Abstract
The invention provides a humic acid-silicon-selenium fertilizer and a preparation technology thereof. The fertilizer is prepared from 50-70wt% of humic acid, 3-15wt% of sodium selenite and 10-30wt% of silicon micro-powder. The humic acid is ammonium humate, or potassium humate, or sodium humate. The humic acid-silicon-selenium fertilizer can be widely used in wheat, corn, soybean, fruits, vegetables and other crops, and has substantial soil improvement, soil solution acidity adjustment, chemical fertilizer fertility enhancement and fertilization cost reduction effects.
Description
Technical field
The invention belongs to field of agricultural fertilizer, a kind of humic acid silicon selenium fertilizer and preparation technology thereof.
Background technology
Along with the high speed development of chemical industry, production and the amount of application of various fertilizer constantly increase, and serve important pushing effect to the development of agriculture production.But along with the continuous increase of applying quantity of chemical fertilizer, it is used shortcoming and also day by day shows especially out, be mainly manifested in following three aspects: 1, be that the fertilising cost that the low output of high investment causes increases.At present, the utilization rate of nitrogen fertilizer in China's chemical fertilizer field is only 15-40%, and phosphate fertilizer utilization efficiency is only 10-20%, and potassium utilization rate is only 20-50%.2, be that green environmental protection is poor, cause soil compaction serious.Soil fertility be the mankind depend on for existence basic, maintaining and increasing soil fertility also is that agricultural could one of the key issue of sustainable development.Excessively use chemical fertilizer, the reason Yi character of soil can be worsened, blocking soil pores, spoiled soil crumb structure, cause soil nutrient elements unbalance, harden, pollute and fertility decline.Excessive chemical fertilizer of using also can cause groundwater pollution and topsoil simultaneously, is also a kind of threat to HUMAN HEALTH.3, be that crop quality is low, directly threaten human life's safety.Current people generally reflect that fruit is not fragrant, melon is sweetless, dish is tasteless, face is not smart, meat is not fresh, and these are all caused by unreasonable fertilising.What the pollution of chemical fertilizer to agricultural-food was the most prominent is that vegetable and fruit nitrite exceeds standard.General vegetables (especially leaf vegetables) are edible cauline leaf mainly, and the timed interval eaten from applying fertilizer to is shorter, and the nitrogen of Crop exists to not changing into protein in time with nitrite form, causes Nitrite Content in Vegetables content very high.Nitrite can be combined with blood in human body in Lactoferrin and form methemoglobin, makes it lose band oxygen ability, causes patient to occur hypoxic conditions, even can make people's death by suffocation time serious.Meanwhile, it is also the major cause causing human carcinomas, cardio-cerebrovascular diseases that excessive nitrite is taken in.
Therefore, how to improve utilization rate of fertilizer, improve soil fertility, strengthen crop quality and become the focal issue paid close attention in world wide.
Summary of the invention
The invention provides a kind of humic acid silicon selenium fertilizer, this fertilizer is widely used in the various crops such as wheat, corn, soybean, melon and fruit, vegetables, Be very effective.
Technical scheme of the present invention is to provide a kind of humic acid silicon selenium fertilizer, it is characterized in that: it is made up of the raw material of following weight per-cent: humic acids 50%-70%; Sodium Selenite 3%-15%: silicon powder 10%-30%.
Described humic acids is ammonium humate, or potassium humate, or Sodium salts humic acids.
The preparation process of described humic acid fertilizer is as follows:
Feed coal is pulverized, at 10 ~ 20 DEG C, the ratio being 7:l in the ammonia source weight ratio of humic acids content and direct ammonification in feed coal in reaction tank adds the ammonia source of feed coal and direct ammonification: nitrogen ammonia, ammoniacal liquor, carbonated aqueous ammonia, or the sodium carbonate added in proportion, or salt of wormwood, stir, and control temperature is at 30 ~ 50 DEG C; In 0.3 hour reaction times, after reaction, resultant is placed 16 ~ 150 hours; Stir granulating, the reactant after granulating to be placed in stoving oven and to dry at 40 ~ 50 DEG C, obtain ammonium humate or Sodium salts humic acids or potassium humate, the Sodium Selenite of the humic acids product made and aforementioned proportion or silicon powder are mixed, gets product.
Feature of the present invention is: in order to effectively improve soil, increase the content that sod regulates the trace element of the soil solution, humic acid fertilizer provided by the invention, the basis of ammonium humate or Sodium salts humic acids or Potassium humate fertilizer adds silicon powder again or is oxidized sub-selenium and mixes with it, after it is manured into soil, the utilization ratio of fertilizer can be improved I5-25%, and the farm crop of revolving fertile rear plantation can be made to contain the trace element of needed by human body, have antitumous effect, it has good economic worth and application prospect widely.The present invention adopts ecosystem material, suitably micro-by the interpolation of science, the humic acid silicon selenium utilizing the kinds of processes such as biological activity, chemical combination, absorption, integration to develop is fertile, complementation can be realized in fertilizer efficiency with chemical fertilizer, utilization rate of fertilizer can be significantly improved, improve Soil structure, strengthen soil fertility.This product can realize the slow releasing of nitrogen chemical product simultaneously, as nitrogen pyrrole quinoline, dihydro-amine etc., thus significantly reduces Nitrate in Vegetable, improves its quality.The green organic products of ecological environmental protection nuisance free as fertile in, humic acid silicon selenium, noresidue can be seen.
Below in conjunction with embodiment, the present invention will be further described.
