Abstract

The present invention discloses a crop nitrogen absorption amount improving nutritional additional material in the nursery stage. The nitrogen absorption amount needed in the crop seedling growth largely determines the growth level of crops in the late period. The nutritional additional material uses sawdust, straws, cotton seed hulls and other readily available nitrogen-rich farm waste materials as raw materials. The fermented rotten materials have a large number of crop growth needed nitrogen, phosphorus and other elements, at the same time promote the activities of fungal hyphae in seedling roots, increase the crop absorption area, transfer the fixed nitrogen into young seedling bodies via hyphal links, significantly increase the absorption and utilization of nitrogen in seedling bodies, and have a beneficial effect for the coordination of growth of the crops in the late stage.

Description

A kind of nutrition addition material improving crop seedling phase absorbing nitrogen amount and preparation method thereof

Technical field

The present invention relates to a kind of technical field of fertilizers, particularly a kind of nutrition addition material improving crop seedling phase absorbing nitrogen amount 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, provides a kind of nutrition addition material improving crop seedling phase absorbing nitrogen amount 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: paulownia sawdust 22-24, Sodium hexametaphosphate 99 9-10, leaf-humidified soil 16-22, soybean cake powder 19-21, calcium chloride 4-5, cotton seed hulls 24-26, Whitfield's ointment 1-2, urea 11-13, old tea 20-24, volcanics 39-41, discarded crop material 55-65, Threonine mother liquor 13-15, composite fungi mycelia 6-7, 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 570-630 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) 4-5 days is tanned by the sun under discarded crop material being placed in sunlight, jointly mixing with paulownia sawdust, leaf-humidified soil, soybean cake powder, cotton seed hulls 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 40%-45%, fermentation 18-22 days;

(3) step 2 gained tunning press dewatering is obtained bacterium slag and fermented liquid, in fermented liquid, add calcium chloride and Whitfield's ointment, and regulate PH to neutral, chelating 25-35 minute at 65-70 DEG C, add Sodium hexametaphosphate 99 and urea 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 65-75 rev/min of centrifugal 18-22 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 45-55 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.

Because crops seedling stage grows the level of growth absorbed dose of nitrogen being determined to a great extent to the crop later stage, therefore nutrition addition material of the present invention uses the Fu Dan farmers' dead meals that are easy to get such as sawdust, stalk, cotton seed hulls as raw material, ferment the material that becomes thoroughly decomposed not only has the elements such as the nitrogen phosphorus needed for a large amount of plant growth, facilitate the activity of hypha,hyphae in seedlings root simultaneously, add Crop area, and by Hyphal links by fixing nitrogen translocation in seedling body, remarkable increase seedling absorbing nitrogen, has advantageous effect to coordination crop late growing stage.
