How to improve the fruit setting rate in sweet peppers in early spring

In early spring, sweet peppers in greenhouses often encounter cold snow weather during the flowering period, which leads to poor flower bud differentiation of sweet peppers in greenhouses and serious flowering and fruit drop, which affects yield and income. Here's how to improve the fruit-setting rate of greenhouse sweet peppers. 1. Improve lighting conditions and increase temperature. In the case of cloudy snow and low temperature weather, an additional light can be added in the shed, and a light curtain can be hung on the back wall to increase lighting in the shed. Clean the film and improve the light transmittance of the film. Strengthen pruning and management of pruning, remove too many branches and leaves, especially the inner pruned leaves, improve the light rate of leaves and buds, reduce nutrient consumption, and thus increase the fruit setting rate. 2. Reduce the humidity in the shed and pollinate insects. Sweet pepper in the pollination period of the humidity is more demanding, encounter low temperature and even cloudy days, shed indoor humidity is too large, easily lead to sweet pepper pollen development, decreased activity, can not be completed normally pollination. Before and after noon, according to the weather conditions, you can let the air cool and dehumidify and reduce the humidity in the shed as much as possible. In addition, the release of bumblebees in sheds can significantly increase the fruit setting rate of sweet peppers. 3. Spray fertilizer and plant regulators. Boron is one of the essential elements for the differentiation of flower buds in sweet pepper. Boron deficiency often leads to poor flower bud development. For this reason, applying boron-containing liquid fertilizer before flowering can supplement the plants with nutrients and reduce fruit drop and fruit drop. Spraying 30 ~ 40 mg / kg of naphthalene acetic acid solution can also play a very good role in the preservation of fruit.
