为适应蔬菜生产现代化,急需改进现行育苗技术.一、改进加温方式目前,鞍山蔬菜育苗多采用温室地上生火加温.这种方式先提高气温再提高地.温由于外界气温低,床土湿度大、导热快,地温不易升高,秧苗根系生长缓慢而地上茎叶徒长.为了控制徒长又错误地控水、控温.结果是苗龄过长,秧苗老化早衰(蕃茄的苗龄80天,是适龄的两倍.辣椒苗龄110天,茄子90天,大棚黄瓜60天).严重影响蔬菜的丰产和优质.
In order to adapt to the modernization of vegetable production, the urgent need to improve the current nursery technology.An improved heating method At present, Anshan vegetable nursery more use of greenhouse ground fire heating.This way first raise the temperature and then increase the temperature due to the outside temperature is low, bed soil humidity Large, fast heat conduction, the ground temperature is not easy to increase, the growth of the root system of the seedling slow and dry stems and leaves on the ground in order to control leggy and mistakenly control the water, temperature control.The result is the seedling age is too long, seedling aging premature aging (tomato seedling age 80 days, Is twice the age. Pepper age of 110 days, 90 days eggplant, greenhouse cucumber 60 days). Seriously affect the vegetable yield and quality.
