Abstract

Modern agricultural want land to efficiently produce plant products and benefits to meet people's needs. However, because better plant species and varieties and overuse of fertilizer and pesticide alters the plant resources relationship, easily resulting in soil and vegetation degradation, crop failure or waste of resources, influence quality of fruit and benefit, which are unfavorable for the sustainable utilization of nature resources and food security. After a couple of years study, the results showed that the theory foundation of the sustainable utilization of natural resources and Agriculture high quality production is the resources use limit by plants, vegetation carrying capacity and critical period of plant resources relationship regulation. And the methods of Agriculture high quality development is to select excellent species or varieties based on site condition before planting crop young plant and sowing seed, adopt appropriate initial planting density when planting crop young plant and sowing seed, and regulate the relationship between plant resources in the process of crop production in a timely and appropriate amount, specially the chemical fertilizer to obtain the maximum yield and benefits, realize the sustainable utilization of natural resources and achieve high quality agricultural production.
