在毛主席的革命路线指引下,我县广大贫下中农,在学习外地经验的基础上,大胆试验薯蔓越冬育秧获得了初步成功。薯蔓越冬育秧的好处是:节约种薯,省工省料;薯秧粗壮,成活率高;能控制黑斑病;便于提纯复壮,保持优良种性。这是甘薯增产的一条新路子。现将我们的具体做法介绍如下: (一)窖型目前较理想的窖型是“简易太阳能温室”。长1丈,宽4尺,深2尺到2.5尺。窖的地上部分的横剖面呈底宽4.5尺,腰长4尺的等腰三角形,北腰用秸秆棚好,用泥抹严,上面留两个气孔;南腰用塑料薄膜罩住。窖址选择地势高燥、背风向阳的地方。床
Guided by Chairman Mao’s revolutionary line, the vast majority of poor and middle-ranking peasants in our county gained initial success on the basis of learning from foreign experiences and boldly experimenting on the winter seedling raising of potato cranks. Potato winter planting benefits: saving seed, labor saving; potato seedling strong, high survival rate; to control black spot; easy to purify and rejuvenate, to maintain good species. This is a new way to increase sweet potato production. Now we introduce the specific practices are as follows: (a) cellar type is currently the ideal cellar type is “simple solar greenhouse.” Length 1 Zhang, 4 feet wide, deep 2 feet to 2.5 feet. The cross section of the upper part of the pit was an isosceles triangle with a base width of 4.5 feet and a waist length of 4 feet. The northern side of the pit was covered with straw shed, with mud stamped, leaving two stomata on it. The southern waist was covered with a plastic film. Select cellar high terrain, leeward sunny place. bed
