The quality of longan fruit is the key. How to improve the quality of longan fruit?

All aspects of quality are still very primitive. It is called soil longan in our country. Litchi and loquat, for example, are small in size, big in kernel, less in meat and poor in taste. Generally speaking, soil longan is more fragrant and resistant than longan on the market. Longan also has a name called nanguoshen. Medicinal longan meat is sweet. Southerners never doubt this certainty. Whether it is a native tree or a grafted tree, whether it is a native variety or an exotic variety, the sweetness of the pulp seems to be innate. If it is not sweet, it must be related to the growing soil and water.

The reason why longan is short may be the problem of planting management, for example, the plants are too close or not trimmed in time, or the fertilization or weeding is not timely. All these reasons may lead to small and reasonable close planting of fruits, which can not only keep the longan orchard ventilated and transparent, but also reduce pests and diseases, effectively improve the utilization rate of light energy, ensure the good growth of plants and fruits, and significantly improve the yield and quality of longan. The planting distance must be different according to the variety.

Whether the fruit is sweet or not is related to sunshine and water supply. Longan is sweet or not, just like apples and peaches. Sunshine will be sweeter and backlight will be tasteless. According to the planting characteristics of longan, the expansion of longan lasts until maturity, and the accumulation of sugar in fruit is nutritionally related to potassium. In addition, the variety and illumination time will also affect the sweetness of fruit. Nutritional and effective potassium supplementation can improve the permeability of cell membrane and promote the transformation of sugar.

Variety selection The selection of cultivated varieties mainly depends on market demand, adaptability of varieties in cultivation areas and cultivation technology level. At present, the main fine varieties cultivated in our city are: Chuliang, Shijie, Gushan No.2 and Shuang Mu.

Longan can be picked when it matures in July and August, but its seed life is short. After removing the pulp, remove the aril from the seed and you can sow! When seeds germinate, pay attention to temperature control, and it is best to cultivate seedlings in greenhouse. Temperature and humidity are best grasped.
