冷凉区旱地不同成苗方式对菜豆产量及经济效益的影响

Effect of Different Seedling Methods on Yield and Economic Benefits of Kidney Bean in Dryland of Cold Area

在旱地栽培条件下,研究比较了菜豆原地苗(直播后出苗)、移栽苗、补种苗3种不同成苗方式对菜豆产量及经济效益的影响,以期解决北方冷凉区菜豆春播生产中存在的出苗难、保苗难等问题。结果表明:移栽苗菜豆平均667m2产量比补种苗高137kg,而与原地苗较为接近;采收期内,移栽苗菜豆产量变化趋势始终高于补种苗;且移栽苗经济效益可比补种苗提高9.1%。试验表明,旱地菜豆育苗移栽技术可取代传统多次补种成苗保苗的方法,进而提高菜豆产量和生产效率。

In order to solve the problems of seedling emergence and protection hardly of kidney bean in the production of spring sowing in cold area of north in China, under the conditions of dryland cultivation, the effect of three different seedlings of kidney bean which were the emergency seedlings and transplantation seedlings and replant seedlings on yield and economic benefits were studied. The results showed that the yield of transplantation seedlings was 137 kg per 667 mz higher than replant seedlings,and closer to the emergency seedlings;in the harvest period,the variation trend of yield of transplantation seedlings was higher than replant seedlings all the time, and the economic benefits of transplantation seedlings could be increased by 9.1 ~ than replant seedlings. So, the way of traditional replant seedlings several times could be substituted by the technology of kidney bean seedling transplantation, and it would be beneficial to improve the yield and production efficient.
