Analysis of the Causes of Flower and Fruit Drop in Goji Berry and Control Methods
Goji berry (Lycium barbarum) is one of the well-known Chinese medicinal herbs, often used in daily life for health preservation and care. Goji berry is planted across a very wide area in China. During cultivation and production, serious flower and fruit drop is an important factor affecting goji berry yields. So what causes flower and fruit drop in goji berry? And how should it be controlled? Let's take a look together.
1. Too low temperature and low humidity
If the environment in which goji berry grows has a temperature above 35°C and a relative humidity below 40%, the plant, in order to adapt to this harsh environment of high temperature and low humidity, will begin to shed its leaves and fruits, regulating itself in this way to withstand the adverse environment.
Control method: When planting, choose a suitable area for cultivation, where the annual maximum temperature should not be higher than 35°C. When the relative humidity is low, humidity can be increased by watering or spraying.
2. Lack of fertilizer
During the full fruit stage of goji berry, both its plant growth and its heavy fruit load consume large amounts of nutrients, and this fertilizer-deficiency symptom is even more obvious when it is planted in poor soil.
Control method: Therefore, when growing goji berry, be sure to choose fertile ground for planting, and apply fertilizer in time during the growing period to supplement nutrients; this can alleviate the flower and fruit drop.
3. Soil drought
Although the root system of goji berry extends deep into the soil, its main absorption capacity is through root hairs, but root hairs need watering, and a large part of the nutrients is absorbed through contact with the root bark, yet this absorption capacity is weaker than that of root hairs. If the soil is dry and water cannot be replenished, it will cause flower and fruit drop.
Control method: When soil drought occurs, pay attention to timely watering and keep the soil moist; this is a key measure to alleviate flower and fruit drop.
4. Pests and diseases
Goji berry has many pests and diseases during cultivation. The main diseases include anthracnose, brown spot disease, powdery mildew, and root rot, while the pests include aphids, red gall midges, gall mites, and psyllids. They seriously affect the growth and development of goji berry and very easily cause flower and fruit drop as well as leaf drop. If not controlled in time, they can cause total crop failure in severe cases.
Control method: The control of pests and diseases must be timely, carried out in combination with agricultural control, physical control, and chemical control, to reduce the harm of pests and diseases to a minimum.
