不同栽培模式对黔引普那菊苣农艺性状及产量的影响

采取撒播、条播、穴播和育苗移栽4种栽培模式种植黔引普那菊苣，观测其生育期、再生速度、产苹量。结果表明：黔引普那菊苣在黔南温热地区4种栽培模式上均能很好地完成生育期，不同栽培模式之间生育天数、生长天数以及再生速度差异不显著（P〉0．05）。4种栽培模式以穴播产量最高，撒播次之，育苗移栽最低，条播、撒播、穴播分别比育苗移栽提高8194、9134和10146kg／hm2,差异显著（P〈O．05）。建议田间规模种植时采取穴播。

Impact of Cultivation Modes of Puna Chicory on its Agronomic Traits and Yield

The agronomic traits and yields of puna chicory under four cultivation modes(taking sowing,drilling,dibbling and transplanting seedling)were compared by observing their growth period,regeneration rate and grass yield in warm area of Qiannan Prefecture.The results showed that the puna chicory completed the reproductive phase of growth well under four cultivation modes,there were no significant differences(P>0.05)in the fertility day,growth day and regeneration speed of puna chicory under the cultivation modes.In the four cultivation modes,the yield in dibble mode was the highest,and the yield in the transplanting seedling was the lowest.Compared with the transplanting seedling,the yields in drilling mode,sowing mode and dibbling mode were higher by 8 194 kg/hm2,9 134 kg/hm2and 10 146 kg/hm2respectively.So the dibbling mode was the best for puna chicory plant.
