遵照伟大领袖毛主席“备战、备荒、为人民”的教导,去年,我们进行番薯藤苗越冬繁殖试验,看来只要管理得当是完全能够越冬,越冬苗通过苗旺苗也可以培育出粗壮藤苗。这是解决番薯育苗用种量大,容易烂种等问题的有效措施。影响番薯生长的主要因素是温度,一般认为温度在10℃时,藤苗就停止生长,如果遭到霜冻就会死亡。因此,在越冬苗床中能否保持一定的温度是藤苗能否安全越冬的关键。同时 In accordance with the teachings of Chairman Mao, the great leader, “preparing for war, preparing for war and for the people,” last year we carried out trials of overgrowth of sweet potato vine seedling. It seems that as long as we manage properly, we can fully wintering. . This is to solve the sweet potato seedling with large quantities, easy to rot and other issues of effective measures. Affect the growth of sweet potato is the main factor in the temperature, the temperature is generally believed that the 10 ℃, the seedling stopped growing, if frost will die. Therefore, in the winter seedling can maintain a certain temperature is the key to the survival of vine seedlings can be safe. Simultaneously
