Biological weeding reclamation and soil fertility improvement method of abandoned farmland

Abstract

The invention discloses a biological weeding reclamation and soil fertility improvement method of an abandoned farmland. The method comprises the following steps of: (1) building a fenced poultry house; (2) buying young chicken and adult geese, and placing into a fence according to 180 to 200 chicken per Mu; placing the geese into the fence according to a ratio of chicken to geese of (10 to 15) to 6, raising the chicken and the geese together, supplementing feed at nightfall, and gradually reducing the feed amount; (3) when the feed is supplemented, adding intestinal zymocyte into the feed; when the exposed surface of the abandoned land due to the weeding by the poultry is greater than 20 percent, all tender leaves of grasses are eaten by the poultry, the upright grasses are completely stepped into the earth, the plant height is less than 5cm, and the leaves are withered and yellow, covering the surface layer with straws, adding straw decomposition agent, simultaneously spraying urea and glucose aqueous solution until the surface of the straw is wetted; (4) shallowly ploughing the land, then sowing trefoil, and spraying the urea solution on the leaf surface once a week when a plant height is greater than 5 cm; and (5) interplanting corns when the trefoil grows to 10 to 15 cm. By adopting the method, the weeding efficiency is high, environmental conservation is realized, and ecological poultry can be raised.

Description

technical field [0001] The invention relates to a method for controlling weeds and soil fertilization in abandoned farmland, in particular to a method for reclamation of abandoned farmland, controlling weeds and soil fertilization. Background technique [0002] Land is related to the national economy and the people's livelihood and supports thousands of households. There is an extremely acute and prominent contradiction in my country's land, that is, there are more people and less land. However, due to the accelerated pace of urbanization and the continuous adjustment of the industrial structure in recent years, a large number of labor forces have been liberated from the land and transferred to the secondary and tertiary industries. Many rural areas have experienced land idleness and abandonment to varying degrees. Therefore, the reclamation of abandoned rural land is an urgent need for scientific planning, rational utilization, effective protection of land resources and th...

[0004] The artificial weeding method requires a large amount of labor force, low labor efficiency and high labor cost

Although the chemical weeding method saves trouble and labor and has good short-term effects, it is difficult for the herbicide to reach the root of the grass, and it is easy to treat the symptoms but not the root cause. The weeds are easy to come back, and the herbicides have to be used repeatedly, which will inevitably lead to the rise of the cost of weed removal, which is economically unbearable; Herbicides destroy the ecological balance. While controlling weeds in a short period of time with repeated spraying, they also enhance the resistance (resistance) of weeds, make the dominant populations more rampant, and gradually exterminate a variety of beneficial animals and microorganisms, consume soil nutrients, destroy Soil structure and farmland ecological balance; herbicides cause farmland environmental pollution, pollute soil and water, bring hidden dangers to the safety of agricultural products, and do not meet the requirements of sustainable agricultural development

Therefore, chemical weeding methods are not suitable
