0002] In my country, cruciferous crops such as rapeseed, cabbage, cabbage, mustard greens, green vegetables, and radishes are widely cultivated. Among them, cruciferous vegetables include vegetable crops such as cabbage, cabbage, mustard and radish, which are the most widely planted and most commonly eaten vegetable types in my country. However, cruciferous crops are susceptible to clubroot and are extremely difficult to control. With the increase of varieties and area of ​​cruciferous crops, the acidification of soil, and the warming of the global climate, the occurrence area of ​​cruciferous clubroot in my country has been expanding year by year, and the severity has been aggravated year by year. One of the important diseases of plants....

AI Technical Summary

Problems solved by technology

[0012] At present, there is no effective method to prevent and treat cruciferous clubroot susceptible plants at the 6-leaf stage and above growth stage, to minimize or avoid the death or yield reduction of infected crops, and to ensure the economic interests of growers

In addition, the commonly used agricultural control measures and chemical control measures in the fields mostly use methods such as spreading, root irrigation, and watering, which are prone to burn seedlings due to uneven use of fertilizers and drugs, and can also easily lead to soil compaction and chemical drug pollution. Problems such as excessive residues, reduced stability of farmland ecosystems, and increased planting costs of cruciferous crops have emerged
