High-efficiency cultivation method for rice with double-sided double-deep sorting and fertilization by machine transplanting on ridges and double rows

Abstract

The invention belongs to the technical field of rice cultivation, and in particular relates to a double-row high-efficiency cultivation method for rice with bilateral double-deep sorting and fertilization on ridges. Carry out dry ridging by fertilizing dry ridging machinery; the width of the bottom 7 of the dry ridging is 50 to 60 centimeters, the height of the ridge 6 after suppression is 11 to 13 centimeters, and the width of the ridge surface 4 after suppression is 30 to 40 centimeters; The two sides of seedling band 2 are distributed with deep fat band 3 and shallow fat band 1, and the height of deep fat band 3 apart from ridge surface 4 is 6 to 8 centimetres, and the width of deep fat band 3 apart from seedling band 2 is 8 to 15 centimeters, The height of the shallow fertilizer zone 1 from the ridge surface 4 is 3 to 5 centimeters, and the width of the shallow fertilizer zone 1 from the seedling zone 2 is 3 centimeters; The distance between the double row seedling belts 2 after insertion is 16 to 30 centimeters; the deep fertilizer belt 3 is applied with slow-acting fertilizer, and the shallow fertilizer belt 1 is applied with quick-acting fertilizer. The invention saves fertilizer, fertilizes the soil, seizes farming time, increases production efficiently, saves time and labor, and reduces cost.

Description

Technical field: [0001] The invention belongs to the technical field of rice cultivation, and in particular relates to a double-row high-efficiency cultivation method for rice with bilateral double-deep sorting and fertilization on ridges. Background technique: [0002] Rice is one of the most important food crops in my country, and japonica rice is very popular for its excellent quality. Since 2004, the rice planting area in Heilongjiang Province has expanded rapidly, becoming the main production area of ​​high-quality japonica rice with the largest planting area and the best ecological environment in the country. By 2015, the planting area has reached 4.33 million hectares, which is an important contribution to national food security and economic development of Heilongjiang Province. made a great contribution. [0003] However, in order to continuously pursue high yields, people consider the growth status of the aboveground part of rice. They mainly research and apply it ...

Problems solved by technology

In this process, the soil is mixed with water to make the soil into a paste, resulting in too fine mud, destroying the soil aggregate structure, long settling time, increasing soil firmness, significantly reducing soil density and permeability, and hindering the growth of rice. Growth; large-scale application of chemical fertilizers in the whole layer will greatly reduce the utilization rate of fertilizers, pollute the environment, and the fertile black soil will gradually become barren and hardened; it will take a long time from soaking the field to transplanting rice seedlings, resulting in waste of water resources; root stubble and weeds floating on the field surface, It is easy to drag piles or get entangled on the seedlings during manual or machine transplanting. Farmers must pick up the root stubble and place it on the ridge of the paddy field to carry out the transplanting operation. It is beneficial to fertilize the soil, and flat farming is not conducive to warming the soil in cold regions

[0005] Therefore, the existing cultivation measures in paddy fields have seriously restricted the yield and quality of rice, which is not conducive to the "three reductions" cultivation proposed by the Ministry of Agriculture, let alone Conducive to the efficient and safe production of rice and the sustainable development of agriculture
