Rice-pakchoi crop rotation method in middle and lower reaches of Yangtze river

Abstract

The invention provides a rice-pakchoi crop rotation method in the middle and lower reaches of the Yangtze river. At first, a shed building method is improved; furthermore, rice is planted in summer, and a shed is built and proper species of pakchoi is planted in winter. According to the rice-pakchoi crop rotation method, the shed is firm and durable; meanwhile, the structure is greatly simplified, and the manufacturing cost is lower; the shed is convenient to assemble and disassemble; the labor and the time can be greatly saved for the crop rotation method; the rice can be planted in time in the crop rotation process, and stubbles can be immediately emptied out to plant the pakchoi in the shed in time, so that the crops can be sold in the market in proper time, and the selling price is high; the economical benefit of the rice-pakchoi crop rotation method is more outstanding.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a rice-pakchoy rotation method in the middle and lower reaches of the Yangtze River. Background technique [0002] Since the per capita arable land of farmers in the middle and lower reaches of the Yangtze River is only 1.0 to 1.5 mu, the "rice-wheat" crop rotation mode is generally adopted in agricultural food production, that is, summer sowing rice is harvested in autumn and winter wheat is planted. However, the problems of this crop rotation mode are: (1) The purchase price of wheat is low, 2.2 to 2.4 yuan per kg; Affect yield; (3) The wheat growth period is long, from sowing in early and mid-November to harvesting in mid-May, 180-190 days long, and the management of the farm is large. (4) Wheat 667m 2 The output is about 300kg, and the output value is 600-700 yuan, after deducting the agricultural cost, 667m 2 The net benefit is about 200 yuan, etc., result...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a rice-pakchoy rotation method in the middle and lower reaches of the Yangtze River. By using a new greenhouse construction method in the rotation process, the existing greenhouses either have a short service life, are not strong, or have a complex structure. The difficulty of disassembly and assembly makes the cost of facilities lower in the crop rotation method, the selection and matching of crop types has more economic advantages, and it can better ensure the balance between supply and demand between products and the market
