The reasons for the small size of the pepper fruit are mainly the following two aspects:
1. The cultivation environment is poor. Pepper plants are affected by drought, temperature discomfort (below 13°C or above 35°C) and other factors. Pollen cannot grow and spread normally. Pistil can not be fertilized normally and form unisexual fruit. This kind of fruit is easy to form stagnant fruit due to lack of growth hormone. Excessive fertilization may cause burning roots or serious damage to pests, leading to malnutrition of the fruit and the formation of stale fruit.
2. Too much fruit. When the plants grow weakly and fruit sets are too much, some fruits that are late in fruiting or in poor position will not be able to provide enough nutrients to form a stale fruit.
Prevention and control measures: 1. Put a good set of customs. When planting, the soil should be leveled with the soil, then covered with earth 3-5 cm thick, timely pouring root water to prevent drought. During the flower bud differentiation period, drought should be prevented and water should be used to promote rooting at other times. During flower bud differentiation and pollination and fertilization, the daytime temperature in the protected area was controlled at 23°C-30°C, nighttime at 15°C-18°C, and ground temperature at 17°C-26°C.
2. Timely seedlings. In the two true leaves, the seedlings should be prevented from damaging the roots too late to affect the nutrient supply during flower bud differentiation. When seedlings can be used 700-1000 times zinc sulfate rooting to promote root growth.
3. Plant adjustments. The number of plants to set fruit should be appropriate, should be based on the growing trend of the plant fruit, excess fruit should be removed as soon as possible, and timely control of pests and diseases.
