Abstract

The invention discloses a tobacco straw compound fertilizer for slowly releasing drought stress. The tobacco straw compound fertilizer is prepared from the following components in parts by weight: 1000 parts of dry straws, 2500 parts of biogas slurry, 200-300 parts of urea, 50-70 parts of monopotassium phosphate, 80-110 parts of boric acid, 60-80 parts of chromium trichloride, 50-80 parts of manganese chloride, 100-120 parts of zinc sulfate, 16-25 parts of polyaspartic acid, 15-20 parts of trichodermaspp, 9-15 parts of micromonospora and 20-30 parts of polyangium cellulosum. The tobacco straw compound fertilizer is prepared through the following steps of: selecting biogas slurry which can normally generate methane; implementing aerobic fermentation; implementing anaerobic fermentation; adding boric acid, chromium trichloride, manganese chloride, zinc sulfate and polyaspartic acid in a fermentation tank to form a mixture; evenly mixing the mixture; bagging and packaging the mixture.

Description

The tabacco straw composite fertilizer of slowly-releasing drought stress

Technical field

The present invention relates to the fertilizer that grows tobacco, particularly relate to a kind of tabacco straw composite fertilizer of slowly-releasing drought stress.

Background technology

The weather that the tobacco happiness is warm and moistening, whole growing is all very high to the requirement of moisture, and only under the suitable ecological condition of moisture, the vital movement of tobacco can be carried out smoothly; But especially northern cigarette district, the most of cigarette district of China, owing to lack necessary irrigation conditions, annual always have some cigarette districts to grow because of the normal growth that soil drought influences the cigarette strain, causes the yield and quality of tobacco leaf to reduce.

Long-term list can cause long-acting problems such as soil compaction, nutrient imbalance, physical behavior difference to fertilize, and throughput significantly descends, the fertilizer fertilizer efficiency is slower again, the agricultural crop straw of prior art and leaf, weeds etc. take directly to burn down on the farm mostly simultaneously, in order to avoid influence is ploughed; This processing mode, though simple, serious to the damage of the beneficial microorganism in the soil, be unfavorable for the growth of farm crop; In addition, carbon accounts for the overwhelming majority in the stalk, is potassium, silicon, calcium, magnesium, sulphur, phosphorus secondly, and the product after the burning mainly contains CO ₂, CO, SO ₂, NO ₂And N ₂O, these obnoxious flavoures have caused the serious environmental pollution after entering atmosphere; If the field is gone back in these rotten backs of stalk heap, with becoming the fertilizer fertilizing soil of horn of plenty, improves soil property; Microorganism is by being secreted into the outer free cellulose enzyme of born of the same parents, with lytic enzyme mechanism and oxydase mechanisms of degradation Mierocrystalline cellulose to the degraded of stalk cellulose; Utilize microorganism Mierocrystalline cellulose finally can be decomposed into CO ₂And H ₂0, and can produce a large amount of tropinas by the growth of microorganism self, therefore use microbial method to handle stalk, can increase substantially its nutritive value; Poly-aspartic-acid is a kind of polymer of amino acid, and a kind of water-soluble polypeptide is biodegradable, has certain biological activity, its as fertilizer sources synergistic agent, can absorb with enrichment soil in the element favourable to plant-growth, can improve fertilizer utilization ratio.

Summary of the invention

Technical problem to be solved by this invention provides a kind of specialty of tobacco cheaply stalk composite fertilizer of environmental protection of slowly-releasing drought stress, the physiology that present method combines the output formation of tobacco needs fertilizer, takes full advantage of microbiological deterioration stalk formation compost made of stalks and improves the tobacco adaptability short of rain to arid with rational fertilizer proportioning.

In order to overcome the above problems the tabacco straw composite fertilizer that the invention provides the slowly-releasing drought stress, each component is made by following proportioning:

1000 parts of dry straws, 2500 parts of natural pond liquid, 200～300 parts in urea, 50～70 parts of potassium primary phosphates, 80～110 parts of boric acid, 60～80 parts of chromium trichlorides, 50～80 parts of Manganous chloride tetrahydrates, 100～120 parts in zinc sulfate, 16～25 parts of poly-aspartic-acids, 15～20 parts of Trichodermas (Trichodermaspp), 9～15 parts of micromonosporas (Micromonospora), 20～30 parts of many capsular fiberses bacterium (Polyangium cellulosum);

May further comprise the steps:

The first step: selected normal gas producing for use 2 months and above natural pond liquid;

Second step: aerobic fermentation, the dry straw chopping is put into fermentor tank with natural pond liquid, potassium primary phosphate, add micromonospora, many capsular fiberses bacterium simultaneously, stir, carry out aerobic fermentation, keep the interior temperature of fermentor tank at 35～45 ℃ of fermentation 30d;

The 3rd step: anaerobic fermentation: open fermentor tank and add Trichoderma and urea, stir, close fermentor tank and carry out anaerobic fermentation, temperature in preceding 2d keeps fermentor tank is at 45～50 ℃, temperature is increased to 60～75 ℃ in 3d～5d fermentor tank, and 6d～30d keeps the interior temperature of fermentor tank at 50～55 ℃;

The 4th step: temperature is down to and is added boric acid, chromium trichloride, Manganous chloride tetrahydrate, zinc sulfate, poly-aspartic-acid behind the normal temperature and mix the pack packing in the fermentor tank.

Useful effect: the method that the present invention utilizes the microbiological deterioration stalk the to prepare fertilizer stalk that can become thoroughly decomposed fully fast prepares fertilizer, use alkali-hydrolyzable nitrogen in the soil of fertilizer of the present invention preparation, rapid available phosphorus, potassium and organic content are all than direct use stalk with do not use the soil height of fertilizer, the fertilizer of the present invention's preparation is as base manure, poly-aspartic-acid can strengthen plant resistance and then slowly-releasing drought stress, improve the quality of tobacco, use the tobacco of the fertilizer of the present invention's preparation, its aminoacids content can maintain higher level, it is long to have solved traditional straw compost preparation time, function singleness, problems such as the difficult control of quality, prepared a kind of stalk composite fertilizer, meanwhile with stalk, natural pond liquid is turned waste into wealth, take full advantage of, beautified environment.
