Description
Technical field
The present invention relates to large area field of agricultural production technologies, a kind of jade for maize culture is related generally to
Rice formula fertilizer special.
Background technology
Corn is one of most important cereal crops of China, and the annual maize sown area of China is 36,900,000 public
Hectare, yield reaches 2.1 hundred million tons, and one of Three major grain crops are all with corn and wheat, and its yield occupies China
The 1/3 of grain yield.Corn has extremely important economic worth and social value, and its planting range is covered
China's major part territory, because its is wide in variety, growth period is moderate, is suitable for mountain area, plateau and Plain etc.
Different regions are planted, and are one of staple crops of China's most area.Global corn is produced according to statistics
Amount reaches 9.6 hundred million tons, and the wherein corn yield in the U.S. is 3.4 hundred million tons, accounts for the world more than 30%.China is
Second-biggest-in-the-world Maize Production state, accounts for 20% of Gross World Product or so.In recent years, peasant household is in order to pursue corn
Yield and economic benefit, in maize planting, the usage amount of chemical fertilizer increases year by year, and the chemical fertilizer of most of peasant households is used
It is 60~90kg/ mus to measure, and wherein nitrogenous fertilizer occupies maximum ratio.Because each peasant household is the warp according to oneself
Test using various chemical fertilizer, fertilizer application frequency is more, wasting manpower and material resources, and cannot be standardized or be standardized
Fertilizing management.The purity nitrogen consumption of most of peasant household reaches more than 15 kgs/acre according to statistics.Although in soil fertilizer
The yield of increase corn when power is relatively low with dose also can be improved accordingly, but be excessively used chemical fertilizer not only
Yield does not reach maximization, the problems such as can cause corn yield and quality decline on the contrary.Particularly cultivating
Easily trigger pest and disease damage in journey, finally production cost can only not only increased by preventing and treating of constantly spraying insecticide,
It is also easy to cause residues of pesticides.Additionally, the nitrogenous fertilizer being excessively used can not all be absorbed by corn, remainder
It is converted into ammonium nitrogen or nitrate nitrogen is evaporated in air and turns into one of element for triggering haze aerosol.
Therefore, applicant according to corn grow characteristic and nutritional physiology parameter designing go out it is a kind of suitable
Together in the formula fertilizer special of corn normal growth development, while high yield is ensured, the utilization rate of fertilizer is improved,
The discharge of ammonia nitrogen and phosphorus is reduced, the disease resistance of corn is improved, Pesticide use amount is reduced, the quality of corn is improved
With mouthfeel, recover the original local flavor of corn variety, while improving the nutritive value of corn.
