Abstract
In order to provide the basis for the application of soybean seed grading sowing technology,soybean seeds of Suinong 14 were classified into four grades by mechanical selection and the indexes of indoor germination rate,seedling loss rate,agronomic traits including plant height,stem diameter,height of lowest pod,nodes number,branch number as well as yield were tested.Germination rate and field seedling loss rate of P1(big seed) was lower than other treatments,while P4(small seed) showed contrary trend compared with P1.The field survival seedling rate varied with seed size,there were very significant difference between P2(bigger seed) and P4,P6(bigger seed mixed with middle seed)and P4;the difference between P1 and P4,P3(middle seed)and P4 reached significant level,with P2 the highest.Significant or very significant difference for agronomic traits including height of lowest pod,node number,reproductive node number and branch number except plant height and stem diameter were observed among different treatments.Yield of the single sowing of P2、P3 and mixed sowing(P6)were increased than ungraded seed(P5),yield of P6 increased by 14.21% compared with P5.Compared with P5,the weighted yield of four graded soybean seeds increased by 27.80%.The weighted yield of P2 and P3 respectively sowing increased by 19.44% and 34.41% compared with P6 and P5,respectively.Results suggestted that soybean seed grading sowing is a simple,economic and applicable technology.
