摘要:
运用正交实验设计,研究了不同肥料搭配对少花龙葵生长、产量及品质等指标的影响.结果表明:尿素施用量在38.08 g/m2、硫酸钾在16.16～22.66 g/m2、过磷酸钙在16.30～24.50 g/m2对少花龙葵的株高、叶数、开展度、叶面积、产量和品质有明显的促进作用;在高氮的条件下,硫酸钾、磷酸二氢钾有利于提高可溶性糖和维生素C的含量,过磷酸钙有利于提高可溶性蛋白的含量;产量与叶数、开展度和叶面积之间存在明显的正相关.
Abstract:
In an experiment with the orthogonal design, the plants of Solannum photeinocarpum Nakamura et Odashima were supplied with N, P and K in different combinations to study their effects on the growth,yield and quality of the crop. The results showed that the combination of CO (NH2)2 at 38.08 g/m2 +K2SO4 at 16.16～22.66 g/m2 +Ca(H2PO4)2 at 16.30～24.50 g/m2 had remarkable promoting effects on plant height, leaf number, expansion diameter, leaf area, yield and quality of S. photeinocarpum, that under high nitrogen rate conditions, K2 SO4 and KH2 PO4 benefited the content of soluble sugar and vitamin C and Ca(H2PO4)2 benefited the content of soluble protein, and that yield was in significant correlation with leaf number, expansion diameter and leaf area.
