Abstract

Farmyard manure and compound microorganism fertilizer are used as base fertilizer in the sugarcane seedling stage, and high-potassium compound fertilizer is combined with the compound microorganism fertilizer and leaf fertilizer special for sugarcane to serve as additional fertilizer in the sugarcane tillering stage and the elongation stage. The compound microbial fertilizer comprises the following raw materials in parts by weight; the fertilizer is prepared from the following components in parts by weight: 100-150 parts of molasses, 20-30 parts of distillers' grains, 10-30 parts of peanut meal, 30-50 parts of aquatic plants, 10-30 parts of fulvic acid, 5-10 parts of amino acid, 10-25 parts of monopotassium phosphate and 1-3 parts of a microbial agent. According to the method, the compound microbial fertilizer and the farmyard manure are spread to regulate soil and provide organic nutrients, the high-potassium compound fertilizer is combined with the compound microbial fertilizer and the leaf fertilizer special for the sugarcane in the tillering stage and the elongation stage of the sugarcane, and the nutrients and the fertilizer efficiency of the fertilizer can be improved; the sugarcane yellowing prevention and treatment effect is remarkable, the effect of treating symptoms and root causes is achieved, and the yield and quality of sugarcane are obviously improved.

Description

technical field [0001] The invention relates to the technical field of sugarcane planting, in particular to an aboveground and underground combined control method for sugarcane perennial root yellowing. Background technique [0002] Sugarcane is a temperate and tropical crop and an important sugar economic crop in southern my country. It is widely planted in Guangxi, Guangdong and Fujian. During the planting process of sugarcane, pests and diseases will seriously hinder the growth of sugarcane. Among them, sugarcane yellowing disease is a worldwide sugarcane disease that seriously endangers the growth of sugarcane. Resulting in reduced sugarcane yield and poor quality of sugarcane. Therefore, how to prevent and control sugarcane yellowing has important research significance for improving sugarcane yield and quality. [0003] Sugarcane yellowing is mainly divided into physiological yellowing and pathological yellowing. Physiological yellowing is caused by excessive nutrient...
