水稻是汉中最重要的粮食作物,常年种植160多万亩,占粮食作物播种面积的27％左右,产量为粮食总产的52％以上。过去在水稻生产中,抓单项技术多,综合配套不够,不能充分发挥各项措施的增产效应。水稻规范化(模式化)栽培技术研究,就是针对上述问题,根据农业系统工程原理,采用多元回归正交旋转组合设计方法,以秧龄、插秧密度、施氮、磷、有机肥的水平为决策变量,1984—1986年在汉中盆地不同类型地区、不同土壤类型、不同肥力水平条件下设
Rice is the most important food crop in Hanzhong. More than 1.6 million mu of perennial crops have been planted, accounting for about 27% of the sown area of food crops. The output is above 52% of the total grain output. In the past, in rice production, grasping individual technologies and comprehensive support was not enough to give full play to the stimulation effect of various measures. Rice standardization (modeled) cultivation technology research, is to address the above problems, according to the principles of agricultural systems engineering, the use of multiple regression orthogonal rotation combination design method to seedling age, transplanting density, nitrogen, phosphorus and organic fertilizer levels as the decision- From 1984 to 1986 in different types of Hanzhong Basin, with different soil types and different fertility levels
