在早春茬果菜类生产上,常在寒冬季节进行育苗,这时气温低,光照不足,再加上连续阴雪雾天气常有发生,这些不利的天气条件对培育健壮的蔬菜苗子带来了很大的麻烦。那么,在生产上怎样克服这种不良环境条件呢?下面,介绍六点应对措施,提醒广大菜农注意。一、选好育苗场。要选择日光温室的中部地带为育苗场地,因为中部温度比山墙两侧的温度高2—3℃,育苗时需要较高的温度,这样可以有效避免秧苗遭受冷害。严冬季节育苗,应采取地热线育苗的方法,苗床上还可以再扣上一小拱棚来保温。还要注意育苗床要有足够的营养面积,防止秧苗拥挤造成徒长。
In early spring crop fruit and vegetable production, often in the cold season nursery, when the temperature is low, lack of light, coupled with continuous Yin Xue fog often occur, these unfavorable weather conditions to nurture the robust vegetable seedlings brought very Big trouble. So, how to overcome this adverse environmental conditions in the production of? Here, introduce six response measures to remind the majority of farmers attention. First, choose a hatchery. To select the solar greenhouse in the central area for nursery grounds, because the central temperature than the gable sides of the temperature 2-3 ℃, raising the need for higher temperatures, so you can effectively prevent chilling injury. Winter season nursery, geothermal breeding methods should be taken, the seedbed can also be re-attached to a small shed to insulation. Also pay attention to nursery bed to have adequate nutrition to prevent seedling crowded cause leggy.
