叶面喷施丰产素在黄瓜上的应用效果

Effects of leaf Surface Spraying "High yielding Regulator"in Cucumber

本试验在黄瓜上叶面喷施丰州牌丰产素，其浓度分别为２０００倍、４０００倍和６０００倍。试验结果表明，３种浓度对黄瓜的生长势都有增强的作用，并对早期产量有较大的提高。其中２０００倍液对早期产量的增产幅度最大，比对照提高４２．８１％。并且对黄瓜的营养成份有不同程度的影响，其中６０００倍液对维生素ｃ和含糖量都有较大的提高，因此，对黄瓜品质的改进有较好的效果。

This paper repqrts the effects of leaf surface spraying “high yielding regu-lator”(commercial name)with 2000,4000, 6000 times in cucumber. The results showedthat the regulator could promote the plant growth and obtain high yield,especially for theearly yield in various obvious on imcreasing yield. It could make the yield 42.8%higher thatthe comtrol.The spraying of the regulator could also improve the quality of the fruits,thecontent of the nutrient composition were raised by the treatments. The spraying with 6000times could make the vitamin C,sugar content remarkably increased
