The solution to the flourishing growth of litchi without flowering

Litchi is an important economic fruit tree, which has a wide planting area in China, but it will flourish and not blossom during planting, which seriously affects the flower bud differentiation and even no harvest of litchi. So how to solve it? Let's take a look at the detailed introduction.

1. Lack of light

If each kind of plant wants to grow normally, it must be in a temperature environment that is suitable for its own growth. The higher the temperature in this environment, the faster its growth will be. However, in the case of insufficient light, the higher the temperature, the weaker the growth, which is not conducive to the later yield.

Solution: for the prosperous growth caused by this situation, it is necessary to control the temperature and increase the light to make it grow normally.

2. Too much water

Moisture and humidity are also indispensable for growth, they can synthesize gibberellin in plants, but too high gibberellin content will cause cytoplasmic expansion and elongation, resulting in vigorous growth. Especially when litchi grows slightly in winter, it will cause exuberant leaf growth and delay flowering and fruiting.

Solution: to manage water reasonably, drainage measures should be taken in the rainy summer season to maintain appropriate soil moisture, but not long-term drought, water consumption should be determined according to litchi varieties and local conditions.

3. Uneven fertilization.

Nitrogen fertilizer plays an important role in promoting plant growth, and many fruit growers often apply a large amount of nitrogen fertilizer in order to accelerate the growth of litchi plants, but once the proportion of nitrogen fertilizer in the soil is too high, the root system is blocked from absorbing other nutrients, it will flourish and grow, thus affecting the normal flowering and fruiting.

Solution: in the fertilization should be reasonable, more organic fertilizer, improper fertilization caused by prosperity, can be sprayed with low concentration of potassium dihydrogen phosphate to control growth.

4. Chemical control

Litchi prosperous growth will bring some harm, light will reduce production, heavy will be no harvest, so in planting management can use chemicals to control growth. The common growth retarders are paclobutrazol, dwarf, methylpiperonium, anti-inverted fat and so on. Spraying them on leaves can inhibit the expansion and elongation of cytoplasm and achieve the effect of inhibiting growth. There are also common growth promoters such as ethephon, abscisic acid and adrenaline, which can inhibit indole acetic acid auxin in plants and achieve short-term growth inhibition effect.

The above is the introduction of the solution to the non-flowering of litchi. I hope it can help you. If you want to know more about it, please follow us.
