Embodiment Construction

[0050] A rice wedge cultivation and transplanting cultivation method, including soil cultivation, application of basal fertilizer, transplanting seedlings, watering, and three steps of field management: no plowing and no watering after harvest; figure 1 As shown, a wedge-shaped object is used to scribe a groove with a row spacing of 20cm. The groove is wide on the top and narrow on the bottom, in an inverted triangle, 10cm deep and 5cm wide. Both sides of the groove are inclined planes relative to the horizontal plane. The angle between the inclined plane and the horizontal plane α is 40°~70°; apply basal fertilizer in the furrow, including organic fertilizer, urea, potash fertilizer, phosphate fertilizer, silicon fertilizer, zinc fertilizer; cover a layer of 1-2cm thick soil after applying basal fertilizer; seedlings with soil grown from floppy disks Throw into the ditch, the roots enter the ditch, the stems and leaves of the seedlings are outside the ditch, and one row of 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 southern China is cultivated by traditional methods. After the previous crops are harvested, the stubble and straw are burned, then soaked in water, and tilled 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) has been increased; during the management process, shallow application of ba...
