Film mulching and soil covering dry farming method for rice in cold region

Abstract

The invention provides a film mulching and soil covering dry farming method for rice in a cold region. The method comprises the following steps: (1) soil preparation stage before seed sowing: carryingout autumn soil preparation on the to-be-sowed ground and carrying out one-turning-two-rotating or deep-loosening-two-rotating so that the to-be-sowed ground is flat, soil blocks are fine and brokenand the ground is in a to-be-sowed state; (2) film mulching: adhering rice seeds to fertilizers by using environmentally friendly glue on a biodegradable film and then storing the film for mulching; (3) film mulching and soil covering: applying a seed fertilizer and a base fertilizer into soil of the to-be-sowed ground, laying the biodegradable film adhered with the rice seeds in step (2) on the ground, covering the film with soil and then pressing to ensure soil moisture content of the soil and early emergence; and (4) after management: carrying out leaf fertilizer application management, disease management, insect management and water replenishing management after sowing the seeds and before harvesting, and then harvesting the rice. The method is water-saving, labor-saving, environmentally friendly, economical and simple, meanwhile, complicated and difficult links of seedling culture, rice transplanting, weeding and the like are omitted, and a planting procedure is simplified reasonably.

Description

technical field [0001] The invention relates to a method for dry farming of rice covered with film and soil in cold regions, and belongs to the technical field of agricultural planting. Background technique [0002] Rice is the most important food crop in my country. About 70% of my country's agricultural water is used for rice irrigation. However, with the growth of population, the development of cities and industries, the change of global climate and the increase of environmental pollution, the water used for crop irrigation The increasing scarcity of water resources seriously threatens the development of crops, especially rice production. Therefore, the direct seeding planting method of paddy rice dry land enters people's realization gradually, and the direct seeding planting of rice dry land refers to the technology of directly sowing seed in dry field (or paddy field Honda) without raising seedlings and transplanting seedlings in the rice cultivation process, and the tec...

[0002] Rice is the most important food crop in my country. About 70% of my country's agricultural water is used for rice irrigation. However, with the growth of population, the development of cities and industries, the change of global climate and the increase of environmental pollution, the water used for crop irrigation Increasing scarcity of water resources seriously threatens the development of crops, especially rice production

Therefore, the direct seeding planting method of paddy rice dry land enters people's realization gradually, and the direct seeding planting of rice dry land refers to the technology of directly sowing seed in dry field (or paddy field Honda) without raising seedlings and transplanting seedlings in the rice cultivation process, and the technology of cultivating rice with Compared with transplanting rice seedlings, this technology has the advantages of water saving, labor saving, time saving, cost saving, and efficiency enhancement. It shows a trend of gradual development and expansion. However, there are still many problems in the cultivation of rice dry farming, such as dry land preparation is laborious and difficult, it is easy to breed weeds, and the effect of artificial weeding is poor, etc.
