1. Strengthen tree nutrient accumulation and increase tree resistance.
What is the result of the inefficient flowering of litchi?
Before flowering, if fertilizing, apply only organic manure and phosphorus and potassium fertilizers, try not to apply nitrogen fertilizer, and apply organic liquid fertilizer after flowering to the leaves before flowering, such as plant nutrient regulator Yuhualing No. 2 -3 times.
2, short cut flowers spike
In March, the red flower buds and the gardenia will have their main spikes 10 centimeters long, with a short cut, leaving 4-5 lateral spikes, and a foliar spray of plant nutrient regulators to increase the photosynthetic efficiency of the leaves and promptly replenish the tree due to heading and flowering. Consumption of nutrients increases fruit setting rate.
3, after the shoot tipping
The shaded, intersecting and stronger growing branches at the top should be removed in time after the shoot period to balance the tree vigor and ensure the ventilation and light transmission of the trees to prevent the falling of flowers caused by excessive humidity in the trees. .
4, artificially sparse, ensure the fruit, regulate the production period
If it is necessary to postpone the flowering period, technical treatment shall be carried out immediately after the flowers are opened, so that the early flowers will fall off by 60%-70%, and later flowers will be induced into female flowers to promote fruit set. If it is necessary to ripen the fruits earlier, after the first batch of mother flowers have been pollinated and fertilized, the flowers will fall off later.
5, artificial pollination
When the anther was cracked, the pollen was collected with a wet towel, 10% sucrose, and 0.01% borax and sprayed on open female flowers within 30 minutes after harvesting.
6, shake the flowers in time after rain
When the female flowers are in high temperature and dry during the blooming period, they should be sprayed with water to increase the air humidity and promote pollination and fertilization.
