一、为什么要进行冬培?“冬培”是苎麻冬季管理的简称。苎麻是多年生宿根作物,是以地下茎和根越冬的。因此搞好麻地的冬季管理,保护地下部分安全越冬,壮大地下茎,促使地下茎多孕芽、孕壮芽,就成为苎麻生产中的重要一环。苎麻越冬对温度有一定的适应范围,在表土5厘米以下地温5℃以上时,苎麻的地上茎仍然继续生长、孕芽;当地温降到5℃以下,地下茎生长即暂时停止,处于休眠状态;土温继续下降到2℃,地下茎幼嫩部分便开始受冻害,这种低温延续时间长,整个麻蔸也要受冻害,造成弱蔸或缺蔸。据宜春地区气象站资料,我区历史上极 First, why do winter training? “Winter training” is the abbreviation of winter ramie management. Ramie is a perennial perennial crop that overwinters underground stems and roots. Therefore, Matilda winter management to do to protect the underground part of the safe winter, grow underground stems, prompting underground stems more than buds, pregnant strong buds, has become an important part of ramie production. Ramie winter over the temperature have a certain range of adaptation, in the top soil temperature below 5 centigrade above 5 ℃, ramie aboveground stems continue to grow, pregnant buds; local temperature dropped below 5 ℃, underground stem growth that is temporarily stopped in a dormant state; soil The temperature continued to drop to 2 ° C and the tender parts of underground stems began to be frostbite. This low temperature extended for a long time and the whole mochi also suffered frost damage, causing weakness or lack of heat. According to Yichun meteorological station data, our district history extremely
