Problems solved by technology

However, the cost of this technology is high, and the organic solvent used in the production process will cause secondary pollution; patent CN107032858 A discloses a sugarcane fertilizer and a preparation method thereof. The fertilizer contains 16 kinds of materials, which causes extremely inconvenient production. It is also difficult to control the existing sugarcane fertilizer related patents without taking into account the relationship between economic benefits and environmental benefits

Abstract

The invention belongs to the field of crop cultivation, and relates to a special fertilizer for sugarcane and an application method thereof. The special fertilizer is prepared by uniformly mixing urease-inhibiting urea, zinc humic acid diammonium and potassium chloride, and two methods of base fertilizer application and topdressing application are used. The one-time application method can reduce the frequency of fertilization, reduce the labor of fertilization, and according to the nutrient absorption law of sugarcane, improve the nutrient distribution ratio, enhance the photosynthesis of sugarcane, reduce ammonia volatilization, and improve the utilization rate of fertilizer. It is safe, ecological, and low in cost. practical application value.

Description

technical field [0001] The invention belongs to the field of crop cultivation and relates to a special fertilizer, in particular to a special fertilizer for sugarcane and an application method thereof. Background technique [0002] Sugarcane is the main sugar crop in China. my country's sugarcane planting area ranks third in the world. The main production areas are in Hainan, Guangxi, Guangdong and other provinces. Sugarcane has become the main source of income for local farmers and is also an important energy crop. At present, my country's sugarcane planting is mainly based on soil cultivation of seedlings. The growth period of sugarcane is about 12 months, with high yield and large nutrient demand. Improper use of fertilizer during the planting process can easily cause seedling burn and soil quality degradation; if the amount of fertilizer is insufficient, sugarcane is prone to defertilization in the later stage, so how to ensure that the fertilizer will not cause damage t...
