玉米是我市主要粮食作物,近几年有发展的趋势,其中以麦(蚕豆)茬套种春玉米为主要种植方式。为了充分发挥春玉米的增产潜力,我们对不同生产水平的苏玉1号和丹玉6号进行了大田调查,结合多年多点的高产栽培试验,分析麦茬套种春玉米产量构成因素之间的关系,进而提出配套栽培措施。 (一)单产与构成因素的关系 我们从环境、生产条件基本一致的100多块玉米田中,取具有代表性的61块田数据进行统计分析,籽
Corn is the main food crop of our city, and there is a trend of development in recent years. Among them, wheat (broad bean) stubble spring maize is the main planting method. In order to give full play to the yield potential of spring maize, we conducted field surveys on different production levels of Suyu 1 and Danyu 6, and analyzed the relationship between the yield components of spring maize intercropping with the multi-year high-yielding cultivation experiment , And then put forward supporting cultivation measures. (A) the relationship between yield and composition factors We basically from the environment, production conditions are more than 100 pieces of corn field, take a representative of the 61 field data for statistical analysis
