Abstract:

To study the effects of different planting parameters on yield and photosynthetic characteristics of summer soybean, taking ‘Baodou 6’ and ‘Qindou 10’ as experimental materials, we set the orthogonal design (L934) with 4 factors and 3 levels. The results showed that: different treatments had different effects on yield and photosynthetic characteristics (P<0.05), the yield of treatment 3 was the highest which increased by 2.24%-24.27% compared with that of others; moreover, Pn, Ci, and Tr of treatment 3 were the highest, and they increased by 17.31%-61.44%, 5.26%-28.62%, 6.8%-9.36% compared with that of others, respectively; leaf WUE of treatment 3 was the highest, the next was treatment 6, and the last was treatment 7; leaf WUE of blooming period was higher than that of seed-filling phase; the planting date (20 June), planting density (150000 plants/hm2), compound fertilizer (225 kg/hm2), and boric fertilizer (3.0 kg/hm2) had the highest leaf WUE in tested phase. The combination of planting parameters has a significant effect on the yield and photosynthesis performance of summer soybean, and treatment 3 is an optimal planting group.
