Problems solved by technology

[0004] It can be seen from the above data that there are still some disadvantages in straw returning to the field. 1. There are many pests in the straw returning to the field, which affects the harvest: the straw contains a large number of larvae, which are difficult to eliminate during the crushing process. Farmers will continue to plant grain in the second year. Start to dig the soil, turn the worms into the soil again, and slowly grow into adults, which become a hidden danger to the crops and threaten the crop harvest; 2. The degradation cycle is long and affects sowing: after the straw is returned to the field, it will be turned under the soil, It is difficult to completely clean up and then plant crops, but the seeds of the crops will not completely touch the soil. Once there is drought and water shortage, the crops will "die", which will affect the sowing; Able to contact the soil, but this isolates the straw from the air and affects the degradation cycle
3. Affect the germination rate: Since the straw is not completely absorbed and digested by the land, new crops are planted, which will inevitably affect the emergence rate of the crops, and will also lead to a decrease in the fertility of the land
In order to ensure the normal growth of crops, farmers will continue to add fertilizer, and the pests and diseases that have not been treated cleanly, farmers spend money and effort
4. Affect soil microorganisms: If the amount of stalks returned to the field is too large or the soil is unevenly turned, it is easy to cause conflicts between soil microorganisms (that is, microorganisms converted from straws) and crop seedlings for nutrients, and even yellow seedlings, dead seedlings, and reduced production. Phenomenon
[0005] At present, there is no method to solve the above-mentioned problems of straw returning to the field

Embodiment 1

[0034] A method for returning straws to the field comprises crushing plant straws and returning them to farmland, and turning the crushed plant straws into the ground to a depth of 30 cm.

Embodiment 2

[0036] A method of returning straw to the field, crushing the plant straw and returning it to the farmland, turning the crushed plant straw into the ground to a depth of 30cm, and watering the farmland with a water consumption of 55m 2 / mu.

Embodiment 3

[0038] A method of returning straw to the field, crushing the plant straw and returning it to the farmland, turning the crushed plant straw and acid-producing bacteria into the ground at a depth of 30 cm, and watering the farmland. Water consumption is 55m 2 / mu. The acid producing bacterium is a composition of Clostridium butyricum and Clostridium coeriformis according to the mass ratio of 1:1; both Clostridium butyricum and Clostridium coercii are purchased from the China Industrial Microorganism Culture Collection Management Center, and the preservation numbers are respectively CICC 20763 and CICC 20021.

[0039] Acidogenic bacteria are carried out according to the following steps: the original bacteria of acidogenic bacteria are inoculated to the Fe containing 5mmol / L 2+ Acid-producing bacteria were obtained through dark fermentation culture in the culture medium.

[0040] The culture medium is 2 g of tryptone, 1 g of beef extract, 0.6 g of yeast extract, 0.4 g of corn ...

Abstract

The invention relates to a straw returning method, which comprises the following steps: crushing plant straws, and returning the crushed plant straws to the farmland. The method is characterized in that the crushed plant straws are turned into the underground. According to the invention, the burst of the grassland borer can be effectively prevented, the degradation of the straws is accelerated, the emergence rate of crops is increased, and the crop yield is increased.

Description

technical field [0001] The invention relates to a method for returning straw to the field. Background technique [0002] my country is a large agricultural country. The traditional planting mode is to directly burn the straw left in the field after harvesting wheat and rice, and then carry out the next round of farming. Burning can kill some insect eggs and pathogenic bacteria. Of course, burning produces A large amount of smoke pollutes the environment; and in recent years, the country has paid more attention to environmental protection, prohibiting straw burning, and requiring straw to be returned to the field, because farming is not profitable now, and most of the farmers in rural areas are post-60s, and most of them are mechanically harvested and sowing, and straw returning to the field are directly smashing the straw in the field without other management, and then planting the next round of crops; resulting in some insect eggs and pathogenic bacteria cannot be killed, esp...
