Abstract
The invention provides amino acid leaf fertilizer which is composed of 20-50 percent of compound amino acids, 1-50 percent of nicotinic amide, 10-20 percent of green vitriol, 10-20 percent of urea, 5-10 percent of boric acid, 1-5 percent of ascorbic acid and 1-5 percent of surface active agent, namely polysorbate 80. The pH value is required to be 5.0-6.0. The fertilizer efficiency of the amino acid leaf fertilizer is stable, the fertilizer can obviously strengthen the iron nutrient of paddy rice seeds with different genotypes, averagely, the content of iron in winnowed paddy can be obviously increased by above 15 percent, the content of protein and amino acid in the winnowed paddy rice can be obviously increased, the nutrition and the quality of paddy rice can be enhanced all sidedly, the quality is excellent and the cost is low. Therefore, the amino acid leaf fertilizer can be applied in the highly effective biological strengthening of the iron nutrient in paddy seeds and the remarkable promotion of the nutrition and the quality of paddy rice.
Description
Technical field
The invention belongs to the foliar nutrient field, relate to a kind of foliage-spray that is used for specifically, can make the nutrition of rice grain iron obtain high efficiency bio-augmentation, the novel amino foliar nutrient that the rice nutritional quality is significantly improved.
Technical background
The nutrient imbalance problem that iron deficiency causes is present one of human main nutrient health problem that faces in the world.Iron deficiency seriously undermines human immune system's function, hinders health and grows normally.It is reported that surpass the influence that 3,000,000,000 people just are being subjected to iron, zinc nutrition shortage in the world, mainly concentrating on developing country is among the crowd of staple food with rice.In these countries, the school-ager of 40%-45% suffers from anemia, wherein makes an appointment with half owing to iron deficiency causes.The iron nutritional status of population of China allows of no optimist equally.In China especially central and west regions, because of taking in the bad problem ubiquity of human nutrition that iron level is not enough to satisfy the demand and causes in the staple food crop.
On the other hand, along with the raising of people's living standard, and the continuous increase of grain yield, agriculture production is just from being that target changes to the good quality and high output direction with single high yield.Agricultural product quality particularly nutritional quality and health quality comes into one's own day by day.But limited by economic level, China and most of people of developing country are food with vegetable food (mainly being rice, wheat, corn and vegetables) mainly, thus agricultural-food especially vegetable food be the indispensable important source of needed by human nutritive substance and benefit materials.In case when lacking iron, zinc and vitamins and other nutritious components in the product, HUMAN HEALTH will be subjected to direct influence.Therefore, the iron level of raising staple food crop and products thereof is significant to alleviation or the malnutritive problem of elimination human body iron.
Paddy rice is one of important crops in the world, and about 50% population is food with the rice, but rice is low iron, zinc nutrition food, and iron, zinc content on average only have 2mg kg in the polished rice
-1With 12mg kg
-1And the daily intaking amount of iron, zinc recommendation is 10-15mg and 12-15mg.Therefore, improve rice grain and be iron in the rice, zinc content to improving human body iron, zn deficiencie, it is significant to improve the human health level.
The method that is used at present the nutrition of biological reinforced rice iron in the world mainly contains three kinds: plant breeding, improvement of genes and agronomic measures.Crop species by conventional breeding and Plant Biotechnology seed selection and exploitation iron, zinc nutrition heavy duty detergent and kind are one of important method of strengthening iron, zinc content in the vegetable food such as rice grain, and the research of this respect also enjoys various countries' plant breeding scholar and nutritionist's attention.But conventional breeding is consuming time expensive; Biotechnology research is the expense costliness not only, and the Biosafety problem that thereupon produces remains to be inquired into.Moreover these technology all can not in time satisfy body trace element iron, the zn deficiencie problem that needs to be resolved hurrily, and the problem that the effective iron of soil, zinc under long-term planting high ferro, the zinc kind condition are exhausted is not paid close attention yet.Now, by the farming measure, particularly fertilising method of waiting the nutrient comprehensive management technology to improve iron, zinc content in the vegetable food such as crop kernel is considered to a kind of continuable, safe and solution economy.Existing a large amount of test-results show, not only can improve crop yield by fertilising and crop nutrition content integrated management, and can significantly increase and make trace element (as iron, zinc) content in the object, improve the crop alimentary quality.
