Embodiment Construction
[0056] A kind of cultivation method of paddy tillage spot direct seeding comprises soil tillage, pretreatment of rice seeds, application of basal manure and spot direct seeding, watering, and field management in four steps: no plowing and no irrigation after harvesting of previous stubble; figure 1 As shown, use a wedge-shaped object to carve a groove with a line spacing of 20cm. The groove is wide at the top and narrow at the bottom. figure 2 with image 3 The shown inverted triangle is 10cm deep and 5cm wide. Both sides of the ditch are sloped relative to the horizontal plane, and the angle α between the slope and the horizontal plane is 40° to 70°; Apply base fertilizers, including organic fertilizers, compound fertilizers, silicon fertilizers, and zinc fertilizers; cover with a layer of 1-2cm thick thin soil after applying base fertilizers; sow pretreated rice seeds into furrows, and a furrow is 1 row of rice. The direction of performing is consistent with the extension ...

The invention discloses a cultivation method for rice direct dibble seeding in wedged ditches, which belongs to the field of rice cultivation. In order to solve the problem that yield potential of high-yield high-quality varieties is difficult to fulfill by existing cultivation methods, the cultivation method for rice direct dibble seeding in wedged ditches includes the steps: firstly, tilling soil, namely performing no turning or irrigation after preceding harvesting, and digging a field to obtain a plurality of ditches, wherein row spacing between each two adjacent ditches is 18-22cm, each ditch in a triangular shape is wide end up, each ditch is 5-20cm deep and 3-6cm wide, two sides of each ditch are slopes relative to the horizontal plane, and an included angle between each slope and the horizontal plane is 40 DEG-70 DEG; secondly, post-treating rice seeds; thirdly, performing base fertilizer application, direct dibble seeding, and irrigation; and fourthly, performing field management. The traditional ploughing is replaced with wedging, so that farming intensity is reduced, interference to soil is lowered, energy sources are saved, labor is reduced, seeds for use are few, soilwater retention capacity is high, soil system stable is high, fertilizer utilization rate is high, root system growth environment is improved, and cost reducing, yield increase and efficiency enhancement are achieved.
Description
technical field [0001] The invention relates to the field of rice cultivation, in particular to a direct-seeding cultivation method of rice tillage points. Background technique [0002] At present, more than 95% of the rice planting area in the south is cultivated by the traditional method. After the previous crop is harvested, the stubble and straw are first burned, then soaked in water, and mechanically plowed. It is characterized by burning straw and stubble, wasting resources and polluting the environment; soaking slab fields with water consumes a lot of water (1500-3000m 3 / hm 2 ), disturb the ecosystem of the cultivated layer; mechanical plowing consumes energy and destroys the sand layer structure; traditional live broadcast methods are mainly scattered live broadcast, with a large amount of seeds, and excessive growth groups in the later stage may easily cause lodging and outbreaks of diseases and insect pests; during the management process Shallow application of b...
