冬春茬辣椒的落花、落叶、落果,始终是影响辣椒高产的一大障碍。我们通过几年来的生产实践,总结出一套行之有效地防治辣椒“三落”的新措施。 冬季长期低温,辣椒因花粉管伸长受阻而落花。为此,必须优化棚型结构,采取多层覆盖,必要时短时加温,使温室内的温度保持在15℃。春季温度不断上升,此时要注意加强通风,不要使室内温度长时间高于35℃,否则花粉会失去活性,导致受精不良而落花。
Spring and winter peppers falling, deciduous, fruit drop, pepper has always been a major obstacle to high yield. Through several years of production practice, we summed up a set of effective measures to prevent peppers “falling” new measures. Long-term low temperature in winter, peppers due to obstruction and pollen tube drop flowers. To this end, we must optimize shed structure, to take multi-layer coverage, if necessary, short-term heating, so that the temperature inside the greenhouse maintained at 15 ℃. Spring temperatures continue to rise, this time to pay attention to strengthening the ventilation, do not make the room temperature for a long time higher than 35 ℃, pollen will lose its activity, resulting in poor fertilization and falling.
