随着蔬菜生产的发展,夏菜的定值期不断提早,但由于定植时温度尚低,茄果类蔬菜易发生落花落果,黄瓜易引起化瓜,尤其是大棚黄瓜生长前期更为明显。目前对于茄果类的落花落果用2,4—D,PCPA处理已能达到较好的效果,而对瓜类化瓜问题至今未有较好的解决方法。小川幸恃等以BA和GA3、G
With the development of vegetable production, summer vegetables set the value of the early period, but the temperature is still low colonization, solanaceous vegetables prone to falling flowers, cucumbers easily lead to melon, especially in the early growth of greenhouse cucumber is more obvious.
