人参经过秋冬季的休眠,在春季土壤平均温度达到5℃时便开始萌动,8℃时缓慢出土,10℃以上为出苗盛期。能否保证人参春季出苗整齐及以后健壮生长,春夏季的田间管理是关键。1.早春排水.冬雪多的年份,早春要注意参田排水。防止参床土壤湿度过大,温度低,影响出苗及导致菌核病发生。要趁冻清理作业道上的积雪,尤其注意清理背坡参地上的积雪。2.松土消毒.当参床土壤化冻而又不粘重时,可以去掉防寒土。床面平整后可用400倍液代森铵进行土壤消毒。防治小苗病害可用800倍液敌克松进行喷雾。每10平方米喷洒药液5公斤。喷药后马上进行松土,最好三项作业相继进行。松土深度仅限于根上部覆土层,千万不要移动参根。3.架设参帘.一般采用一层塑料薄膜、一层花
Ginseng after autumn and winter dormancy, in the spring when the average soil temperature reached 5 ℃ began to germinate, slowly unearthed at 8 ℃, 10 ℃ or more for the emergence of seedlings. Ginseng can guarantee the emergence and tidy spring ginseng growth after the spring and summer field management is the key. 1. Early spring drainage. Winter snow and more years, early spring to pay attention to field drainage. Prevent bed soil humidity is too large, low temperature, affecting emergence and cause sclerotinia. To clear the snow on the road when using frozen, with particular attention to clean up the back slope of the snow on the ground. 2. Soil sterilization. When the soil into the soil thawing and not sticky, you can get rid of cold soil. After the bed surface can be 400 times the liquid ammonia soil disinfection. Disease control seedlings available 800 times the enemy liquid Nixon spray. Spray liquid 5 kg every 10 square meters. Rinsing immediately after spraying, the best three operations have been carried out. Loose soil depth is limited to the upper soil cover, do not move the root. 3. Erection of the Senate curtain.General use of a plastic film, a layer of flowers
