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

Special compound fertilizer for sugar cane

Technical field

The present invention relates to technical field of agricultural fertilizers, is a kind of special compound fertilizer for sugar cane specifically.

Background technology

Sugarcane is the main raw material of China's sugaring.In world's sugar ultimate production, sucrose accounts for 65%， China and accounts for more than 80%, and sugar is one of necessary edible product of the mankind, is also the important source material of the foodstuffs industry such as candy, beverage.Sugarcane is applicable to planting in fertile soil, sunny, the large place of summer in the winter temperature difference.Sugarcane is temperate zone and tropical farm crop, is the raw material of manufacturing sucrose, and can refines ethanol as energy substitution product.The whole world has more than 100 country to produce sugarcane, and maximum sugarcane production state is Brazil, India and China.

The normal growth of sugarcane has its rule to the needs of various nutrients, producing at present upper is the mixed fertilizer of compound ginseng of 25%～40% left and right to the fertilising major part of sugarcane, cannot meet the growth demand of sugarcane, one band in Guangxi particularly, soil is compared barrenr, and most of user fertilising is by habits fertilization, rather than apply fertilizers scientifically by the feeder capability of psychological need and soil, result cannot meet the growth demand of sugarcane, has restricted the normal growth of sugarcane, has affected the raising of sugarcane yield.

Summary of the invention

For breaking the bottleneck of resistance barrier sugarcane normal growth, according to sugarcane to the proportionlity between the requirement of various nutrients and nutrient thereof, feeder capability in conjunction with the most of red soil in Guangxi, a kind of sugarcane composite special fertilizer is provided, it can meet the demand of Guangxi sugarcane production to fertilizer, through practice for many years, obtained user's welcome and favorable comment.

For achieving the above object, the technical solution used in the present invention is: a kind of special compound fertilizer for sugar cane, N:P in described composite fertilizer ₂o ₅: K ₂0 ratio is 23～26:7～11:18～24.

Further, N:P in described composite fertilizer ₂o ₅: K ₂0 ratio is 24～25:8～10:19～23.

Further, N:P in described composite fertilizer ₂o ₅: K ₂0 ratio is 24:10:20.

Further, described composite fertilizer is comprised of urea, diammonium phosphate and Repone K.

Further, described composite fertilizer forms by following proportioning raw materials:

Urea 43～48% containing N amount 46%

Containing P ₂o ₅the diammonium phosphate 15～24% of amount 46% and N amount 18%

Containing K ₂the Repone K 32～38% of O amount 60%.

Urea 44.7% containing N amount 46%

Containing P ₂o ₅the diammonium phosphate 22% of amount 46% and N amount 18%

Containing K ₂the Repone K 33.3% of O amount 60%.

Application process: when product of the present invention is used, divide two stages to use, the first stage is as base manure, by every mu of 15kg, uses and can meet the early stage growth demand of sugarcane, topdress and use by every mu of 70-85kg whole the taking out for a long time of sugarcane, can meet the nutritional needs of sugarcane late growing stage.

Compare with existing fertilizer, useful technique effect of the present invention is:

1, product of the present invention, for the feature of Guangxi soil depletion, has increased soil N P ₂o ₅, K ₂0 content, can effectively overcome blindly fertilising and make the disadvantage that sugarcane yield is low, sugar part is low, benefit is not high, thereby improve sugarcane yield, increases the income level of peasant household, promotes the stable and development of Guangxi mainstay industry.

2, product of the present invention adopts two-part to use, the blindness fertilising custom that before changing, sugarcane grower falls behind, and the guiding sugarcane grower enthusiasm of the exhibition that inspires of depending on science and technology, thus improve constantly the Sugarcane Industry level of the productive forces.

3, product of the present invention obtains penetration and promotion in Guangxi province, uses product of the present invention and can improve sugarcane percentage of germination 10～20%, increases production 20～30%.

Embodiment

Below in conjunction with embodiment, the present invention is further illustrated;

Embodiment one

1,000 ten thousand mu in Guangxi soils of product of the present invention promote the use, in the situation that not increasing input, reducing labor force simultaneously, can increase production sugarcane 1000～1500 whole year more than ten thousand tons, by 450 yuan of calculating of sugarcane per ton, the gross income of peasant household reaches 45～67.5 hundred million yuan, can make sugarcane yield per unit area yield step on a new stage, and average yield per mu reaches more than 5 tons, than 3.5～4.5 tons of every mu of mean yields of original conventional fertilizers, output improves 20～30%.
