Rice and onion integrated rotation method using same machine in dry farmland

Abstract

The invention relates to a rice and onion integrated rotation method using the same machine in dry farmland. According to the method, the same transplanter is utilized, and dry farmland rice pot seedlings and onions are subjected to rotation in special crops of rotation in a double cropped region. In the rotation process of dry farmland rice and the onions, seedling raising pot trays and the transplanter can be annually used, the same equipment, the same field and the same machine are used for seedling raising and planting, mechanical integration is achieved, the investment cost is reduced, the problems that traditional rice-wheat rotation is short in rotation crop conversion period and steeping field straw floats are changed, the rice yield is increased, the output value of the onions isimproved, meanwhile, a lot of water is saved, and diseases of rice are greatly reduced.

Description

technical field [0001] The invention relates to an integrated crop rotation method for rice and onion in the same dry field with the same machine, and belongs to the technical field of agricultural crop cultivation. Background technique [0002] Existing paddy rice planting is paddy field transplanting, and the transplanting mode has artificial transplanting, artificial throwing, mechanical transplanting and mechanical throwing and so on. The irrigation volume of rice is more than that of other upland crops, but the water consumption of rice fields is mostly used for hydroponic field before transplanting and evaporation between trees and field infiltration during rice growth. In fact, its physiological water requirement is not much. About 1 / 3 to 2 / 3 is used for farming and ecological water, which has great potential for water saving (Xiao Yujiang, 1985; Wu Boshun et al., 1985). The irrigation quota during the growth period of dry rice is 3000m per hectare 3 A higher yield ...

AI Technical Summary

Problems solved by technology

⑤Under the background of my country's "double reduction" action and zero growth in chemical fertilizer use, the application of manure and other organic fertilizers will increase significantly, but the application of manure will be more difficult and time-limited when paddy fields are covered with water. Dry planting seedlings and dry farming can overcome the problem of difficult application of water-based organic fertilizers

In areas with two crops a year, such as Shandong, the most common is the rotation of rice and winter wheat. This type of rice-wheat rotation is planted all year round, and the mode is single, which makes the root rot and scab of wheat more and more serious.
