水稻灌浆期是决定产量的关键时期,田间管理应以养根保叶、防止早衰、提高光合效率、促进灌浆、提高结实率和粒重为目标。一、补施粒肥看苗、看田、看天施用粒肥。叶色偏黄、剑叶短小的应补施,叶色浓绿、剑叶肥大的不施;瘦田补施,肥田不施,晴天多的补施,阴雨天多的不施。一般在破口期每667平
Rice filling stage is the key period for yield control. Field management should aim at raising leaves, preventing premature aging, improving photosynthetic efficiency, promoting grain filling, improving seed setting rate and grain weight. First, fill fertilizer to see Miao, see Tian, see the use of grain fertilizer days. Leaf color yellow, the short leaves should be supplemented, dark green leaves, the sword leaves hypertrophy do not apply; lean Tian Fu Shi, fertilization Tian Shi Shi, sunny days and more Shi Shi, rainy days and more do not apply.
