Cultivation method for directly returning full-amount rice straw to field in the western Jilin region

Abstract

The invention provides a cultivation method for directly returning full-amount rice straw to the field in the western Jilin region. The cultivation method comprises the following steps: step 1, crushing and throwing of rice straw; step 2, turning, rotating and mixing of the straw; step 3, dry spinning and leveling; step 4, field steeping in a soil saturation mode; step 5, slurry stirring; step 6, leveling; step 7, slurry settling; step 8, field management; and step 9, disease and pest control. After the rice is harvested, stubbles of the straw are thoroughly decomposed, disease aggravation cannot be caused after the straws are returned to the field through a series of treatment steps, diseases such as rice blast, banded sclerotial blight and false smut are efficiently prevented and controlled, and the effect of preventing and controlling rice-stem borers and leaf miners is remarkable; and according to the method, the decomposition rate of the rice straw returned to the field in the cold region is greatly increased, the pest damage phenomenon is reduced, the planting quality of plants returned to the field is ensured, and the method has important significance on straw resource utilization and improvement of the soil quality of the rice field.

Description

technical field [0001] The invention belongs to the field of straw returning to the field, and in particular relates to a method for directly returning the full amount of rice straw to the field for cultivation in the western area of ​​Jilin. Background technique [0002] Rice is the main food crop, and the disorderly disposal of a large amount of straw after rice harvest has caused huge damage to the environment, and also caused a waste of straw nutrient resources. In the rice areas with high temperature, the rice straw returning to the field is vigorously promoted, while the temperature in the cold area is too low, which makes it difficult to solve the problem of difficult straw decomposition, and it is difficult to realize a large amount of straw and rapid decomposition. [0003] Straw is a by-product that can be used as a resource in the farmland ecological environment. It contains nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium and organic matter r...
