Discussion on cellar disposition model of cellar irrigated agriculture and it s high efficient utilization;

In order to confirm the effect that reasonable disposition of multi-tree species has the potential to increase resistance of trees to Anoplophora glabripennis,three different disposition model forests were sampled in experimental forest belonging to Xinhuaqiao Farm of Tree Seed and Seeding in Ningxia.

This paper presents the optimal disposition model of grass and forest in slope and relational floristics.

The paper describes the current situation of international cooperation human resources in Datang and discusses how to elaborate the maximum potentiality of existing human resources and human resources configuration modes in international investment projects.

The paper compares and analyzes the planting methods,the configuration mode and the varieties of trees and grasses on ridges based on the practice of integrated management of small watersheds.
