Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, the method for disinfection and pH adjustment of the full amount of rice straw returning to the field soil of the embodiment of the present invention comprises the following steps:

[0023] S101: crushing straw. After the rice is mature, use the combine harvester to harvest the rice and crush the straw and return it to the field. During the operation, the stubble is generally about 15cm, and the length of the crushed straw is recommended to be 5-10cm...

Abstract

The invention discloses a method for disinfection and pH regulation of total straw application soil. The method for disinfection and pH regulation of the total straw application soil comprises the following step of smashing straw; after rice is ripe, utilizing a combine harvester to perform rice harvesting and straw smashing and returning to fields; performing combined application of decomposition agent and then turning over the fields; and dispersing quicklime and lime nitrogen. According to the method, the pH of the total straw application soil can be improved effectively, the straw decomposition speed is quickened, poisonous and harmful microorganisms and harmful bacteria are effectively killed, the N element content of the soil is increased, and the method is favorable for healthy growth of succession crop (late rice).

Description

technical field [0001] The invention belongs to the technical field of straw returning to the field, and in particular relates to a method for disinfecting the soil and adjusting the acidity and alkalinity of returning a full amount of straw to the field. Background technique [0002] About 50% of agricultural input elements are finally converted into crop straw. The waste of straw resources is essentially the waste of cultivated land, water resources and agricultural inputs. Increase the research and development of new technologies for the utilization of agricultural waste such as straw, scientifically and efficiently use straw resources, and prohibit the burning of straw. economic advantage. On the other hand, it can protect the environment, protect people's health, and keep traffic and civil aviation running smoothly. It is an important measure for building a resource-saving and environment-friendly society. Straw burning is extremely harmful, and the main hazard is ai...
