鉴于用有边秧筛进行无泥育秧耗费木材、钉子,成本高、易变型等缺点,我局同黄石公社金洪大队涨水生产队在试验推广无泥育秧的过程中,试验无边秧筛套育成功。我们在无泥育秧及水产养殖厂内进行了3次试验,第一次于1977年4月中旬,第二次在8月中旬,第三次在9月下旬,都获得成功。无边秧筛套育的方法是:利用质轻易浮,筛眼较大(15目左右)的塑料窗纱布(市场有卖的),剪成与木边筛同样大小一块平铺在木边筛上,播种套育,待种谷扎根竖针现第二叶时,将平铺的筛网纱布连苗一
In view of the disadvantages of using seedling-free seedlings such as timber, nails, high cost and mutability, the Bureau of Yellow River Brigade and Jinhong Brigade inundated production team tried to promote the seedless seedling-growing process. Successful education. We conducted three trials in a mud-free seedling and aquaculture plant, the first in mid-April 1977, the second in mid-August and the third in late September. Borderless seedlings Nesting method is: the use of quality easily floating, large screen (15 mesh or so) plastic window gauze (the market has sold), cut into the same size with a wooden edge tile tiled on the wood edge sieve , Sowing sets of breeding, planting seedlings to be rooted when the second leaf is now, the tile mesh gauze with a tile even
