Xiaobian thinks that the high-yield of litchi is inseparable from the irrigation of fertilizer(black plastic nursery pots), and mastering scientific fertilization technology is of great help to improve the economic benefits of litchi. It is determined that if 1000 kg fresh litchi fruit is harvested(15 cell propagation trays wholesale), it will absorb about 1.35-1.88 kg of nitrogen (n), 0.31-0.49 kg of phosphorus (P2O5) and 2.08-2.52 kg of potassium (K2O) from the soil.

The growth and development of the fruit is mainly from pollination to fruit maturity(wholesale plant pots). The proportion of N, P and K demand is the same as that of the previous period. The fertilization of litchi trees should be flexibly controlled according to the climate, soil quality, variety, age, tree potential(21 cell propagation trays wholesale), fruit yield, shoot growth and control, so as to strive for a good harvest of fruits in the current year and consider the high yield in the next year.(cheap 9cm square plastic plant pots manufacturer)
How to plant delicious, high-quality and high-yield litchi is what every grower is looking forward to(plastic seed trays). Heavy application of base fertilizer can promote the timely germination of autumn shoots. For late maturing varieties, trees with more fruits, weak trees, old trees or bearing trees of suitable age, apply fertilizer 10-15 days before fruit picking(32 cell propagation trays wholesale). Generally, 2000-3000 kg of rotten organic fertilizer, 40-60 kg of general-purpose compound fertilizer or 1-1.5 kg of compound fertilizer are applied per mu of furrow or hole.
But this time, it is mainly in 10-20 days in January, which can be advanced or delayed according to different varieties(15 gallon nursery pots wholesale). In particular, the flower branches, flowers and male and female peanuts grow from the time when the flower spike is pulled out to the time when the flower withers, and the proportion of P and K increases(50 cell propagation trays wholesale). For the trees with strong early maturity and few fruit bearing, the young and strong trees can apply fertilizer from half a month to one month after fruit picking.
(cheap 9cm square plastic plant pots manufacturer)The early and middle maturing varieties should be applied before and after the "slight cold" in the first ten days of January(plastic nursery pots), and the late maturing varieties should be applied before and after the "great cold" in the last ten days of January. In this period, 0.3% - 0.5% urea or 0.2% potassium dihydrogen phosphate can be sprayed on the leaves(98 cell propagation trays wholesale), which will play an important role in strengthening fruit and reducing fruit falling.
To supplement the nutrient consumption caused by flowering and fruit setting to promote fruit development(1 gallon nursery pots bulk), topdressing should be carried out after flowering and before the second physiological fruit falling (April to May). That is to say, the early maturing species were applied in the first ten days of April, and the late maturing species were applied before and after the last ten days of May(105 cell propagation trays wholesale). Generally, high-N and high-k compound fertilizer is applied, 1.5-2kg per plant.
It can protect and strengthen the fruit, reduce the second physiological drop and improve the quality of the fruit(20 gallon nursery pots wholesale). Promote the recovery of trees and the development of autumn shoots, and lay a foundation for the next year's high yield. It is suggested that the early maturing and strong trees should be applied after fruit picking(128 cell propagation trays wholesale), and the late maturing, fruiting and weak trees should be applied 10-15 days before fruit picking.(cheap 9cm square plastic plant pots manufacturer)
Fertilization is mainly based on P and K fertilizer(plug trays), 30-40 kg of general-purpose compound fertilizer or high-k compound fertilizer or 0.5-1 kg of each plant are applied per mu, and urea or high-N compound fertilizer is not suitable to avoid "shoot flushing". Organic fertilizer and chemical fertilizer should be applied together(162 cell propagation trays wholesale). Each plant should be applied with 50-100 kg of mature high-quality organic fertilizer and 1-1.5 kg of general compound fertilizer (1:1:1).
