The latest planting method of Litchi

Litchi is loved by many people as a kind of fruit which is very sweet, pulp and moisture. But I'm afraid many people don't know that it takes a long time for litchi to grow like an apple tree. Litchi trees, like apple trees, are very tall and can bear fruit repeatedly. The following will explain the planting method of litchi for you.

1. Orchard planting

Litchi orchard can be selected where there is a slope, the size depends on the situation, the general size is 3-4 mu. The best time for litchi cultivation is in early spring and the Beginning of Autumn, that is, mid-March and early October, about 19 plants per mu. Because the height of litchi will reach 1-2 meters when growing up, the row spacing between each plant should be as wide as possible, 5-5 meters or 6-6 meters. Litchi seedlings are exposed about 15 cm in the middle. Do not tread with your feet or hammering with things during cultivation. You should irrigate enough water, about 50 jin per plant.

2. Fertilization measures

Litchi needs to be fertilized 3-4 times a year, and once in each changing season. The base fertilizer per mu needs to be about 1500 kg of mature farm manure and 45 kg of San'an. Every time the leaves turn green, you can spray some foliar fertilizers such as phosphate fertilizer, calcium superphosphate and so on. Half a month before flower bud differentiation, 10 jin of high-phosphorus water-soluble fertilizer can be applied per mu, high-potassium water-soluble fertilizer can be applied before physiological fruit drop, and balanced water-soluble fertilizer can be applied to supplement tree nutrients after fruit harvest. In topdressing, you should only grasp the amount, not fertilize at will.

3. Control pruning

Prune off some injured branches that have been damaged by diseases and insect pests before fertilizing. The height of each plant should be controlled below two meters to maintain the nutrient transfer and height of the tree. But when pruning, it should be noted that due to the different varieties of litchi, the influence of jade purse is small, and the flowering rate is still high in the following year. However, other varieties may affect the flowering rate, such as March Hong and other litchi products will have a greater impact, the flowering rate will be reduced the following year. So it should be thinly cut with a small amount of short cuts.

4. Disease and pest control

The main pests of litchi are beetles, etc. The pests have a great influence on the quality and yield of litchi. Preventive preparations should be made according to the situation of litchi. Generally, the first insecticide is sprayed around April, once every 6 days or so. It is interspersed with 1000 times liquid of Lizongjing and 1000 times liquid of an Lubao 1000Mui 2000 times. When picking litchi, attention should be paid to the safe period of pesticides on the trees. Diseases and pests have a great impact on the growth of litchi. We must observe this carefully, and if we find this situation, we must deal with it in a timely manner!

Although litchi may invest more energy and higher cost in the early stage, litchi can repeat the fruit. after the first fruiting period, the cost becomes smaller and the profit becomes higher, which is a very feasible planting project. in the process of litchi planting, we need to pay most attention to the two situations of diseases, pests and common diseases. if you want to know how to get rid of insects and diseases, the pro-agriculture network will continue to answer for you.
