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,

Example Embodiment

[0030] Example 1

[0031] The present embodiment provides a fertilization method for returning full amount of straw in cold regions, comprising the following steps:

[0032] After the rice harvesting is completed in autumn, the straw and the broken straw scattered in the field are collected, wherein the straw is collected at a ratio of 1:1 per hectare of rice to straw (7500kg / hm 2 ), and then returned to the fields in full. Specifically, the collected straw and broken straw are collected in the field, pulverized, and then compressed and granulated to obtain the straw granular fertilizer.

[0033] Then, during autumn ploughing, the above-mentioned straw granular fertilizer and organic fertilizer were buried in the plough layer, and then chemical fertilizer was applied during rotary tillage in the second spring. The applied organic fertilizer is 10t / hm 2 , and as a base fertilizer once applied. Fertilizers applied include nitrogen fertilizer 160kg / hm 2 , Phosphate fertilize...

Example Embodiment

[0035] Example 2

[0036] The present embodiment provides a fertilization method for returning full amount of straw in cold regions, comprising the following steps:

[0037] After the rice is harvested in autumn, the straw and the broken straw scattered in the field are collected. The straw is collected at a ratio of 0.9:1 per hectare of rice to straw, and then 90% of the generated straw is returned to the field. Specifically, the collected straw and broken straw are collected in the field, and then 100% of the collected total amount is pulverized and then compressed and granulated to obtain the straw granular fertilizer.

[0038]Then, during autumn ploughing, the above-mentioned straw pellet fertilizer was spread on the ground, and then the ground straw pellets were buried in the soil during rotary tillage in the second spring, and chemical fertilizers and organic fertilizers were applied at the same time. The applied organic fertilizer is 11t / hm 2 , and as a base fertilize...

Example Embodiment

[0040] Example 3

[0041] The present embodiment provides a fertilization method for returning full amount of straw in cold regions, comprising the following steps:

[0042] After the rice is harvested in autumn, the straw and the broken straw scattered in the field are collected. The straw is collected at a ratio of 1.05:1 per hectare of rice to straw, and then 100% of the straw is returned to the field. Specifically, the collected straw and broken straw are collected in the field, pulverized, and then compressed and granulated to obtain the straw granular fertilizer.

[0043] Then, during the autumn ploughing, the above-mentioned straw pellet fertilizer was buried in the plough layer, and then in the spring of the second year, chemical fertilizers and organic fertilizers were applied at the same time. The applied organic fertilizer is 8t / hm 2 , and as a base fertilizer once applied. Fertilizers applied include nitrogen 175kg / hm 2 , Phosphate fertilizer 70kg / hm 2 , Potas...

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...
