Longan fertilization and time
Longan, also known as longan, has a variety of functions such as tonifying the heart and spleen, nourishing blood and calming the mind and longevity, and is favored by foodies. When planting longan, the quality and yield of fertilizer play a very important role. The following will introduce the fertilization method and time of longan in detail.
1. Young trees
In general, young trees should be fertilized a small amount for many times, and thin fertilizer should be applied lightly. The newly planted longan seedlings can be fertilized after the new shoots are enriched, and thin human feces and urine are the best, and the dilute urea solution can also be applied 2 to 3 times a month. With the growth of the plant, the concentration and fertilizer application amount should be applied before each extraction. Organic fertilizer should be applied once before spring shoot germination, nitrogen fertilizer should be increased before autumn shoot germination, phosphorus and potassium fertilizer should be increased after autumn shoot filling, and the proportion of nitrogen fertilizer should be reduced. The development of young trees was dominated by nitrogen fertilizer in the first few years, and the proportion of phosphorus and potassium fertilizer was increased appropriately in the later years.
2. Adult trees
The purpose of fertilization for adult longan trees is to increase yield, restore tree potential and prolong the peak fruiting period. The general principle is that weak trees should apply more diligently, and prosperous trees should apply fertilizer according to the growth situation, especially according to the results of nutrition diagnosis. In the process of growth and development of longan, fertilizer is applied at least three times according to the three periods of autumn shoot growth and development, flower bud differentiation induction and fruit growth and development. However, in production practice, fertilizer can also be applied five times a year according to the peak of fertilizer demand, which are pre-flowering fertilizer, flower-protecting fertilizer, fruit-protecting fertilizer, strong fruit fertilizer and fruit-picking fertilizer, respectively.
If you want longan to grow big and sweet, fertilization is the key. You can manage it according to these fertilization methods.
