Abstract
The invention provides an organic micro-molecular nitrate-reducing fertilizer. The nitrate-reducing fertilizer is prepared according to a method comprising the following steps: 1) mixing plant cake, animal protein, enzyme microorganism, brown sugar, wheat bran and water, and then fermenting, thereby obtaining fermentation liquor; drying the fermentation liquor, thereby obtaining a fermentation material; 2) concentrating monosodium glutamate tail liquid, and then filtering, thereby obtaining filtrate; and mixing the filtrate with the fermentation material, and then adding carboxymethyl chitosan and polyvinylpyrrolidone, and adjusting and controlling the pH value to be 6-8, thereby obtaining the nitrate-reducing fertilizer. The organic micro-molecular nitrate-reducing fertilizer provided by the invention is directly absorbed by plants, has the characteristic of preferential absorption and is the end product of plant absorbing nitrate. The fertilizer and the adjustment for the activity of nitrate reductase and nitrite reductase are utilized to perform feedback inhibition on the absorption of the nitrate. The organic micro-molecular nitrate-reducing fertilizer has multiple functions of reducing nitrate content in the plants, increasing production, increasing sugar and vitamin, and the like.
Description
Technical field
The present invention relates to a kind of organic fertilizer, be specifically related to a kind of organic molecule and fall nitre fertilizer.
Background technology
In recent years, a large amount of uses of open country and facility vegetable plot nitrogenous fertilizer make the content of vegetable nitrate significantly increase.The inorganic nitrogen of the general direct absorption ammonium nitrogen of vegetables, nitric nitrogen plasma state, when nitrogen fertilizer amount was low, the growth of vegetables was suppressed, and the content of nitric nitrogen also can reduce; Improve nitrogen fertilizer amount, vegetable growth amount and nitrate nitrogen content all can increase.But nitrogen fertilizer amount is too high, and the growth of vegetables also can be suppressed, and living weight shows downward trend, and Nitrate in Vegetable can increase with the increase of amount of nitrogen.The nitrate salt 70%-80% of people picked-up is from vegetables, nitrate salt itself harmless or poison relatively low, but the reducible one-tenth nitrite of nitrate salt of entering human body, nitrite can make adnormal respiration, causes the Digestive tract canceration.Therefore; In order to reduce the nitrate salt of human body Excessive Intake, prevent that it from producing harm to HUMAN HEALTH, many in the world countries all reduce the method for vegetable nitrate under the situation of research in the not underproduction at present; Wherein be to adopt nitrification inhibitor mostly; Slow down the nitrated speed of the ammonium fertilizer that is manured into soil, with the absorption of minimizing vegetables to nitrate salt, but effect is unsatisfactory.Therefore, be necessary to provide a kind of fertilizer, it improves yield and quality when reducing nitrate salts content of vegetable, thereby improves the quality and the safety of agricultural-food.
Summary of the invention
The purpose of this invention is to provide a kind of organic molecule and fall nitre fertilizer.
Nitre fertilizer falls in organic molecule provided by the invention, prepares according to following method:
1) plant cake, zymophyte, brown sugar, wheat bran and water are mixed and ferments obtains fermented liquid; With said fermented liquid through the dry material that must ferment;
2) the monosodium glutamate tail washings must be filtrated through concentrating after-filtration; Said filtrating is mixed the back add CMS and Vinylpyrrolidone polymer with said fermentation material, and regulation and control pH value promptly gets the said nitre fertilizer that falls for 6-8.
Above-mentioned falls in the nitre fertilizer, and the said plant cake of step 1) can be dregs of beans, rapeseed meal or cottonseed meal.
Above-mentioned falls in the nitre fertilizer, and the said zymophyte of step 1) can be genus bacillus, milk-acid bacteria, yeast, photosynthetic bacterium or actinomycetes.
Above-mentioned falls in the nitre fertilizer; The ratio of quality and the number of copies of the said plant cake of step 1), zymophyte, brown sugar, wheat bran and water can be (140-280): (1.2-3.5): 1: (11-13): (6-9), specifically can be 143: 1.2: 1: 12: 6,200: 1.7: 1: 11: 7 or 275: 3.5: 1: 13: 9.
Above-mentioned falls in the nitre fertilizer, and the said fermentation of step 1) is an aerobic fermentation; The pH value of said fermentation can be 6-8, as 6,7 or 8; The temperature of said fermentation can be 45 ℃-75 ℃, as 45 ℃, 50 ℃ or 70 ℃; The cycle of said fermentation can be 100 hours-200 hours, as 100 hours, 110 hours or 200 hours, can stir once in every 10-18 hour, as 10 hours, 12 hours or 18 hours.
Above-mentioned falls in the nitre fertilizer, and the said exsiccant temperature of step 1) can be 55 ℃-75 ℃, as 55 ℃, 60 ℃ or 65 ℃; The said exsiccant time can be 3 hours-7 hours, as 4 hours, 5 hours or 6.5 hours.
Above-mentioned falls in the nitre fertilizer step 2) said spissated multiple can be 0.4-0.5, as 0.4,0.45 or 0.46.
Above-mentioned falls in the nitre fertilizer; Step 2) ratio of quality and the number of copies of said filtrating, fermentation material, CMS and Vinylpyrrolidone polymer can be (1-4): (5-8): (0.1-0.3): (0.1-0.2), and as 2: 5: 0.1: 0.1,4: 8: 0.25: 0.2 or 1: 7.5: 0.2: 0.15.
