1. Planting method of litchi seedlings
Seedling planting: when planting litchi trees, try to plant them in places with slopes, and the soil should be deep and fertile, with good drainage, rich in organic matter and slightly acidic soil. The time can be from early March to mid April in spring or from mid September to late October in autumn. Plant according to the amount of 18 to 20 trees per mu, and it is better to make the distance between each tree a little wider, which can be 6 * 6 or 7 * 7 meters. When planting, let the seedling expose about 15cm in the middle, and then fill it with enough water p>
Planting management: after planting seedlings, do a good job in water and fertilizer management and pest control. In terms of watering, because the root system of the seedling has not recovered after planting, it needs a certain time to recuperate, so its ability to absorb nutrition will be poor temporarily, so it needs to be watered in time to prevent drought. Generally, a small amount of fecal water can be applied only half a year after the plants are colonized and survive. When the fruit trees survive for two years, the use of fertilizer can be increased. Generally, the fertilizer is applied four times a year, and the fertilizer containing specific elements is applied during each season change, combined with the different growth conditions of fruit trees p>
Shoot control pruning: before fertilizing the fruit tree, cut off the damaged and diseased branches, and control the height of each plant below two meters, so as to maintain the transmission of nutrition. It should be noted that due to different varieties of litchi, there will be some differences in flowering rate. Those with small flowering rate should be thinly cut and a small amount of short cutting p>
Pest control: the common pests of litchi are mainly beetles. You can spray insecticides on the fruit trees around April every year, once every six days, and use the 1000 times liquid of litchongjing and 1000 to 2000 times liquid of anlubao alternately. When picking litchi in the later stage, pay attention to the safety period of pesticides on fruit trees p>
