Embodiment Construction

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019]Wheat interplanting, water-saving and drought-resistant rice no-tillage cultivation techniques, including selection of wheat fields, selection of varieties, determination of suitable sowing time, seed treatment, sowing, management during inter-sowing, appropriate harvest, seedling management and tillering management after wheat harvest The selection of the wheat field: the wheat field that adopts wheat interplanting rice must be rice and wheat two ripe field pieces at first, and secondly should select the flat wheat field that field irrigation and drainage is convenient, and weeds are few. The width of the border should be 2-2.5 meters, so that it is n...

Abstract

The invention relates to a wheat interplanting water-saving drought-resistant rice no-tillage cultivation technology. The no-tillage cultivation technology comprises the steps of wheat field selection, selection of varieties, determination of an appropriate sowing period, seed treatment, sowing, management in a seeding period, harvesting in an appropriate period, seedling stage management after wheat harvesting, and management of the tillering period. The technology has the advantages that water-saving and drought-resistant rice has the strong rooting capacity and drought resistance, irrigation is not needed, the characteristics in the whole growth period of rice can be met by means of natural rainfall only, the complex procedures of traditional ploughing and soil preparation, seedling raising and transplanting and the like are omitted, the cultivation procedure is simplified, conflicts between stubbles, seasons and water resources are relieved, and the labor intensity is reduced; meanwhile, the conflict of labor shortage is relieved, and the technology saves rice field, labor force, water, labor and cost and improves efficiency. Besides, severe environment pollution problems caused by straw incineration in a wheat region are effectively solved, the content of organic substances in soil is increased, the soil fertility is improved, and the physical and chemical properties of the soil are improved.

Description

technical field [0001] The invention relates to the technical field of rice cultivation, in particular to the no-tillage cultivation technology of wheat interplanting, water-saving and drought-resistant rice. Background technique [0002] Rice is a kind of herbaceous Oryza genus, and it is also the most important and oldest kind of grain in Oryza genus. It is also called Asian cultivated rice, and it can be said to be rice in simple terms. It is an annual, gramineous plant, monocotyledonous, sexually warm and humid, about 1 meter high when mature, with slender leaves, about 50 to 100 cm long and 2 to 2.5 cm wide. The flowers of rice are very small. When blooming, the main flowering branches will be arched, and small flowers will bloom between 30 and 50 cm below the branches. Most of them are self-pollinating and set seeds, which are called rice spikes. The size of general rice ear is 5 to 12 millimeters long, 2 to 3 millimeters thickness; The yield per mu of existing rice c...
