Method for culturing late rice by interplanting and direct-sowing early rice

Abstract

The invention discloses a method for culturing late rice by interplanting and direct-sowing early rice. The method comprises the following steps of: interplanting and direct-sowing late rice seeds in a rice field 5 to 12 days before harvesting the early rice; within one week after harvesting the early rice, fertilizing for the first time and preventing and controlling weeds by selecting a weedicide; fertilizing for the second time about 15 days after fertilizing for the first time; fertilizing for the third time in a booting stage; preventing and controlling plant diseases and insect pests byadopting technology of raising ducks in the rice field, a physical method or a medicament; and harvesting timely after maturity. By using the method, time is gained for autumn sowing; crops for rotation and agricultural consumption are eliminated; and labor and seasonal stress is relieved; the late rice is sown by a machine directly so as to reduce labor intensity and improve work efficiency; thelate rice is accelerated to sprout early and grown fast; weed emergence is uniform so that the weedicide has a good effect; and non-tillage cultivation contributes to improving soil physical and chemical properties and keeping a soil granular structure.

Description

technical field [0001] The invention relates to a method for cultivating rice, in particular to a method for cultivating late rice in which strips are directly broadcast in early rice. Background technique [0002] Rice is an important food crop in southern my country. In the long-term rice production practice, the working people have accumulated various forms of rice planting methods, mainly including rice field transplanting, throwing seedlings and direct seeding after early rice harvest, but these planting methods have stubble changing period, transplanting and throwing seedlings. There are also methods of transplanting and growing period of agricultural consumption. At the same time, the traditional planting method of paddy field plowing is easy to damage the soil plow layer, reduce the performance of water and fertilizer retention, and is time-consuming, labor-intensive, and low-efficiency; in recent years, with the reform of production methods, the development of rice...

Problems solved by technology

[0003] In order to overcome the existing cultivation methods that cannot effectively solve the contradictions such as seasonal tension caused by stubble sowing in autumn, labor shortage and agricultural consumption during the growth period caused by the cultivation method, the present invention aims to provide a late rice cultivation method for direct seeding in early rice. The method can make full use of the climatic conditions suitable for sowing and emergence of late rice before harvest in the early rice field, and create a good basic condition for autumn sowing. The no-tillage and direct-seeding late rice in the paddy field can make good use of temperature, light, water, and air conditions, and reduce labor intensity. Save time, improve work efficiency, eliminate stubble and agricultural consumption, stabilize production and increase efficiency
