Boron deficiency
In the winter because of the ground temperature is low, the root absorption ability is weak, and nitrogen and potash fertilizer application, the unreasonable often inhibit the absorption of boron element, cause style dysplasia phenomenon.Solution: leaf spraying rate of boron or borax, promote style development.
Flower bud differentiation of bad
Had low temperature in winter and cold invasion, makes PengShi temperature below 5 ~ 8 degrees Celsius, for a long time lead to adverse, flower bud differentiation caused out of fruit drop and styles short phenomenon.Solution: we need to do the arrival of cold insulation work, reduce the damage in low temperature.
Too wet
PengShi too dry or humidity is too big, can cause the phenomena of flower bud differentiation of bad cause styles short.Solution: keep see dry wet soil, provide more reasonable wet conditions for plant growth, reduce styles short phenomenon.
Weak light, low temperature
Winter PengShi light and lower temperature, and continuous cloudy, photosynthesis is weak, lack of photosynthetic product, cause the nutrition supply, short phenomenon caused the pole.Solution: early jie late cover cover, a reflective screen, measures such as increasing light intensity and illumination time, reduce the stigma short phenomenon.
