我市茄果类蔬菜温床育苗技术一直停留在老水平上,头年小雪播种,至翌年清明前后定植,占用苗床数月,耗费了大量人力、物力。同时,采取控温控水的办法抑制幼苗生育,苗龄过长,培育出的“老小苗”产量不高。再者由于1月份久雨低温,育苗难度大,历年死苗情况不同程度的存在,轻者一般死苗率20—30％,重者达90％以上。蔬菜工厂化育苗是近年来蓬勃发展的一项新技术,它是按照茄果类生物学特性,在人为控制优越的环境条件下,有效地促进幼苗生长发育,培育出苗齐、苗壮、根系发达、成活率高、抗性强、病害少、早熟丰产的幼苗。
City eggplant vegetable breeding hotbed has been staying at the old level, the first year of snow planting, planting around the Qingming around the next year, occupied seedbed for months, spent a lot of manpower and material resources. At the same time, to take temperature control of water ways to restrain seedling growth, seedling age is too long, to cultivate the “old seedlings” yield is not high. Furthermore, due to the long rain in January, nursery difficulty, the phenomenon of varying degrees of death and seedling over the years exist, the light dead seedlings rate of 20-30%, severe cases of more than 90%. Vegetable plant breeding is a flourishing new technology in recent years. It is in accordance with the biological characteristics of solanaceous fruit, under the artificial control of the superior environmental conditions, effectively promote seedling growth and development, nurture the emergence of Qi, Miao Zhuang, developed root system , High survival rate, resistance, less disease, precocious seedlings.
