Problems solved by technology

Tropical Agricultural Sciences, 2003, 23 (1): 61~66), has caused serious pollution to the natural environment, and the widely distributed brick red soil has high iron and aluminum content, which seriously fixes phosphate fertilizers. Therefore, it is urgent to develop a suitable for tropical plants. Fertilization method

Abstract

The invention discloses a slow-release fertilizer pot and a preparation and fertilizing method thereof. The method comprises that fertilizers, trace elements and the like which are required by plants are placed in the fertilizer pot, the fertilizer pot is buried at roots of the plants, and the fertilizers or trace elements penetrate out of the fertilizer pot or are attached to the fertilizer pot and are supplied for the roots of the plants. The problems that in tropical zones, leaching of nitrogen and potassium is rapid and immobilization of a phosphatic fertilizer is severe are solved, the method which uses the fertilizer pot formed by pressing of plant fibers for containing fertilizers is used for providing fertilizers for the roots of the plants stably in a long time, the utilization ratio of the fertilizers is above 40%, the fertilizer pot can be used for directive root cultivation of the plants and improvement of the soil environment, application effects of long-term plants and cash crops such as rubber trees and mangos are remarkable, and the fertilizing method is high-efficiency and environment-friendly.

Description

technical field [0001] The invention relates to a slow-release fertilizer pot and its preparation and fertilization methods. Background technique [0002] my country has a large population and limited land resources. To increase crop yield per unit area on limited land resources, increasing fertilizer input is one of the effective methods. For long-term economic crops such as mango and rubber in the tropics, the current method of fertilization is mainly hole application and the amount of fertilizer is huge, while in the tropics, the rainfall is heavy and concentrated, and too much fertilizer is applied at one time, and the plant roots cannot absorb it all at once. Water leached out of the root or was fixed by the soil, and more than 70% of the fertilizer was wasted and lost (Lin Qinghuo, Luo Wei, Lin Zhaomu, Cha Zhengzao. Research progress on nutrient leaching of dryland soil fertilizer in brick red soil area. Tropical Agricultural Science, 2003 , 23(1):61~66), causing seri...
