Abstract:We have made a comparative study on the colony structures of large mulberry fields which var1eties,ecological conditions and the growing density are relatively identical. The chang laws of effective shoots,average single leaf area,leaf weight and leaf area index in the three yields of mulberry fields i. e.the highest output (45000kg/hm2), high output (37500kg/hm2) and average output (30000kg/hm2) have been probed. The auther put forward the main indexes about mulberry colony structures for the highest output in Panxi area.
Keywords:mulberry fields  the highes output  colony structures  leaf area index
