茶林间作,搞立体开发,既能增强控制水土流失的效果,又能提高经济效益。茶园间种的树种最好是杉树。其优点有七:(1)杉树与茶树没有共同的病虫害,并对病虫害能起到互相抑制的作用;(2)经济效益相对间种其他树种高;(3)从生物学特性讲,茶树喜散射光,茶杉间作空间层次不同,正好满足茶树这一特性;(4)茶杉根系分布层次不同,可从不同土层固结土壤及水体,更有效地控制水土流失;(5)干旱季节可相互调节土壤温度和湿度;(6)茶园经常松土施
Intercropping tea, engage in three-dimensional development, both to enhance the effectiveness of soil erosion control, but also improve economic efficiency. The best kind of tree species in tea plantations is cedar tree. Its advantages are seven: (1) cedar and tea trees do not have common pests and diseases, and pests and diseases can play a mutually inhibit role; (2) the economic benefits of inter-species other species; (3) speaking from the biological characteristics of tea Scattered light, fir spruce intercrop space for different levels, just to meet the characteristics of tea tree; (4) cinnabar root distribution of different levels, from different soil consolidation of soil and water, more effective control of soil erosion; (5) drought Season can mutually adjust the soil temperature and humidity; (6) Tea plantations often loosen
