蔬菜无土育苗就是营养液代替土壤,并在人工控制的综合环境条件下进行育苗的方法。此法不仅可以缩短苗龄,提高秧苗质量,杜绝病害,降低育苗成本,而且能促使蔬菜早熟高产优质,提高经济效益,值得当前大力推广应用。现将其育苗技术介绍如下: 一、基质准备 备好基质是无土育苗的关键环节之一,应选择通气性良好,保水性强,酸碱度适宜(pH值在6.5～7.0之间)的材料作基质。如细碎炉渣、草炭、炭化稻壳、炭化玉米秸秆等均可作为育苗基质,可单独使用,也可等量混合使用。
Vegetable soilless seedling is nutrient solution instead of soil, and under artificial control of the integrated environmental conditions nursery methods. This method not only can shorten the seedling age, improve the quality of seedlings, eliminate diseases, reduce the cost of nursery, but also promote the high yield and quality of vegetables, improve economic efficiency, it is worth vigorously promote the application. Now its seedling technology is as follows: First, the matrix preparation Ready matrix is one of the key aspects of soilless seedlings, should choose good aeration, water retention, pH (pH value of 6.5 to 7.0) between the material Matrix. Such as crushing slag, peat, carbonized rice husk, carbonized corn stalks can be used as nursery substrate, can be used alone, but also the same amount of mixed use.
