1.加强中耕铲趟。出苗前耢一遍,提高地温兼有灭草作用。出苗后及时查田补种。全生育期三次铲趟,特别是东部地区,以利散墒提温,时间分别在苗高2厘米深趟、苗高10厘米浅趟和现蕾封垄前深趟,同时适当加厚培土。人工除草为主,化学除草每公顷90%禾耐斯,80克加70%塞克2克,播后苗前施药。2.加强肥水管理。马铃薯发棵期、盛花期肥水条件要充足。结薯初期,要适当控水分,少浇水或不浇水;结薯期,即当块茎长至2~3厘米时,是马铃薯需肥、需水量最大时期,要适时灌水、追肥。追肥以钾
1. Enhance the cultivation shovel trip. Pre-emergence 耢 again, improve both temperature and herbicide effect. Post-emergence check Tian Tian replanting. The whole growth period of three shovel trips, especially the eastern region, to facilitate the bulk moisture temperature, respectively, 2 cm seedling height trip, seedling height of 10 cm shallow trip and budding seal ridge deep before the trip, while appropriate thickened earth. Artificial weeding-based, chemical weed 90% per hectare Wo Neissez, 80 grams plus 70% 2 grams Sec, sowing before spraying after spraying. 2. To strengthen fertilizer and water management. Potatoes hair stage, full bloom flowering conditions to be adequate. At the beginning tuber, it is necessary to control the water, less watering or not watering; tuber, that is, when the tubers grow to 2 to 3 cm, the potato needs fertilizer, the maximum water demand period, to be timely irrigation, dressing.
