Multiple-cropping and no-tillage cultivation method of potato-direct seeding rice

Abstract

The invention discloses a multiple-cropping and no-tillage cultivation method of potato-direct seeding rice, belongs to a cultivation method of crops, and is applicable to seasonal southern rice regions. The multiple-cropping and no-tillage cultivation method comprises the steps of: rice straw is stored when the rice is harvested, the potatoes are covered for the whole no-tillage cultivation process, the straw and stem leaves of potatoes are flatly laid on borders when the potatoes are harvested, and the straw and stem leaves are watered and soaked and dried before the rice is sowed; and no-tillage direct seeding of rice is carried out in ridges, the water control irrigation method is adopted in the rice growing process, weeds are killed for only once, and simultaneously the fertilizing amount is reduced by 30 percent. The multiple-cropping and no-tillage cultivation method of potato-direct seeding rice tightly combines straw-covering no-tillage cultivation of potatoes with no-tillage direct seeding cultivation of rice, and realizes annual zero tillage of the rice field, fully cyclic utilization of straws of crops and reduced application of fertilizer and weed killer. In the technology disclosed by the invention, the resources of the rice fields such as soil, light and temperature are fully utilized, land utilization and land maintenance are combined, and high economic benefit is achieved; and the multiple-cropping and no-tillage cultivation method is characterized by labor saving, cost reduction, high yield, high efficiency and environment protection.

Description

technical field [0001] The invention relates to a cultivation method of crops, in particular to a no-tillage cultivation method for multiple cropping of potato-direct-directed rice. Background technique [0002] It has always been a research hotspot to develop labor-saving, cost-saving, high-efficiency paddy farming models and new technologies, and to improve the economic benefits of paddy fields. At present, potatoes have attracted much attention due to their high yield and high economic benefits, and researchers have conducted a lot of research on their labor-saving and cost-effective cultivation techniques. The Institute of Dry Farming of the Guangdong Academy of Agricultural Sciences carried out soil cultivation experiments on winter-planted potatoes covered with rice straw from 1988 to 1989; A new technology for high-yield and high-education cultivation of autumn potatoes that integrates large technologies; in 2001, the China Rice Research Institute improved the techno...

Problems solved by technology

However, although direct-seeding rice has the advantages of saving labor and cost, it also has a big disadvantage, that is, it is highly dependent on chemical herbicides, especially no-tillage direct-seeding rice.

Efficient chemical weeding is one of the reasons for the rapid promotion of direct-seeding rice, but the disadvantages of chemical control, which often cause phytotoxicity, damage seedlings, and pollute the environment, cannot be ignored
