Complete wheat straw returning mechanical rice seedling planting method

Abstract

The invention discloses a complete wheat straw returning mechanical rice seedling planting method, which comprises the following steps of: reserving stubbles of 10 to 30 centimeters when the wheat is harvested, cutting straws to the length of 5 to 8 centimeters, and uniformly scattering the cut straws on the surface of a field; applying a base fertilizer, irrigating water for 5 to 6 centimeters to soak the field for 2 to 3 days, and embedding grass and preparing the field for two times of transverse and vertical operations through a medium tractor and a grass embedding rotary cultivator, wherein the embedded depth of the wheat straws returned to the field is 5 to 10 centimeters; settling for 2 to 3 days after grass embedding and rotary tillage operations, and then mechanically planting seedlings, wherein the mechanical seedling planting water depth is 1 to 1.5 centimeters, and the seedling planting depth is within 1.5 centimeters; and after mechanical seedling planting, performing corresponding water, fertilizer and disease, insect and weed management at the early stage, the middle stage and the later stage respectively till the rice is mature. The straws are totally left in the rice field after the wheat is harvested, and the straws are totally changed into available fertilizer by natural decomposition, so the method avoids straw burning, purifies the air, protects the environment, improves the physical and chemical properties and aggregate structure of the soil and improves the organic substance content of the soil.

Description

technical field [0001] The invention relates to a rice planting method, in particular to a rice planting method for mechanized rice seedling planting by returning the whole amount of wheat straw to the field. Background technique [0002] Whenever the wheat harvest season, "straw burning ban" becomes a key task of the government. Since no simple and feasible solution has been found, the ban is often repeated, and the surrounding areas are filled with smog. Burning straw not only pollutes the environment, wastes organic resources, but also harms soil microorganisms and organic matter. Although farmers are aware of the harm, it is time-consuming, labor-intensive, and labor-intensive to take measures such as clearing out the fields. The status quo of the season, farmers have to burn wheat grass for farming. Contents of the invention [0003] The purpose of the present invention is to provide a method for mechanized seedling planting of rice by returning full amount of wheat ...

Burning straw not only pollutes the environment, wastes organic resources, but also harms soil microorganisms and organic matter. Although farmers are aware of the harm, it is time-consuming, labor-intensive, and labor-intensive to take measures such as clearing out the fields. The current state of the season, farmers only have to burn wheat grass for plowing
