优化施肥对南方丘陵山地毛葡萄产量效益的影响

Effect of Optimized Fertilization on Yield and Economic Benefit of Vitis quinquangularis Rehd. in Hills and Mountains of Southern China

采用＂416-B＂最优混合设计,研究石灰、钾、磷、氮与毛葡萄‘野酿2号’产量效益关系。结果表明：在1水平时,石灰、钾、氮对毛葡萄产量的单因素效应达到最高;其产量分别为17014.53、17150.77、16754.57 kg/hm2。而磷在水平为0.604时产量达到最大,其产量为16 623.72 kg/hm2。在整个-1.518~1.518编码水平中,石灰与钾,石灰与磷对毛葡萄产量交互效应表现为正效应,在-1.518~0范围中,其他各因素两两间对毛葡萄产量的交互效应均表现为正效应。综合考虑高产、经济高效时,石灰、钾、氮、磷最优施肥方案为0.982（1976.28 kg/hm2）,0.982（322.03 kg/hm2）,-0.518（173.82 kg/hm2）,-0.550（75.34 kg/hm2）,此时其产量为17 983.32 kg/hm2,利润为87832.00元/hm2。

With design of the superior hybrid design‘416-B＇,experiment was conducted to study the effects of lime,potassium,nitrogen,phosphorus on the yield and economic benefit of Yeniang No. 2 Vitis quinquangularis Rehd. The results showed that lime,potassium,nitrogen on grape yield reached the highest single factor effect at the 1 level. The yield were 17014. 53,17150. 77,16754. 57 kg / hm2 respectively. And phosphorus reached the highest single factor effect at the 0. 604 level. The yield was 16623. 72 kg / hm2. At the coded level- 1.518 to 1. 518,lime and potassium,lime and phosphorus on yield interaction Vitis quinquangularis Rehd. had a positive effect. At the coded level- 1. 518 to 0,the interaction effect on Vitis quinquangularis Rehd. yield factors showed positive effect. Considering the high yield and economic benefit,the optimized fertilization was lime 1976. 28 kg / hm2,potassium 322. 03 kg/hm2,nitrogen 173. 82 kg/hm2,phosphorus75. 34 kg / hm2,the yield was 17983. 32 kg/hm2,it＇s profit was 87832. 00 yuan /hm2.
