不同生育期施用"奥普尔"对夏大豆生长发育的影响
EFFECT OF OPAL APPLICATION IN DIFFERENT GROWTH STAGES ON GROWTH AND DEVELOPMENT OF SUMMER SOYBEAN
摘要
Abstract
Soybean germination rate may be increased to 9. 1% through soil treated withOpal liquid fertilizer. The plant height and 100 seed-weight reduced and the number ofbranches and pods were increased by applying Opal liquid fertilizer during the growing periodexcept for pod filling stage. There was no change of plant height and number of branchesand but number of pods was reduced and the number of seeds per pod and 100 seed-weightwere raised by applying the fertilizer in the stage of pod filling. The result indicated that thenumber of seed per plant, yield and economic benefit may be enhanced by using of the fertil-izer. The yield increased 11.8 % and 9. 6 % respectively when the fertilizer was applied insoil before seeding and sprayed in the flowering stage, and the yield increased 13.6％ whenthose two fertilizer treatments were applied in soybean growth period.关键词
