【摘要】 对米邦塔食用仙人掌不同规格种片进行标记 ,定植到田间后 ,定期进行生长动态观测。结果表明 ,菜片产量与种片纵横径、厚度呈极显著正相关 (相关系数分别为 0 .6 70 2、0 .6 5 1、0 .6 2 81 ) ,菜片产量变化幅度较大。根据贵州食用仙人掌生产实际 ,初步提出贵州省米邦塔食用仙人掌种苗 (种片 )质量标准为 :种片纵径≥ 2 4cm ,横径≥ 1 5cm ,厚度≥ 1 .5cm。该项指标可作为贵州食用仙人掌种片质量参考标准更多还原

【Abstract】 Different size of the cactus Opuntia milpa alta Haw(Cactaceae) were marked, and transplanted in the field, and the growth dynamics was regularly observed. The results show that the productivity has positive relation with the vertical diameter, horizontal diameter, and the thickness of the plantlet, the correlation coefficient are 0.6702, 0.651 and 0.6281, and its yields reveal very sighificant variance. According to the production reality of Guizhou, it is suggested that the requirement of plantlet specification for the edible cactus as follow: the vertical diameter should be longer than 24 cm, the horizontal diameter should be longer than 15 cm, and the thickness should be above 1.5 cm. This index can be used as the reference of the plantlet standard for the of the (cultivation) edible (cactus) in Guizhou.更多还原
