为了解中槐生长规律和不同条件下的生长情况 ,我们对中槐片林和散生木采用了标准地和优势木调查。其生长规律是前 5年高生长快 ,但径生长慢 ,5年后高生长减缓 ,而径生长较快 ,材积1 5年后生长加快 ;中槐生长一般随海拔增高而减缓 ;不同地形部位生长以原面和川道为好 ,其次为沟底 ,沟坡中部生长最差 ;不同土壤生长以 土和黄土善 土为最好 ,其次为黄绵土 ,绵沙土最差。
In order to understand the law of growth of Chinese white locust and the growth under different conditions, we used standard and dominant wood survey of Chinese scholartree forest and Chinese pine wood. Its growth pattern is fast growth in the first 5 years, but slow growth in diameter, high growth slowed down in 5 years, and growth of diameter was faster and growth accelerated 15 years later. Growth of medium locust generally slowed down with altitude increasing. Growth in the original surface and Sichuan Road as well, followed by the ditch, the worst growth in the middle of the ditch; different soil growth with loess and soil is the best, followed by loessial soil, cotton sand soil worst.
