Abstract

The invention discloses a dedicated soil improver formula for a northern brown soil newly built tea garden. The dedicated soil improver formula mainly comprises the following components in parts by weight: 11-14 parts of aluminum sulfate, 3-6 parts of monopotassium phosphate, 10-13 parts of ferrous sulfate, 3-6 parts of zinc sulfate, 28-35 parts of urea, 50-100 parts of humic acid, 50-70 parts of biochar and 100-150 parts of grass carbon. The dedicated soil improver formula for the northern brown soil newly built tea garden disclosed by the invention can be fully stirred, uniformly mixed and applied to soil before tea seedlings are transplanted half-month ago. By adjusting the soil structure and the physical and chemical properties, the viscidity and the pH value of soil are reduced; the content of organic matters is improved; and the growth of lateral roots of the tea seedlings is beneficially accelerated, so that the tea seedling transplant survival rate is improved.

Description

A kind of northern brunisolic soil newly-built tea place special-purpose soil modifying agent formula

Technical field

The present invention relates to agricultural fertilizer field, be specially a kind of northern brunisolic soil newly-built tea place special-purpose soil modifying agent formula.

Technical background

According to trivial stroke of China's tea, major part tea district, the north of the Changjiang River of China is brunisolic soil, and soil stickiness is large, pH value is generally higher, and generally between 6.5-7.0, and tea tree is a kind of happiness acid fearness alkali plant, the soil pH value being suitable for planting tea should below 6.5, and optimum soil pH value is between 4.0-5.5.The tea place of the tea shoot that northern tea district is newly transplanted or new sowing, normal exist the phenomenons such as difficulty of taking root, surviving rate are low, makes young plant retarded growth, the serious development hindering the newly-built tea place of northern brunisolic soil.In order to tea place can be developed under the edaphic condition of higher ph, improve the surviving rate of transplanting tea shoot, promote the normal development of young plant, must improve soil before plantation tea tree, make soil pH value reach tea tree to take root optimum state, the various elements being conducive to root system development reach rational proportion.

The present inventor shows through test for many years, the elements such as AL, Fe, Zn all have the function promoting that tea tree takes root, Tai-Ace S 150, ferrous sulfate and zinc sulfate are all a kind of acidic substance, the pH value that significantly can reduce soil is used in soil, compounding application humic acid can make soil pH value reach the optimum regime of tea root growth, and soil acidity can be made to maintain the long period; Simultaneously, because brunisolic soil relative tack is larger, the solid phase of soil, liquid phase, gas phase " three-phase " are than unreasonable, be unfavorable for that tea root is grown, by using the material such as biological carbon, the peat composed of rotten mosses, the permeability of soil can be improved significantly, increasing organic matter and the carbon nutrition of soil, be conducive to the root system development improving young plant, improve the surviving rate of tea shoot.

Summary of the invention

Newly-built tea place special-purpose soil modifying agent formula under the object of this invention is to provide a kind of northern brunisolic soil condition, according to a kind of tea place of this formulated special-purpose soil modifying agent, by using this modifying agent, Soil structure and physico-chemical property can be adjusted, reduce soil stickiness and pH value, improve soil C, N nutrition, for tea tree growth of seedling provides suitable rhizospheric environment, promote tea shoot lateral root growth, thus improve transplanting survival rate, promote growth of tea plant and improve output.

The technical issues that need to address of the present invention, one is select which kind of reagent, can reduce soil stickiness and pH, improve soil physico-chemical property, can promote lateral root growth again; Two is how rational proportion reagent, can meet newly to transplant nutrient needed for tea shoot root growth and development, can ensure again root system and shoot length maximum.

Technical scheme of the present invention is: a kind of northern brunisolic soil newly-built tea place special-purpose soil modifying agent is filled a prescription, it is characterized in that being made up of the proportioning raw materials of following weight part: 11 ~ 14 parts, Tai-Ace S 150, potassium primary phosphate 3 ~ 6 parts, 10 ~ 13 parts, ferrous sulfate, 3 ~ 6 parts, zinc sulfate, 28 ~ 35 parts, urea, humic acid 50 ~ 100 parts, biological carbon 50 ~ 70 parts and the peat composed of rotten mosses 100 ~ 150 parts.Be manured into soil before tea shoot transplants first quarter moon by abundant for above raw material stirring and evenly mixing, when tea shoot is transplanted, P in soil H drops to 5.0-5.5 by 6.5-7.0; Soil stickiness reduces by 12% ~ 30%; In soil, each nutritive element changes easy absorbed ratio and form into.

Preferred version of the present invention is: 13 parts, Tai-Ace S 150, potassium primary phosphate 4 parts, 12 parts, ferrous sulfate, 4 parts, zinc sulfate, 30 parts, urea, humic acid 70 parts, biological carbon 60 parts and the peat composed of rotten mosses 120 parts.

Mechanism of the present invention is: tea tree is a kind of oxyphiles, and acid soil physically well develops, and is suitable for planting the soil pH value of tea roughly between 4.0-5.5.North brunisolic soil newly-built tea garden soil pH is higher, soil stickiness large, the factors such as exchangeable aluminum content is low cause new tea shoot of transplanting to take root difficulty in soil, and surviving rate is low.During the present invention is raw materials used, Tai-Ace S 150 can promote lateral root development, reduces P in soil H, increases exchangeable aluminum content in soil, improves tea tree to Fe ³⁺, Fe ²⁺absorbing of the element such as-EDTA, P; The proportioning that potassium primary phosphate, urea are suitable and and the mutual regulating effect of Tai-Ace S 150, provide not only N, P, K element, more facilitate the efficient absorption of tea tree to nutritive element.Ferrous sulfate, originally as acidic fertilizier, is conducive to reducing soil pH, and can improves tea yield.Humic acid, the peat composed of rotten mosses itself have acidity, be not only Tai-Ace S 150, ferrous sulfate acidifying provides medium, and reduce consistency of soil, provide organic.Applying biological carbon not only can improve soil, can also increase the carbon source in soil, is conducive to the growth of tea tree seedling.

Effect of the present invention is: transplant this soil improvement agent of tea preemergence application in newly-built tea place, soil pH value drops to 5.0-5.5 by 6.5-7.0; Tea shoot survival rate more than 92%, than not using, contrast is high by more than 60%; Tea shoot well developed root system, shoot length increases.

Embodiment
