苏长茄(早熟品种)在大棚冷床内播种,分别于破心期和1,2,3,4,5片真叶期分苗。试验结果表明:1叶期分苗叶片数、开展度、茎粗、最大叶片面积、单株叶面积、地上部干重、根干重、壮苗指数、花芽分化指数最高,且成苗高度、节间长适中,根系发达。5叶期分苗秧苗质量显著降低。
Su longzhu (precocious varieties) in the greenhouse cold bed sowing, respectively, in the broken heart and 1,2,3,4,5 true leaf period seedlings. The results showed that the leaf number, the degree of development, the stem diameter, the maximum leaf area, the leaf area per plant, the aboveground dry weight, the root dry weight, the strong seedling index and the flower bud differentiation index in one leaf stage seedling were the highest, Internode length, root system developed. 5 leaf stage seedling seedlings quality significantly reduced.
