Abstract: Utilization of Myrica rubra resources was studied from different aspects .Myrica rubra in Zhejiang occupies an area of 38 000 hm2 , with an approximate annual yield of 130 000 .Ningbo , Taizhou andWenzhou are the main producing homes , which account for 74.76 %of the total in area and 78.39 % of the total in yield of the whole province , respectively .In these main producing homes , most of the groves have an average yield of 7.5 ～ 9.75 thm-2 , with some small groves producing 45.00 thm-2 red bayberries .There are big differences in yield between alternate years .The yield reduced by 65.95 % every other year .The canopy of the species is strong in obstructing storms and reducing soil surface erosion and the water-holding capacity .As a result , the surface erosion is less than that on the grassed slope by 11 %;the litter under the canopy has a depth of 5.5 cm on the average ; and each adult tree can hold 0.3 ～ 0.69 m3 of rainfall .Actinomyces were found in the root system, which has markedly increased soil fertility , yield and the economic effect of the non-timeber species that were mixedly planted with Myrica rubra .Myrica cubra has a strong adaptability .Its young trees are tolerant of shade and can be planted on soil with severe water-cum-soil losses , thin stony loam and soil-forming parent rock .If reforestation is conducted in surviving pine groves , a grove of seed trees or miscellaneous shrubs , it wouldnt be necessary to destroy the original vegetation .In addition , superior cultivars with some characteristics , their nutrients , processing and utilization are also introduced here in this paper .
