目前,春玉米播种在即,为落实好各项关键技术措施,确保春玉米增产,针对春白地旱情,近日,省玉米专家顾问组提出地膜覆盖、精细播种、合理密植等抗旱保春播技术建议。专家认为,地膜覆盖可提高地温、保蓄土壤水分,提早出苗,加快玉米生长发育进程,是春播区实现玉米高产的重要技术措施。地膜玉米的播种期一般要比大田裸地提早10-15天。采用覆膜种植时要注意播种与覆膜方式的选择,解决好施肥方式及残膜处理等配套技术问题。
At present, the spring corn sowing soon, in order to implement the key technical measures to ensure that spring corn yield increase, the drought for the spring white, recently, the provincial corn expert advisory group proposed mulching, precision sowing, reasonable density and other drought-resistant spring sowing technology recommendations. Experts believe that mulching can increase the ground temperature, soil moisture conservation, early emergence and accelerate the process of corn growth and development, is the spring sowing area to achieve high yield of maize is an important technical measure. The sowing time of maize corn is generally 10-15 days earlier than that of bare land. The use of film planting should pay attention to sowing and coating options, to solve the fertilization methods and residual film processing and other supporting technical issues.
