What to Do About Flower and Fruit Drop in Goji Berry? Detailed Explanation of Causes and Control Methods
Goji berry is one of the Chinese medicinal herbs we are all familiar with, and it is often used in daily life for health preservation. Goji berry is planted over an extremely wide area in China, and during planting and production, severe flower and fruit drop is an important cause affecting goji berry yield. So what causes flower and fruit drop in goji berry? How should it be controlled? Let's take a look together.
1. Too low temperature and low humidity
If the environment where goji berry grows has a temperature above 35 degrees 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 region for cultivation; the annual maximum temperature should not be higher than 35 degrees. When relative humidity is low, humidity can be increased by watering more or by misting.
2. Lack of fertilizer
During the full fruit stage of goji berry, both plant growth and the large fruit load consume a great deal of nutrients, especially when planted in poor soil, where this symptom of fertilizer deficiency is even more obvious.
Control method: Therefore, when growing goji berry, be sure to choose fertile areas for planting, and during the growing period apply fertilizer promptly to supplement nutrients; this can alleviate flower and fruit drop.
3. Dry soil
Although the root system of goji berry extends deep into the soil, its main absorption capacity is mainly through root hairs, but root hairs need watering, while a large part of the nutrients is absorbed through contact with the root bark, which has weaker absorption capacity than root hairs. If the soil is dry and water cannot be replenished, it will cause flower and fruit drop.
Control method: When dry soil occurs, pay attention to watering promptly and keep the soil moist; this is a key measure to alleviate flower and fruit drop.
⟦NL>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 drop, fruit drop, and leaf drop. If not controlled promptly, they can cause total crop failure in severe cases.
Control method: The control of pests and diseases must be timely, combining agricultural control, physical control, and chemical control together to reduce the harm of pests and diseases to a minimum.
