Abstract
The invention discloses a soil improvement agent for the improvement of soil fertility in a tea garden, and belongs to the technical field of agricultural culture. The soil improvement agent comprises a mixed culture of a phosphorus-dissolving microbe and a potassium-dissolving microbe, wherein the mass ratio of the phosphorus-dissolving microbe to the potassium-dissolving microbe is (2.5-1):1. The soil improvement agent disclosed by the invention can be used for remarkably improving the supply ability of soil nutrients of the tea garden and accelerating the growth of a tea tree by being used as an organic fertilizer according to the application amount of 5-10 t/ha.
Description
Technical field
The invention belongs to agriculture culture technique field, relate to a kind of soil improvement agent of fostering and apply fertilizer for tea garden soil particularly.
Background technology
Phosphorus is one of basic nutrition element needed for plant-growth, and China has the arable soil of 74% to lack phosphorus. there is the phosphorus of more than 95% to be invalid form in soil. and plant is difficult to directly absorb, and wherein insoluble organophosphorus accounts for 20% ~ 50% of total Phosphorus In Soil.The utilization ratio being the phosphorus after fertilizer or inorganic fertilizer are used is all very low. and for tea garden soil due to nature with think the impact of factor, sour aluminium is in a large amount of enrichment of topsoil, and most phosphorus Fe, A1 with soil in are combined formation insoluble phosphate.In tea place, this season utilization ratio of phosphate fertilizer is for being only 5% ~ 20%, and the utilization ratio therefore how improving phosphorus is the problem that scholar and agricultural producer pay close attention to always.The utilization ratio of Soil Phosphorus affects by multiple factors, and microorganism occupies suitable component to the conversion of phosphorus and validity.The microorganism that insoluble phosphate can be converted into the form that plant available utilizes in a large number is there is in soil. the microorganism with this ability is called phosphate solubilizing bacteria or phosphorus-solubilizing bacteria.
China's Potassic fertilizer resources is also on the low side, need a large amount of import could meet the needs of agriculture production, our monitoring shows, the monitoring point that tea garden soil effective potassium in Jiangsu Province is greater than 100mg/kg only reaches 60% of total monitoring point number, and tea place potassium uptake of getting bumper crops should lower than 120mg/kg.Soil acidification easily increases the weight of agricultural land soil potassium deficiency trend.Therefore, how to improve tea garden soil available phosphorus, potassium amount, how improving soil is the problem that urgently will solve.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is for solving problems of the prior art, providing a kind of soil improvement agent of fostering and apply fertilizer for tea garden soil, can significantly improve tea garden soil indigenous nutrient supply capacity, promotes the effect of growth of tea plant.
(2) technical scheme
A kind of soil improvement agent of fostering and apply fertilizer for tea garden soil is the present invention proposes in order to solve the problem, described soil improvement agent comprises phosphate solubilizing microorganism, silicate-dissolving microbe culture, wherein, the mass ratio of phosphate solubilizing microorganism, silicate-dissolving microbe culture is (2.5 ~ 1): 1.
Particularly, described phosphate solubilizing microorganism liquid nutrient medium consists of: molasses 5-10 ‰, soybean protein powder 3-5 ‰, yeast extract paste 5-8 ‰, potassium primary phosphate 5-10 ‰, magnesium sulfate 1.5-3.0 ‰, sodium-chlor 1.0-15 ‰, corn steep liquor 3-5 ‰; Fermentation condition is temperature 28 ~ 32 DEG C, and initial pH value is 7.0 ~ 7.5, inoculum size 1%, shaking speed 200r/min; Cultivate 48h. add again 12 ~ 15% ammonium sulfate (M/V), 10 ~ 12% peat (M/V) and 6 ~ 8% (M/V) calcium carbonate continuation fermentation 24 after, complete production.
Particularly, the cultural method of described silicate-dissolving microbe is: send out in the solid materials that increased to by original Bacillus and 10 ~ 30 DEG C of bottom fermentations 15 ~ 18 days, obtain genus bacillus number and be at least 1.2 × 10
10the culture of individual/g.
Particularly, described solid materials is made up of the solid mixture and water waiting weight part, wherein, solid mixture is made up of, at 10 DEG C with top fermentation 15 days 40 parts, rice bran, 50 parts, wheat bran, soybean cake powder 5 parts, Semen Maydis powder 5 parts, 0.05 part, magnesium sulfate and manganous sulfate 0.01 part.
Described soil improvement agent in tea place as organic fertilizer application in tea place, amount of application is 5 ~ 30t/ha.
(3) beneficial effect
The present invention seriously lacks the slower feature of available phosphorus, potassium and tea tree Leaf Litter Decomposition according to tea garden soil, use a kind of phosphate solubilizing microorganism, silicate-dissolving microbe culture, promote the release of stationary state phosphorus in tea garden soil, and the decomposition by using a kind of tea tree endophyte to promote tea tree fallen leaves, eliminate the allelopathy of polyphenol substance.According to the actual demand of tea garden soil nutrient supply characteristic and Tea Production, after the bacterial strain of difference in functionality is independently cultivated separately, soil improvement agent is made into the form of composite flora, this preparation is used as fertilizer and applies tea garden soil, soil improvement agent used is that matrix cultivates acquisition with agricultural wastes, cost is low, and simultaneously tool is significantly improved tea garden soil indigenous nutrient supply capacity, promotes the effect of growth of tea plant.
Embodiment
Below in conjunction with specific embodiment, the embodiment of invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting scope of invention.
The invention provides a kind of soil improvement agent of fostering and apply fertilizer for tea garden soil, it is characterized in that, described soil improvement agent comprises phosphate solubilizing microorganism, silicate-dissolving microbe and Endophytic Fungi in Tea Trees culture, wherein, phosphate solubilizing microorganism, silicate-dissolving microbe mass ratio are the preparation of the soil improvement agent that 2.5 ~ 1:1 fosters and apply fertilizer for tea garden soil.
Embodiment 1
(1) cultivation of phosphate solubilizing microorganism: after original flora amplification, ferment in solid culture medium.Described culture material is: molasses 5-10 ‰, soybean protein powder 3-5 ‰, yeast extract paste 5-8 ‰, potassium primary phosphate 5-10 ‰, magnesium sulfate 1.5-3.0 ‰, sodium-chlor 1.0-15 ‰, corn steep liquor 3-5 ‰; The most adaptable method is temperature 30 DEG C, and initial pH value is 7.0 ~ 7.5, inoculum size 1%, shaking speed 200r/min; Cultivate 48h. add again 12 ~ 15% ammonium sulfate (M/V), 10 ~ 12% peat (M/V) and 6 ~ 8% (M/V) calcium carbonate continuation fermentation 24 after, complete production.
