Description
Technical field
The present invention relates to the Weeds distribution side during a kind of agricultural production, more particularly to a kind of manufacture of organic rice
Method.
Background technology
Oryza sativa L. is one of staple food crop of China, in occupation of consequence all the more in national life, while
Irreplaceable effect is played in China's food supply is solved.But in the state of development of Oryza sativa L., China Oryza sativa L.
Also there are some common problems in plantation, limit the development of Rice Cropping industry.At present there is overfertilization in China's Rice Cropping
Phenomenon, at the site preparation initial stage, just to apply base manure, apply tillering fertilizer after rice striking root early, in leaf age index 91 or so also
Ear manuer need to be imposed, Later Stage of Rice can also as one sees fit apply granulated fertilizer, and according to the different trophophase of Oryza sativa L., applying fertilizer type is various, so
And, accelerate as China rural holding is reversed, increasing farming rich and influential family is emerged, agricultural is just quick towards industrialization direction
Development, adds China peasant and goes down town in a large number and work, and causes that rural area person between twenty and fifty labour force's is in short supply, in causing scale agricultural production
Human cost increases, if Oryza sativa L. needs repeatedly fertilising, not only time-consuming, plant growth manuring late inconvenience, production cost
Increase, and rest in soil element more after applying fertilizer, in the course of time so that certain element excess in soil, apply fertilizer again, having can
Can there is the situation of burn seedlings, and overfertilization deteriorates can also soil soil property, and the soil that soil property deteriorates not only affects yield,
The agro-farming land area that China is increasingly reduced can also be reduced so that grain drop in production, vicious cycle be formed, additionally, rice terrace has water
This feature, independent rice cultivation is more wasted.The harmful organism such as Scale in Paddy Field Rice Diseases and weeds be restrict rice yield it is important because
Son, in order to mitigate the production loss that weeds and disease pest and weed are caused, substantial amounts of chemical pesticide is used in Rice Production.This is not only
Rice field beneficial organism is killed, ecological balance has been destroyed, the persticide residue in Oryza glutinosa has been increased, cannot get Product Safety
