Embodiment 1

[0024] The low-concentration slow-release fertilizer special for sugarcane provided by the invention can be produced by small and medium-sized fertilizer enterprises according to the formula ratio.

[0025] The production of 1 ton of nitrogen, phosphorus and potassium content in the ratio of 15-8-5 low-concentration slow-release fertilizer for sugarcane requires raw material fertilizer: 318kg of urea with 46% N content; 2 o 5 41 kg of monoammonium phosphate with 49% N content and 9% N content; 2 o 5 333 kg of 18% calcium magnesium phosphate fertilizer; containing K 2 O content 60% potassium chloride 84 kg; filler 224 kg.

Embodiment 2

[0027] The low-concentration slow-release fertilizer special for sugarcane provided by the invention can be produced by small and medium-sized fertilizer enterprises according to the formula ratio.

[0028] The production of 1 ton of nitrogen, phosphorus, and potassium content in the ratio of 15-8-5 sugarcane special medium-concentration slow-release fertilizer requires raw material fertilizer: 322 kg of urea with a N content of 46%; 2 o 5 21 kg of monoammonium phosphate with 49% N content and 9% N content; 2 o 5 389 kg of calcium magnesium phosphate fertilizer with an amount of 18%; containing K 2 Potassium chloride with 60% O content is 84 kg; filling material is 184 kg.

Abstract

The invention relates to a special low-concentration slow release fertilizer for sugar cane. The nitrogen/phosphorus/potassium in the slow release fertilizer is 15:8:5. The invention can effectively the emergence rate, tillering rate and plant height of the sugar cane, and the test indicates that the emergence rate is enhanced by 0.9-1.7%, the tillering rate is enhanced by 2.3-4.2%, and the plant height is enhanced by 2.0-3.3cm; the slow release fertilizer can obviously enhance the agricultural yield of the sugar cane, and the test indicates that the unit yield of the sugar cane is enhanced by 0.8-1.5 t.hm<2>; the slow release fertilizer can obviously improve the quality of the sugar cane, and the test indicates that the field brix of the sugar cane is enhanced by 0.3-0.6% and the sucrose content is enhanced by 0.3-0.5%; and the invention reduces the number of times of fertilizer application, and lowers the labor cost. The special low-concentration slow release fertilizer for sugar cane is suitable to be applied to soil with medium sugar cane region fertilizers in tropical and subtropical zones in Southern China.

Description

Technical field: [0001] The invention relates to agricultural fertilizers, in particular to a special low-concentration slow-release fertilizer for sugarcane. Background technique [0002] Sugarcane is an important sugar crop in my country, which has the characteristics of long growth cycle, high production and large nutrient demand. During the entire production period of sugarcane, it is generally necessary to apply base fertilizer, seedling fertilizer, attack fertilizer, stem fertilizer and strong tail fertilizer to meet the nutrients needed for sugarcane growth. In modern sugarcane agriculture, artificial fertilization has become the most important measure for sugarcane production and high-yield and high-sugar cultivation. However, repeated fertilization is labor-intensive, time-consuming and labor-intensive, and has not adapted to the needs of modern sugarcane industry development. Slow-release fertilizer has become the direction of sustainable development of fertilize...
