摘要:

为探究施肥模式和栽插密度对四川丘区水稻产量及生长的影响,以‘蜀优217’和‘天优湘99’为材料,采用裂区设计,主区为施肥模式,裂区为栽插密度,探究不同处理对四川丘区水稻生长及产量的影响。结果表明,侧深施肥能有效提升水稻产量,不同品种之间存在一定差异,侧深施肥模式下,‘蜀优217’适宜较高的栽插密度,而‘天优湘99’栽插密度过高,穗粒数及结实率大幅下降,成穗率及转运率降低。因此,侧深施肥技术应根据品种特性,确定适宜的栽插密度。

Abstract:

To explore the effects of fertilization mode and planting density on rice yield and growth in hilly area of Sichuan Province, ‘Shuyou 217’ and ‘Tianyouxiang 99’ were used as materials in this study. The main area was fertilization mode, the split area was planting density. The results showed that deep side fertilization could effectively improve rice yield, and there were some differences among different varieties. Under the deep side fertilization mode, ‘Shuyou 217’ was suitable for higher planting density, while high planting density of ‘Tianyouxiang 99’ could cause significant decrease of the number of grains per panicle and seed setting rate, and reduce the panicle rate and transfer rate. Therefore, the appropriate planting density should be determined according to the characteristics of varieties.

Key words: rice, hilly area of Sichuan, fertilization mode, nitrogen fertilizer, density, yield, growth
