Cultivation method for wedge plowing and transplanting rice

Abstract

The invention discloses a cultivation method for wedge plowing and transplanting rice, belonging to the field of rice cultivation. To solve the problem of the low yield of high-yield high-quality varieties in the exiting cultivation mode, the cultivation method of the invention comprises the following steps: (1) plowing soil; not carrying out plowing and watering after harvesting former crop in rotation; and digging a plurality of ditches on a surface of a farmland, wherein the row spacing between two adjacent ditches is 20cm, the ditch is narrow at the bottom and wide at the top and has an inverted triangular shape, the depth of the ditch is 5-10cm, the width of the ditch is 3-6cm, the two side faces of the ditch are all oblique planes relative to a horizontal plane, and the included angle alpha is 40-70 degrees between the oblique plane and the horizontal plane; (2) applying base fertilizer, transplanting seedlings, and watering; and (3) subsequently managing the field. The cultivation method of the invention reduces the farming intensity by using wedge plowing instead of traditional ploughing, applies fertilizer to the bottom of the wedge-type ditch in a centralized way, reduces the disturbance to the soil, is energy-saving and labor-saving, has large water storage capacity of the soil and high soil system stability, increases the utilization ratio of fertilizer, improves the growth environment of root system, and realizes the effects of saving cost and increasing yield and efficiency.

Description

Technical field [0001] The present invention relates to the field of rice cultivation, in particular to a rice wedge cultivation transplanting cultivation method. Background technique [0002] At present, more than 95% of the rice planting area in the south is cultivated by traditional methods. After the previous crops are harvested, the stubble and straw are burned, then soaked in water, and cultivated mechanically. Burning straw and stubble wastes resources and pollutes the environment; irrigating the slab field consumes more water (1500-3000m 3 / hm 2 ) Disrupt the ecosystem of the cultivated layer; mechanical tillage consumes energy and destroys the structure of the sand layer; it takes 3-5 days from the burning of straw to the completion of tillage, which will reduce the yield of next season by 200-400kg / hm 2 In the management process, the intensity of “double grab” (grabbing for harvest and seeding) is increased; during the management process, shallow application of base fert...

Problems solved by technology

At present, a large number of high-yield and high-quality varieties have been popularized and applied, but the cultivation methods are not matched, especially the cultivation methods are not matched, which makes it difficult to realize the yield potential of the varieties
