Problems solved by technology

[0003] The normal growth of sugarcane has its own rules for the needs of various nutrients. At present, most of the fertilization of sugarcane in production is about 25% to 40% compound ginseng and mixed fertilizer, which cannot meet the growth needs of sugarcane, especially in the In Guangxi, the soil is relatively barren. Most users fertilize according to their habits, rather than scientific fertilization according to physiological needs and soil fertilizer supply capacity. As a result, they cannot meet the growth needs of sugarcane, which restricts the normal growth of sugarcane and affects Increased sugar cane yield

Embodiment 1

[0024] The product of the present invention is popularized and used in 10 million mu of land in Guangxi. Without increasing investment and reducing labor force, the annual production of sugarcane can be increased by more than 10-15 million tons. Calculated at 450 yuan per ton of sugarcane, the total income of farmers will reach 45. ~6.75 billion yuan, which can bring the yield of sugarcane to a new level, with an average yield of more than 5 tons per mu, which is 20-30% higher than the average yield of traditional fertilizers of 3.5-4.5 tons per mu.

Embodiment 2

[0026] The experiment consisted of 2 test groups and 1 control group

[0027] Test group 1: Prepared by mixing the raw materials according to the following weight ratio, 44.7% urea containing 46% N, 44.7% containing P 2 o 5 Diammonium phosphate 22% and K containing 46% and 18% N 2 Potassium chloride 33.3% of O content 60%. Then 15% is used as base fertilizer, and the rest is used as top dressing during the sugarcane elongation period. The germination rate of sugarcane is 95%, and the yield per mu is 5 tons.

[0028] Test group 2: Prepared by mixing the raw materials according to the following weight ratio, 43% urea containing 46% N, 43% containing P 2 o 5 Diammonium phosphate 20% and K containing 46% and 18% N 2 Potassium chloride 37% with 60% O content, then 15% is applied as base fertilizer, and the rest is applied as top dressing during the sugarcane elongation period. The germination rate of sugarcane is 96%, and the yield per mu is 5.1 tons.

[0029] Control group:...

Embodiment 3

[0032] Each raw material is mixed and prepared according to the following weight ratio, 48% of urea containing 46% of N content, 48% of urea containing P 2 o 5 Diammonium phosphate 15% and K containing 46% and 18% N 2 Potassium chloride 37% with 60% O content; N:P in compound fertilizer 2 o 5 :K 2 The ratio of O is 26:7:22.

Abstract

The invention relates to the technical field of agricultural fertilizers, in particular to a special compound fertilizer for sugarcane. The ratio of N to P2O5 to K20 in the compound fertilizer is (23-26) to (7-11) to (18-24). According to the compound fertilizer, aiming at the characteristic of poor soil in Guangxi, the contents of N, P2O5 and K20 in soil are increased, and the defects of low sugarcane yield, low sugar content and low benefit due to blind fertilization can be effectively overcome, so that the sugarcane yield is increased, the income level of sugarcane farmers is increased, and the stability and development of Guangxi pillar industry are promoted; the fertilizer is applied in a two-section manner, so that the out-dated production habits of the farmers in the past is changed, the enthusiasm of the sugarcane farmers in promoting development by science and technology is guided, and the productivity level of sucrose industry is continuously increased.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special compound fertilizer for sugarcane. Background technique [0002] Sugarcane is the main raw material for sugar production in my country. In the world's total sugar production, sucrose accounts for about 65%, and our country accounts for more than 80%. Sugar is one of the necessary food for human beings, and it is also an important raw material for food industries such as candy and beverages. Sugarcane is suitable for planting in places with fertile soil, sufficient sunlight, and large temperature differences between winter and summer. Sugar cane is a temperate and tropical crop that is used as a raw material for the manufacture of sugar and for ethanol as an energy substitute. There are more than 100 countries producing sugar cane in the world, and the largest sugar cane producing countries are Brazil, India and China. [0003] The normal growth of su...
