摘要
葡萄是新疆主要的特色果树,合理施肥是提高产量和商品率的重要技术措施。应用"3414"田间肥料试验设计,于2009-2010年连续两年,对戈壁地克瑞森无核葡萄进行田间肥效试验。结果表明:施氮增加了葡萄果实的纵横径、单果质量和产量;施磷对果实纵横径无显著影响,但增加了可溶性固形物含量和果实硬度;施钾对产量无明显影响,但明显提高了可溶性固形物含量。在该试验条件下,施氮对增产效果最好,磷肥、钾肥有利于果实品质的提高;结合当地葡萄生产实际,确定最佳氮磷钾施肥推荐用量分别为:N138.47 kg/hm2,P2O5 72.97 kg/hm2,K2O 78.83 kg/hm2,由此得出最佳产量为10516.2 kg/hm2。
Grape is the main fruit tree in Xinjiang. Reasonable application of fertilizer is an important technical measure for increasing grape yield and commodity rate. From 2009 to 2010, this study was conducted to investigate the fertilizer efficiency on field in gobi soil of Crimson Seedless, which used experimental design of 3414. The results showed that the use of N could increase the grape longitudinal, single fruit weight and yield. P fertilization couled increase the content of soluble solids and fruit firmness, but had no effect on longitudinal. The application of K led to the increasing of soluble solids with no significant effect on yield. The effect of N was significant for yield and P, K fertilization improved the fruit quality. According to the local grape field production, the best recommendation formula combination should be pure N： 138.47 kg/hm2, P205：72.97 kg/hm2, K20：78.83 kg/hm2 respectively. By using this formula, the best yield obtained was 10516.2 kg/ hm2.
