Abstract
The invention discloses an early rice cultivation method. The method includes the steps of seed selection and seedling sowing, sturdy seedling cultivation, seedling planting in a rice field and rice cultivation, wherein seedling planting in the rice field includes the steps of rice field farming and seedling cutting, rice field farming includes the step of dividing the rice field into early rice planting parts and anti-pest crop planting parts, the early rice planting parts and the anti-pest crop planting parts are arranged in a staggered mode at intervals, and anti-pest crops comprise insect repellent chrysanthemum and/or wormwood. Due to the fact that the rice field is divided into the early rice planting parts and the anti-pest crop planting parts, rice and the insect repellent chrysanthemum and/or the wormwood are planted on the early rice planting parts and the anti-pest crop planting parts respectively, insect pests of the rice mainly occur in the period between the earring stage and the milk-ripe stage, the growth mature period of the wormwood and the insect repellent chrysanthemum is consistent with the period between the earring stage and the milk-ripe stage of early rice, and then the mature insect repellent chrysanthemum and/or the wormwoods can achieve the effect of preventing and repelling insects in the period between the earring stage and the milk-ripe stage of the early rice. The wormwood and the insect repellent chrysanthemum are also commercial crops, so that economic benefits for planting the early rice are improved.
Description
Technical field
The present invention relates to field of rice cultivation, be specifically related to a kind of early rice cultivation method.
Background technology
Paddy rice is a kind of important food resource, and the people in many places, the whole world relies on it as staple food, especially in China.The sowing area of China paddy rice accounts for about percent 29% of all cereal crops, about 60 percent population is arranged approximately all as staple food.But China population growth is rapid at present, and arable area continues to reduce, and this also poses a big pressure to cultivation, the supply of paddy rice.Make us in certain arable area, cultivate the more rice crop of high yield, high-quality, could guarantee the rice yield of China like this.Paddy rice can be divided into early rice, semilate rice and late rice, wherein early rice 6, the harvesting in July.
Chemical pesticide can effectively improve the output of paddy rice plantation, but that the problem of environmental pollution that the use of agricultural chemicals brings and food-safety problem also more and more come is more serious.Particularly to this class crop of paddy rice, water and soil pollution and residue of pesticide harm that the use of its agricultural chemicals causes are also even more serious, therefore are necessary to provide a kind of early rice cultivation method, under the situation of not using agricultural chemicals, can prevent and treat damage by disease and insect, improve the output of paddy rice.
Summary of the invention
The purpose of this invention is to provide a kind of early rice cultivation method, it utilizes diversity of organism, can prevent and treat damage by disease and insect under the situation of not using agricultural chemicals, improves the output of paddy rice.
For achieving the above object, the present invention adopts following technical scheme:
A kind of early rice cultivation method, it comprises that seedling, the strong seedling of cultivation are broadcast in seed selection, transplant seedlings in the rice field and paddy rice is cultivated, wherein transplant seedlings and comprise the cuttage of rice field farming and rice shoot in the rice field, the rice field farming is that the rice field is divided into early rice plantation piece and pest control crop-planting piece, early rice plantation piece and pest control crop-planting piece are the interleaved shape and arrange that the pest control crop comprises expelling parasite chrysanthemum and/or wormwood.
By the rice field being divided into early rice plantation piece and pest control crop-planting piece, early rice plantation piece and pest control crop-planting piece difference rice cultivation and expelling parasite chrysanthemum and/or wormwood, the insect pest of paddy rice mainly occurs in out fringe between milk ripe stage, and the growth and maturity phase of wormwood, expelling parasite chrysanthemum and early rice to go out fringe consistent to time milk ripe stage, go out fringe during the milk ripe stage in early rice like this, the expelling parasite chrysanthemum of growth and maturity and/or wormwood just can play the effect of control expelling parasite, simultaneously, wormwood, expelling parasite chrysanthemum also are good economic crops, improve the economic benefit of early rice plantation.
