Problems solved by technology

[0005] ② A large amount of fertilizer is applied, but it is rarely absorbed and utilized by sugarcane. The waste of fertilizer is serious and the ecological environment is polluted
[0006] ③ Long-term use of chemical fertilizers will intensify soil acidification, resulting in soil compaction and structural deterioration
[0007] Fertilizer production technology is backward. It only adjusts and mixes the ratio of nitrogen, phosphorus and potassium, instead of improving the fertilizer from the perspective of how to improve the absorption and utilization of plants, resulting in low fertilizer utilization and serious losses.

Abstract

The invention discloses a sugarcane fertilizer additive, which comprises the following raw materials: 6-10 parts by weight of trace elements; 6-18 parts by weight of humic acid chelated rare earth; 3-6 parts by weight of slow-release agent ; 4-6 parts by weight of water-retaining agent; 8-15 parts by weight of organic matter. The production method is as follows: firstly, humic acid and rare earth chloride or rare earth oxide are used for chelation reaction to prepare humic acid chelated rare earth, and then various materials are added, mixed uniformly, dried and pulverized. The fertilizer additive of the present invention is mixed evenly with chemical fertilizers and applied; the general addition amount is 5-7%; the addition amount in sugarcane base fertilizer is 5%, and the addition amount in sugarcane topdressing fertilizer is 7%. The fertilizer additive of the invention can improve the utilization rate of sugarcane to chemical fertilizers, increase the plant height and stem diameter of sugarcane, and increase the yield.

Description

technical field [0001] The present invention relates to a fertilizer additive, especially a fertilizer additive for sugarcane, and to a production method thereof. Background technique [0002] Sugarcane is the most important sugar crop in my country. In 2010, the planting area of ​​sugarcane in my country was 1.602 million hectares, accounting for more than 85% of the perennial sugar crop planting area in my country, and the sugar production accounted for more than 90% of the total sugar production. The sugarcane industry is an important pillar of the economic development of the main producing areas in southern my country and the main source of farmers' income. Guangxi is located in the south subtropical zone, and its climate and soil conditions are very suitable for sugarcane production. It is one of the most suitable regions for the development of sugarcane sugar industry in the world, and it is the largest sugar-producing province (region) in the country. In the 2011 / 201...
