What about the latest serious drop of figs?

The phenomenon of fig falling occurs from time to time in the process of management, and some fruit growers find that their figs are seriously falling in the heart of Chinese cabbage when they mature, which seriously affects the income. So what is the cause of the serious drop of figs? Let's take a look.

1. Discomfort of soil pH value.

The root system of fig is relatively developed, and its ability to absorb nutrients is very strong. The reason for its luxuriant branches and leaves is the ability of roots. Although its requirements on the soil are not very strict, the adaptability is still relatively strong, but the soil pH value still has a certain impact. Figs are most suitable for growing in weakly alkaline or neutral soil, and the suitable pH value is between 7.2and 7.5. it is an alkaline-tolerant fruit tree and needs a lot of calcium in the growth process. Therefore, if the soil is slightly sour, it will affect the root vitality, poor nutrition absorption, resulting in serious fruit drop, if the soil partial acidity can be adjusted by lime to neutralize the soil acidity and alkali.

2. Water imbalance

Figs have luxuriant leaves and large and thick leaves, so the demand for water is more and more, and the rate of water evaporation is relatively fast, especially when the new shoots are extracted and the fruit expands rapidly. Therefore, if there is a lack of water in the growth stage and the soil is too dry, it will seriously affect the growth and development of fruit trees, resulting in rough pulp, small fruit, serious decline in yield and quality, and finally lead to ripening too early. dry and drop the fruit.

3. Diseases and insect pests

There are a variety of diseases and insect pests that cause serious fig drop, such as blight, root nematodes, longicorn beetles, mites and so on. Among them, the blight mainly harms fruits, new shoots and leaves, and also infects young buds; root nematodes mainly harm the roots of the plant, causing it to rot, swell, and shrink the root system, resulting in dwarfism of the plant, yellowing of leaves, and early fruit drop; longicorn beetles will feed vertically and horizontally under the skin of the plant, and then eat into the xylem and deep trunk, which will cause tree weakness and fruit drop. Mites will gather the back of the leaves with adult mites and nymph mites to absorb leaf juice, making the leaves lose function and cause falling leaves and fruits. The prevention and control of diseases and insect pests should be strengthened. after the diseases and insect pests are found, they should be controlled as far as possible.

4. Improper fertilization

Many growers often choose a single fertilizer when applying fertilizer, which often hinders the root system's absorption and utilization of other nutrients. For example, in nitrogen deficiency, the number of inflorescence differentiation will be reduced, resulting in early ripening and good quality of the fruit, but because of the transfer of nutrients to the fruit, it will cause serious fruit drop. When potassium is deficient, there will be excessive growth of shoots and abnormal fruits, and it will also lead to blackening, peeling and decay of roots, which will lead to fruit drop. Figs are also in great demand for calcium fertilizer, and calcium deficiency will also lead to early fruit drop. Therefore, fertilization must be reasonable, and sufficient basal fertilizer should be applied to provide material conditions for the growth and development of fruit trees. in fig cultivation, it is divided into early topdressing and late topdressing, that is, fertilizer is needed in each growth stage to regulate the contradiction between vegetative growth and reproductive growth to ensure high yield and high quality.
