摘要
通过"3414"施肥配比处理,研究了干旱区戈壁地不同施肥配比对干旱区戈壁地克瑞森无核葡萄果实性状及产量的影响。结果表明:N肥有利于葡萄产量的增加,但延迟果实成熟;而P、K肥有利于果实品质的提高,并能促进果实提早成熟。在本试验条件下,根据回归方程以及N、P2O5、K2O肥和葡萄价格计算,滴灌葡萄化肥的最佳施用量,N肥为13.8kg/667m2,P2O5肥为8.0kg/667m2,K2O肥为8.4kg/667m2。最高产量施肥量,N肥为14.6kg/667m2,P2O5肥为8.3kg/667m2,K2O肥为9.4kg/667m2。滴灌葡萄N、P2O5、K2O肥的最佳追肥配合比例为N:P2O5:K2O=1:0.58:0.61。
The effect of the various combined applications of fertilizers on fruit quality characters and yield of Crimson Seedless grape grown in gobi soil of dry region were studied, in which the fertilization treatment of ＂3414＂ was employed. The results showed that N fertilizer could increase grape yield, and P2O5, K2O fertilizers improved fruit quality well; N fertilizer delayed fruit ripening, and P2O5, K2O fertilizers could speed the fruit maturation. In this experimental condition, according to the regression equation analysis and the comparison of the prices of N, P2O5, K2O fertilizers and grape fruit in market, the best fertilization approach was drip irrigation fertilizer application rand the best fertilizer application amount was13.8kg/667m^2 of N fertilizer, 8.0kg/667m^2 of P2O5 fertilizer, 8.4kg/667m^2 of K2O fertilizer. The application amounts of various fertilizers for highest yield were 14.6kg/667m^2 of N, 8.3kg /667m^2 of P2O5, and 9.4kg/667m^2 of K2O. The best fertilization ratio of N, P2O5, K2O fertilizers for drip irrigation application method was 1：0.58：0.61.
