How to apply mango blossom early fertilizer

Due to the dry weather and high temperature in winter, mango trees often produce flower buds early, ear early and form early flowers. Early flowering mango trees have long panicles, large number of flowers, consume a lot of nutrients, bloom early, and are easily affected by low temperature, overcast and rainy weather, resulting in poor pollination and fertilization, and finally low fruit setting rate. If early re-application of strong flower fertilizer can improve the nutrition level of early flowering mango trees, promote strong tree potential, and enhance the ability of flower ears to resist low temperature, overcast and rainy weather, the early flowering mango trees can be pollinated and fertilized normally and the fruit setting rate can be increased. The specific fertilization methods are as follows: in winter and spring, we should pay attention to observe the autumn shoots of mango trees. When we find that the top of autumn shoots sprout in front of "the Beginning of Spring", we should immediately apply strong flower fertilizer, mainly high-quality organic fertilizer and complete nitrogen, phosphorus and potassium fertilizer. at the same time, appropriate supplement of phosphorus and potassium fertilizer, fruit trees more than 5 years old, each tree retting 45kg of mature human and animal manure Nitrogen, phosphorus and potassium (15-15-15) compound fertilizer 1.5 kg, calcium superphosphate or calcium magnesium phosphate fertilizer 3 kg, potassium chloride or potassium sulfate 1 kg 1.5 kg. The specific fertilization method is to dig 6 or 8 radiation ditches with a depth of 15 cm 20 cm, a width of 25 cm 30 cm and a length of 80 cm 100 cm on the topsoil under the canopy. All the fertilizers are fully stirred and mixed evenly, sprinkled in the radiation ditch and covered with soil. In addition, 0.1% borax, 0.1% magnesium sulfate, 0.2% urea, 0.2% potassium dihydrogen phosphate and 800 times nucleotide active liquid fertilizer mixture should be sprayed every 10 to 15 days for 3 times in a row to wet all branches, leaves and flower buds inside and outside the crown evenly, so as to start dripping water, replenish nutrients from the leaves, improve the nutrition level of the plant, and help to promote strong flower ears.
