Citrus young fruit slow to turn green? Here comes the latest solution

After the flowers of citrus fade, if the phenomenon of young fruit turning green slowly appears, you must pay attention to it. This is a dangerous phenomenon, indicating that the plant's nutrition cannot keep up, and a large amount of fruit drop will occur during the second physiological fruit drop. So what causes young fruit to turn green slowly? What should be done? Let's take a look at the detailed introduction below.

I. Causes of slow greening

1. Rainy and cloudy weather with little sunshine

Under long periods of low temperature and rainy weather, the photosynthesis of the plant's leaves weakens, the nutrients formed are insufficient, and the tree body gradually weakens. After the plant sets fruit, it also needs a large amount of nutrients, so the phenomenon of nutrient supply falling short of demand appears, and the young fruit turns yellow. With too much water, the absorption capacity of the root system weakens, and coupled with less nutrient synthesized by photosynthesis, root growth is hindered, thus causing the young fruit to turn green slowly or with difficulty.

2. Hindered growth of new shoots

When the leaves of new shoots cannot turn green normally or the spring shoots are attacked by pests and diseases, the nutrients synthesized by their photosynthesis are less, unable to satisfy the growth and greening of the fruit, and it will also cause a large number of young fruits to fall off.

3. Hormone imbalance

During the growth of young fruit, if the plant's auxin and gibberellin are sown, the fruit stalk will produce abscisic acid and cause fruit drop, while the spring shoots do not turn green, the photosynthesis efficiency is low, causing fruit drop.

II. Solutions

Fruit thinning, pruning, drainage and irrigation, and pest and disease control should be carried out reasonably, especially paying attention to the matrix diseases that cause fruit drop, which are extremely likely to occur during rainy periods. Fertilization should be reasonable according to each growth stage of citrus, supplementing what is needed during the period. When there is less light, supplement organic fertilizer and growth regulators in time to promote photosynthesis, so that the nutrition is even, so as to avoid the phenomenon of slow greening. During the period of controlling shoots and promoting flowers in the plant, for weak tree bodies, girdling should not be too early or too heavy; hormones should be used as much as possible. For tree bodies with insufficient nutrition, measures of spraying foliar fertilizer can be increased to promote their growth.
