Abstract

The invention discloses a seedling-stage nutritional addition material stable in fertilizer efficiency and long in action period. The seedling-stage nutritional addition material is prepared from, by weight, 23 to 27 parts of coal slime, 22 to 24 parts of rice chaff ash, 1 to 2 parts of nitrilotriacetic acid, 10 to 14 parts of sodium nitrate, 16 to 18 parts of sawdust, 17 to 19 parts of chicken feather, 6 to 8 parts of fulvic acid calcium, 36 to 40 parts of volcanic rock, 18 to 20 parts of threonine mother liquor, 21 to 25 parts of aged tea, 72 to 78 parts of waste crop straw, 4 to 5 parts of composite fungal hyphae, and an appropriate amount of water. According to a preparation method, the seedling-stage nutritional addition material is prepared from common raw materials such as coal slime and waste chicken feather via a plurality of steps such as fermentation, chelation, and pelletizing, and is capable of improving soil physicochemical properties and nutritional characteristics; a large amount of fungus is added, so that the seedling-stage nutritional addition material is capable of providing seedlings with required nutrients, relatively stable complementary nutritional system among the bacteria is formed; dominant bacterial communities are formed; and activity of the seedling-stage nutritional addition material can be maintained for a relatively long time, and fertilizer efficiency is achieved.

Description

Long seedling stage a kind of fertilizer efficiency stabilization phase is with nutrition addition material and preparation method thereof

Technical field

The present invention relates to a kind of technical field of fertilizers, the seedling stage that particularly a kind of fertilizer efficiency stabilization phase is long is with nutrition addition material and preparation method thereof.

Background technology

Growing of farm crop can be divided into seedling stage, vegetative period and three periods of ripening stage, and its nutritive property refers in the demand percentage of different steps to nutrient, and is directly connected to crop yield height.Seedling stage, the nutritional status in this stage particularly Nitrogen supplying grew important in inhibiting to it, not only has influence on the trophic level of middle latter stage, and determines the final yield level of crop as the need fertile critical porion of crop.

Macro fungi refers to free-hand adopting, the fungi of large-scale sporophore can be produced, it is one of nature Important Decomposers, it can improve rhizosphere environment to infecting of crop, promote that plant is to the absorption of soil nutrient, has synergy between the useful fungi of diversification simultaneously, the common Promoting plant growth of energy, therefore, the mix and match of many fungies is used in aspect of increasing soil fertility and has good application prospect.

Seedling stage due to plant growth, the while of shorter, required nutrient was less, therefore the nutrition addition material on the market for crops seedling stage is little, and it is main based on inorganic fertilizer, life-time service not only causes nutrient imbalance, simultaneously because extremely low utilization ratio result in the pollution of edatope, compromise plant growth and HUMAN HEALTH.For this reason, current inventor provides the nutrition addition material that a kind of crops seedling stage uses, which use a large amount of organic-biological matter, to arrange in pairs or groups multiple fungi effect, a large amount of agricultural wastes can not only be consumed, improve the utilising efficiency of resource, and provide organic nutriment of high-efficiency environment friendly for crops seedling stage, have significant promoter action to the seedling growth of crop and later stage output.

Summary of the invention

The present invention compensate for the deficiencies in the prior art, and the seedling stage providing a kind of fertilizer efficiency stabilization phase long is with nutrition addition material and preparation method thereof.

Technical scheme of the present invention is as follows:

Mulch film of the present invention is made up of the raw material of following weight part: coal slime 23-27, rice chaff ash 22-24, nitrilotriacetic acid(NTA) 1-2, SODIUMNITRATE 10-14, wood sawdust 16-18, chicken feather 17-19, xanthohumic acid calcium 6-8, volcanics 36-40, Threonine mother liquor 18-20, old tea 21-25, discarded crop material 72-78, composite fungi mycelia 4-5, water are appropriate;

Described composite fungi mycelia is bolete mycelia, VA bush mycorrhiza agent, orange mushroom mycelium, white Daedalea mycelia, and proportion is 2:2:1:1.

The concrete steps of the preparation of described nutrition addition material are as follows:

(1) volcanics is mixed with Threonine mother liquor be placed in calcining furnace, at 580-640 DEG C, calcine 1-2 hour, pulverize after taking out and obtain volcanics mineral powder, then mix with the old tea ground, be placed in granulating disc and make particle, for subsequent use;

(2) 3-5 days is tanned by the sun under discarded crop material being placed in sunlight, jointly mixing with coal slime, rice chaff ash, wood sawdust, chicken feather after being cut into the segment of 3-4cm drops in fermentation vat, as adding composite fungi mycelia in fermentation vat, adding suitable quantity of water after stirring keeps fermentation heap water-retaining capacity to be 35%-45%, fermentation 21-25 days;

(3) step 2 gained tunning press dewatering is obtained bacterium slag and fermented liquid, in fermented liquid, add xanthohumic acid calcium and nitrilotriacetic acid(NTA), and regulate PH to neutral, chelating 30-40 minute at 60-65 DEG C, add SODIUMNITRATE after cooling, after stirring, obtain chelating liquid;

(4) stir after step 1 gained particle being mixed with step 3 gained bacterium slag and chelating liquid, then put in whizzer, with 60-80 rev/min of centrifugal 16-18 minute, obtain bag by particle;

(5) bag is sprayed onto by particle exterior surface by after other leftover materials and the centrifugal unnecessary mixing of materials of step 4 with high-pressure spray gun, and air-dry with gas blower at 40-50 DEG C, and weighing and bagging is placed on dry shady and cool place and preserves.

Beneficial effect of the present invention:

In preparation process, the mixed calcining of volcanics and Threonine can fully remove the organic composition wherein contained, and causes secondary pollution, add the specific surface area of mixture simultaneously after preventing entering soil, and its adsorptive power to bacterium slag is strengthened.

The mixing granulation of use old tea and trade waste Threonine mother liquor is the recycling to resource, simultaneously produce acid-soluble effect and complexing action as the low molecular weight organic acid of activator contained by it and tea-polyphenol etc. and the metal ion in volcanics and discharge the nutrient that crop easily absorbs, the carbohydrate simultaneously contained can by the clay minerals active adsorption in soil, thus masking action is lighted to the adsorption potential such as phosphorus, potassium on clay mineral surface, reduce fixing to by the available nutrient that activates in nutrition addition material of soil.

Nutrition addition material of the present invention uses the common raw material such as coal slime, waste material chicken feather, made by multistep operations such as fermentation, chelating, granulations, have improvement soil physico-chemical property and trophicity concurrently, the use of a large amount of fungi simultaneously can not only supply the nutrient needed for seedling, metastable mutual trophic system can also be formed between each bacterial classification, and form dominant microflora, maintain nutrilite and can have activity in a long time thus play fertilizer efficiency.
