Description
Technical field
The invention belongs to proportion of crop planting field, be specifically related to the zinc-rich nutrient agent of a kind of corn and preparation thereof and the method for the production of rich zinc corn.
Background technology
Zinc, symbol of element Zn, is the 4th common metal, is also one of micronutrient element of needed by human, and in human body, its content is only second to iron, and it maintains normal physiological function to human body and is bringing into play irreplaceable effect.Having now found that zinc has participated in the synthetic of 200 plurality of enzymes and activated, is unique trace element all existing in six large enzymes are.Also be the important composition composition of various metals albumen, structural protein and nucleic acid, at regulation and control body material, synthetic and metabolism, maintains the many aspects such as Stability Analysis of Structures and plays an important role simultaneously.
The zinc recommended intake of per day for adults is 10 ~ 15 mg, finds through investigation, and the situation of China's soil zinc deficiency is very general, the especially north and the calcareous soil of two sides, the middle and lower reach of Yangtze River, and this may make the deficiency of zinc content in the crop of China.According to World Health Organization's report, zn deficiencie has become the fifth-largest threat of developing country's residents ' health situation.Zn deficiencie may cause growing fall behind, the generation of a series of diseases such as Development in Puberty is slow, abnormal labor, tetter, illness in eye, immunocyte decline, therefore, science zinc supplementation is extremely urgent.
Corn is important food crop and important feed resource, is also the highest food crop of whole world ultimate production.Be one of three large staple food grains of China, the in all parts of the country eating method that has various corns, comprises directly and boils, fries corn kernel, be processed into Semen Maydis powder punching food or add etc. as coarse food grain.Corn is simultaneously also as the important component of feed.So reaching the object of zinc supplementation by edible corn or corn product is feasible.
Yang Lihua etc. find that in " executing the impact of zinc on corn NPK fertilizers utilization ratio, output and grain quality " executing zinc can improve the utilization ratio of corn to nitrogenous fertilizer and potash fertilizer, can improve output and the grain quality of corn simultaneously.Can find out in the work of " aftereffect of zinc fertilizer to crop yield, seed zinc and Available Zn content in soil " from Wang Hong etc., corn kernel is the potentiality with enrichment zinc, but result can be found out from literary composition, and the method effect is also not obvious.We need to find a kind of method that can produce rich zinc corn, obtain the corn of the more high zinc content of high security.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides the zinc-rich nutrient agent of a kind of corn and preparation thereof and the method for the production of rich zinc corn.With this method produce corn zinc content can reach 15.7 ~ 30.5 mg/kg.

1) by stand-by to zinc source, biological organic fertilizer and acidity regulator grinds powder;
2) according to described amount, zinc source, biological organic fertilizer and acidity regulator are mixed;
3) by step 2) described in mixture granulation on disk, when granulation, add the fertilizer binding agent of described amount, gained fertiliser granulates is corn zinc-rich nutrient agent.
The invention provides the method for above-mentioned corn zinc-rich nutrient agent for the production of rich zinc corn, comprise the steps:
1) when applying base manure again when corn planting, apply the zinc-rich nutrient agent of described corn, described corn is counted 0.25 ~ 16kg/ mu by the applied amount of zinc-rich nutrient agent with the weight of zinc;
2) carry out water and fertilizer management, finally gather in the crops rich zinc corn.
Preferably, in step 1), corn is to count 8 ~ 16kg/ mu with the weight of zinc by the applied amount of zinc-rich nutrient agent.
The invention provides the method for above-mentioned corn zinc-rich nutrient agent for the production of rich zinc corn, comprise the steps:
1) after corn planting, to tasseling stage, apply the zinc-rich nutrient agent of described corn, described corn is counted 0.25 ~ 16kg/ mu by the applied amount of zinc-rich nutrient agent with the weight of zinc;
2) carry out water and fertilizer management, finally gather in the crops rich zinc corn.
Preferably, in step 1), corn is to count 1 ~ 8 kg/ mu with the weight of zinc by the applied amount of zinc-rich nutrient agent, preferably 4 ~ 8 kg/ mus.
The invention has the advantages that:
1, the corn zinc content of producing according to method provided by the invention can reach 15.7 ~ 30.5 mg/kg, is more than the twice of conventional corn zinc content.
2, the corn of producing according to the inventive method meets the requirement of state food standard, has kept the original nutrition of corn to reach again the object of rich zinc, has good physiologically active, is easy to digest and assimilate.
3, there is good controllability, can be according to the corn of different demand production Different Zinc content.
