为解决黄花菜生产的种源问题,我们从1982年9月开始,在我县长春公社新堤嘴大队黄花场进行了黄花菜切片育苗试验。8批切片培苗,成活率都在95%以上,证明黄花菜切片育苗是成功的。其具体做法是:一、切片的时间和温度黄花菜属百合科多年生宿根作物,发芽高峰是在立秋后的半月内和翌年清明节前后,在这两个季节前后进行黄花莱切片育苗,成活率高。我们于1982年9月24日切片,当时日平均气温26℃,旬平均气温24℃,3—4天出苗,7天左右萌发新根,成活率在95%以上,1983年4月9日移栽到大田,亩产干花10斤左右。由此看出,黄花菜切片育苗最适时为8月下旬到9月底。10月以后切片育苗的,不但成活率低,而且移栽到大田后要推迟一年投产。二、切片操作和排苗方法母本种苗的选择,应
In order to solve the provenance problem of day lily production, we started from September 1982, in Changchun commune Xintizui Brigade Huanghua field lily seedling nursery trials. 8 batches of nursery stock, survival rates are above 95%, prove nursery lily slicing is successful. The specific practices are: First, the time and temperature sliced lily lily perennial perennial crops, sprouting peak is half a month after the establishment of autumn and the following year before and after the Ching Ming Festival, before and after the two seasons of yellow flower seedlings, survival High rate. We sliced on September 24, 1982, when the average daily temperature was 26 ℃, the average temperature was 24 ℃ for 3-4 days, germination on 3-4 days and germination of new roots about 7 days, the survival rate was above 95%. On April 9, 1983, Transplanting to the field, about 10 kg per mu of dried flowers. This shows that nursery lily sliced the most suitable time for the end of August to the end of September. Slice seedlings after October, not only the survival rate is low, and transplanted to the field to postpone production for one year. Second, slicing operation and method of seedling selection of seedlings should be
