One-year-or two-year-old trees of the nectarine varieties Zaohongbaoshi,Huyou 004,and Huyou 018 were used to study the effects of root restriction adopted in protected fruit-tree farming on the light-intercepting capability in the canopy,the soluble protein content in the leaves and the leaf weights of young nectarine trees.

<Abstrcat> This study was performed during a continuous period of two years on young nectarine trees in greenhouse.

Effect of meteorological factors on sprout of young walnut trees and their control measures;

With pot experiment,the influence of soil water content on the biomass and water content of aboveground parts and roots,water-holding capacity,relative conductivity and activities of cell defense enzymes in the leaves of Elaeagnus mollis Diels seedlings was studied.

Effects of root-divided alternative irrigation on soil moisture distribution and root-trunk sap flow dynamics of peach trees;

Effects of alternative partial rootzone irrigation on peach growth,productivity,and water use efficiency;

Effect of CO2 Enrichment on Some Characteristics of Fruit of Peach Tree in Greenhouse;

Study on water use of drip irrigated peach tree under the conditions of fully irrigated and regulated deficit irrigation;

Research on the impacts of soil water potential on a few physiological indicators of peach tree

The paper has a aim at the current problem that the chemical agrochemicals are mainly ap-plied to prevent and cure the diseases and insect pests in peach tree production and make the e-cosystem environment polluted.
