玉米是一种喜温、喜光、生长期短的高产作物,对肥料的反应很敏感,合理施肥的增产效果很显著。目前生产上常因施肥不合理或肥料不足,产量还很低。为了发挥玉米的增产潜力,提高单产,必须了解玉米的需肥特性,针对玉米生长发育规律对营养元素的要求及环境因素对玉米吸收养分的影响,合理增施肥料。 Corn is a hi-temperature, hi light, short growing season of high-yield crops, the reaction is very sensitive to fertilizers, a reasonable yield increase effect is significant. At present, production is often due to unreasonable fertilization or insufficient fertilizer, the yield is still very low. In order to exert the yield potential of corn and improve the yield, it is necessary to understand the characteristics of fertilizer required for corn. According to the requirements of corn growth and development rules on nutrients and environmental factors on the nutrient absorption of corn, fertilizers should be added rationally.
