摘要
对津春3号、津优1号、津优3号、津优30号、998等5个黄瓜品种的生长和养分吸收规律进行了两年的研究。结果表明,不同品种间吸肥特性存在着较大的差异,形成1000kg产量所需的N、P、K养分量也不同,以津春3号所需的N、P、K养分总量最多,998所需养分量较少,津优1号养分吸收受季节的影响较大。总结出不同品种施用N、P、K的最适配合比例。
The two-year studies on properties of growth and nutrients uptake for five cucumber varieties were carried out containing Jinchun No.3 Jinyou No.1 Jinyou No. 3 Jinyou No.30 and 998. The result showed that there are significant differences in different varieties. The amounts of N P K needed for producing 1 000 kg cucumber are different and Jinchun No.3 need the largest amounts of N P K while 998 need the least one. Seasons have shown strong effect on the growth and nutrients uptake of Jinyou No. 1. The best proportion of N、P、K utilization for different varieties was summarized.
