When does longan usually mature and appear on the market? How to plant in order to achieve high yield?

Longan is one of the most widely planted fruits from southwest to southeast of China, also known as longan, three feet of agricultural flavor, Yizhi, is a kind of nutritious fruit suitable for both young and old. So when does it usually mature and go on sale? How to plant in order to achieve high yield?

First, when does longan usually mature and appear on the market?

Longan is widely cultivated in the southwest to southeast of China, with Guangdong being the most popular, Fujian taking the second place, and partly planted in Hainan. Due to local climate, weather differences, so longan mature listing time is also a little different.

1. The listing time of longan in Guangdong is usually from July to October every year, in which the maturity of longan in Shenzhen is from mid-July to late August, and the maturity of Shixia longan in Guangdong Pearl River Delta is in early and mid-August.

two。 The mature time of longan in Fujian is from late July to late August, and that of Fuyan in Jinjiang, Nanan and Quanzhou is from late August to early September.

3. The mature market time of longan in Hainan is from March to July.

Second, how can longan be planted with high yield?

Longan generally uses seed propagation to cultivate rootstock seedlings, and then uses grafting to propagate. In addition to seedlings and planting conditions, the planting method is also a very important factor affecting longan's high yield, so the high-yield planting methods are sorted out as follows:

1. Grafting of longan seedlings

Longan is the seed collected from the mother tree with strong adaptability and few diseases and insect pests in July and August, sown immediately after harvest, and grafted in spring (April-June) or autumn (9-10) after 1-2 years of cultivation, either by bud patch or tongue grafting.

two。 Planting of longan saplings

The best planting time of longan seedlings is in spring and autumn, which is planted in rectangle or square. There are about 2600 longan saplings per hectare with a row spacing of about 4 meters. In addition, longan trees are best planted in the leeward, where the soil is fertile, loose and deep.

3. Fertilization Management of Longan seedlings

Longan tree planting, in addition to ploughing the soil with a certain amount of farm manure as base fertilizer, some river mud, field soil, burning soil, as well as some mature farm manure, superphosphate and plant ash can be put before planting. In addition, from late February to early March of the first year, it is necessary to apply mature dilute water fertilizer and potassium sulfate, and then apply some strong flower fertilizer from late March to early April. To mid-May to early June, according to the number of hanging fruit, but also apply strong fruit fertilizer; others also rent and apply a certain amount of foliar fertilizer.

4. Watering management of longan seedlings

Longan seedlings are watered 1-2 times a day after planting, and the times of watering should be reduced in the season with more precipitation. If there is too much water, timely drainage measures should be taken.

5. Pruning and pest control of longan trees

Longan tree pruning is based on the spring and autumn season, cutting off over-dense branches, withered old branches, disease and insect branches and overgrown branches. In addition, flower thinning will be carried out in mid-March, and fruits and vegetables will be carried out from late May to early June. During the period of planting management, it is necessary to prevent and control the occurrence of bald branch disease and stink bugs, and use different agents according to different conditions.

In the disease control of longan seedlings, we should give priority to biological control, so it is very good to protect the environment and develop pollution-free fruits, and it can also improve the economic value of longan, which can be said to kill two birds with one stone.
