玉米的喷灌技术喷灌节水、提高土地利用率，在农业生产中发挥了重大作用。玉米由于植株高大，特别是后期株高都在２米以上，喷灌受到了限制，所以关于玉米的喷灌技术有待进一步地探索。喷灌需要根据作物的各个生育时期的需水量、降水量以及当时地下的含水量而确定灌溉时期...
Sprinkler irrigation technology of corn sprinkler irrigation, improve land utilization, has played a significant role in agricultural production. Due to tall plants, especially in the late plant height of more than 2 meters, sprinkling has been limited, so on the sprinkler irrigation technology to be further explored. Sprinkler irrigation needs to be determined according to the crop’s water requirements at various growth stages, precipitation and subsurface water content at that time ...
