Abstract

The invention discloses a suspension liquid set fertilizer for reducing yellowing of honey pomelo leaves and a preparation and application method thereof. The suspension liquid set fertilizer is composed of a suspension liquid fertilizer a and a suspension liquid fertilizer b; according to the suspension liquid fertilizer a and the suspension liquid fertilizer b, a phosphate fertilizer and calciumand magnesium fertilizers are separately prepared so that the phosphate fertilizer and other raw materials can be prevented from a drastic exothermic action, and the best use effect can be achieved.The set fertilizer can not only meet the nutrient requirements of fruit trees in different growth stages, but also obviously alleviate the yellowing symptom of the fruit trees; finally, the yield of the fruit trees is increased, the quality of the fruit trees is improved, and therefore the economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a suspended liquid set fertilizer for alleviating the yellowing of pomelo leaves and a preparation and application method thereof. Background technique [0002] Chlorosis, also known as "yellow leaf disease" and "chlorosis", is a disease condition in which the chlorophyll content is reduced and the leaves of the plant appear light green to yellow-green. Yellowing occurs in a wide range, and this phenomenon exists in 25% to 30% of the plants in the world's land area. The causes of yellowing are complex and are the result of the combined effects of many factors. In recent years, with the development of society, environmental pollution and the large-scale application of chemical fertilizers and pesticides have caused the ecological environment to continue to deteriorate. The area and degree of fruit tree yellowing have become more and more serious. On kiwi, apple, grape, peach...
