Abstract:
In order to meet the people’s need for high quality development and high-quality plant produce, most of original vegetation changed into artificial vegetation, such as plantation, grass and crops. As plant grow, there are soil dryness, soil and vegetation degradation and crop failure in water-limited regions, which is not good for vegetation high-quality development in water-limited regions. After a couple of years research, the results showed that plant resources relation has to be regulated. The theory foundations of plant resources relation regulation are natural resources use limit by plants, vegetation carrying capacity and the critical period of plant resources relation regulation. The resources use limit by plants, Vegetation carrying capacity and the critical period of plant resources relation regulation include space resources use limit by plants, space Vegetation carrying capacity and the critical period of plant space in soil water and nutrient rich region, soil water resources use limit by plants in water-limited regions, soil water vegetation carrying capacity and the critical period of plant water relation regulation in water-limited regions, and soil nutrient resources use limit by plants, soil nutrient Vegetation carrying capacity and the critical period of plant soil nutrient relation regulation. The method of vegetation high-quality development is to select excellent plant species or varieties, which is suitable for the growth in the local condition and there produce is meet the need of market, take appropriate initial plant density, which is equal to or more than vegetation carrying capacity in the critical period of plant resources relation regulation and take effective measures to regulate the relationship between plant growth and nature resources to ensure plant grow well and produce high-quality plant product and get the maximum yield and benefit.
