摘要
在云南旱地上，改传统春植为秋植，在秋植规范栽培技术下，对秋植甘蔗下种量、行距、施氮、施磷、施钾五个重要因素采用二次通用旋转组合设计试验，建立秋植甘蔗栽培数学模型，根据试验示范蔗区不同生产条件，筛选出公顷单产８２．５～９０ｔ、９０～９７．５ｔ、９７．５～１０５ｔ三个产量层次的模式技术供生产示范推广。
This research studied transforming traditional spring-planting to autumnplanting in Yunnan upland. By used routine autumn-planting cultivation technologies, the tests emphasized on relationship of seeding rate, row-space, N, P and K fertiizer by means of general rotatory design, and established high-yielding sugarcane cultivation models. Then according to the different cultivation condition of different paradigmatic areas, selected the technological models of three input standard: 82. 5-90t/ha, 90-97.5t/ha, 97. 5-105t/ha.
