荣成市地处胶东半岛最东端,受海洋性气候影响,春秋生长季节阴天雾天多,空气湿度大,光照时数少,积温低,是洋葱生产的不利因素,再加上没有适宜的品种,播期及栽培方法不当,使沿海地区洋葱生产迟迟没有发展起来。 1995年以后,我们引进部分新品种进行了试验,初步筛选出适宜本地区栽培的品种,研究出相应的配套栽培技术,使洋葱平均亩产达3500～4000kg,比传统种植增产20%。现将高产栽培技术总结如下: 一、品种选择 1995年品比试验结果表明,红皮洋葱
Rongcheng City is located in the eastern end of the Jiaodong Peninsula, due to the influence of maritime climate, foggy sky over the growing season of spring and autumn, air humidity, light hours, low accumulated temperature is an unfavorable factor for onion production, coupled with no suitable Improper sowing and sowing date and cultivation methods have delayed the development of onion production in the coastal areas. After 1995, we introduced some new varieties to carry on the experiment, and initially screened the varieties suitable for cultivation in this area. We have developed the corresponding cultivation techniques to increase the average onion production to 3500 ~ 4000kg, 20% more than the traditional planting. Now high-yielding cultivation techniques are summarized as follows: First, the variety selection The 1995 ratio test results show that red onions
