Description

Narrow row spacing intertillage fertilization weeder

Technical Field

The utility model relates to agricultural intertillage machinery, in particular to a narrow-row-spacing intertillage fertilizing and weeding machine.

Background

Intertillage is one of the important links of fine cultivation in China agriculture. During intertillage, earth surface soil can be loosened, the soil is turned over, weeds are removed, the ground temperature is improved, fertilizers are decomposed and absorbed, water evaporation can be reduced, the effects of storing water and preserving soil moisture are achieved, and the soil under the earth surface is kept to have certain humidity; in addition, the intertillage can also eliminate soil hardening, improve soil properties, increase soil air permeability, create good growth conditions for crops, and promote high and stable yield of the crops. The process of intertillage operations is often accompanied by fertilizing and weeding operations.

Weeds, as an important part of the agroecological environment, directly affect the yield of agricultural production. Weeds compete for soil nutrients and water with grain crops directly, especially in some areas where water resources are in short supply, roots of the weeds are deeper than roots of crops, so that the weeds absorb more water than the crops, and the growth trend of the grain crops is directly influenced. According to the FAO organization survey report of the United nations, billions of tons of grains are directly or indirectly lost due to the influence of diseases, insects, disasters, grasses and other hazards in the world every year. Wherein the loss due to weeds can be about 10%. It follows that the problem of weeds is a non-negligible part of the process of increasing the yield of food crops, and therefore necessary measures need to be taken against weeds in the field to reduce the extent of losses.

The field weeding mode in the prior art mainly comprises manual weeding and chemical weeding, the manual weeding occupies a large amount of manpower and material resources, and the labor intensity is high and the efficiency is low. Among a plurality of weeding modes, chemical weeding gradually replaces traditional artificial weeding with the characteristics of high efficiency and labor saving, thereby causing the situation that the chemical weeding is the main weeding mode at present. However, chemical weeding can lead the herbicide to permeate into the soil and remain in the soil for a long time, and long-term use of the herbicide can lead to repeated accumulation of harmful elements in the soil, soil pollution, reduction or absolute harvest of grain yield, increase of field weed resistance, influence on human health and the like. The intertillage fertilizing and weeding machine adopting mechanical weeding is often applied to crops with wider planting row spacing such as corn, soybean and potato, and for crops with narrow row spacing such as wheat and oat planted by a machine, the intertillage fertilizing and weeding machine has the phenomena of poor adaptability, difficult ground operation of row spacing width, high seedling injury rate and the like during intertillage operation.
