Dynamic management method for soil nutrients in rubber plantation

Abstract

The present invention provides a dynamic management method for soil nutrients in a rubber plantation, comprising the following steps: dynamic managing target for the soil in the rubber plantation is determined according to the soil fertility level; the short-term target yield in the rubber plantation is determined in accordance with the current natural rubber price fluctuation and combined with the soil yield level; soil managing measures of soil in the rubber plantation under the dynamic management target for the soil of the rubber plantation is determined according to the dynamic management target for the soil of the rubber plantation and the short-term target yield in the rubber plantation; the soil management measures comprise: the application amount of organic fertilizers, the application amount of inorganic fertilizers and a dynamic fertilizer application method. Through the dynamic management method for the soil nutrients in the rubber plantation, on the one hand, rubber planters / rubber planting enterprises can use the minimum investment to obtain the maximum economic benefit so as to improve the input-output ratio; on the other hand, through the method, the goal of utilizing and nourishing rubber trees and utilizing and nourishing the land can be achieved; therefore, the stability of china's natural rubber total output and the sustainable development of natural rubber industry can be ensured.

Description

technical field [0001] The invention belongs to the technical field of soil management, and in particular relates to a dynamic management method for soil nutrients in rubber plantations. Background technique [0002] Natural rubber is an important strategic material and industrial raw material. The development of my country's natural rubber industry aims to ensure the security of my country's natural rubber supply, with the core of increasing the income of rubber farmers and enhancing the competitiveness of the natural rubber industry. [0003] Natural rubber is mainly produced in Hevea brasiliensis, which is also known as Hevea brasiliensis. It is native to the western region of Mara Mountain in the Amazon River Basin of Brazil. It has the ecological characteristics of high temperature, rain, calm wind and fertile soil. It is mainly distributed in the north and south latitudes. Within 10°, the rubber tree planting in my country is mainly located at 18-24° north latitude. Due...

Problems solved by technology

[0006] In recent years, with the sharp drop in international natural rubber prices and the increase in labor costs in my country's natural rubber industry, rubber farmers and rubber planting companies are on the verge of losing money. Workers in enterprises adopt methods such as forced mowing to ensure income by increasing production, which leads to prominent contradictions between the short-term production goals of natural rubber and the long-term sustainable development goals of using trees to raise trees, using land to raise land / cultivating soil fertility, and seriously affect The sustainable development of my country's natural rubber industry
