硅钙钾肥对黄瓜生长发育的影响

Effect of Silicon-Calcium-Potassium Fertilizer on the Growth and Development of Greenhouse Cucumber

以黄瓜品种＂津优32号＂为试材,研究不同硅钙钾肥用量对黄瓜生长和产量的影响。结果表明：不同施用量硅钙钾肥能明显促进温室黄瓜株高生长,黄瓜生长健壮,茎粗增加,黄瓜蔓长增加,促进黄瓜早开花,结果数量增多,增加黄瓜的含糖量,口感更好;在施用量25-75kg/667m2范围内,温室黄瓜产量增加9.8%-21.3%;综合考虑硅钙钾肥用量应控制在50-75kg/667m2为宜。

Taking cucumber＂Jinyou 32＂as the test material,the effect of silicon-calcium-potassium fertilizer on growth and yield of greenhouse cucumber were studied.The results showed that different application amount of silicon-calciumpotassium fertilizer could significantly promote the growth of cucumber stem,stem diameter and vine length.Similarly,accelerated flowering of the inflorescence,increased the number of fruits.The yield of cucumber increased from 9.8%to21.3% under the silicon-calcium-potassium fertilizer 25-75kg/667m2.Comprehensive consideration,silicon-calciumpotassium fertilizer amount should be controlled at 50-75kg/667m2.
