摘要
试验选择了具有代表性的来源于黄河流域三类熟性类型的8个棉花品种,在江西九江以春季营养钵育苗移栽的方式进行种植,比较其生长发育表现。结果表明:一是各个品种的生育期有以130 d为中心的"趋中"趋势;二是在营养生长速度方面,三类熟性品种表现为早熟品种<中早熟品种<中熟品种,在生殖生长速度方面,前中期表现为早熟品种>中熟品种>中早熟品种,但在中后期中早熟品种的生长发育速度明显加快,最终超过其他两类型熟性品种;三是中早熟品种产量最高,早熟品种和中熟品种产量相当;四是在目前的春季营养钵育苗移栽种植方式下,中早熟品种更适合赣北棉区种植。
This testselected8 cottonvarieties fromtheYellowRivercottonareawhichwere3 kindsof representativema turity types and planted in Jiujiang of Jiangxi province by the form of block seedling transplanting in spring to compare their re spective growth and development. The results showed：First,the growth period of each varieties taked the130 d as the center of the＂middle＂trend;Second,In the aspect of vegetative growth rate show that early-maturing varieties 〈 medium-early maturing varieties 〈 medium maturing varieties,Intheformermidium-term of the reproductive growth rate show that early-maturing varieties 〉medium maturing varieties〉 medium- early maturing varieties,but the medium-early maturing varietiesgrowth rate accelerated obviously in the middle and later periods and finally exceeded the other two types;Third,the yield of medium- early maturing varieties was the highest,the other two types was equal;Forth,in the present planting mode of block seedling transplanting in spring,themedium-earlymaturingvarietiesweremoresuitableforJiangxicottonregionplant ing.
