“Seedling good frame seedlings, seedlings and good harvest half.” Seedling quality for the greening after rice seedling growth, rice growth and yield formation has an important role. Different varieties or the same variety under different cultivation conditions, the quality of the seedlings are different. Excellent rice varieties or seedlings under good cultivation conditions should be robust, tidy and vigorous in seedling stage, vigorous growth, and have excellent morphological and physiological characteristics, such as broad leaves and green leaves , Roots developed, strong photosynthesis and so on.
