During scientific fertilization and fertilization, in addition to focusing on the coordinated application of a large number of elements such as nitrogen, phosphorus and potassium, attention should be paid to the proper supplementation of calcium, magnesium and zinc to ensure the normal supply of expanded fruit, and the leaves should be sprayed with strong fruit and new high-fat film in time. For the growth and development of fruit trees, it can play the multiple functions of internal meridian conditioning and outer skin protection, and reduce the occurrence of cracking, premature aging, sunburn and Other problems.
The abnormal weather conditions of the roots have caused serious damage to the citrus roots, and some root problems caused by fertilizers and diseases have been improved in time. Use appropriate fertilizers together with roots to help restore root growth, promote new roots, enhance fertilizer and water absorption capacity, and help to expand fruit.
Reasonable fruit thinning for trees with excessive fruiting, sparsely cut vegetative branches, shaded branches, diseased branches, etc., as well as pests, deformed fruits, cracked fruits, abnormal fruits, etc., the wounds caused by pruning should be painted in time. Anti-corrosion film protects the growth of wound healing tissue, infects the diseased bacteria from the wound, sprays the photosynthetic nutrient film fertilizer in time, and improves photosynthesis to ensure that there is enough nutrients to supply the fruit.
