一、追肥防早衰基肥充足,植株生长健壮的田块,每667平方米(1亩)用尿素150克、磷酸二氢钾200克、红糖250克对水50千克叶面喷施,或者喷施天达2116植物生长营养液(植物细胞膜稳态剂)等提高马铃薯抗逆能力,防止早衰。植株瘦弱,叶片发黄,呈明显脱肥的田块,要及时追肥,每667平方米施尿素10千克,硫酸钾10千克,磷肥20~25千克,有条件的地方,可结合灌水,进行冲施,同时喷施天达2116植物生长营
First, top-dressing anti-premature aging Foundation adequate, robust plant growth plots, every 667 square meters (1 acre) with urea 150 grams, 200 grams of potassium dihydrogen phosphate, brown sugar, 250 grams of water on the 50 kg foliar spray, or spray days 2116 plant growth nutrient solution (plant cell membrane stabilizer) to improve potato resistance to prevent premature aging. Plant thin, yellow leaves, was significantly off the field of plots, to timely top dressing, urea per 667 square meters 10 kg, 10 kg of potassium phosphate, 20 to 25 kg of phosphate fertilizer, where conditions can be combined with irrigation, the red Shi, spraying at the same time up to 2116 plant growth camp
