摘要
共设置1个对照和5个处理,分别为露地直播(对照)、大棚直播(处理①)、地膜直播(处理②)、露地移栽(处理③)、大棚移栽(处理④)、地膜移栽(处理⑤),研究不同栽培模式对四棱豆生育期、生物量及主要农艺性状的影响。结果表明,6种栽培方式对四棱豆生育期产生不同程度的影响,且以大棚移栽处理下的四棱豆始花期最早、终花期最晚,即花期最长,达97 d,结荚周期最长,达95 d。育苗移栽处理下四棱豆的生长势、单产、总产均强于或高于直播处理;采用大棚模式种植四棱豆均有利于块根和鲜荚的高产,且以大棚移栽最佳。主成分1、2、3的特征值分别为6.19、3.30和1.11,这前3个主成分的累计贡献率达96.36%,且以主成分1的贡献率最大,达56.28%。四棱豆各农艺性状中,鲜荚总产量(X_(11))、单株鲜豆荚重(X_(9))、主蔓节位数(X_(2))、单株分枝数(X_(3))、单株结荚数(X_(6))、主蔓长(X_(1))6个指标对四棱豆产量影响较大。
A total of 1 control and 5 treatments were set up,including direct seeding in open field(control),direct seeding in greenhouse(treatment①),direct seeding with plastic film(treatment②),open field transplanting(treatment③),greenhouse transplanting(treatment④)and plastic film transplanting(treatment⑤),to study the effects of different cultivation modes on the growth period,biomass and main agronomic characters of winged bean.The results showed that six cultivation methods had different effects on the growth period of winged bean,and first flowering period and the last flowering period of winged bean under the greenhouse transplanting treatment were the earliest,that was,the longest flowering period,up to 97 days,and the longest pod setting cycle,up to 95 days.The growth potential,yield and total yield of winged bean under seedling raising and transplanting treatment were stronger or higher than those under direct seeding treatment;planting winged bean in greenhouse was beneficial to the high yield of root tubers and fresh pods,and transplanting in greenhouse was the best.The ei-genvalues of principal components 1,2 and 3 were 6.19,3.30 and 1.11 respectively.The cumulative contribution rate of the first three princi-pal components was 96.36%,and the contribution rate of principal component 1 was the largest,reaching 56.28%.Among the agronomic traits of winged bean,the total fresh pod yield(X_(11)),the fresh pod weight per plant(X_(9)),the number of main vine nodes(X_(2)),the number of branches per plant(X_(3)),the number of pods per plant(X_(6)),and the length of main vine(X_(1))had a greater impact on the yield of winged bean.
