CN105481585A - Nutrient additive used in seedling stage for activating soil nutrients and preparing method thereof - Google Patents

Abstract

The invention discloses a nutrient additive used in the seedling stage for activating soil nutrients. The nutrient additive can activate mineral nutrients in seedling culture soil and make seedling roots better absorb nutrient elements, especially mineral elements with poor mobility such as phosphorus, zinc and copper. By adopting four fungi, seedling root length density can be increased and root morphology can be changed through stretching, extension and mycorrhizal colonization, the absorption range and absorption capacity of a root system in the nursery stage are improved, and by adding available nutrients easy to absorb and amino acid chelated state nutrients, sufficient nutrients are provided for growth of crop seedlings.

Description

A kind of seedling stage of activating soil nutrient is with nutrition addition material and preparation method thereof

Technical field

The present invention relates to a kind of technical field of fertilizers, particularly a kind of seedling stage of activating soil nutrient 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, provides a kind of seedling stage of activating soil nutrient 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: zeolite powder 20-24, vinegar grain 16-20, xylose powder 18-20, calcium sulfate 2-4, wormcast 22-28, glycine 3-4, ammonium chloride 7-9, volcanics 39-41, old tea 20-24, discarded crop material 58-62, composite fungi mycelia 4-6, Threonine mother liquor 13-15, 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 550-650 DEG C, calcine 2-3 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) 4-6 days is tanned by the sun under discarded crop material being placed in sunlight, jointly mixing with zeolite powder, wormcast, vinegar grain, xylose powder 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 24-25 days;

(3) step 2 gained tunning press dewatering is obtained bacterium slag and fermented liquid, add calcium sulfate and glycine in fermented liquid, and regulate PH to neutral, at 55-65 DEG C, chelating 30-50 minute, adds ammonium chloride after cooling, obtains chelating liquid after stirring;

(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 20-30 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 35-45 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 can activate mineral nutrient in nursery soil, promote that seedlings root is to the absorption of the poor mineral element such as phosphorus, zinc, copper of nutritive element especially movability, the use of four kinds of fungies is by extending, expanding and mycorhiza dissemination, increase seedling beetroot yield and change Root morphology, increase absorption region and the receptivity of nursery stage root system, coordinate the interpolation easily absorbing available nutrient and chelating amino acids state nutrient, the growth for crops seedling stage provides sufficient nutrient supply.

Specific embodiments

Below in conjunction with following embodiment, the present invention is described in further detail:

The raw material taking following weight (kg) is made: zeolite powder 22, vinegar grain 18, xylose powder 19, calcium sulfate 3, wormcast 25, glycine 3, ammonium chloride 8, volcanics 40, old tea 22, discarded crop material 60, composite fungi mycelia 5, Threonine mother liquor 14, water are appropriate;
