Special planting fertilizer for rubber trees

Abstract

The invention discloses a special planting fertilizer for rubber trees. The planting fertilizer comprises the following elements in percentage by weight: N, P and K, wherein the content of total nutrients of N, P and K in effective nutrients is more than or equal to 7.5 percent, the content of organic matters is more than or equal to 45 percent, the moisture content is less than or equal to 30 percent, and a weight ratio of N to P to K is 2 to (4-5) to (0.8-1.2). When a certain amount of the special planting fertilizer for rubber tree disclosed by the invention is applied at a time, the requirement on nutrients of the planted nursery stock in a quite long time can be met, the survival rate and forest form uniformity of the planted nursery stock can be improved, and the application and fertilization frequency of chemical fertilizers is reduced.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a formula and a preparation method of a special planting fertilizer for rubber trees. Background technique [0002] Hevea brasiliensis ( Hevea brasiliensis ) As the main source of natural rubber, it has always occupied an important position in the development of the world economy. It is a very important tropical economic and energy crop. Because its origin is located in the Amazon River Basin near the equator, the litter in the tropical rainforest Accumulated and decomposed, the soil appears loose, breathable, fertile, and moist. Generally, it can be put into production about 6 years after planting. However, in my country's Hainan, Yunnan, and Guangdong rubber planting areas, acidity, stickiness, board, and thinness are the main characteristics of the soil in this area. In addition, the rubber planting unit or the grower prefers to use chemical fertilizers or some ...

[0002] Hevea brasiliensis ( Hevea brasiliensis ) As the main source of natural rubber, it has always occupied an important position in the development of the world economy. It is a very important tropical economic and energy crop. Because its origin is located in the Amazon River Basin near the equator, the litter in the tropical rainforest Accumulated and decomposed, the soil appears loose, breathable, fertile, and moist. Generally, it can be put into production about 6 years after planting. However, in my country's Hainan, Yunnan, and Guangdong rubber planting areas, acidity, stickiness, board, and thinness are the main characteristics of the soil in this area. In addition, the rubber planting unit or the grower prefers to use chemical fertilizers or some organic matter that is not fully fermented and decomposed when planting, or even does not apply the base fertilizer for planting, resulting in problems such as uneven forest appearance, serious lack of plants, more grandson seedlings, and slow growth of seedlings. , resulting in failure to put into normal production 7-8 years or even 10 years after planting
