越夏甜椒落花落果的原因有很多,高温、肥水、药物使用不当及病虫害的发生等都会导致。1.温度原因如果温度过高(高于35℃),会因花器发育不全或柱头干枯导致授粉受精不良而落花落果。此外,夏季夜温高,植株容易徒长,营养生长过旺也会造成落花落果。因此,白天可以采取泼泥浆等方式降低棚内温度,夜间敞大通风口降低夜温。花期温度控制以白天20~27℃,
There are many reasons why sweet peppers fall and blossom in summer. The causes of high temperature, fertilizer and water, improper use of medicines and the occurrence of pests and diseases will all result. 1. Temperature reasons If the temperature is too high (higher than 35 ℃), will be due to hyphae hypogynterosis or stigma leading to pollination and poor flowers and fruit drop. In addition, the summer night at high temperatures, plants tend to be leggy, vegetative growth can also cause excessive loss. Therefore, the mud can be taken during the day and other ways to reduce the greenhouse temperature, open night large ventilation to reduce the night temperature. Flowering temperature control during the day 20 ~ 27 ℃,
