Abstract
The invention relates to a biological compound fertilizer capable of promoting growth of crop roots. The biological compound fertilizer is prepared from the following components in parts by weight: 20-40 parts of inorganic composition, 30-50 parts of organic composition, 4-8 parts of composite bacterial powder, 5-10 parts of potassium fulvate, 10-20 parts of ammonium calcium nitrate, 5-15 parts of mannitol, and 5-10 parts of bentonite, wherein the composite bacterial powder is composed of Bacillus subtilis, Bacillus licheniformis, Bacillus laterosporus, photosynthetic bacteria and actinomyces. According to the biological compound fertilizer, based on the mutual action principle of plant-microorganism-soil and active response principle of roots to environment, two aspects of rhizospheric microorganisms and fertilizer nutrients are taken as points of penetration, on the basis of meeting the nitrogen, phosphorus and potassium nutrients needed by crops, the air permeability of the soil is regulated by organic matters, the effective absorption of calcium is promoted by chelating calcium ions with mannitol and potassium fulvate, and meanwhile fully water-soluble potassium fulvate has the function of regulating plant growth, so that extended growth of the crop roots and generation of fibrous roots are stimulated so as to finally achieve the effects of promoting growth and development of the plants and improving the yield.
Description
Technical field
The present invention relates to biologic compound fertilizer, specifically, relate to a kind of composite bio-fertilizer promoting crop root growth and preparation method thereof.
Background technology
Root system is as the vitals of the water of crop entirety, fertile resource grabber and synthesis several physiological active substances, closely bound up with soil moisture, Nutrient distribution, migration and consumption, its spatial and temporal distributions in soil, not only determine that crop absorbs ability to moisture and nutrient within its vegetative period, also directly affect the building up of crop field top canopy, the distribution of assimilate and the formation of ultimate capacity.Optimize root function, regulate whole vine growth and development by root system, thus realize the object of high-yield and high-efficiency high-quality.
Different irrigation and fertilization measurements, produces obvious mediating effect+6 to crop root physiological activity.Liquid manure for reply crop root Growth and distribution and considerable influence has been absorbed to water and nutrient, thus have influence on growing of plant entirety, final decision output.
But existing conventional composite fertilizer mainly focuses on the supply of npk nutrient, and ignore macronutrient excessive cause soil compaction acidifying, plant root growth retardation phenomenon; Conventional microbiological fertilizer focuses on the exploitation improving the aspect functions such as utilization rate of fertilizer, improvement soil, raising crop resistance, and affect the root system being at all crop of crop yield, well developed root system just can better absorb nutrient, and plant could grow vigorous, thus could obtain high yield.Therefore, need badly and provide one to promote crop root growth, thus improve the composite bio-fertilizer of output.
Summary of the invention
In order to solve problems of the prior art, the object of this invention is to provide a kind of composite bio-fertilizer promoting crop root growth and preparation method thereof.
In order to realize the object of the invention, technical scheme of the present invention is as follows:
Promote a composite bio-fertilizer for crop root growth, described composite bio-fertilizer is prepared by the component of following weight part:
Described inorganic compositions is one or more in urea, ammonium nitrate, monoammonium phosphate, diammonium phosphate, potassium sulfate, Repone K; Described organic composite is one or more in fermentation clover slag, fermentation furfural dregs, fermentation mushroom residue, the fermented grape dregs of rice, wormcast.
As preferably, described composite bio-fertilizer is prepared by the component of following weight part:
Wherein, described composite bacterium powder is made up of subtilis, Bacillus licheniformis, bacillus laterosporus, photosynthetic bacterium and actinomycetes.
As preferably, subtilis, Bacillus licheniformis, bacillus laterosporus, photosynthetic bacterium and actinomycetes mix according to the concentration ratio of 1 ~ 2:1:2:1 ~ 2:2 ~ 3.
Further, the preparation method of described composite bio-fertilizer comprises the steps:
