Different structures of bamboo clumps are studied by comparing their relative growing rates, the amounts of shooting and quitted shooting as well as the relation between the relative growing rates and the weight of shoots. The results indicate that Clump A, which is made up of five mother bamboos, one two-year-old bamboo and four one-year-old bamboos, is the best.Three soil cultivation treatments of fertilization are adopted, that is, strip plough, overall plough and control plough, comparing their shoots yields and the economic benefits, strip plough is the best, which can bring the biggest profits, up to 17,778yuan/h m2, overall plough follows .Plough is the major preventive treatments of Bambooxiangjia pests, assisted by chemical treatments. Biological and physical treatments. summer and Winter plough are good for the protection of bamboos, better to do that in the early June while the larva Bambooxiangjia pests are getting down into the soil. By doing so, bamboo's injuring rate declines by 60% and the control effect can reach 87.84%. Using20% of the emulsifiable, the controll effect reaches 97.20%. Using different strains of nematodes in the dosage of 2 × 105 · m-2 can also get good results, of which S.carpocapsae Beijing is the best, the connected mortality was 51.35% in ten days after it is treated, The control effect reaches 66.08%. B.bassiana had a poor infected effect on the larva, which is only 32.43% of the corrected mortality after 15days. Spraying the powder of B.bassiana on the ground before the larva going down can reduce the new bamboo's injured rate by 12.52% and thus reaches29.21% of the control effect. Shaking the tips before the peak of the larva going down can reduce the hibernating pests population, the control effect reaches 89.44%. Comparatively speaking, catching the adult pests by hand can also reduce the one-year-old bamboo's victim rate by 43.74%, the control effect reaches 64.50%.
