Abstract:
In order to investigate the response of less branched soybean varieties to increased density in the context of improved agricultural machinery and precision sowing technology，to explore their optimum sowing density and to optimize soybean cultivation patterns，this study used two varieties with different branching types (less branched variety Zhongzuo XA12938 and more branched variety Zhonghuang 13)as test materials and planted at six densities(1.35×105，1.80×105，2.25×105，2.70×105，3.15×105 and 3.60×105 plants?ha-1) from 2018 to 2019.The planting densities(1.80×105，2.25×105，2.70×105，3.15×105 and 3.60×105 plants?ha-1) were used to study the photosynthetic characteristics and yield differences between varieties with different branching types under close planting conditions.(1) Canopy light interception rate increased with increasing planting density and stabilized at 2.70×105 plants?ha-1，with 4.90% higher light interception in the canopy during the critical period in Zhongzuo XA12938 compared to Zhonghuang 13.(2) The SPAD increased with increasing density and the highest SPAD values could occur earlier up to the R3 stage at high density treatments (3.15×105 〖JP3〗and 3.60×105 plants?ha-1).In addition，the high SPAD values lasted longer in Zhongzuo XA12938 compared to Zhonghuang 13.(3) Fv/Fm decreased with increasing planting density，and the decrease was greater for Zhonghuang 13 (5.10%) high density treatments than for Zhongzuo XA12938 (3.51%).The photodamage percentage Y(NO) of Zhongzuo XA12938 increases less with increasing density between treatments and the maximum value occured later compared to the photodamage percentage Y(NO) of Zhonghuang 13.(4) The maximum net photosynthetic rates of Zhongzuo XA12938 and Zhonghuang 13 were 30.46 and 24.34 μmol?m-2?s-1，respectively，and the decrease in net photosynthetic rate with increasing planting density was smaller in Zhongzuo XA12938 (17.73%) than in Zhonghuang 13 (22.51%)，with Zhongzuo XA12938 showing an advantage in net photosynthetic rate at all densities.(5) With increasing planting density，soybean yield generally tends to increase before leveling off.Yield increases were achieved when planting density was greater than 1.80×105 plants?ha-1.In addition，comparing the two varieties，we found that Zhongzuo XA12938 had a higher yield potential and was more tolerant to dense planting.It was found that increasing planting density was beneficial to the improvement of soybean light energy use efficiency，and although the photosynthetic capacity of soybean individual plants decreased，the net photosynthetic rate and Fv/Fm increased density of less branched varieties decreased in a smaller and more stable way.In summary，the less branched variety Zhongzuo XA12938 has a high yield potential，and under dense planting conditions the leaves have a strong green holding capacity，the canopy light energy interception rate and the net photosynthetic capacity of the leaves are strong，smaller increase in percentage of light damage，which is conducive to the use of light energy resources and can increase yields steadily under high density planting conditions.Therefore，in production，we can use less branched and dense planting varieties with more stable photosynthetic characteristics，and increase the planting density appropriately，so as to improve the yield and benefit.Keywords:
