Problems solved by technology

However, in rice-growing areas, the effective temperature of the soil that is conducive to the decomposition of straw does not last long, and the direct return to the field has a poor effect. A large number of straws have not completely rotted, and compete with plants for nutrients during the growth of plants, which in turn leads to reduced yields. However, the cost of indirect returning to the field is high and the universal performance is poor. For example, in the north, there are few suitable strains and high technical requirements, which is not conducive to the popularization of rice straw returning to the field.

Embodiment 1

[0031] This embodiment provides a fertilization method for returning rice straw to the field in full amount in cold regions, comprising the following steps:

[0032] After harvesting rice in autumn, collect straw and broken rice straw scattered in the field, wherein, the ratio of rice straw per hectare is 1:1 to collect straw (7500kg / hm 2 ), and then return the full amount to the field. Specifically, the collected straw and shredded straw are collected in the field, crushed, and then compressed and granulated to obtain straw granular fertilizer.

[0033] Then, when plowing in autumn, the above-mentioned stalk granular fertilizer and organic fertilizer are buried in the plow layer, and then chemical fertilizers are applied during rotary tillage in the second spring. The applied organic fertilizer is 10t / hm 2 , and applied as a base fertilizer at one time. Fertilizers applied include nitrogen fertilizer 160kg / hm 2 , Phosphate fertilizer 64kg / hm 2 , potash fertilizer 100kg / h...

Embodiment 2

[0036] This embodiment provides a fertilization method for returning rice straw to the field in full amount in cold regions, comprising the following steps:

[0037] After harvesting rice in autumn, collect straw and broken rice straw scattered in the field. Among them, the ratio of rice to straw per hectare is 0.9:1 to collect straw, and then return 90% of the produced straw to the field. Specifically, the collected straw and shredded straw are collected in the field, and then 100% of the collected total amount is pulverized and then compressed and granulated to obtain straw granular fertilizer.

[0038]Then, when plowing in autumn, the above-mentioned straw granule fertilizer is sprinkled on the ground, and then the stalk granules on the ground are buried in the soil during rotary tillage in the second spring, and chemical fertilizers and organic fertilizers are applied at the same time. The applied organic fertilizer is 11t / hm 2 , and applied as a base fertilizer at one ti...

Embodiment 3

[0041] This embodiment provides a fertilization method for returning rice straw to the field in full amount in cold regions, comprising the following steps:

[0042] After harvesting rice in autumn, collect straw and broken rice straw scattered in the field. Among them, the ratio of rice to straw per hectare is 1.05:1 to collect straw, and then return 100% of the generated straw to the field. Specifically, the collected straw and shredded straw are collected in the field, crushed, and then compressed and granulated to obtain straw granular fertilizer.

[0043] Then, when plowing in autumn, bury the above-mentioned straw granular fertilizer into the plow layer, and then apply chemical fertilizers and organic fertilizers at the same time when rotary tillage and land preparation in the second spring. The applied organic fertilizer is 8t / hm 2 , and applied as a base fertilizer at one time. Fertilizers applied include nitrogen fertilizer 175kg / hm 2 , Phosphate fertilizer 70kg / hm...

Abstract

The invention relates to the field of agricultural planting, in particular to a fertilization method of returning full amount of straw to the field in cold regions and a rice planting method. The fertilization method of returning the full amount of straw to the field in the cold regions includes the steps of completely granulating the straw to obtain straw granule fertilizer after an autumn harvest, and then jointly applying the straw granular fertilizer, organic fertilizer and chemical fertilizer into the soil. The fertilization method of returning the full amount of straw to the field in thecold regions has the advantages of effectively improving the rot degree of the straw, preventing the rot of the straw from affecting plant growth during the process of plant growth to thus ensure theincrease of output, and being easy to operate and implement and capable of being widely promoted.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a fertilization method for returning full amount of rice straw to the field in a cold region and a method for planting rice. Background technique [0002] my country is a large agricultural country, and the amount of straw left after the rice harvest is also very large every year. For the convenience of land preparation, farmers mostly use incineration to dispose of straw, which produces a lot of thick smoke and becomes a new source of non-point source pollution in rural areas. Straw incineration is not only the bottleneck of rural environmental protection, but even the chief culprit of urban environment. In 2015, the National Development and Reform Commission, the Ministry of Finance, the Ministry of Agriculture and Rural Affairs, and the Ministry of Environmental Protection requested to expand straw utilization channels through industrialized development, implement standar...
