Problems solved by technology

Especially since the large-scale promotion of Ethephon to stimulate rubber tapping in the rubber planting area of ​​Yunnan, as the output of dry rubber per unit area has increased significantly, the loss of nutrients in rubber trees has been accelerated. The fertilizer management technology under the traditional rubber tapping system is no longer compatible with the new rubber tapping system.
The fertilization formula for rubber trees has obvious timeliness, and the fertilization formula proposed by the census results many years ago can no longer be used for symptomatic fertilization; moreover, the current fertilizer formula is too complicated

Abstract

The invention discloses a special rubber tree fertilizer for promoting high and stable yields, and a fertilization method of the fertilizer. The special rubber tree fertilizer comprises the following active ingredients in parts by mass: 11-15 parts of nitrogen, 7-12 parts of phosphorus pentoxide, 8-18 parts of potassium oxide, 2-4 parts of magnesium oxide, 0.2-0.4 parts of N-(n-butyl)thiophosphoric triamide, 0.1-0.2 parts of 3,4-dimethylpyrazole phosphate and 3.6-4.8 parts of organic matter; and the total nutrient content is 41.6-43%. The fertilization method comprises the steps that a fertilizer trench is dug; a conventional commercial organic fertilizer or farmyard manure is applied; the special rubber tree fertilizer is applied after several months; earthing is performed; and green manuring fertility is performed matched with crabrooting hilling and forest vegetation management. The fertilizer creates a loose, fertile, wet and ventilated soil environment for a rubber tree, and continuously and stably provides nutrients. After the special rubber tree fertilizer is applied, a nutrient deficiency symptom of the rubber tree is alleviated; the nutrients overall trend to balance; and the rubber yield is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural and forestry fertilizers, and in particular relates to a rubber tree special fertilizer for promoting high and stable yields and a fertilization method thereof. Background technique [0002] Natural rubber is an important strategically binding resource. Yunnan is the largest natural rubber production base in my country. At the end of 2013, the rubber planting area reached 8.3145 million mu, of which 3.9393 million mu was opened and tapped. Reasonable fertilization is one of the important technical measures for fast growth, high yield and stable yield of rubber trees. The nutrient distribution ratio of rubber tree special fertilizer is determined according to the soil nutrient status of rubber gardens in various places, the characteristics of rubber tree growth and rubber production. It contains nitrogen, phosphorus, potassium and trace elements. The fertilizer is compounded and has a long fe...
