特早熟豇豆新品种夏栽品比试验初报

目的]探讨特早熟豇豆新品种99-1夏栽的生物学特性及可能性。方法]对豇豆新品种99-1和当地主栽品种长豆角(CK)两个豇豆品种进行夏栽品比试验。结果]据两个豇豆品种的植物学特征、生物学特性及农艺性状的品比试验发现,CK营养生长较为旺盛,株高比99-1高约28 cm,叶片数比99-1多。但在荚长、单荚鲜重、每花序结荚数等方面99-1均占优势。前期产量99-1比CK增产62.4%,全期产量99-1比CK增产41.4%。99-1的抗逆性较强,没有发现植株倒伏,早衰现象。结论]特早熟豇豆99-1比对照品种具有结荚多、产量高、荚形美观、耐热、抗旱、植株不易衰老等优点,适宜夏播,伏缺季节上市,可大面积推广。

Preliminary Report on the Compared Experiment in the Early maturity New Cowpea Variety Grown in Summer

Objective] The biological characteristics and possibility of early-maturity cowpea variety——99-1 grown in summer were studied.Method] The comparison experiment in new cowpea variety——99-1 and local variety with long bean(CK) was conducted.Results] The experimental result indicated that in the characteristics of botany,biology and agronomic characteristics of two cowpea varieties,CK variety had more vigorous vegetative growth,which plant height was about 28cm higher than that of 99-1 and the number of leaf was more than that of 99-1.However,there were the advantages in the length of pod,fresh weight per singlepod,inflorescence and others in the variety——99-1.The 99-1 yield in the beginning stage was 62.4% higher than that of CK and the final yield of 99-1 was 41.4% higher than that of CK.The variety showed strong resistance,without lodging and early senescence.Conclusion] The early maturity cowpea variety——99-1 had many advantages such as more pod,high yield,good pod-shaped appearance,the tolerance to heat,drought and senescence etc,which was suitable for sowing in Summer for market supply and was extended on a large area.
