芝麻与大豆间作套种增效技术研究

Research on Technology of Improving Efficiency when Intercropping Sesame with Soybean

目的:建立较优的芝麻与大豆间作套种的配比模式。方法:试验采用随机区组设计,6个处理,3次重复,共计18个小区,小区畦宽1.8m、沟宽0.5m,面积为18m2。6种处理(芝麻∶大豆)分别为T1(3行芝麻、3行大豆)、T2(2行芝麻、4行大豆)、T3(2行芝麻、6行大豆)、T4(4行芝麻、2行大豆、T5(CK,16行大豆)、T6(CK2、6行芝麻)。结果:初步得出了最优配比即3行大豆//3行芝麻处理,产值和土地当量比(LER)最高,分别为13117.2元/hm2和1.06;大豆产量1377 kg/hm2,芝麻产量591.6 kg/hm2;较单作大豆、芝麻收益增加6.92%、4.77%。结论:该研究为芝麻与大豆间作的最佳种植配比提供理论依据。

The research aimed to establish an optimized combination of intercropping technology of intercropping sesame with soybean. Method ： The complete randomized block design , with six treatments and three repeats. There were eighteen experimental plots and each plot was 18 m^2 with community qikuan 1.8m and wide ditch 0.5m. The Six kinds of treatment were 3 line sesame and 3 line soybean （T1）, 2 line sesame and 4 line soybean （T2） ,2 line sesame and 6 line soybean （T3） ,4 line sesame and 2 line soybean（ T4）, only 6 line soybean（ TS/CK1 ） and only 6 line sesame（T6/CK2） respectively. Result：Output value and land equivalent ratio （LER） of T1 treatment were the highest with 13117.2 yuan/hm^2 and 1.06 respectively;Soybean yield was 1377kg/hm^2, Sesame yield was 591.6kg/hm^2 ;The income was increased 6. 92% and 4. 77% compared with only planning soybean and sesame treaments. Conclusion： The study provides a theoretical basis for finding the best intercropping combinations of sesame and soybean.
