Abstract

The invention discloses a selenium-enriched tomato liquid fertilizer which is prepared from the following raw materials in parts by weight: 5-8 parts of potassium nitrate, 4-6 parts of nostoc sphaeroids kutz, 4-7 parts of funaria hygrometrica, 4-6 parts of potassium chloride, 5-7 parts of ammonium bicarbonate, 4-8 parts of urea, 1-3 parts of klockmannite, 3-5 parts of mulberry fruits, 2-3 parts of ground phosphate rock, 3-5 parts of plant ash, and 6-9 parts of auxiliaries. The tomato liquid fertilizer is uniform and free from impurity and is simple to prepare, the contents of nitrogen, phosphorus and potassium as well as medium trace elements can all meet the growth requirement of tomatoes, due to the adding of klockmannite, mulberry fruit, nostoc sphaeroids kutz and other raw materials, the content of selenium in the fertilizer can be greatly increased, and crushed funaria hygrometrica contains promoters such as kinetin and benzpyrole-3-acetic acid capable of promoting tomatoes to absorb nutrients and grow, and thus the fertilizer is a tomato liquid fertilizer with a remarkable effect.

Description

A kind of rich selenium tomato liquid fertilizer and preparation method thereof

Technical field

The present invention relates to a kind of technical field of fertilizers, particularly one rich selenium tomato liquid fertilizer and preparation method thereof.

Background technology

Selenium element is the trace mineral nutrient substance of needed by human, owing to there is no the organ of Long-term Storage selenium in human body, selenium needed for body needs constantly to obtain from diet, and the physiological function of balance to many organs, tissue of selenium concentration has important provide protection and promoter action, therefore, various selenium-enriched food is gradually known by people, wherein Se-rich farm products is due to its natural sex and convenience, become the first-selected product mending selenium, but selenium-rich crops is planted in the high place of Selenium in Soils content mostly, region restriction is comparatively serious, and China's overwhelming majority area is all in scarce selenium area, therefore cannot be economical and practical obtain selenium-rich crops, the present inventor designs selenium-enriched liquid fertilizer for this reason, can effectively solve the problem, high by content, the selenium-enriched liquid fertilizer of easy absorption, plantation obtains Se-rich farm products, realize the object of human body being supplemented to appropriate selenium.

Summary of the invention

The present invention compensate for the deficiencies in the prior art, provides a kind of rich selenium tomato liquid fertilizer and preparation method thereof.

Technical scheme of the present invention is as follows:

Fertilizer of the present invention is made up of the raw material of following weight part: saltpetre 5-8, Nostoc 4-6, Herba Funariae Hygrometricae 4-7, Repone K 4-6, bicarbonate of ammonia 5-7, urea 4-8, chalcomenite powder 1-3, Fructus Mori 3-5, ground phosphate rock 2-3, plant ash 3-5, auxiliary agent 6-9;

Described auxiliary agent is made up of the raw material of following weight part: dried small shrimp 8-10, konjaku powder 4-6, Sodium Selenite 2-3, maize spike stalk 24-30, water shield tender stem 6-8, pluck 15-25, yeast rich in selenium 3-4, JT composite fungus agent 2-3, EDTA chelated iron preparation 3-5, EDTA chelated zinc preparation 3-5, EDTA chelating calcium preparation 3-5, EDTA chelated magnesium preparation 3-5, the former powder 5-7 of xanthohumic acid; Its preparation method is placed in fermentation vat by mixing with dried small shrimp, pluck, yeast rich in selenium, JT composite fungus agent after maize spike stalk chopping, at ferment under aerobic conditions 6-10 days, konjaku powder, the tender stem of water shield is added again afterwards in fermentation vat, by the turning of mixed fermentation material once afterwards with on duck cover, anaerobic fermentation 14-20 days, period keeps fermentation heap temperature to be 45-55 DEG C, moisture content 40%-50%, the rear squeezing fermentation heap that fermented obtains fermented liquid, leaves standstill and filters to obtain fermentation clear liquid after 6-10 hour; Again by EDTA chelated iron preparation, EDTA chelated zinc preparation, EDTA chelating calcium preparation, EDTA chelated magnesium preparation, Sodium Selenite, the former powder mixing of xanthohumic acid, and add mixture quality 240-320 water doubly, at the uniform velocity be stirred to whole dissolving, obtain nutritive medium, fermentation clear liquid is mixed with nutritive medium, stirs 10-15 minute.

The concrete steps of the preparation of described fertilizer are as follows:

(1) fragmentation after Fructus Mori, Nostoc, Herba Funariae Hygrometricae being mixed also is ground, and obtains mixing filtrate after filtration, for subsequent use;

(2) by saltpetre, Repone K, bicarbonate of ammonia, urea mixing, add mixture quality 250-350 water doubly, at the uniform velocity stir 30-50 minute, filter to obtain solution 1;

(3) soak 24-36 hour by joining in the water of 200-400 times of quality after ground phosphate rock, plant ash, the mixing of chalcomenite powder, period keeps water temperature at 50-70 DEG C, filters to obtain solution 2 afterwards;

(4) filtrate, solution 1, solution 2, auxiliary agent and leftover materials mixing will be mixed, stir after 15-30 minute and filter, obtain liquid fertilizer.

Beneficial effect of the present invention:

The even inclusion-free of tomato liquid fertilizer of the present invention, preparation is simple, N P and K and medium trace element content all meet needed for tomato growth, the interpolation of the raw materials such as chalcomenite powder, Fructus Mori, Nostoc considerably increases the selenium content in fertilizer, Herba Funariae Hygrometricae fragmentation is afterwards containing promoting that tomato absorbs the promotive factor of nutrient and growth, as kinetin and indole-3-acetic acid etc., it is a kind of tomato liquid fertilizer of Be very effective.

The interpolation of auxiliary agent serves the supplementary effect of nutritive element to fertilizer, and the beneficial microorganism simultaneously comprised in auxiliary agent can improve the quality of soil, the final yield and quality improving crop.
