目前各地育苗多采用冷床或电热温床,但难度大、技术性强、各有利弊,近年来我们将冷床与电热温床相结合,取两者之长,补两者之短,在大棚内进行两步育苗,取得满意效果,现将该技术介绍如下: 第一步冷床播种育苗。选择自然温度尚能满足茄果类蔬菜种子正常发芽生长的10月下旬至11月上中旬进行冷床播种,完全不加电热,秧苗也能正常生长发育,这时温度适中,湿度也低,很少有病害发生,秧苗生长缓慢、节间短、健壮。 At present, more nursery around the use of hot bed or electric hotbed, but difficult, strong technical, each has its own advantages and disadvantages, in recent years we will be hot bed and electric hot bed combination of both long, make up the short of both in the greenhouse Two-step nursery, and achieved satisfactory results, the technology is introduced as follows: The first step cold-bed sowing seedlings. Select the natural temperature is still able to meet the normal germination and growth of eggplant vegetable seeds from late October to mid-November on a cold bed sowing, no electric heating, the seedlings can grow normally, when the temperature is moderate, the humidity is low, very Few diseases occur, seedlings grow slowly, internodes short, robust.
