Rice cropping method under condition of wheat straw returning to field

Abstract

The invention discloses a rice cropping method under a condition of wheat straw returning to the field. The method comprises the following steps that S1, wheat straws return to the field; S2, a base fertilizer is evenly broadcasted on the surfaces of the wheat straws, rotary tillage is carried out instantly, the tilling depth is 18-22 centimeters; S3, water feeding is carried out to soak the field, after the soil absorbs enough water, a water rake is used for harrowing for 1-2 times; rice planting is carried out after slurry subsides completely, irrigation is carried out after rice planting until the water depth is 3-5 centimeters, 2-3 days after the rice planting, nitrogen topdressing is carried out timely and separately; after the water in the field is naturally consumed completely, airdrying is carried out on the field for 1-2 days, then the rice is irrigated by adopting a rice wet irrigation method; S4, nitrogen topdressing is carried out in the later stage. Compared with the prior art, the rice cropping method under the condition of wheat straw returning to the field has the advantages that the rice cropping method solves the problems that the decomposition of the wheat straws in the early stage inhibits the growth of the rice, and poison gas generated during wheat straw decomposition damages the roots; the yield and quality of the rice are improved, and the cost and useamount of the fertilizer are reduced.

Description

technical field [0001] The invention belongs to the technical field of rice cultivation, and in particular relates to a rice cultivation method under the condition of returning wheat straw to the field. Background technique [0002] Straw is the main by-product of crops, and it is also an important renewable organic resource, which is rich in nutrients such as carbon, nitrogen, phosphorus, potassium and trace elements. Straw returning to the field is a direct and effective way to utilize straw resources. Straw returning to the field can increase soil organic matter, improve soil structure, promote microbial activity and the development of crop root systems, while avoiding air pollution and resource waste caused by burning straw, it also has the effect of increasing fertilizer and production. Therefore, returning straw to the field is an effective measure to fertilize the soil, improve the soil, and achieve sustainable agricultural development. [0003] At present, the exis...

Problems solved by technology

The disadvantage of this method is that frequent plowing will easily cause water and soil loss, and the straw will be directly buried in the soil, and it will easily produce harmful gas when it is decomposed, which will cause poison to the rice seedlings; in the soil

The disadvantage of this method is that it is troublesome, the economic benefit is low, and it is not easy for farmers to accept it; (3) The livestock are returned to the field, that is, the straw is fed to the livestock and turned into fertilizer and returned to the field.

The disadvantage of this method is that it is difficult to implement on a large scale

Moreover, in the process of returning wheat straw to the field, there is still the problem that the straw will inhibit the growth of rice in the early stage
