Description
Technical field
The invention belongs to proportion of crop planting field, be specifically related to the special zinc fertilizer of a grow wheat and preparation thereof and the method for the production of rich zinc wheat.
Background technology
Zinc is one of trace element of needed by human, plays an important role in growth in humans's growth course, is often described as " flowers of life " and " source of intelligence " by people.Scientist's research shows, zinc take part in the metabolic process of more than 80 kind of enzyme in human body, especially DNA and RNA polymerase, it participates in the synthesis of nucleic acid protein directly, the Differentiation and proliferation of cell and many metabolism, also has the activation of some enzyme require zinc in human body, and play its active function, therefore, zinc is requisite material in the important physiological processs such as growth in humans grows, reproduction heredity, immune and endocrine system, nerve, body fluid, and scarce zinc can have a negative impact to each system of human body.
The recommended intake of everyone zinc every day of being grown up is 10 ~ 15mg, and pregnancy period and lactating women increase 5mg, children everyone every day of 5 ~ 10mg.In global range, due to the zn deficiencie phenomenon ubiquity that causes of zinc intake deficiency, at present, the whole world about has 40% population to face trace element deficiency, especially the women of developing country poverty-stricken area and children.
The 3 kinds of main policies in the past solving zinc nutrition bad problem were: medicament supplements (Zinc Gluuconate Oral Solution etc. as market is sold), nutrient fortified food is (as the production method of the rich zinc flour of the patent report of CN102106358A, its technique for spraying zinc supplementation agent etc. and in addition mechanical stirring forms in flour) and vary the diet (reduce vegetable food, increase the food such as meat product, sea-food).The nutritional status that medicament supplements improving rapidly nutritive deficiency individuality is very useful, but cost is comparatively large, and people are acceptable poor to it, and on the other hand, its side effect also has to cause the attention of people; Nutrient fortified food also will be increased input usually, and the perception of food and local flavor can be made to change, and be also not easily accepted, equally, the security of nourishing reinforced food also can not be ignored; Varying the diet is overcome underfed most desirable route, but in developing country because the reason such as economic or social is also difficult to realize, even if in developed country, due to reasons such as individual human diet's hobbies, varying the diet neither be all feasible to everyone.Therefore, until in today world wide the mankind take the photograph the malnutritive situation of people and be controlled effectively not yet.
In recent years, a kind of strategy has newly caused the common concern of scientist, and the abundance namely by improving staple food Meso-and micro-nutrients zinc meets the demand of people to micronutrient.By Breeding and cultivation approach, improving the Zn content of crop edible portion, when not changing traditional food, the micronutrient needed for people can be provided by staple food steadily in the long term.Economical, effective, essence can solve the malnutritive problem of developing country's population of dependence staple food existence like this.
Wheat is one of staple food crop of the mankind, and Guo Minghui have studied the Zn content of 17 parts of Shanxi wheat, and its variation range is 21-43mg/kg, and average Zn content is that Guo 29.3mg/kg(is intelligent, 2011); Also point out in the review article of Cao Xinyou that the average content of current wheat zinc is about 30mg/kg, wheat grain Zn content has much room for improvement (Cao Xinyou, 2012); As can be seen here, the Zn content in wheat is totally on the low side, can not meet human body aequum every day, the increase slightly of its Zn content, is that the not enough problem of resident's zinc nutrition of staple food has broad spectrum for solving with wheat.
For the Zn content being improved wheat edible portion by breeding methods, international HarvestPlus plan and its sisters project HarvestPlus-China are using the major objective one of of the content improving trace element zinc as crop breeding, to eliminate " recessive hunger ", be now bred as high zinc content (44mg/kg) new variety of wheat " middle wheat 175 "; The patent of CN100493342C also reports a kind of breeding method of wheat with high iron-zinc content, cultivates the wheat " Qinhei No.1 " of a kind of Zn content 135mg/kg, is 4.1 times of common wheat, occupies in the world first of existing cereal crop.By genetic breeding improvement, cultivate rich zinc wheat breed, being a cause of putting things right once and for all to improving wheat zinc nutrition value, being also the work of a permanence, having vast potential for future development; But it is a long-term systems engineering, and wheat breed has certain regional adaptability, just current progress, apart from also applying early, can not solve zinc nutrition lacking problem to maximum range; But after some time, along with going deep into of research, the discovery of specific gene, utilizing traditional breeding method to cultivate zinc-rich nutrient function wheat will come true.Cultivate rich zinc wheat by transgenic technology and achieve major progress at present, but the biosafety debate of genetically modified food seems forever without final conclusion, applying of transgenic wheat also has many obstacles.
And for improving wheat Zinc Nutrition Status by the rich zinc cultivation technique of wheat, utilize the Common Wheat Varieties of existing popularization, in its growth with growth course, improve nutrient environment, improve wheat zinc nutrition utilization ratio, increase wheat Zn content, the research of this problem is seen in report seldom at present, current main research mostly is executes zinc on the impact of wheat yield or prevent wheat to lack the research of zinc, also there is part to improve the research of crop Zn content by foliage-spray zinc fertilizer simultaneously, the Investigation on intensification of wheat zinc seldom can find, but find from rare several research, this rich zinc approach of wheat or feasible, but wheat Zn content increase rate is also on the low side, generally can not more than 50mg/kg.
