摘要
通过田间试验，研究了氮磷钾配施及有机肥对瓠瓜生长和品质的影响。结果表明，氮磷钾配施能够提高瓠瓜产量，增产幅度1500．0—29166．6kg／hm^2，增产率2．7％～101．7％。各营养元素对瓠瓜产量提升贡献的大小顺序是N〉K〉P。瓠瓜品质特别是Vc、总糖含量得到提高。在氮磷钾配施的基础上再施有机肥，产量更高，品质更好，经济效益更佳。
In field experiment, effects of N, P, K and organic fertilizers on growth and quality in Lagenaria siceraria were investigated. Results showed that N, P, K fertilizers increased Lagenaria siceraria yield by the amount that reached to 1 500. 0 -29 166.6 kg/hm^2, and the yield increase rate was 2. 7% - 101.7%. Among N, P, K fertilizers, the effects of increasing Lagenaria siceraria yield was in the order of N 〉 K 〉 P. Lagenaria siceraria quality also increased, especially the content of Vc and sugar. Applied organic fertilizers in addition to N, P, K fertilizers, Lagenaria siceraria yield, quality and economic benefit improved better.
