几年来的实践证明,要获得油菜高产,就必须培育壮苗。为达到此目的,我们初步认为应抓好如下环节。一、种子“好种出好苗”,种子的质量好坏,直接影响到秧苗的素质。据我们试验,同一品种,只晒不选比不晒风车选的,出苗率高2%,单株鲜重和干重分别高0.76克和0.19克;晒后经盐水选的,比不晒风车选、不晒盐水选,只晒不选和晒风车选的,千粒重高0.2—1.7克,出苗率高
Practice over the past few years proved that to get rapeseed, we must nurture strong seedlings. To achieve this goal, we initially believe that we should do the following. First, the seeds “good kind of good seedlings,” the quality of the seeds of a direct impact on the quality of seedlings. According to our test, the same species, only the sun is not selected than the non-drying sunbeds selected, the emergence rate of 2%, fresh weight and dry weight of 0.76 grams and 0.19 grams, respectively; after sun selected by the brine than the non-drying windmill Election, not sun salt election, only the sun is not selected and sunbeds selected, one thousand grain weight 0.2-1.7 grams, high emergence rate
