1.撤浅水层。及时撤浅水层管理,近期降雨又较多,水田内水层较深,水温、泥温上升缓慢,延迟返青,缓苗重。应立即撤成2厘米左右浅水,促进返青和分蘖。2.科学追肥。根据氮肥总量控制,及时适量追施返青肥。目前仍未追施返青肥的田块应及早追肥,保证养分均衡供应,促进生育;已追施返青肥,但量不足的可在返青后5~7天追施;追施返青肥量较大的田块应避免多次重复追肥,否则容易造成中后期长势过
1. withdraw shallow water layer. The timely withdrawal of shallow water layer management, the recent rainfall and more water paddy deep, water temperature, mud temperature rise slowly, delay back to green, Huanmiao weight. Should be immediately dismantled into about 2 cm shallow water to promote turning green and tillering. 2. Scientific top-dressing. According to the total amount of nitrogen fertilizer control, timely replenishment of green fat. At present, there is no topdressing of green tea fields should be early top dressing to ensure a balanced supply of nutrients to promote fertility; has been chasing back green manure, but less than the amount of green after 5 to 7 days top dressing; The plots should avoid repeated top dressing, or easily lead to growth in the late
