Method of preventing gramineous weeds in southeast orpines field

Abstract

The invention discloses a method of preventing gramineous weeds in a southeast orpines field. In 60 days before transplanting southeast orpines, fine soil preparation is necessary, and the soil needs to rake carefully by a rake, so that earthnuts and root systems of the perennial gramineous weeds can be removed. In 35 days before planting southeast oprines, glyphosate is sprayed, wherein the glyphosate is made of 10% glyphosate solution 700 grams mixing with water 30 kilograms per mu, and is sprayed on stems leaves of weeds in a directional mode; the glyphosate is fertilized again on the stems leaves of the weeds every 5 days, the glyphosate can effectively remove the annual and perennial gramineous weeds, and the southeast orpines are transplanted after 30 days of secondary spraying. After transplanting southeast oprines, the exuberant period of gramineae weeds growth is from April to September. High-efficient haloxyfop-methyl is sprayed regularly, and the dosage is 60grams-100grams / mu mixing with 15 kilograms of water to prevent the annual and perennial gramineous weeds. The method can effectively prevent most common gramineous weeds, and achieve the purpose of safety, high efficiency, saving time and effort, under the condition of guaranteeing the high security of the southeast oprines.

Description

technical field [0001] The invention belongs to the technical field of gramineous weed control, and in particular relates to a method for controlling gramineous weeds in fields of sedum sedum. Background technique [0002] Grass weeds are the main weeds in paddy fields and dry land, and can be divided into two types: annual and perennial. Larger seeds can germinate at a depth of more than 5cm in the soil, and soil surface treatment herbicides are difficult to control. Generally, manual weeding is used as the main method, such as wild millet, paspalum, etc.; It is only 1-2cm, and the soil surface treatment herbicide has a good control effect, such as barnyard grass and foxtail. [0003] Herbicides can be divided into three categories according to the type of weed control: one is non-selective herbicides, such as paraquat and glyphosate; the other is herbicides for controlling broad-leaved weeds, such as tribenuron-methyl and flusulfame Ether, fluroxyfen, pyrazosulfuron-meth...

AI Technical Summary

Problems solved by technology

[0012] The invention provides a method for preventing and controlling grass weeds in the field of Sedum sedum, aiming to solve the problem that there is no safe herbicide application for Sedum sedum at present. Mainly weeding, including manual weeding and weeding with simple agricultural tools. This method consumes a lot of labor and low work efficiency. It cannot prevent and control grass weeds in a large area in time. At the same time, weeds grow fast. Once weeds break out, the growth of S. high-impact issues
