Description
Technical field
The invention belongs to technical field of fertilizer production, particularly a kind of selenium-rich amino acid microbial organic fertilizer.
Background technology
Fertilizer can improve soil, improves soil fertility, makes the normal eubiosis of soil restoration, can soil organic matter content be increased, form crumb structure, improve Soil ventilation, water conservation, fertilizer conservation performance, thus be conducive to the growth of crop root, improve and improve plant quality and output.Effectively can improve chemical fertilizer utilization ratio, decomposing pesticide remains, and improves crop and builds matter, negatively produces pollution-free food.Fertilizer can reduce the harm causing agricultural-food to cause human body and birds and beasts because chemical fertilizer application is excessive; On the other hand, inorganic, organic nutrient that fertilizer itself contains directly can provide corps nutrient, are conducive to the absorption of crop and the raising of quality, strengthen the activity of soil enzyme.The activity of Soil Microorganism is the basic source that soil enzyme is formed and accumulates.Soil microorganisms content increases, soil peroxidase, saccharase isoreactivity significantly improves, because enzymatic effect strengthens, accelerate the decomposition of the soil organism and the conversion of mineral nutrients, obtain and favourablely give the absorption of farm crop root system to nutrient, biological organic fertilizer can strengthen the ability of plant disease-resistant insect pest.
Amino acid fertilizer is that containing plant protein, to be raw material production a kind of nuisanceless, without the full stress-strain type efficient green agrochemical product innovation of hormone, noresidue with hair, cotton dregs etc.Amino acid fertilizer is mainly applicable to base on the crops such as flowers, vegetables, fruit tree, tealeaves, tobacco and executes and impose, and can significantly improve crop yield, oil recovery enhancement, reduces farm crop and remains, preserve the ecological environment.Research shows, use amino acid fertilizer to improve fruit quality, amino acid is the fundamental unit of constitutive protein matter, and molecular weight is little, directly can be absorbed by crop; Have repair cell wound, detoxification, fertilizer nutrient supply is slow simultaneously, is beneficial to the accumulation of sugar and nutritive substance; Can improve the heavy and output of fruit, amino acid fertilizer nutrient enriches, balanced and supply growth and development of fruit tree reposefully, strengthens photosynthesis, can meet the demand of fruit tree high yield to nutrient; Improve soil physical and chemical property, in amino acid fertilizer, organotrophy enriches, and organic, humic acids can improve soil, promotes the formation of crumb structure, chessom; Organic nutrient runs off few, is stored in soil, increases soil fertility.
Selenium is the trace element of needed by human.Selenium participates in multiple selenoenzyme and Selenonic protein in synthesized human.Its Glutathione Peroxidase, catalysis hydroperoxide or lipid peroxide change water or various alcohols in vivo, eliminate the biomembranous attack of radical pair, and protection microbial film is from oxidative damage; Selenium participates in forming iodate Tiroidina amino acid and takes off iodine enzyme.Selenium can improve human immunity, promotes the synthesis of lymphocytic propagation and antibody and immunoglobulin (Ig).Selenium has kinds cancers such as colorectal carcinoma, skin carcinoma, liver cancer, mammary cancer and significantly suppresses and the effect of protection, and its mesostate methyl enol in body has stronger antitumour activity.The nutrient substances such as selenium and vitamin-E, garlicin, linolic acid, germanium, zinc have collaborative oxidation resistant effect, increase anti-oxidant activity.Meanwhile, selenium has the effect alleviating and alleviate heavy metal toxicity.
Therefore, selenium-enriched fertilizer is widely applied in fertilizer field in recent years, but does not also find containing amino acid whose selenium-enriched fertilizer.Amino acid simultaneously in existing amino acid fertilizer derives from animal fertilizer in a large number, or animals and plants mixed fertilizer, is not easily absorbed by farm crop rhizome and utilizes, or absorption and utilization ratio not high.In addition, aborning by amino acid and fertilizer or trace element fertilizer or macroelement fertilizer in conjunction with time have passed high temperature process, particularly not considered higher temperature carrier in conjunction with during microbial fertilizer, make amino acid and microorganism in the course of processing, occur a large amount of loss, have a strong impact on quality and the result of use of fertilizer.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned technical problem, there is provided a kind of containing amino acid whose selenium-enriched fertilizer, and only adopt the amino acid of plant material production and avoid high temperature in process of production, and with selenium-rich crops stalk production organic compost and as selenium mineral powder, amino acid and microbe carrier, selenium element, amino acid whose absorption and utilization ratio is improved under can guaranteeing the prerequisite of the quality of amino acid and microorganism like this, improve the surviving rate of microorganism, and then improve the overall qualities of fertilizer.
