Embodiment 1

[0050] A kind of paddy rice upland cultivation method, concrete operation is as follows:

[0051] ⑴ Site selection

[0052] Select loam or sandy loam fields with a pH of 6.0 to 6.5, a salt content of 0.08% to 0.1%, and a chloride content of 0.08% to 0.10%, and avoid continuous cropping for more than 2 years;

[0053] ⑵ land preparation

[0054] Tilling: when the field water holding capacity of the soil reaches below 50%, the plowing depth is 10cm for high-shuang fields and 15cm for low-lying and waterlogged fields;

[0055] Flat field: For fields that are supplied with water by flood irrigation, the height difference of the field surface shall be within 3cm; for fields that are supplied with water by sprinkler irrigation or drip pipes, no flat field operation shall be performed;

[0056] Broken soil: crush the soil after flattening, so that the diameter of the soil block is less than 2cm;

[0057] ⑶ species selection

[0058] Choose suitable plants with strong germination ...

Abstract

The invention discloses a dry-farming cultivation method for rice. The dry-farming cultivation method comprises the steps such as soil selection, soil preparation, seed selection, seed pretreatment, sowing, fertilization, water management, weeding as well as disease and pest control, wherein the seed pretreatment step further comprises the steps such as seed drying, seed sorting by salt water, coating, seed soaking for disinfection, seed dressing and germination acceleration. By using the method, the defects of complex cultivation process, high cost input and incapability of realizing large-scale popularization and application during dry-farming cultivation of rice can be effectively overcome.

Description

technical field [0001] The invention relates to the technical field of rice cultivation, in particular to a rice cultivation method under dry farming. Background technique [0002] Rice is one of the main food crops in my country, and 2 / 3 of the population in China takes rice as a staple food. At present, my country's rice production is mainly based on transplanting, which has the advantages of ensuring stable and high yields of rice, but at the same time has the disadvantages of labor-intensive, low water resource utilization, and low production efficiency. In recent years, labor shortage and water shortage have become constraints affecting the sustainable development of rice in some areas. Therefore, using the existing production conditions and resource environment to develop dry rice cultivation in suitable areas is a feasible way to solve this problem. The rice dry-farming cultivation technique does not go through seedling raising and transplanting, but directly carrie...
