Research On Effects Of Formulated Fertilization On Soil Physicochemical Properties And Fruit Quality Of Summer Black Grape

Longquanyi Districtisan important producer of grapesin Sichuan, And grapes is the source of incomeoflocalfarmers.However, due toirrational fertilization. Resulting i na serious decline invineyardsoilfertility. Not colored and branchesrecession and Poo rtastes is Widespreadproblem in Grapes. Seriously affect thevalue of their goods, Red ucing the farmers’enthusiasm for production. So, takingfertilizationtests,findscientific of Fertilization Formula. Thus restoring thelocal vineyardssoilfertility.tolmprovethe c ommercial value ofgrapes, Asfarmersincrease revenue, it has important practical an d theoretical significance.Taking 3-year-old trees of summerblack grapesas test material in Sichuan Long quanyi District.through the determination and analysis of Soil Background value,det ermining the amout of fertilizer based on Target Yield Method,and orthogonal desig n was adopted to set different balanced fertilization formula in order to study the e ffects of formula Fertilization on Soil physicochemical properties and fruit quality The resultsare as follows:1. ReasonableFormula Fertilizationcan significantly reducesoil bulk density,adjust the soilpH,Increasesoil porosity,Increase soil organic matter,and relievethe physicalde terioration of soilindicators,Treatment 4, namely each plant was supplied for dried chicken manure 2kg,Quicklime 0.2kg. sprout plants fertilizerUrea 0.17kg,Availableb oron 0.01kg,Strongfruit fertilizer fertilized Monoammonium 0.083kg, Potassium 0.204 kg, is best on the combined effect of improving of soil physical properties.Through out the growing season,0-30cmsoilplace Soilbulk density decreased 0.06%,Increase soil organic matter 0.38%,Soil pHincreased0.35%,increasedsoil porosity 2.23%.Signifi cantly higher than CK,Using conventionalfertilization,Thesoil physicalindicators aredet eriorating.2. Formula Fertilizationcan balance thesoil available nitrogen, available phospho rus,available K in each period.Maintainsoil exchangeablemagnesiurn,effectiveFe,effe ctiveZn,effectiveMn Soil fertilitylevelsinmicronutrients.The presenceof tested soil had nitrogen-rich,lowPhosphorus Potassium problem.Formula Fertilizationcan reducesoil av ailableN content,Increase soilavailable P,Kcontent,throughout the growing season 0 30cmsoilplacedecreased available nitrogen.3.81mg/kg-24.18mg/kg.Available phosph orusincreased 4.11mg/kg～5.35 mg/kg,Available Kincreases 42.27 mg/kg～56.85 mg/k g,Throughout the growing season,Since nosoil applicationofmicronutrient fertilizer Soi 1 exchangeablemagnesium,EffectiveFe,effectiveZn,effective Mn was declining, but the declinewas significantlyslower thanthe degree ofcontrol.3.
