Abstract

The invention discloses a rice straw compound fertilizer for improving saline-alkali lands. The compound fertilizer is prepared from the following components in proportioning: 1000 parts of dry straws, 2000 parts of biogas slurry, 250-400 parts of urea, 60-80 parts of monopotassium phosphate, 60-90 parts of boric acid, 80-90 parts of chromium trichloride, 80-100 parts of manganese chloride, 120-140 parts of zinc sulfate, 12-15 parts of Trichodermaspp, 12-20 parts of Aspergillusflavus, and 20-30 parts of Polyangiumcellulosum. The preparation of the compound fertilizer comprises the following steps of: selecting the biogas slurry; implementing aerobic fermentation; implementing anaerobic fermentation; adding boric acid, chromium trichloride, manganese chloride and zinc sulfate in a fermentation tank and evenly mixing to obtain a mixture; and bagging for packaging the mixture.

Description

Alkaline land improving rice straw composite fertilizer

Technical field

The present invention relates to a kind of paddy rice fertilizer, particularly relate to a kind of rice straw composite fertilizer that is applicable to alkaline land improving.

Background technology

Paddy rice is important crops, to the salt stress medium sensitivity, salinity is one of important environmental factors that influences rice growth, is accompanied by the scarcity of process of industrialization and Freshwater resources and the salting of soil that occurs has become current rice cropping needs one of important difficult point of breakthrough badly; Salt damage is the main abiotic stress of restriction Rice Production, and under the salt marsh condition, its output descends, and the salt sensitive varieties is subjected to the influence of salt stress bigger than the salt tolerant kind; Paddy rice is the big crop of fertilizer requirement simultaneously, need fertile about 8,000,000 tons year, account for the disappear 17-20% of fertile amount of China's chemical fertilizer, and long-term list to fertilize, can cause long-acting problems such as soil compaction, nutrient imbalance, physical behavior difference, 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.

Summary of the invention

Technical problem to be solved by this invention provides a kind of specialty of paddy rice cheaply stalk composite fertilizer that is applicable to the environmental protection of salinized soil, the physiology that present method combines the output formation of paddy rice needs fertilizer, takes full advantage of microbiological deterioration stalk formation compost made of stalks and improves paddy rice to the adaptability of salinized soil with rational fertilizer proportioning.

The invention provides alkaline land improving rice straw composite fertilizer in order to overcome the above problems, each component is made by following proportioning:

1000 parts of dry straws, 2000 parts of natural pond liquid, 250～400 parts in urea, 60～80 parts of potassium primary phosphates, 60～90 parts of boric acid, 80～90 parts of chromium trichlorides, 80～100 parts of Manganous chloride tetrahydrates, 120～140 parts in zinc sulfate, 12～15 parts of Trichodermas (Trichodermaspp), 12～20 parts in flavus (Aspergillus flavus), 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 many capsular fiberses bacterium simultaneously, stir, carry out aerobic fermentation, keep the interior temperature of fermentor tank at 45～55 ℃ of fermentation 40d;

The 3rd step: anaerobic fermentation: open fermentor tank and add Trichoderma, flavus 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 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, can significantly improve salting of soil, improve the quality of paddy rice, use the paddy rice 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.
