Problems solved by technology

An important method of fertilizing saline-alkaline rice fields is to return rice straw to the field. However, due to the high salt content in saline-alkali land, it is not conducive to the decomposition of rice straw. Inhibited, the effect of increasing the fertility of saline-alkali land by returning straw to the field is not ideal

Embodiment Construction

[0026] use figure 1 with figure 2 A method for improving the fertility of a saline-alkaline paddy field according to an embodiment of the present invention is described as follows.

[0027] Such as figure 1 with figure 2 Shown, a kind of saline-alkali paddy field fertility improvement method of the present invention, the method comprises the steps:

[0028] S1: Transport the harvested rice straw to the spray room and spray it with a mixed solution mixed with rotting additives in clean water. The straw after spraying will be more humid, which will help improve the ability of the land to conserve water for a period of time, and provide straw Provide sufficient conditions for fermentation;

[0029] S2: Put the rice straw sprayed in S1 into the hopper of the straw returning machine, and install a plow in front of the straw returning machine, use the straw returning machine to deeply plow the saline-alkali land, dig out the deep soil, and form a fermentation pit;

[0030] S...

Abstract

The invention belongs to the technical field of straw returning to the field, and specifically relates to a method for improving the fertility of saline-alkaline paddy fields. Spraying; put the sprayed rice straw into the hopper of the straw returning machine, and install a plow in front of the straw returning machine; the straw returning machine is driven by a diesel engine to move in the saline-alkali paddy field, and the straw is returned to the field The machine crushes the rice straw and sprinkles it on the saline-alkaline paddy field; a storage box for the biological agent solution is installed in the straw returning machine, and when the straw returning machine crushes the rice straw, the biological agent solution falls on the surface of the crushed straw, so that the biological bacteria The fertilizer is in full contact with the straw; the nitrogen fertilizer solution storage tank is hung behind the straw returning machine; the oxygen tank is installed at the bottom of the straw returning machine, and the oxygen nozzle is located behind the plow. The invention is beneficial to rapidly converting straw into soil nutrients and improving soil fertility.

Description

technical field [0001] The invention belongs to the technical field of straw returning to the field, in particular to a method for improving the fertility of a saline-alkaline paddy field. Background technique [0002] Straw is an important part of rural waste at present. The burning of straw causes a substantial increase in greenhouse gas emissions every year, and a large amount of active ingredients such as cellulose in straw are wasted. With the development of social economy and changes in national policies, agricultural machinery has been vigorously developed. Especially at present, the country promotes the development of large areas of cultivated land through the promotion of farms and cooperative systems, promotes the use of large agricultural machinery, improves agricultural production efficiency, and reduces Resource consumption, improve the recycling rate of straw, and protect the environment. Returning the straw to the field by crushing can effectively increase th...
