玉米田间试验数据是玉米育种的根本,夏播玉米生长季节内高温高湿干旱等气候集中而且转化快,田间生长发育受外界因素影响大,为保证提供科学准确的田间试验数据,北京德农种业宁津试验站主要采取的关键措施。1精密播种,播后浇水,力保苗齐苗一致夏直播玉米播种的6月中旬,正值20~30℃的高温,玉米种子萌发生长快,出苗的整齐度好坏将直接影
Corn field test data is the basis of corn breeding, summer sowing corn growth season, such as high temperature, high humidity, drought and other climate focus and fast conversion, field growth and development by external factors, in order to ensure scientific and accurate field test data, Industry Ningjin test station to take the key measures. A precision sowing, watering after sowing, the strength of seedlings Miao Qi consistent Summer sowing of corn sowing in mid-June, at a high temperature of 20 ~ 30 ℃, the rapid growth of maize seeds germinate, the emergence of neatness will be direct or direct
