Problems solved by technology

However, the existing mango fertilization technology mainly has the following problems: the time of fertilization is greatly affected by precipitation, and the nutrient absorption characteristics of the tree body are difficult to match with the best fertilizer efficiency; Fertilizer intake is obviously lacking; chemical fertilizer resources are wasted, nutrients are easily fixed by the soil and remain in the soil, severe leaching, nutrient availability is reduced, and fertilizer utilization rate needs to be improved
In addition, the single and unbalanced fertilization structure throughout the year can easily lead to aggravated soil continuous cropping obstacles, obvious symptoms of nutrient deficiency, decreased resistance of the soil ecosystem, and prominent health problems. Poor and other deficiencies

Abstract

The present invention provides a combined fertilization method suitable for mangoes in the whole growth period of fertilizer saving and efficiency enhancement. During the growth period of mangoes, mangoes are respectively applied with shooting shoot fertilizer, flower promoting fertilizer and fruit expanding fertilizer according to the three physiological stages of mango shoot shooting, flowering and fruiting; Shooting fertilizers are slow-release fertilizers with an effective content of nitrogen, phosphorus and potassium of 9-11%, 3-5% and 5-7%; flower-promoting fertilizers include organic fertilizers with an organic matter content of ~9%, 3~5% and 7~9% of slow-release fertilizer and borax; expanded fruit fertilizer includes slow-release fertilizer and calcium with effective content ratio of nitrogen, phosphorus and potassium of 7~9%, 3~5% and 7~9% The magnesium content ratio is 9-11%, 0.5-1.5% medium-element water-soluble fertilizer; the present invention not only significantly improves the yield and quality of fruits, but also fully improves the utilization rate of fertilizers, has a good effect of saving fertilizer and increasing efficiency, and realizes The expected effect of high yield and high quality of mango fruit, as well as the efficient and resourceful utilization of nutrients.

Description

technical field [0001] The invention relates to the technical field of mango fertilization, in particular to a combined fertilization method in the whole growth period which is suitable for mango to save fertilizer and increase efficiency. Background technique [0002] Known as the "King of Tropical Fruits", mango is a promising fruit tree in tropical and subtropical regions of my country, and its industry has become one of the main ways for farmers in tropical regions to increase production and income. Fertilization is an essential part of mango growth. Fertilizers play an important role in promoting the healthy growth of mangoes, improving the quality and yield of mangoes. However, the existing mango fertilization technology mainly has the following problems: the fertilization time is greatly affected by precipitation, and the nutrient absorption characteristics of the tree body are difficult to match with the best fertilizer efficiency; The intake of fertilizers is obvio...
