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 paddy rice and preparation thereof and the method for the production of rice rich in zinc.
Background technology
There is about 2/3rds resident in China using rice as staple food, and as one of most important food crop of China, the cultivated area of paddy rice accounts for the half of China's plant of grain crops area, and distributed areas are vast.Based on population pressure etc., in China's rice production in the past, attach great importance to output and ignored the quality of rice, the today of progressively improving in standard of living, people are more and more higher to demand balanced in nutrition, make in recent years the nutritional quality of rice also more and more to be paid attention to.
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, find through investigation, the situation that China's rice soil lacks zinc is very general, especially the calcareous Paddy Soils of the north and two sides, the middle and lower reach of Yangtze River, this has also caused the shortage of zinc in rice, and then may cause human body zinc insufficiency of intake, human body Zinc Nutrition Status is exerted an influence.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.
Rice is one of staple food grain of China resident, and the edible rice that is rich in zinc becomes one of important means of science zinc supplementation.The rich zinc technology of rice mainly contains following several at present:
One, " outer addition ", as the patent No. 200910248713.9, joins in cooked rice with the form of additive by zinc element, is about to mix according to certain ratio and rice containing the solution of zinc or pulvis, then carries out some and process.Though the rice rich in zinc of making like this has certain effect, but people can wash before edible rice, are commonly called as rice washing, and the actual effect that this process will cause the loss of a large amount of zinc to play is very limited.
Two, " inside enforce the law ", after rice being soaked with zinc-containing solution, dry.This method can be destroyed rice internal structure, affects mouthfeel, and it is expensive to take a lot of work, and should not preserve.
Three, " crop foliar spray method ", in tillering phase of paddy rice, boot stage, filling stage to foliage-spray zinc fertilizer, make its Foliage Absorption, be converted into rice rich in zinc, as the patent No. 200410084878.4 and 200610086308.8.Although this method is more advanced, fertilizer for spraying on leaf surface can make in rice the residual and this fertilization mode of a large amount of inorganic states can increase labour cost, and if the liquid fertilizer of high density control the bad damage that may cause crop blade face etc.
Four, have a large amount of reports for the research that applies zinc fertilizer to soil, but these researchs mainly pay close attention in soil zinc deficiency situation and to supplement the impact of the required zinc of crop normal growth on crop, the zinc adding is not intended to improve the zinc content in crop.A small amount of report is also paid close attention to and is executed the impact of zinc on crop zinc content raising effect, but general poor effect all, zinc content in crop only can slightly improve, Guo Jiuxin etc. find that direct application of zinc fertilizer can significantly improve the zinc accumulation volume in rice grain in soil in " nitrogen zinc is done mutually the impact on rice yield and seed nitrogen, zinc content ", the graphic analyses providing from the document, in rice grain, zinc content can improve at most approximately 12%.Execute zinc and can improve nitrogen content and crude protein content in rice grain, contribute to improve the quality of rice simultaneously.But in actual production life, particularly more and more pay attention to today of quality of life people, it is not enough that the raising of 10% left and right also seems.In order to meet this demand, we need to obtain more high zinc content rice.Executing in a large number nitrogen and can improve zinc content in rice described in document, but Russia victory wise man waits in " impact of azophoska on rice iron, zinc, copper, manganese, magnesium, calcium contents and output " discovery along with the increase of applied nitrogen, in rice grain, zinc content presents and first increases the trend reducing afterwards.Hao Hulin etc. have also found same trend in " impact for nitrogen level on rice strain iron, manganese, copper, zinc content and rice quality " literary composition.Therefore, by improving nitrogen fertilizer amount, significantly to improve the method feasibility of zinc content in rice not high.
Therefore, the technical problem of the rice of the more high zinc content of acquisition high security has to be solved.
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 paddy rice and preparation thereof and the method for the production of rice rich in zinc, with the rice zinc content that this method is produced be 14.6 ~ 40.2 mg/kg.
