轉作田玉米生育特性及肥培管理(I)子實收量之期作間和土瓖間差異及有關因素

Abstract

本試驗在臺中縣霧峰（本所）及雲林縣二崙比較臺農351號玉米在秋作和春作對氮肥用量和栽值密度之效應，及肥料深施的效果，以闡明高產之栽培條件，N x spacing experiments were conducted at Wu-feng (TARI) and Erh-lun (about 30 Km south-west of TARI) to study the effects of levels of N and spacing (70×25 and 70×20cm) on dry matter production and yield of corn during 1983-1984 fall and 1984 spring crop seasons. In addition to the factors of N and spacing, the treatments at Wu-feng covered another factor, i. e., in-row subsoiling and deep placement of fertilizer versus conventional method of fertilization. The effects of the deep placement were further tested in the fall crops of 1984 and 1985.
