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 the resident of about 2/3rds 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., attach great importance to output in China's rice production in the past and ignore the quality of rice, in today that standard of living progressively improves, people are more and more higher to demand balanced in nutrition, make also more and more to pay attention to the nutritional quality of rice in recent years.
Zinc, symbol of element Zn, being 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 plays irreplaceable effect.Having now found that zinc take part in synthesis and the activation of more than 200 kind of enzyme, is the trace element uniquely all existed in six large enzyme systems.Also be the important composition composition of various metals albumen, structural protein and nucleic acid simultaneously, in the synthesis of regulation and control body substance and metabolism, maintain the many aspects such as Stability Analysis of Structures and play an important role.
The zinc recommended intake of being grown up every day is 10 ~ 15mg, 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 also result in the shortage of zinc in rice, and then human body zinc insufficiency of intake may be caused, human body Zinc Nutrition Status is had an impact.According to WHO 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 disease 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 being rich in zinc becomes one of important means of science zinc supplementation.The rich zinc technology of current rice mainly contains following several:
One, " outer addition ", as the patent No. 200910248713.9, joins in cooked rice by zinc element with the form of additive, is about to containing the solution of zinc or pulvis according to certain ratio and rice mixing, then carries out some and process.Though the rice rich in zinc of such making 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 ", dry after namely rice zinc-containing solution being soaked.This method can destroy rice internal structure, affects mouthfeel, and it is expensive to take a lot of work, and should not preserve.
Three, " crop foliar spray method ", namely 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, a large amount of inorganic states to be made in rice residual for fertilizer for spraying on leaf surface and this fertilization mode can increase labour cost, and if the liquid fertilizer of high density control the bad damage etc. that may cause crop blade face.
Four, have a large amount of report for applying the research of zinc fertilizer to soil, but these researchs supplement zinc needed for crop normal growth to the impact of crop under mainly paying close attention to soil zinc deficiency situation, the zinc added is not intended to improve the Zn content in crop.A small amount of report is also paid close attention to and is executed zinc improves effect impact on crop Zn content, but general all poor effect, Zn content in crop only can slightly improve, Guo Jiuxin etc. find that in " nitrogen zinc does the impact on rice yield and seed nitrogen, Zn content mutually " direct application of zinc fertilizer can significantly improve the zinc accumulation volume in rice grain in soil, the graphic analyses provided from the document, in rice grain, Zn content can improve about 12% at most.Execute zinc and can improve nitrogen content and crude protein content in rice grain simultaneously, contribute to the quality improving rice.But in actual production life, particularly more and more pay attention to today of quality of life people, the raising of about 10% also seems not enough.In order to meet this demand, we need to obtain more high zinc content rice.Executing nitrogen in a large number and can improve Zn content in rice described in document, but Russia victory wise man waits in " azophoska is on the impact of rice iron, zinc, copper, manganese, magnesium, calcium contents and output " the middle increase found along with applied nitrogen, and in rice grain, Zn content presents the trend first increasing and reduce afterwards.Hao Hulin etc. have also discovered same trend in " for nitrogen level on the impact of rice strain iron, manganese, copper, Zn content and rice quality " literary composition.Therefore, by improving nitrogen fertilizer amount, significantly to improve the method feasibility of Zn content in rice not high.
Therefore, the technical problem obtaining the rice of the more high zinc content of 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, is 14.6 ~ 40.2mg/kg with the rice Zn content that this method is produced.
