Description
Technical field
The invention belongs to corn breeding techniques field, more particularly to a kind of fertilizer of corn breeding, preparation method and
Using.
Background technique
Corn (Classification system：Zea mays L.) it is grass family Zea annual herb plant, alias：Maize, stick
Son, maize, corn, corn, maize, maize, maize, luxuriant reed, big sorgo.Corn belongs to annual monoecism cross-pollination
Plant, stalk is upright, and usually branch, base portion do not save the raw prop root of tool gas respectively.Leaf sheath has transverse vein；Tip of a leaf film quality, the flat width of blade
Greatly, wire lanceolar, basal circular are in ear, and hairless or tool defect pubescence, middle arteries are sturdy.Caryopsis spherical shape or oblate spheroid, after mature
Expose except lepicena and bran piece, size generates difference with growth conditions difference.The different flower of monoecism, flowering fruit bearing stage autumn.
Corn was at cultivation history about more than 470 years of China, and China's sown area is only second at 300,000,000 mu or so at present
Paddy and wheat occupies third position in cereal crops, is only second to the U.S. in the world.The whole world torrid zone and Temperate Region in China have extensive kind
It plants, is an important cereal.Corn taste is fragrant and sweet, can do various dish, such as corn irons, corn juice, it be also industrial alcohol and
The primary raw material of liquor.In addition to being important in the world cereal crops and feed, corn is also a kind of important raw material of industry.From
After 1998, global corn yield and cultivated area occupy the 1st, and in cereal crops volume increase total value, corn yield increasing is accounted for
40.5 ‰, it is much higher than wheat and rice.World's corn gross area reached 1.576 hundred million hectares in 2009, yield total 794,060,000
Ton.National 5.24 hundred million mu of maize sown area in 2012.China has become the second largest maize production big country for being only second to the U.S..
In national economy and people's lives, the status of corn is more and more important.
With the fast development of industrial production and animal husbandry level, the demand of corn is significantly increased, the breeding research of corn
Just it is particularly important.Corn breeding production top priority be improve corn yield, improving quality, excavate kind in life
Produce potentiality.To the year two thousand thirty, corn estimated output at least increases by 30% or so.Chemical fertilizer is directly to participate in agricultural production or coordinate to make
The main nutrient elements source of object Nutrition and Metabolism, and it is closely related with the quality and yield of crop.In the planting process of corn
Need to apply chemical fertilizer, however the evolutionary process for changing soil that the use of chemical fertilizer is artificial, so that in existing agricultural production process,
The minerals of nature weathering are unable to satisfy the needs of corn fast-growth, lead to nutrient dificiency, need to carry out artificially to assist adding
Add.However up to 17 kinds of demand of the corn to nutrient, including carbon, hydrogen, oxygen；Nitrogen, phosphorus, potassium；Calcium, magnesium, sulphur etc., and different cultivars
Demand of the corn to nutrient be also different.N P and K is the most common fertilizer element of corn, and reasonable employment nitrogenous fertilizer is to improve
Corn yield, the important measures for controlling leaf presenility.The excessive or very few growth and development that can all influence corn of nitrogen fertilizer amount and
Yield.The study found that it is serious in corn nitrogen hunger or excessive maize leaf early ageing, delay a weight of maize leaf aging nitrogen
Wanting measure is exactly rationally to apply nitrogen.The case where unreasonable application of nitrogenous fertilizer, is more and more in recent years, dosage it is excessive or it is insufficient all
It is unbalanced to will cause soil nitrogen supply.Phosphorus element is participated in as nutrient necessary to corn growth with number of ways
Make the various metabolic processes of object.Studies have shown that, Ke Yiwei different according to absorbability of the different corn varieties to soil phophorus
The efficient corn variety of our breeding phosphorus elements provides genetic potential.Application of potash fertilizer can increase corn yield and yield traits,
But amount of application excessively will cause the underproduction, and suitable potash fertilizer can accelerate the photochemically reactive speed of corn；Promote photophosphorylation
Effect, is conducive to the formation of ATP；Promote the formation of chlorophyll and the absorption to carbon dioxide, and then enhances photosynthetic used, raising
The efficiency of light energy utilization, reaches effect of increasing production.
Main problem existing for fertilising link during corn planting is mainly reflected in：Blindly fertilising phenomenon is serious, supports
Divide and put into imbalance, utilization rate of fertilizer is low, and blindly fertilising phenomenon is generally existing by peasant, is mainly accustomed to and fertilizer market according to former years
Price is applied fertilizer.The habits fertilization mode of urea is matched always in some areas using diammonium for many years, some regional nitrogen, phosphorus dosage are inclined
Height ignores the use of potash fertilizer and micro- fertilizer.Meanwhile fertilizing method is unreasonable, fertilizing equipment does not match, and N-dressed deeply technology does not obtain
To being widely applied.Nitrogen, phosphorus, potassium ratio are unreasonable, cause soil nutrient unbalance, and soil fertility decline, utilization rate of fertilizer is not high, investment
Increase, benefit reduces, and influences the raising of corn yield and quality.At the same time, it is more and more brighter to lack symptom for middle and trace element
It is aobvious, universal zinc-deficiency is shown as, boron deficiency, sulphur symptom occur in some areas.In addition, fertilizer market single variety, quality is irregular,
Managerial confusion；Agricultural workforce's schooling is not generally high, and there is also very big blindness in fertilising；Agricultural technology spread department base
Infrastructure is weak, means fall behind etc., affects the development for the work that applies fertilizers scientifically.
Therefore, research and develop it is a kind of for corn planting, the comprehensive fertilizer of nutrition, especially specifically for corn breeding
Fertilizer be particularly important.
