Plant protection method for protecting rice field by propineb and herbicides

Abstract

The invention discloses a plant protection method for protecting a rice field by propineb and herbicides. 80-100g of propineb and a conventional dose of herbicides are mixed and applied to the rice field by one-time operation per mu; the plant protection method is applicable to fields with artificially transplanted big seedlings or machine-transplanted seedling fields and scattering-planted seedling fields. The traditional production mode of repeated weeding and fertilizing operation is broken through; 'weeding, damage control, seedling raising and disease prevention' effects can be achieved in a whole through single operation; reviving and tillering are about 10 days earlier; all seedlings can grow strong and mature at the same stage after transplanting, and high yield is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, more specifically, it relates to a method for plant protection of paddy fields with zinc and herbicide mixed application. Background technique [0002] Since the 1980s, weeding, seedling raising and tillering fertilizer application in paddy fields have continued the traditional practice of "two steps", that is, the first step: weeding, and the second step: fertilization. Although this "two-step" method of weeding and fertilization has been used until now, its limitations are inevitable and increasingly apparent. [0003] One is prone to drug injury.

AI Technical Summary

Problems solved by technology

[0003] First, it is easy to cause drug injury

The technical requirements for the use of herbicides in paddy fields are very high. A little carelessness in the use process can easily cause herbicide damage. Not only the weeding effect cannot be guaranteed, but also the innocent seedlings will be injured, causing yellow seedlings, twisting, sitting and stiffness. Seedlings, dead seedlings, or even whole field plants withered and died

[0004] Second, the elimination of drug harm requires secondary investment

[0005] The third is hidden dangers of safety chain

Since the source of seedlings cannot be guaranteed in time, there will be no suitable-age seedlings available for replanting, and the emergence period of replanting will be greatly delayed, resulting in inconsistent growth periods and failure to mature at the same time, directly affecting the growth of rice throughout the season

[0006] The fourth is to delay the raising of seedlings

[0007] Fifth, it is labor-intensive, time-consuming and costly

It not only wastes the golden time of the reproductive period and the time of multiple operations, but also increases the capital cost of multiple investments
