由于枣树开花期间喜欢高温而又湿润的气候,这样枣花的蜜质足,花丝干得慢,授粉好,枣子结得多。但因有些地区的气候条件不能满足它的要求,因此座果率较低。能不能提高座果率呢?据河北省沧县实践证明,在枣树盛花期喷1～2次水,每株树喷5—6斤,可比不喷水增产15%左右。如果喷生长刺激素,增产效果更为显著。常用萘乙酸液和“2.4—D”液。这两种植物生长刺激素,能刺激开花,减少脱花落果,同时 Jujube flowering like damp and humid climate during the day, so jujube flowers of honey, silk dried slowly, pollination, jujube knot more. However, because of the climatic conditions in some areas can not meet its requirements, so the fruit yield is lower. Can increase the rate of fruit set? It is proved that Cang County, Hebei Province, practice, in the flowering date jujube spray 1 or 2 times the water, each tree spray 5-6 kg, comparable to non-spray water yield of about 15%. If you sprout growth hormone, yield more pronounced. Common naphthalene acetic acid solution and “2.4-D” solution. Both plant growth hormone, can stimulate flowering, reduce deciduous fruit, at the same time
