梨早春育苗技术研究

在大连地区,以西洋梨品种Spalding为试材,采用初冬播种、早春顶凌播种和温室营养钵育苗3种不同方式育苗,研究早春最佳育苗技术。结果表明:早春顶凌播种在成苗率和平均苗高方面略高于温室营养钵育苗,但明显高于初冬播种;早春顶凌播种在苗木质量方面明显优于另外2种方式,并且错开农时,节省大量人、财、物。

Study on the Early Spring Seedling Technique of Pear

This paper studied three cases presenting the seedling cultivation of European pear the Spalding on early winter seeding,early spring sowing in ice crust and greenhouse nutrition pot seeding in Dalian.The results showed that the seeding rate and average seedling height of early spring sowing in ice crust were a little higher than that of nutritional bowl seedling in green house,but were obviously higher than the early winter seeding.The seedling quality of early spring sowing in ice crust was the best of th...
