地处我省西部的安达市,首次采用甜菜地膜覆盖新技术,获得亩产3660公斤,含糖16.52％的好收成。安达市为了扭转甜莱生产上的被动局面,责成糖厂专题研究地膜覆盖这一技术措施,终于为治理“双低”闯出了一条新路。它的显著特点之一是:试验证明,在早春盖膜后,如晴天,地温平均比对照田增温2.6℃,5厘米土层达5.1℃,10厘米地温增值达5.3℃,地面最低温度平均增值1.5℃。这样,有效地防止早春低温对甜菜幼苗的危害。据试验:甜菜出苗比对照提前4天,出苗率提高27％,5月10日调查,覆膜的甜菜幼苗株高18.1厘米,较对照高2.7厘米,幼苗百株重2300克,比
Is located in the western province of Anda City, the first time using sugar beet mulching of new technologies, access to 3660 kg per mu, sugar 16.52% good harvest. In order to reverse the passive situation in the production of sweet and salads, Anda ordered the sugarcane project to study the technical measures of mulching and finally broke a new road for the management of “double low”. It is one of the salient features of this experiment. Experiments show that in the early spring, the average ground temperature is 2.6 ℃ higher than that in the control field, 5.1 ℃ in 5 cm soil layer, 5.3 ℃ in the 10 cm soil layer, and 1.5 ℃ in the lowest ground surface temperature ℃. In this way, effectively prevent the early spring low temperature on the sugar beet seedlings harm. According to the experiment: the emergence of sugar beet four days earlier than the control, the germination rate increased 27%, May 10 investigation, covered beet seedling height 18.1 cm, 2.7 cm higher than the control, seedling weight 2300 grams,
