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 and 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 and 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] S3:...

Abstract

The invention belongs to the technical field of straw returning to fields and particularly relates to a fertility improvement method for a saline and alkaline rice field. The method includes the following steps that harvested rice straw is conveyed to a spraying chamber, and a mixed solution of clean water and a decomposition assistant agent is sprayed out; the rice straw on which the mixed solution is sprayed is put into a feeding hopper of a straw returning machine, and a plow is installed in front of the straw returning machine; a diesel is used for driving the straw returning machine to move in the saline and alkaline rice field, and the straw returning machine smashes the rice straw and then sprinkles the smashed rice straw into the saline and alkaline rice field; a biological fungicide solution storage box is arranged in the straw returning machine, biological fungicide solutions fall on the surfaces of the smashed straw when the rice straw is smashed by the straw returning machine, and therefore biological fungicides are fully in contact with the straw; a nitrogenous fertilizer solution storage tank is suspended behind the straw returning machine; an oxygen tank is arrangedat the bottom of the straw returning machine, and an oxygen sprayer is positioned behind the plow. Fast conversion of the straw into soil nutrients is facilitated, and the soil fertility is improved.

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...
