Embodiment 1

[0007] Example 1: The production of 1 ton of compound fertilizer requires 217 kg of raw material fertilizer urea, 625 kg of superphosphate, 96 kg of potassium sulfate, and 62 kg of filler.

Embodiment 2

[0008] Example 2: The production of 1 ton of compound fertilizer requires 217 kg of raw material fertilizer urea, 625 kg of superphosphate, 89 kg of potassium chloride, and 69 kg of filler.

[0009] Application of base fertilizer: when sugarcane is planted, 10:10:5 compound fertilizer is applied at 40-60kg / mu in the planting ditch of sugarcane.

[0010] Application of topdressing fertilizer: In the large growth period of sugarcane combined with cultivating soil, apply 10:10:5 compound fertilizer at 40-60kg / mu and add 20-40kg of urea to the vicinity of the root system of sugarcane, and at the same time cultivate the sugarcane , to ensure that the fertilizer is covered with soil.

[0011] Experiments show that the application of 10:10:5 special compound fertilizer for sugarcane as base fertilizer can effectively increase the emergence rate and tillering rate of sugarcane, and combined with topdressing fertilizer application can increase the stem formation rate of sugarcane, and ...

Abstract

The present invention relates to a special fertilizer for sugar canes. According to the weight portions, the complex fertilizer contains 21.7 portions of urea, 62.5 portions of calcium superphosphate, 9.6 portions of potassium sulfate or 8.9 portions of potassium chloride, and 6.2 to 6.9 portions of filler. In the formula, the fertilizer contains 10 percent of N, 10 percent of P2O5 and 5 percent of K2O. The filler is made by mixing filter mud and clay according to the ratio of 7 to 3. The fertilizer is a compound fertilizer containing nitrogen, phosphor and potassium, and can fundamentally solve the problems of nutrient balance, output and low sugar in the production of the sugar canes. At the same time, when the common type compound fertilizer special for sugar canes is used, a certain amount of straight fertilizer can be added to be used not only as a ground fertilizer but also as a dressing fertilizer. And the straight fertilizer can greatly facilitate the production, packaging and application of fertilizers, so as to reduce the cost of the production, the packaging and the transportation of the fertilizers.

Description

Technical field: [0001] The invention relates to a special fertilizer for sugarcane. Background technique: [0002] Sugarcane is an important sugar crop in my country. It has a long growth cycle, requires a large amount of fertilizer, and requires a variety of fertilizers. This is in contradiction to the fact that it only pays attention to the application of a single fertilizer and the unreasonable ratio of nitrogen, phosphorus, and potassium in production. Single fertilizer Excessive application of sugarcane resulted in low yield and sugar content of sugarcane in sugarcane areas. Due to the influence of many factors such as sugarcane farmers' fertilization habits, economic conditions, and backward fertilizer production technology in sugar factories, Invention content: [0003] The purpose of the present invention is to propose a special fertilizer for sugarcane, which is a ternary compound fertilizer containing nitrogen, phosphorus and potassium, which can fundamentally so...
