Abstract

The invention relates to a method for preventing and curing vegetable soil continuous cropping obstacle by crop straw, comprising the following operating steps: 1, after vegetable is harvested, plowing soil; 2, spreading one layer of dry crop straws on plowed soil, wherein straw use level is characterized in that 80-150 kg of crop straws are spread on the soil with the area of 5m<2>; 3, covering soil near the periphery plough layer out of soil spread with the straws on the straws, and causing straws in the periphery to expose outwards; 4, igniting straws which expose outwards to burn the straws; and 5, cleaning soil from the position 15 cm below the straw until upper unburned straws expose, which is favorable for straws to continue burning, and carrying out circulation operation until all straws are burnt up. The method provided by the invention has obvious production increase effect on new and old vegetable plots and especially has obvious effect on improving old vegetable plots. Because the invention disinfects soil to cause degraded soil to restore health, the method in the invention also has obvious effect on improving non-vegetable soil continuous cropping soil.

Description

technical field

[0001] The invention belongs to the technical field of soil fertilizer in agriculture, and in particular relates to a method for improving soil continuous cropping obstacles. Background technique

[0002] Vegetable continuous cropping obstacle refers to the phenomenon that when the same species or the same family of vegetables are continuously cultivated in the same field, the growth potential of vegetables will be weakened, the yield will be reduced, and the quality will be reduced. It has the characteristics of accumulation, regionality and crop specificity. With the continuation of China's vegetable industry, coupled with the requirements of vegetables on natural factors such as temperature, light, moisture, and soil types, as well as the planting habits of producers and market distribution, vegetable production is limited to a certain area, and there have been emergences across the country. The phenomenon of vegetable continuous cropping obstacles is beco...
