Effect Of Different Fertilizer On Yield And Quality Of Red Globe Grape

Conventional methods of fertilization as the control, through the study of field experiments of Kraft paper packing slow-release fertilizer, Non-woven packaging bag slow-release fertilizer, Activity humic acid grape fertilization and a different dosage of four times into the N, P, K fertilizer on photosynthetic characteristics, leaf chlorophyll content,grain yield and quality of red globe grape etc. Research shows that:1、Different treatment and the control group of chlorophyll content change trend is rising as a whole. Four deals with chlorophyll content were higher than control group, but the difference between fertilization treatments is not obvious; Kraft paper packaging slow-release fertilizer of red globe grape leaf chlorophyll content is highest, reaches 4.35%, net photosynthetic rate increased by 4.85% at the same time, is advantageous to the grape leaf photosynthesis.2 、 Different fertilizer treatments are made of red globe grape quality, are improved to varying degrees. Kraft paper packaging of slow-release fertilizer use effect is the best, make the red earth grape fruit hardness increased by 4.85%, soluble solids content increased by8.0%, increased by 8.43% and reducing sugar acid ratio Vc increased by 67.59%, titratable acid content by 3.83%.3 、 Different fertilizer treatments on the red earth grape production is different, the influence of the kraft paper packaging slow-release fertilizer treatments increased amplitude is most obvious, was 24.1%, and the yield of 46093 kg/hm2, this processing also make hundred grain weight, weight per ear, grain diameter and ear longitudinal diameter increased to different extent.To sum up, Kraft paper packaging slow-release fertilizer can be used as an effective fertilization measures for promotion.
