Research and Demonstration of Planting Grain Crops under Forest

In order to carry out research and demonstration of planting grain and oil crops under forest（young forest），different modes of planting sweet potato and mung bean under forest were contrastively tested，and experimental results were analyzed and optimal schemes were given.Experiment results and study could provide reference for determination of high-efficiency forest-grain production model，so as to achieve purpose of promoting growth of trees and increasing grain yield and efficiency.
