Breeding and High-Yield Cultivation Techniques of Bancao No. 2

摘要: 板草2号是2009年从地方品种板桥本草(宁波中种)中发现的变异株，经株行株系和品系比较试验育成的板草2号新品系。经3年品系比较试验，板草2号平均理论产量每亩1323.5公斤，比对照宁波中种增产6.67%。实收产量每亩1158.2公斤，比对照宁波中种增产9.43%。2017年8月8号通过安徽省非主要农作物品种鉴定登记委员会鉴定登记。板草2号特征特性，属多年生宿根性草本植物，地上茎直立，圆柱形，翠绿色、基部偏淡；茎粗均匀，整齐度好，韧性较好；髓心连续，呈白色，茎梢针状，有3~4枚褐色叶状鞘；地下茎匍匐，有粗短节，每节长度平均1.3 mm左右，外被褐色鳞片；分蘖力强，着花少，花朵呈簇生状或聚伞状，雌雄同花。

Abstract: Bancao No. 2 is a variant strain found in 2009 from the local variety Banqiao Bencao (Ningbo Zhong variety), a new strain of Bancao No. 2 bred through a comparison test of plant lines and strains. After 3 years of comparison test of strains, the average theoretical yield of No. 2 is 1323.5 kg per mu, which is 6.67% higher than the control Ningbo Zhong variety, and the actual yield is 1158.2 kg/mu, which is 9.43% higher than the control Ningbo Zhong variety. It passed the appraisal and registration of the Anhui Province Non-major Crop Variety Appraisal and Registration Committee on August 8, 2017. The characteristics of Bancao No. 2 is perennial herbaceous plants.
