How to improve the Fruit setting rate of planting Sweet Pepper in greenhouse
How to improve the fruit setting rate of planting sweet pepper in greenhouse? Please give guidance to the greenhouse sweet pepper in the flowering and fruiting period will often encounter overcast snow and low temperature weather, resulting in serious greenhouse flower and fruit drop phenomenon, affecting the yield and income. This paper introduces several methods to improve the fruit setting rate of sweet pepper in greenhouse: 1. To improve the lighting conditions and increase the temperature in case of overcast, snowy and low temperature, supplementary lights can be added in the shed, and a reflective screen can be hung on the back wall to increase the illumination in the shed. Clean the greenhouse film and improve the light transmittance of the greenhouse film. Strengthen the management of pruning and branching, remove too many branches and leaves, and reduce nutrient consumption, so as to improve the fruit setting rate. two。 To reduce the humidity in the greenhouse, insect pollination sweet pepper has more stringent requirements on humidity during the flowering and pollination period. in the case of low temperature and continuous overcast days, the humidity in the greenhouse is too high, which can easily lead to pollen hypoplasia, reduced activity and can not complete pollination normally. Around noon, according to the weather conditions, it can be released to cool and dehumidify and reduce the humidity in the shed as much as possible. 3. Spraying micro-fertilizer and plant regulator boron is one of the essential elements for flower bud differentiation of sweet pepper. Boron deficiency often leads to flower bud dysplasia. Spraying boron-containing liquid fertilizer before flowering can supplement nutrition for plants and reduce flower and fruit drop. Spraying 30mg / kg naphthylacetic acid solution can also play a good role in flower and fruit protection.
