Lychee is also called Lizhi. Because of its rich sweetness and rich nutritional value, it has the functions of thirst, thirst, spleen and beauty, and it has the title of “king of the fruitâ€, so it has become very popular in the market. One of the welcome fruits, many growers also want to plant, then Xiaobian will introduce you to the high-yield planting techniques and fertilization techniques of litchi:
I. Orchard planting
First, the litchi orchard can be selected in a place with slopes, depending on the situation. The size is usually 3-4 mu. The cultivation time of litchi is suitable in early spring and early autumn, which is mid-March and early October. There are about 19 plants per mu. Left and right, because the height of the lychee will reach 1-2 meters, so the line spacing between each plant should be as wide as possible, 5*5 meters or 6*6 meters is better, and the lychee seed is exposed in the middle 15 cm or so. Do not use your feet or hammer with water to pump enough water, about 50 kg per plant.
Second, fertilization measures
Litchi needs to be fertilized 3-4 times a year. Each season of the season needs to apply fertilizer once. The base fertilizer per mu needs to use about 1500 kg of decomposed farmyard manure, and Sanan is about 45 kg. After each leaf turns green, it can be sprayed. Foliar fertilizer such as phosphate fertilizer superphosphate, 10 kg of high-phosphorus water soluble fertilizer can be applied per acre before the flower bud begins to differentiate, and high-potassium water soluble fertilizer can be applied before physiological fruit drop, in order to supplement the tree body after fruit picking Nutrients can be applied to balanced water-soluble fertilizers. In the topdressing, you should only grasp the amount and do not apply fertilizer at will.
Third, control tip trimming
Before the fertilization, some injured branches and branches affected by pests and diseases will be pruned. The height of each plant should be controlled below two meters to maintain the nutrient transmission and height of the tree. However, when pruning, pay attention to the different varieties of litchi. The effect with flower buds is small, and the flowering rate is still high in the next year, but other varieties may affect the flowering rate. The effects of lychee products such as March red will be greater, and the flowering rate will decrease in the next year, so it should be thinned. And a small amount of short cuts.
Fourth, pest control
The main pests of litchi are chafers. Because pests have a great influence on the quality and yield of litchi, it is necessary to prepare for the litchi according to the situation of litchi. Generally, the first insecticide is sprayed around April, and sprayed every 6 days or so. It is interspersed with aphid net 1000 times liquid and Anlubao 1000--2000 times liquid. When picking litchi, pay attention to the safety period of the pesticide on the tree.
In addition, the pests have a great influence on the growth of litchi, so it is found that this situation must be dealt with in a timely manner. Although litchi may be more energetic and costly in the early stage, the litchi can repeat the results and pass the cost of the first stage of the results. Smaller and higher profits, it is a very feasible planting project, but the most important thing to pay attention to during the lychee planting process is the situation of pests and diseases.
