Method for non-tillage covering cultivation of corn by using crofton weed

Abstract

The invention discloses a method for non-tillage covering cultivation of corn by using crofton weed, and belongs to the technical field of agricultural production. The method for non-tillage covering cultivation of the corn by using the crofton weed mainly comprises the following steps: sowing; applying a base fertilizer; controlling weed; covering with the crofton weed; performing final seedling; applying an additional fertilizer, wherein whole stalks and whole fields are uniformly covered along corn rows by using 22,500 kg of stems and leaves of the non-flowering crofton weed every hectare in the covering step of the crofton weed. The whole process of sowing, base fertilizer application, soil covering, weed controlling and crofton weed covering is finished in one step; the used crofton weed covering has the effects of water retention, temperature increase, leaf area increase and improvement of corn yield; the method has the advantage that the crofton weed is convenient to take and can be utilized on the spot; the contradiction between covering of crop straws and fighting with livestock for coarse fodders is overcome; a new approach is provided for application of the crofton weed in agriculture; sustainable development of the agriculture at arid areas and semi-arid areas is favorably promoted.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a method for covering and planting corn by using Eupatorium adenophorum no-tillage. Background technique [0002] Eupatorium adenophorum is one of the major ecological disaster species facing sustainable development in my country. It is native to Central America and was introduced into southern Yunnan from the China-Myanmar border in the 1940s. It is now widely distributed in many areas of Yunnan, Sichuan, Guizhou, and Guangxi and is moving northward at a relatively fast speed. As a vicious weed, Eupatorium adenophorum has small seeds, strong stress resistance, and can reproduce sexually and asexually, posing a serious threat to biodiversity in tropical and subtropical regions. [0003] In order to slow down the expansion and spread of Eupatorium adenophorum, people have adopted various methods such as chemical agents, biological natural enemies, mach...

Problems solved by technology

[0003] In order to slow down the expansion and spread of Eupatorium adenophorum, people have adopted various methods such as chemical agents, biological natural enemies, machinery, manual removal, and fire, but the results are not great.

In terms of comprehensive utilization, a large number of scientific and technological workers have conducted systematic research on Eupatorium adenophorum in the fields of energy, feed, fiberboard manufacturing, dyes, pesticides, edible fungus substrates, etc., and have achieved gratifying results, but there are cumbersome procedures. , high cost and other issues
