| 摘 要： | 对针叶豌豆新品种MZ-1和对照品种多纳夫的抗旱性进行对比研究,结果表明：针叶豌豆MZ-1的产量和地上生物量均高于对照多纳夫,与多纳夫相比,增产454.15～843.80 kg/hm^2,干物质生产效能和水分利用效率分别增加3.13～7.73 kg/（hm^2.mm）和2.37～3.85 kg/（hm^2.mm）,开花期植株成活数量及存活率明显提高,相对于对照品种多纳夫的抗旱指数为6.28,抗旱性较强。

| Abstract: | The field experiment conducted to compare the drought-resistance between MZ-1（the new pea cultivar with needle leaves） and Duolafu（the control pea cultivar with needle leaves）.The results shows that compared to the control cultivar,the grain yield and biomass of MZ-1,the new needle pea cultivar,were higher,the grain yield was increases of 454.15～843.80 kg/hm^2,and the dry matter production efficiency and water use efficiency were increased of 3.13～7.73 kg/（hm^2· mm） and 2. 37 ～ 3.85 kg/（hm^2· mm）, respectively, the quantity and rate of survival were increased in flowering stage. The drought resistant index of the control cuhivar Duolafu, was 6.28, the new pea cultivar with needle leaves MZ-1, shown more higher drought resistant ability. |
