In planting and production, serious flower and fruit drop is an important reason that affects the yield of Chinese wolfberry. So what is the reason for Chinese wolfberry falling flowers and fruits? How to prevent and cure it? Let's take a look.

1. The temperature is too low and humid

If the temperature of Chinese wolfberry is more than 35 degrees and the relative humidity is less than 40%, in order to adapt to the harsh environment of high temperature and low humidity, its leaves and fruits will begin to fall off, so as to adjust itself and resist the adverse environment.

Prevention and control methods: suitable areas should be selected when planting, and the maximum temperature for the whole year should not be higher than 35 degrees. When the relative humidity is low, watering or spraying can be used to increase humidity.

2. Lack of fertilizer

In the full fruit period of Chinese wolfberry, its plant growth and fruiting amount is large, and it needs to consume a lot of nutrients, especially when planted on barren soil, the symptom of fertilizer deficiency is more obvious.

3. Soil drought

Although the root system of Chinese wolfberry goes deep into the soil, its main absorption is mainly through root hairs, but root hairs are watered, and a large part of nutrients are absorbed through root bark contact, but it is weaker than root hairs, and if the soil is dry, water can not be replenished, it will cause flower and fruit drop phenomenon.

Prevention and control methods: when there is soil drought, we should pay attention to timely watering and keep the soil moist, which is the key measure to alleviate the falling flowers and fruits.
