Embodiment 1

[0021] A kind of paddy rice, rapeseed crop rotation method, carry out according to the following steps:

[0022] A. Use deep plowing to plow and level the soil. The plowing depth is 20-30cm. Add water until the water surface is 2-3cm higher than the soil surface. Soak the field for 6 days;

[0023] B. Drain the accumulated water in the field, sprinkle phosphogypsum and microbial fertilizers on the field, plow and level it again, plant rapeseed and add fertilizer regularly;

[0024] C. After harvesting, smash the straw directly in the field; use deep plowing to plow and level the soil, and sprinkle microorganisms in the field before plowing. The plowing depth is 20-30cm, add water, and the water surface is higher than the soil surface. 10-15cm, insert rice seedlings, put earthworms;

[0025] D, spray photosynthetic bacteria on the leaves every 13 days in the early stage of rice growth;

[0026] E. Microbial fertilizers and earthworms need to be added every time the water is p...

Embodiment 2

[0032] A kind of paddy rice, rapeseed crop rotation method, carry out according to the following steps:

[0033] A. Use deep plowing to plow and level the soil. The plowing depth is 20-30cm. Add water until the water surface is 2-3cm higher than the soil surface. Soak the field for 5 days;

[0034] B. Drain the accumulated water in the field, sprinkle phosphogypsum and microbial fertilizers on the field, plow and level it again, plant rapeseed and add fertilizer regularly;

[0035] C. After harvesting, smash the straw directly in the field; use deep plowing to plow and level the soil, and sprinkle microorganisms in the field before plowing. The plowing depth is 20-30cm, add water, and the water surface is higher than the soil surface. 10-15cm, insert rice seedlings, put earthworms;

[0036] D, spray photosynthetic bacteria on the leaves every 12-15 days in the early stage of rice growth;

[0037] E. Microbial fertilizers and earthworms need to be added every time the water i...

Embodiment 3

[0043] A kind of paddy rice, rapeseed crop rotation method, carry out according to the following steps:

Abstract

The invention provides a crop rotation method for rice and rape. Microbial fertilizer and phosphorus gypsum are matched, and meanwhile earthworms are put, so that soils are improved and fertilizers for rape and rice growth are provided. According to the crop rotation method, on one hand, yields are improved, on the other hand, adsorption of a saline-alkali land to different kinds of saline matterscan be accelerated, improvement speed of the saline-alkali land can be accelerated, yields of rape and rice are increased year by year, and improvement of the saline-alkali land can be basically completed after 2-3 years.

Description

technical field [0001] The invention relates to the technical field of improving saline-alkali land, in particular to a rice and rape rotation method. Background technique [0002] Saline-alkali land is the general term for salt land and alkaline land. Saline soil mainly refers to saline soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, and the soil is alkaline. Saline-alkali land has low organic matter content, low soil fertility, poor physical and chemical properties, and many anions and cations harmful to crops, making it difficult for crops to promote seedlings. The area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. The formation of alkaline land and alkaline soil in my country is mostly related to the accumulation of carbonate in the soil, so the ...
