Method for overcoming successive cropping obstacle of North rice

Abstract

The invention discloses a method for overcoming successive cropping obstacle of North rice. The method comprises the following steps: after vegetables are harvested, ploughing the soil to keep the moisture content of the soil on the plough layer below 17 percent; if the moisture content of the soil exceeds 17 percent, drying the soil in the sun in sunny days till the moisture content of the soil is less than 17 percent; paving a layer of dry crop straws on the ploughed soil according to the use amount of the straws that 60 to 100 kg of the crop straws are paved to the soil with the area of 4 to 5 m<2>, paving a thin layer of soil on the crop straws, and igniting the straws exposed outside to burn the straws, wherein with the burning of the straws, the soil on the straws continuously drops down to cover the burning straws, so that the burning of the straws is slowed down till all the straws are burnt; after the straws are burnt completely, carrying out deep ploughing uniformly, applying white rot fungi into the surface layer of the soil, which is 10 to 30 cm in depth, according to an amount of 400 to 500 g / m<2>, carrying out ploughing, and watering to keep the soil wet; and carrying out ridging and furrowing.

Description

technical field [0001] The invention belongs to the technical field of soil fertilizer in agriculture, and in particular relates to a method for overcoming obstacles to rice continuous cropping in the north. Background technique [0002] Continuous cropping obstacle refers to the phenomenon of weaker growth potential, lower yield, and lower quality of rice when rice of the same species or family is continuously cultivated in the same land, which has the characteristics of accumulation, regionality, and crop specificity. With the continuation of China's rice industry, coupled with the requirements of rice on natural factors such as temperature, light, moisture, and soil types, as well as producers' planting habits and market distribution, rice production is limited to a certain area, and rice production is restricted to certain areas. The phenomenon of rice continuous cropping obstacles is becoming more and more serious, especially with the industrialization, specialization, ...

Problems solved by technology

Rice continuous cropping obstacles and their hazards are very common. Except for long-term crop rotation, it is difficult to completely solve the problem through one or a few measures. Rice continuous cropping obstacles often cause a large reduction in rice production or even no harvest, causing huge economic losses to vegetable farmers. Continuous cropping obstacles lead to a large number of rice diseases and insect pests, resulting in excessive use of pesticides, polluting the environment, and making the living environment of humans worse
