Last Updated: 2024/11/24, Friends who plant fruit trees all know that the bad flower bud differentiation determines the yield and quality of fruit trees, so attention must be paid to the flower bud differentiation of fruit trees. Litchi is familiar to us. Its economic value is very high. If we want to achieve high yield, we need to differentiate from flower buds.

Friends who plant fruit trees all know that the bad flower bud differentiation determines the yield and quality of fruit trees, so attention must be paid to the flower bud differentiation of fruit trees. We are familiar with litchi, its economic value is very high, in order to achieve high yield, we need to start from flower bud differentiation, then what conditions do litchi flower bud differentiation need? Let's take a look.

1. The time of flower bud differentiation

First of all, it is necessary to understand the time of flower bud differentiation. Litchi flower bud differentiation varies with quality and region. In general, early maturity varieties begin flower bud differentiation in autumn in October, while middle and late maturity varieties begin flower bud differentiation in December. Other varieties begin to differentiate into flower buds in December and will continue to match in March of the following year.

2. Nutrient demand

Litchi fruit branch growth is robust, tree potential is moderate, easy to control winter, accumulate enough nutrients, which is conducive to plant flower bud differentiation. The more nutrients the tree accumulates, the better its flower bud differentiation will be. if the tree is too vigorous, the vegetative growth of the plant is exuberant, which is not conducive to its flower bud differentiation, it is very easy to sprout flowers, pods and leaves ahead of time, which will lead to a reduction in yield; or the panicle is too long, nutrition consumption is too much, and the proportion of female flowers is less, which will also lead to a reduction in yield.

3. Temperature requirement

When litchi moves from vegetative growth to reproductive growth, the type and proportion of nutrients and hormones will change significantly, so as to meet the needs of plant reproductive growth. In litchi flower bud differentiation will secrete a large number of cytokinins, promote flower bud differentiation, low temperature in winter, low temperature for a long time, will inhibit plant vegetative growth, promote reproductive growth, so the quality of flower bud differentiation is good. If the winter temperature is high and the vegetative growth is exuberant, it will consume a lot of nutrients, the quality of flower bud differentiation is poor, and the quality and yield will also decline. The temperature requirements of different varieties during the day, the most common requirements of white wax and black leaves are as early as 8-15 degrees, while those of Feizixiao and white sugar are less than 20 degrees.

The above is the introduction of litchi flower bud differentiation conditions, hope to help you, want to know more related knowledge, please follow us.
