水稻省肥高产栽培是以宽行窄株、插足基本苗的密植方式,“山”字形施肥技术(分次接力),“多露轻晒”的水浆管理为主要内容的一套完整栽培法。它不是孤立的技术措施,而是各种技术措施相互配合,在争取一定穗数的基础上,主攻大穗夺取高产。总的要求是在水稻营养生长期,促进地下根系发育良好,地上部份有一定长势,壮而不过旺,营养够吃不过量,防止大升大降,使禾苗稳健生长,根强秆壮而不徒长,叶厚直而不垂弯,叶色青翠而不浓绿,群体密而不
High-yielding cultivation of rice is a set of complete cultivation method with the main contents of narrow-width plantings, close-planting of basic seedlings, “mountain” shape fertilization technology (relay by weight) and water slurry management of " . It is not isolated technical measures, but a variety of technical measures complement each other, for a certain number of spikes on the basis of the main big ears to seize high yield. The general requirement is that in the period of rice vegetative growth, it promotes the underground root system to develop well, the aboveground part has a certain growth potential, strong and not prosperous, enough nutrition to prevent it from rising and falling greatly, making the seedling grow steadily, the root is strong and strong Not only lenient, Ye Hou straight but not vertical, leaf color green rather than dark green, dense population
