土壤类型对雷竹出笋数量和鲜笋产量的影响

采用随机区组设计方法,在寿宁县中海拔地区研究不同土壤类型雷竹林的出笋数量和鲜笋产量。结果表明:各种土壤类型的雷竹林出笋数为18 006~23 813个/hm2、鲜笋产量达3.86~6.79 t/hm2。土壤类型对雷竹的出笋数和鲜笋产量均有极显著影响。耕作土壤,尤其以红土和黄泥土出笋数量最多,鲜笋产量最高,其鲜笋产量分别为6.79和6.42 t/hm2、分别比平均值(5.19 t/hm2)大30.8%和23.7%。

Effect of soil type on the quantity and yield of Phyllostachys praecox cv.Prevernalis bamboo shoots

By random experiment design method,the quantity and yield of Phyllostachys praecox cv. Prevernalis bamboo shoot with different soil types were studied in middle elevation area of Shouning County. The results showed that the bamboo shoot number was 18 006 ～ 23 813 individuals per hectare,and the fresh bamboo shoot yield was 3. 86 ～ 6. 79 t / hm^2. The bamboo shoot number and yield were significantly affected by soil type. With the red clay and yellow soil,the bamboo shoot quantity and yield were the highest,of which the yield reached 6. 79 t / hm^2 and 6. 42 t / hm^2 that were30. 8% and 23. 7% larger than the average（5. 19 t / hm^2） respectively.
