[目的]针对泸糯12号播种期和种植方式对高粱农艺性状的影响进行研究。[方法]采用裂区试验，直播和移栽为主处理，不同播种期（3月25日、4月5日、4月15日、4月25日、5月5日）为副处理，研究泸糯12号的生育期和产量及其相关性状的变化。[结果]泸糯12号在川东南直播的产量比移栽要略高，且差异达显著水平但未达极显著水平。直播的生育期要比同期育苗移栽的生育期略短，差异达极显著水平。直播的产量相关性状株高、茎粗均高于育苗移栽，且均达到了显著差异。泸糯12号的产量以5月5日播种最高，其次为3月25日播种。[结论]泸糯12号在川南以3月下旬和5月上旬直播可高产且省工省时。

According to Lu Nuo 12 sowing date and planting patterns, the influence on Sorghum agronomic was studied. [Method] With split plot experiment design the main treatment were direct seeding and transplanting and sub-treatment was different sowing time (3/25, 4/5, 4/15, 4/25, 5/5). The change of Lu Nuo 12 growth period and yield and its related traits were studied. [Result] The results showed that yield of direct seeding in Southeast slightly higher than transplanting significantly but not significant level. Growth period of direct seeding was shorter than the same period growth period of transplanting with the difference reached significant level. The direct seeding yield traits of height, stem diameter were higher than transplanting. The highest yielding of Lu Nuo 12 was May 5th seeding, then the March 25th. [Conclusion] Therefore, the best seeding time of Lu Nuo12 in the south of Sichuan was late March and early May ,which could save labor and time.
