施肥处理对大肉丝瓜产量和肥料利用的影响

为了更好地了解肥料在大肉丝瓜上的应用效果,在江门进行了不同氮磷钾肥料和有机肥试验.结果表明,氮肥对大肉丝瓜产量和生物量的影响最大,增加有机肥,可以提高前期产量和总产量,肥料的农学效率、偏生产力和利用率在低水平表现较好.通过回归分析,获得肥料效应方程,求得最佳施肥量,大肉丝瓜要获得高产和高效,江门地区推荐每667 m2商品有机肥最佳施肥量为250 kg,氮磷钾最佳施肥量为N 23kg、P2O511 kg、K2O 17 kg.

Effects of different fertilization treatments on meat luffa yield and fertilizer use

In order to better understand the effects of fertilizer on meat luffa, different nitrogen, phosphorus and potassium fertilizer and organic fertilizer experiments were carried out in Jiangmen. The results showed that, the effects of nitrogen fertilizer on meat luffa were the greatest maximum, increasing organic fertilizer could improve the early yield and total yield, the fertilizer agronomic efficiency, partial factor productivity and utilization rate were better in the low level. Through regression analysis, the equation of fertilizer effect was obtained, and the optimum amount of fertilizer was calculated. To obtain high yield and high efficiency, in Jiangmen area, the recommended amount of commercial organic fertilizer per 667 m2 250 kg, the optimum amount, of nitrogen, phosphorus and potassium were as follows: N 23 kg, P2O5 11 kg, K2O 17 kg.
