Problems solved by technology

Due to the large amount of corn stalks returned to the field, especially the difficulty of returning corn stalk leaves to the field, the main performance is that the corn leaves are large in size, fluffy, and weak in water permeability. The phenomenon of withering immediately after emergence, the rate of seedling preservation in spring is low

Embodiment

[0015] In the windy sandy soil area of ​​the Northeast Plain, two treatments were set up to carry out control experiments on the farmland with the same conditions. The traditional straw returning was used in the control treatment farmland, and the other treatment combined with the integrated method of returning corn straw to the field for production:

[0016] A method of combining agriculture and animal husbandry with integrated corn stalks returning to the field, the specific steps are as follows:

[0017] In step 1, the harvester cuts off the corn stalks scattered on the surface of the corn field while harvesting the corn; the length of the corn stalks cut by the harvester is ≤ 10 cm.

[0018] Step 2: Grazing cattle in the non-growing season, using the grazing mode to use cattle to eat corn stalks scattered on the ground; the residual straw after cattle eating and excrement of cattle are scattered on the surface of the corn field, forming a mixed surface of corn stalks and ca...

Abstract

The invention discloses a farming and grazing combined integrated corn straw field returning method. The method specifically includes the steps that corn straw is cut off to be scattered on the earthsurface of a corn field while corn is harvested by a harvester; cattle grazing is carried out in a non-growing season, and cattle eat the corn straw scattered on the earth surface in a grazing mode; the straw left after the cattle eat the straw and excreted faeces of the cattle are spread on the surface of the corn field, and mixed earth surface covering of the corn straw and the excreted faeces of the cattle is formed; the mixed earth surface covering of the corn straw and the excreted faeces of the cattle is mixed into surface soil during field preparation in spring of the last ten days of April next year, and straw field returning is achieved. Compared with a conventional field returning method, the emergence rate is increased by 12%, the field returning quantity of organic materials isincreased by 22%, and economic income benefits of agricultural production are increased by 8.4%.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to an integrated method for returning corn stalks to the field with the combination of agriculture and animal husbandry. Background technique [0002] At present, a large number of by-products of corn stalks are produced in the process of agricultural production. The technology of straw returning to the field has always been relatively backward, which has a great impact on agricultural production, and it is difficult to emerge, which affects grain production. The traditional method of returning corn stalks to the field generally adopts the method of crushing the corn stalks while harvesting, and then deep plowing or rotary tillage with a high-powered tractor. Due to the large amount of corn stalks returned to the field, especially the difficulty of returning corn stalk leaves to the field, the main performance is that the corn leaves are large in size, fluffy, and we...
