- 摘要:
- 以丝瓜品种“江蔬一号”为试材,采用完全随机区组设计方案进行大田试验,研究氮、磷、钾肥配施对丝瓜苗叶绿素含量、丝瓜果实干物质含量、品质和产量的影响。结果表明:硝酸钾∶过磷酸钙∶硫酸钾(2∶1∶1.5)T4处理组丝瓜单瓜的干重和鲜重最高,硝酸钾∶过磷酸钙∶硫酸钾(1∶1∶1.5)T2处理组干物质含量最高,其次为T4处理组。总叶绿素含量T4处理组最高,其次为硝酸钾∶过磷酸钙∶硫酸钾(1∶1∶3)T3处理组、复合肥(1 500 g)T7处理组和硝酸钾∶过磷酸钙∶硫酸钾(1∶1∶0.5)T6处理组;叶绿素a/b含量最高为T7处理组,其次为T3、T6及T4处理组;类胡萝卜素含量最高为T4处理组,其次为T6和T3处理组。丝瓜果实中可溶性糖含量最高的处理组为T2,其次为T4处理组;可溶性蛋白质含量最高为T7处理组,其次为T4处理组。CK组丝瓜的早期产量和总产量均为最低;T4处理组的前期产量和总产量均最高,分别比CK提高18.54%和28.76%。T4处理组可显著提高丝瓜的产量和品质,为丝瓜施肥最佳配比。
- Abstract:
- The luffa variety ‘Jiangshu No.1’ was used as test material,a field experiment was conducted using completely randomized block design to investigate effect of combined application of nitrogen (N),phosphorus (P) and potassium (K) fertilizers on chlorophyll content,fruits dry matter content,yield and quality of luffa.The results showed that single luffa dry weight and fresh weight of potassium nitrate∶calcium superphosphate∶potassium sulphate (2∶1∶1.5)T4 treatment were the highest,dry matter content of potassium nitrate∶calcium superphosphate∶potassium sulphate (1∶1∶1.5) T2 treatment was the highest,followed by T4 treatment.T4 treatment had the highest total chlorophyll content,followed by potassium nitrate∶calcium superphosphate∶potassium sulphate(1∶1∶3) T3,compound fertilizer (1 500 g) T7 and T6 treatment.T4 treatment had the highest carotenoid content than other treatments,followed by T6 and T3 treatments.The content of the soluble sugar of T2 treatment was the highest,followed by T4 treatment;the content of the soluble protein of T7 treatment was the highest,followed by T4 treatment.Early yield and total yield of CK were the lowest.Early yield and total yield of T4 treatment were the highest and increased by 18.54% and 28.76% when compared with CK.T4 treatment which could increase yield and quality of luffa was the best on the ratio of fertilization.
