Abstract

The present invention discloses rice long-lasting special-purpose fertilizer. Rice hull ash is used as a chief constituent, and a plurality of trace elements contained in the rice hull ash are mixed and compounded with citric acid soluble phosphorus, urea, potassium fertilizer, etc. into the rice long-lasting special-purpose fertilizer which is suitable for rice in different growth periods. Field experiments show that the trace elements in the rice long-lasting special-purpose fertilizer can be easily absorbed by rice; the elements do not generate antagonism and can promote each other; the elements can not be fixed easily by soil, and the fertilizer effect can be fully performed and can exist for a long period. Burnt rice hull ash not only contains trace elements but also contains organic elements which are favorable for various crops; rice hull ash has a sterilizing function, and thus, the rice long-lasting special-purpose fertilizer can control and kill various fungi in early spring. The present investment can change the hardening state of soil, can improve water absorbing capacity and can raise ground temperature sufficiently for seedlings to grow; the present investment can prevent low temperature and can improve stress resistance and the yield of rice.

Description

Long-acting rice fertilizer

Technical field

The present invention relates to a kind of paddy rice-dedicated fertilizer material, can be used as paddy rice base manure and field and topdress.

Background technology

Paddy rice is at each growth period, Different Nutrients is absorbed different, therefore, according to paddy rice each vegetative period to the needs of the nutrient rational application of fertilizer by stages, base manure is the basic fertilizer source of paddy rice development growth whole process.In process of growth, as turn green, tiller, also especially need be when educating fringe based on trace element be the promotion plant growth agent and the fertilizer efficiency promotor of assisting with humic acids, zinc sulfate.And for a long time paddy rice anti-blue or green, generally all use ammonium sulfate and urea, this two seed manure to run into water when tillering and high temperature often causes because of the water evaporates fertilizer efficiency and can not give full play to, used easy burning seedling many, red spot disease.

Summary of the invention

The object of the present invention is to provide a kind of strong rice shoot of educating, promote rice tillering and growth, reach good quality and high output green long-acting paddy rice-dedicated fertilizer efficiently.

The applicant was in application rice hull fuel shaper in 2005, application number: 200520021146.0 and rice hull fuel and manufacture method thereof, 2005100135.7 two patents of application number, when producing rice hull fuel, quantity discharged for control titanium dioxide phosphorus, add unslaked lime, make in the rice husk after the burning and contain a certain amount of phosphorus and calcium, K content is 3% in the check rice hull ash, Si content is 0.2%, P content is 0.4%, Ca content is 0.5%, also contain other 10 various trace elements, long-acting rice fertilizer of the present invention is to utilize the various trace elements that contains in the rice hull ash, makes to be fit to the special-purpose fertilizer that the paddy rice different growing stages is used.

Long-acting special fertilizer of the present invention mainly is made up of following materials of weight proportions: with synthetic rice hull ash weight ratio 50-70%, the molten phosphorus 5-20% of Chinese holly, urea 5-20%, potash fertilizer 5-20% forms, its raw material is mixed, promptly through stirring, granulation, oven dry, pack; Described synthetic rice hull ash is that rice hull ash is pulverized, and carries out acid adjustment and handles, and makes pH value reach 5-6, adds the potassium humate that crushes with the 10-20% of the weight of rice hull ash, and stirring makes; The molten phosphorus of described Chinese holly is pulverized the humic acids that accounts for calcium superphosphate weight 5-20%, adds ammoniacal liquor and the zinc sulfate of the concentration of calcium superphosphate weight 1-10% at 3-10% respectively, mixes with calcium superphosphate, stirs promptly to make.

The screening formulation that is used as base manure is: with the rice hull ash weight ratio 50-70% that modulates, the molten phosphorus 5-20% of Chinese holly, urea 5-20% and vitriolate of tartar 5-20%, active organic fertilizer 15-30%, being mixed can make the long-acting base manure of paddy rice of the present invention through stirring, granulation, oven dry, pack.Long-acting rice base manure of the present invention is applicable to rice growing season, and the base manure test and appraisal are than chemical fertilizer volume increase 8-10%.

Being used as the screening formulation that topdresses is: with the rice hull ash weight ratio 50-70% that modulates, the molten phosphorus 5-20% of Chinese holly, urea 5-20%, potassium humate 5-20% and zinc sulfate 1-10%, being mixed to make through stirring, granulation, oven dry, pack that the present invention is long-acting to topdress.Long-acting rice of the present invention topdresses and is applicable to that paddy rice topdresses the phase, and the effect of increasing production of topdressing is at 10-15%.

Long-acting rice fertilizer of the present invention is applicable to paddy growth each period.Described potash fertilizer can be vitriolate of tartar or potassium humate.Long-acting rice fertilizer of the present invention, with the rice hull ash is main raw material, owing to contain various trace elements in the rice hull ash, mix mutually with potassium humate, make trace element can be dissolved in the humic acids, form inner complex, make humic acids become various trace elements and enter the intravital carrier of plant, through these trace elements of field test especially easily by plant absorbing.Not only do not produce antagonism between each element, and can mutually promote, and be difficult for by soil fixing, the effect of fertilizer can be given full play of, and reaches long-acting purpose.Rice hull ash after the burning not only contains trace element, also contains the organic element that helps various farm crop needs, and rice hull ash has sterilizing function, changes soil compaction, improves water-retaining capacity, improves ground temperature, improves resistance.The present invention is a kind of utilization again of waste resource, is a kind of benign cycle of resource.

Embodiment

Long-acting rice fertilizer of the present invention, preparation process:

1, at first rice hull ash is crushed to the 40-60 order, carries out acid adjustment and handle, make pH value reach 5-6, add the potassium humate that crushes, stirred 2 hours, reacted 6 hours at reactor again with the 10-20% of the weight ratio of rice hull ash;

2, the humic acid powder that accounts for calcium superphosphate weight 5-20% is broken to the 40-60 order, add and account for the promotor ammoniacal liquor of calcium superphosphate weight 1-10% concentration at 3-10%, add the neutralizing agent zinc sulfate that accounts for calcium superphosphate weight 1-10%, mix with calcium superphosphate, stirred 2 hours, reactor reaction 1-2 hour, controlled temperature made the molten phosphorus of Chinese holly at 30-100 ℃ again;

3, with horse, ox, pig, chicken manure fermenting, controlled temperature is between 55-65 ℃ during fermentation, and fermentation time was at 5-7 days, and it is standby to form a kind of active organic fertilizer after fermenting;
