为了解决大白菜上市淡旺不匀,延长大白菜的供应季节,我们根据南方冬季气温多变的特点,作了既要防冻又要防暖的两手准备,从1970年开始,采取了室外堆垛,架空覆盖,通风保暖的贮藏方法,获得了较好效果。四年来共贮藏大白菜300多万斤,并降低了大白菜的损耗率(一般为15％左右,最低为9.8％)。一、选好地块选择通风保暖、土粒较粗、排水良好的地块。堆垛之前先确定堆的位置,一般堆长17-33尺左右,宽4-4.5尺,南北向,拉绳定界,挖成高的畦子,两边挖好深沟,将畦上的土搞碎、耙平、拍板。畦与畦间留2尺左右距离,作为走道和水沟之用。二、选择品种贮藏用的品种以选耐贮
In order to solve the inconsistent Chinese cabbage market, to extend the supply of cabbage season, we have the characteristics of the changing cold temperatures in the south, made both anti-freezing and anti-warming preparations, from 1970 onwards, taken the outdoor stacking , Overhead coverage, ventilation and warm storage methods, get better results. Over the past four years, more than 300 kilograms of Chinese cabbage has been stored and the loss rate of Chinese cabbage has been reduced (usually about 15% and the lowest is 9.8%). First, select the site selection Ventilation warm, coarse soil particles, well-drained plots. Prior to stacking to determine the location of the pile, the general length of 17-33 feet long, 4-4.5 feet wide, north-south, drawstring boundaries, digging into high prickly heat, dug deep trench on both sides, Broken, rake flat, clapper.畦 and 畦 left about 2 feet between the distance, as a walkway and ditches. Second, select varieties of varieties used to choose Storability storage
