Rice cultivation method

Abstract

The invention discloses a rice cultivation method. The rice cultivation method comprises the steps of (1) treatment of a former crop of crop straw, (2) excavation of ditches and management of water, (3) construction of anti-escape facility, (4) base application of bottom fertilizer, (5) sowing of early rice and management of a field; (6) release and breeding of fish fry, earthworm larvae, chicks,young ducks and goslings, (7) harvest of the early rice and sowing of late rice, (8) field management of the late rice, (9) harvest of the late rice and sowing of Pisum sativum and (10) field management and harvest of Pisum sativum. According to the method, three ripening wide-compartment crop rotation of rice, rice and fresh Pisum sativum is the core, and breeding of earthworms, chickens, ducks,geese and fishes is adopted for supplementation, so that large-scale sustainable production of rice is achieved, and the benefits of a rice paddy is improved significantly while grain production is stabilized; not only can change of the plant structure of the rice paddy and a high economic value, a high ornamental value and a good field fertilization effect be achieved through newly introduced Pisum sativum with green fruit as the harvest purpose, but also the structure of the rice paddy can be changed, so that the animal biomass is increased.

Description

technical field [0001] The invention relates to a rice field rotation cultivation management method, in particular to a rice cultivation method. Background technique [0002] According to statistics, in 2017, the total annual output of rice in my country was about 200 million tons. Rice showed high yield, high purchase volume, and high inventory, and there was a situation of "overproduction" in some places. In the context of rising rice imports and falling rice prices, the benefits of monoculture rice are relatively low. The phenomenon of increasing production without increasing income has affected farmers' enthusiasm for growing grain, resulting in the abandonment of some low-yielding fields, which is extremely detrimental to national food security. [0003] 200 million tons of rice can produce 240 million tons of straw (estimated at a grain-to-straw ratio of 1:1.2), which contains a large amount of organic matter, nitrogen, phosphorus, potassium, and trace elements. The n...

Problems solved by technology

[0006] Aiming at the problems of low output value, low net profit, high production intensity, high natural risk, large amount of water, fertilizer and medicine in the production process, difficulty in returning crop straw to the field, difficulty in controlling diseases, insect pests and weeds, and difficulty in timely operation according to the annual farming season , the present invention provides a rice farming method that can realize value-added and income increase, reduce farming intensity and improve the ability to resist natural risks, effectively control diseases, insect pests and weeds, return full amount of straw to the field, and operate timely every year
