Straw returning method and straw returning comprehensive land preparation machine

Abstract

The invention discloses a straw returning method and a straw returning comprehensive land preparation machine. The straw returning method comprises the following steps of: performing crushing, cleaning stubbles, performing rotary tillage, performing ridging and spraying corrosive bacteria liquid. Compared with land parcels in which straws are returned to fields partially or are not returned to thefields, land parcels in which straws are totally returned into fields have the characteristics that the soil moisture conservation effect is superior to that of the contrast land parcels, and the drought resistance is improved; the ground temperature is increased, and can be higher than the ground temperature of the contrast land parcels by 1-4 DEG C, and crops in the land parcels can be early matured for 7 to 10 days; and the fertility is increased, and the returned straw fertilizer takes effect in the same year, can be maintained for 2 to 3 years, and is fully decomposed into fertilizer insoil. The straw returning comprehensive land preparation machine has series products and high adaptability, and can be matched with large or small tractors. The straw returning comprehensive land preparation machine has series products for lands with 2 to 7 ridges, and is used for tractors with different horsepower.

Description

technical field [0001] The invention relates to the field of farming technology and equipment, in particular to a straw returning method and a straw returning comprehensive soil preparation machine. Background technique [0002] Since ancient times, spring plowing and autumn harvesting, corn stalks have been discarded after harvesting. In the past, the rural areas were used for heating, cooking, and feeding livestock. A large number of them are discarded. In order not to miss the farming season, collective burning causes air pollution, and the amount of effective utilization is small, which cannot completely solve the problem of remaining straw. The farming season is very tight, and if the straw is not disposed of in time, it will affect the agricultural production of the next season. Contents of the invention [0003] The purpose of the present invention is to provide a straw returning method and a comprehensive soil preparation machine for straw returning, which can retu...
