The falling, falling fruit, and fallen leaves of peppers are commonly referred to as "three falls" of peppers. The cause of the "three falls" of pepper is more complicated, but in general, there are mainly the following points:
1 Early cold weather affected pollination and insemination caused early flowering and fruit drop.
2 improper fertilization, resulting in falling flowers, such as nitrogen or insufficient, causing vegetative growth and reproductive growth imbalance, resulting in falling, falling fruit.
3 The soil and air are too dry, affecting root absorption and leaf transpiration resulting in falling flowers and fallen leaves.
4 improper irrigation, resulting in dead plants or fallen flowers, fallen leaves, such as rapid watering in the high temperature noon with muddy water, resulting in weakened or damaged plant root absorption, resulting in plant death or falling flowers, the correct method is: in the morning or evening, slow irrigation with clear water , conducive to the growth of pepper fruit.
5 Due to the high temperature and drought conditions, other diseases and insect pests have occurred, causing flowering and fruit drop.
The key measures for prevention are: nurturing strong seedlings, strengthening fertilizer and water management, and strengthening the resistance of plants, especially during the hot season, timely top dressing, irrigation or drainage. Ground cover is needed when necessary to reduce soil surface temperature to reduce rain erosion and protect the root system. In the annual production and management of peppers, root growth, root protection, hair rooting, and root development should be promoted to promote the normal growth and development of peppers so as to prevent the "three falls".
In addition, some growth regulation benefits can also be used, such as 25-30 PPM anti-dropping agents sprayed at the flowering period, can receive good results.
