2种自动滴灌施肥系统在规模化园区草莓育苗上的应用效果

针对草莓育苗灌水次数多、用水用工多的问题,以单棚文丘里人工滴灌施肥为对照,研究2种自动(全自动和半自动)滴灌施肥系统控制多棚草莓育苗的灌水、施肥的用工、灌水量、灌水次数、繁苗系数以及繁苗质量等指标。结果表明:对于规模化园区,全自动施肥机和半自动滴灌施肥处理分别比常规对照省工86%和32%,省水36%和24%,繁苗数量分别提高7.9%和2.9%,同时草莓繁苗质量好,根茎粗和主根数都增加,有利于草莓苗的成活。因此,对于30个棚以上的规模化园区推荐使用全自动施肥机,对于5~12个棚的小规模园区推荐使用半自动滴灌施肥处理系统。

Application Effects of Two Automatic Fertigation Systems on Strawberry Seedling in Scale Park

In order to solve the problem of frequent irrigation and excessive use of water and labor in strawberry matrix seedling,the application effects of two automatic fertigation systems were studied in the strawberry seedling nursery production scale park with conventional venturi fertigation method as control and the labors,water amount,propagation seedlings coefficient and quality were investigated.The results showed that compared with the control,the full-automatic fertigation treatment and the half-automatic fertigation treatment of strawberry seedling could save water by 36% and 24%,save labor by 86% and 32%,and improve the number of propagation seedlings by 7.9% and 3.2%.At the same time,the strawberry propagation seedlings quality was very good,the number of strawberry seedling new roots and the diameter of seedling stem were higher,which was good for the survival of seedlings.Therefore,it was recommended to use full-automatic fertigation system for large-scale parks with more than 30 greenhouses,and half-automatic fertigation treatment system for small-scale parks with 5-12 greenhouses.
