玉米是山东省高唐县的主要粮食作物之一,种植面积占粮食作物的48%,产量占粮食总产的55%,玉米产量是保障全县农业丰收的关键。近年来,全县玉米生产逐渐实现了从中产到高产,再由高产向更高产的飞跃。特别是在粮食高产创建、配方施肥、“一防双减”等项目的示范带动下,涌现了一大批超高产典型。但随着玉米产量由高产向更高产飞跃,玉米倒伏面积逐渐扩大,并呈现迅速蔓延之势。如何解决高肥水地块玉米高产与倒伏的矛盾,成了
Maize is one of the main grain crops in Gaotang County, Shandong Province. The acreage accounts for 48% of the total grain crops and the output accounts for 55% of the total grain output. Maize yield is the key to ensure the agricultural harvest in the entire county. In recent years, the county corn production gradually realized from middle class to high yield, then from high yield to higher yield leap. Especially in the high yield of grain, formula fertilization, “a double” and other projects under the guidance of a large number of super-high-yield typical. However, with the corn yield leaping from high yield to higher yield, corn lodging area gradually expanded and showed rapid spread. How to solve the contradiction between high yield and lodging corn in high fertilizer block has become
