Abstract
The invention discloses a method for preparing a compound fertilizer for selenium-poor soil. The method comprises the following steps: (A) crushing monoammonium phosphate, sweet potato seedlings and leguminosae straws until the size is 100-120 meshes for later use; (B) putting decomposed goat manure, crushed eggplant poles, crab shell powder, monoammonium phosphate, a mixture, which is prepared from peat soil and river silt according to the mass ratio of 1: 5, pomegranate peel powder and sweet potato seedlings into a fermentation tank, adding water until the materials are submerged, covering the upside of the fermentation tank with a plastic film, and fermenting for 25-30 days; (C) weighing 1-3 parts of ferment, proportioning to obtain 500-times volumetric concentration, pouring into the fermentation tank, and continuing to close and ferment for 10-12 days until solid ingredients in the proportioned materials are dissolved; (D) adding 3-5 parts of selenium additive into the material obtained in the step (B), uniformly stirring, then, leading out the material, repeatedly overturning with an overturning machine, overturning once every 3-day airing until the moisture content is 45-55%, adding trace elements, uniformly stirring, feeding to an extrusion machine for extruded granulation, so as to obtain granules, and drying, thereby preparing the compound fertilizer for the selenium-poor soil, wherein the selenium additive is sodium selenite. The method disclosed by the invention is simple, the proportioning of the prepared product is simple, the content of selenium in the organic fertilizer is high, the selenium content of the soil can be remarkably increased, and then, the absorption ratio of crops is obviously increased.
Description
Technical field:
The present invention relates to technical field of fertilizers, relate in particular to the manufacture method of a kind of poor selenium soil composite fertilizer.
Background technology:
Selenium is one of trace element of needed by human, it has anti-oxidant and ability that delay senility, but, supplementing of selenium element, selenium element is not to be innately present in food, current rich selenium product is all that crop absorbs the fertilizer of selenium element in process of growth produces by fertilising, and the selenium content relation of the picked-up of selenium and soil exceedes the relation with diet style.The soil of America & Canada contains enough selenium.So, in the food that a lot of crops are made, there is selenium, the selenium content of plant food is decided by the selenium content in local water and soil, for example, the selenium content of the high selenium of China area grain that produces is up to 4 ~ 8 milligrams of per kilograms, and the grain in low selenium area is 0.006 milligram of per kilogram, and the two differs 1000 times.Strengthen rich selenium food exploitation, have important business & economy and be worth, build up people's health especially, at present, southern area rice is low containing selenium, lacks selenium very serious to HUMAN HEALTH prestige association.Most of place, Jiangsu is to lack selenium area, and Qidong liver cancer, Yancheng lung cancer, intestinal cancer and mammary cancer etc. are all relevant with the scarce selenium of local people's meals.So mending selenium is significant for improving people ' s health level.So, in order to make plant absorb enough selenium elements from soil and then to make the food obtaining become rich selenium product, must improve soil, the especially improvement to poor selenium soil, is badly in need of poor selenium soil composite fertilizer.In view of this technical problem, need to occur that a kind of manufacture method is simple, the product proportioning making is simple, and in fertilizer, selenium content is high, can significantly improve soil selenium-containing amount, and then obviously improves the manufacture method of a kind of poor selenium soil composite fertilizer of crop absorption ratio.
Summary of the invention:
The object of the invention is to overcome the shortcoming existing in prior art, provide a kind of manufacture method simple, the product proportioning making is simple, and in fertilizer, selenium content is high, can significantly improve soil selenium-containing amount, and then obviously improve the manufacture method of a kind of poor selenium soil composite fertilizer of crop absorption ratio.
To achieve these goals, the invention provides the manufacture method of a kind of poor selenium soil composite fertilizer, it is characterized in that, comprise the steps:
A, by monoammonium phosphate pulverize, sweet potato vine powder is broken, pulse family class crushed stalk is all crushed to big or small 100-120 order, for subsequent use;
B, by the sheep excrement becoming thoroughly decomposed, eggplant stem crushed material, crab shell powder, monoammonium phosphate, turfy soil and bed-silt be according to the mixture of 1:5 mixture, Pomegranate Rind, ground melon seedling is put in fermentation vat, add water to and do not have material, above capping plastic film, fermentation 25-30 days;
C, go 1-3 part ferment proportioning to 500 times volumetric concentration, be poured in fermentation vat, continue capping fermentation 10-12 days, the solid composition to batching dissolves;
D, material in step B is added to 3-5 part selenium additive, selenium additive is Sodium Selenite, after stirring, derive material, repeatedly turn over throwing with anti-throwing machine, every airing is turned over throwing once in 3 days, while being 45-55%, adds trace element to stir to water content, send into forcing machine and carry out extruding pelletization, the particle obtaining makes poor selenium soil composite fertilizer of poor selenium soil composite fertilizer after drying.
The poor selenium soil of step D gained is 12-18g/ kilogram with the selenium constituent content of composite fertilizer.
The poor selenium making through manufacture method of the present invention composite fertilizer for soil, wherein, comprises the following component of parts by weight:
Sheep excrement 400-500 part of becoming thoroughly decomposed, eggplant stem crushed material 30-50 part, crab shell powder 80-120 part, monoammonium phosphate 50-80 part, turfy soil and bed-silt be according to mixture 40-60 part of 1:5 mixture, Pomegranate Rind 10-30 part, ground melon seedling 80-120 part.
Or, comprise the following component of parts by weight:
Sheep excrement 400-450 part of becoming thoroughly decomposed, eggplant stem crushed material 30-40 part, crab shell powder 80-100 part, monoammonium phosphate 50-70 part, turfy soil and bed-silt be according to mixture 40-50 part of 1:5 mixture, Pomegranate Rind 10-20 part, ground melon seedling 80-100 part.
Or, comprise the following component of parts by weight:
Sheep excrement 450-500 part of becoming thoroughly decomposed, eggplant stem crushed material 40-50 part, crab shell powder 100-120 part, monoammonium phosphate 60-80 part, turfy soil and bed-silt be according to mixture 50-60 part of 1:5 mixture, Pomegranate Rind 20-30 part, ground melon seedling 100-120 part.
