In order to reveal effect of the intercropping pattern of chestnut with tea on soil enzyme activities and soil nutrients, analysis on soil enzyme activities and soil nutrients of three different cropping pattern were conduted.

Effects of intercropping pattern of Chinese chestnut with tea on photosynthetic characteristics in tea bushes;

Through investigating and analyzing intercropping pattern of jujube with crop at old Yellow River way area,Yubei,researching techniques shortenized and densely planting jujube,and techniques wheat later sowing and earlier harvesting and cotton cultivating with plastic film mulches,intercropping pattern of jujube with cotton and wheat was expounded.

It is expatiated that the intercropping pattern and the developing course in planting rubberarea of Yunnan.

The results indicate that the output value,the net income per Mu or per labor day,and the output/input radio of the three intercropping models were able to be increased by 3.

The study on the tea-rice intercropping compound system in southern Auhui mountainous regions showed that leaf area index of this system was higher than that of the single culture tea garden, which was beneficial for the system to fully use light,soil and gas resources.
