Abstract:
The plant-type of maize shows direct relation with the early growth of soybean under wheat/maize/soybean relay-cropping pattern.The effects of seedling shading (0,35%,45%,55% shading)on morphogenesis and substance accumulation of soybean，s stem were studied by the outdoor simulation pot experiment.The results showed that 35% shading maybe the critical light intensity to maintain the growth of stem for Gongxuan 1.The larger the shading intensity，the more greatly the dry matter partitioned to stem，but the weight per unit length of basal internodes (cytoledon node，first internode and second internode) increased slowly.When transferred to natural light after V9 stage，the effects of seedling shading became insignificant.The accumulation rate and distributive rate of dry matter in stem and the increase of the weight per unit length of basal internodes returned to the level of check.And the weight per unit length of cytoledon node and the first internode increased rapidly during the period of R4～R6 stage，resulting in compensation effect.After seedling shading，stem diameter，stem dry weight，stem (main stem and basal internodes ) weight per unit length and the content of cellulose in main stem showed significant negative correlation with lodging rate at 5% level，and the content of lignin in main stem at 1% level.In conclusion，lower seedling shading intensity is benefit for the growth and lodging resistance of soybean，s stem.Hence，the upright-leaf maize should be chosen to reduce the shading stress on soybean in production
