Description
Technical field
The present invention relates to a kind of release and release control fertilizers, more particularly, to a kind of suitable for the same dedicated control of summer corn broadcast of seed manure
Release fertilizer.
Background technique
Background of related of the invention is illustrated below, but these explanations might not constitute it is of the invention existing
Technology.
The progress of domestic release and release control fertilizer industry, China has been developed that a variety of release and release control fertilizers at present, and cost is relatively
It is low, generally 1.2~1.3 times of common fertilizer.Portioned product is mainly used for the crops such as rice, cotton, fruit tree at present, is testing
In achieve preferable effect.There is experimental study in China on the crops such as rice, beet, cotton, as forefathers once use long-term efficiency bicarbonate ammonium
Overfertilization effect test is carried out on the crops such as rice, wheat, cotton, sugarcane, tealeaves, rubber and kelp, the results showed that, in sand soil
On earth and growth period longer crop, the fertilizer efficiency of long-term efficiency bicarbonate ammonium is higher than normal ammonium bicarbonate, and can reduce fertilizer application frequency, effect of increasing production
Obviously.With the reduction of release and release control fertilizer production cost and the increase of yield, release and release control fertilizer answering in all kinds of crop productions extensively
With the inevitable direction for being chemical fertilizer development.
Controlled Release Fertilizer can slow down or control the release of nutrient, and fertilizer efficiency period is long and stablizes, and be able to satisfy corn in entire breeding time pair
The demand of nutrient；Reduce the loss such as elution of fertilizer；Dose and number can be reduced simultaneously, are saved labour, are improved fertilizer
Utilization efficiency improves the yield and quality, and saves agriculture production cost.
Summary of the invention
For the above-mentioned problems in the prior art, the object of the present invention is to provide a kind of suitable for summer corn growth
