Effects of Green Plant Growth Regulators on Seed Germination and Seedling Growth of Maize in Soil with Different Salt Concentrations
In order to verify whether green plant growth regulator GGR(deep planting fertile soil)and GGR(special fertilizer mix)can promote maize germination and seedling growth in moderate and severe salinized soil,the salt-tolerant maize variety Woyu 3 and salt-sensitive maize Jiyuan 878 were selected as experimental materials in this experiment,and seed mixing treatments were carried out before planting.The effects of GGR(deep planting fertile soil)and GGR(special fertilizer mix)on seedling emergence,seedling growth characteristics and physiology of maize were studied.The results showed that compared with CK,GGR could improve the seed emergence rate,and promote the agronomic and physiological indexes of maize seedlings to different degrees.According to the membership function analysis,in the three salt concentration soils,in light soil and 0.5％saline soil,the promotion effect of GGR(special fertilizer mix)on seed germination and growth of salt-tolerant maize Woyu 3 was better than that of GGR(deep planting fertile soil).In 0.3％saline soil,the promotion effect of GGR(deep planting fertile soil)on seed germination and growth was better than that of GGR(special fertilizer mix).In light soil,the promotion effect of GGR(deep planting fertile soil)on seed germination and growth of salt-sensitive maize Jiyuan 878 was better than that of GGR(special fertilizer mix),in 0.3％saline and 0.5％saline soil,the promotion effect of GGR(deep planting fertile soil)on seed germination and growth was better than that of GGR(special fertilizer mix).
