一、培育壮苗壮苗是提高茄子杂交制种产量的重要环节,因此,培育壮苗是杂交制种的关键措施。壮苗的标准是:根系发育好,茎秆粗壮,节间短,叶色深绿有光泽,无徒长苗、病虫危害苗、瘦弱苗,并有部分出现花蕾。 1.育苗前的准备:温室的修建一般以座北向南单斜面,以塑料棚膜代替玻璃的简易温室较为经济实用,要求东、西、南三面无遮挡物,以利室内采光。室内要求地面平整无杂物、无土块。用营养土装袋,比例为3:1,即用未种过茄科作物的田土三份,腐熟的优质农家肥一份,加千分之五的复合肥掺匀,营养袋以口径5～7厘米,高9厘米左
First, cultivating strong seedlings is to enhance eggplant hybrid seed production an important part of the yield, therefore, nurturing strong seedling is the key measure of hybrid seed production. Strong seedling standards are: good root system development, stalks thick, internodes short, dark green leaf color, without premature seedlings, pests and diseases endangered seedlings, thin seedlings, and some flower buds. 1. Pre-nursery preparation: Greenhouse construction generally north-south seat single bevel, plastic greenhouse film instead of glass simple greenhouse more economical and practical, requiring east, west and south no shelter on three sides, to facilitate indoor lighting. Indoor requirements of the ground level without debris, no soil. With nutrition soil bagging, the ratio of 3: 1, that is, not soaked with solanaceous crops in three copies of the field, a high-quality decomposed manure, plus five thousandths of compound fertilizer, nutrition bags to caliber 5 ~ 7 cm, 9 cm high left
