Mango fertilization program, each of these four periods of fertilization must pay attention to

One, urge flower fertilizer.Mango flower bud differentiation is approximately between November and December, 15-20 kg of burning soil and 0.5-1 kg of compound fertilizer (such as a nitrate, etc.) should be applied to each tree from October to November to promote flower bud differentiation.
Two, strong flower fertilizer.The period from January to march is the period of bud development and flowering, and fast-acting nitrogen fertilizer (such as fecal water, urea, ammonium sulfate, etc.) can be applied to promote bud development and improve flowering and bearing rate.
Three, strong fruit fat.April to may is a period of rapid fruit growth, but also a period of slightly rapid growth in spring, when nutrient deficiency can cause a large number of fruit.Nitrogen and potassium fertilizer can be applied to balance the nutrient needs of shoot growth and fruit development.
Fertilization before and after mango picking.This period should apply heavy fertilizer, make the plant gets nutrient complement in time after picking fruit, pull out a bit in time, lay a foundation for next year's result, this apply fertilizer is given priority to with organic fertilizer, cooperate fast effect fertilizer.At this time, green manure exuberant, can be combined with deep turning hole, under the leaf curtain of each tree symmetrically dug two long 120 cm, wide 45 cm, deep 60 cm fertilization ditch, filled with green manure, mixed 15-20 kg barnyard manure or compost, 0.5-1 kg superphosphate calcium.When the tree is weak, add 0.5 kg of fast-acting nitrogen fertilizer (or a load of fecal water), so as to recover the tree potential and flower bud differentiation after fruit harvesting.
