养猪积肥是一项重要肥料来源。水浮莲是一种很好的养猪青饲料。1972年,我所和卧龙公社光明大队农科所进行了水浮莲的采种和种子越冬贮藏方法的试验,于1973年3月20日在温室里催芽,观察发芽势和发芽率。 试验结果说明:(1)采种时期以10月下旬较好,比11月中旬采摘的种子提早发芽5—9天,发芽率高18—41％。早采的种子由于开花早,温度较高,种子成熟得好,发芽率高。(2)采种方法以洗根收集的棕褐色种子较好,比摘果得到的青绿色种子提早发芽4—6天,发芽率高25％。因为,附着 Pigging fertilizer is an important source of fertilizer. Water lettuce is a good pig feed. In 1972, we and the Wolong commune Brigade Agricultural Sciences conducted a test of waterfowl seeds and seeds overwintering storage method, in March 20, 1973 germination in the greenhouse to observe the germination potential and germination rate. The results showed that: (1) The seed-collecting period was better in late October than the seeds picked in mid-November, germinating 5-9 days earlier and the germination rate was 18-41% higher. Early harvest seeds as early flowering, high temperature, the seeds mature well, the germination rate. (2) Seeding method The tan seeds collected by root washing are better than the turquoise seeds obtained by picking fruit, germinating 4-6 days earlier and the germination rate is 25% higher. Because, attached
