摘要: 【目的】 研究裸地和覆膜处理与不同播期组合对旱稻生长、养分吸收及产量的影响。【方法】 采用田间试验,设置裸地和覆膜2个处理,每处理3个播期,即4月15日(早播)、5月1日(适播)、5月15日(晚播),旱稻品种选用旱香1号、旱香2号,分析旱稻的干物质重、养分吸收及产量。【结果】 覆膜处理旱稻干物质重、养分吸收及产量均显著高于裸地处理,分别高出14.7%~19.5%、8.8%~54.2%和18.4%~24.0%。不覆膜条件下,晚播干物质重、养分吸收及产量均显著高于早播,分别高出17.5%~22.1%、23.3%~55.0%和71.7%~85.1%。覆膜条件下,适播处理干物质重、养分吸收及产量最高,较早播和晚播分别增加9.0%~18.0%、7.5%~30.3%和3.6%~24.8%。【结论】 旱稻在覆膜和适播条件下,有利于旱稻生长和养分吸收,并提高产量,为最佳的栽培模式。

Abstract: 【Objective】 The field experiments were conducted to study the effects of bare land, plastic film mulching and different sowing dates on growth, nutrient uptake and yield of upland rice.【Methods】 Two treatments of bare land and plastic mulch were set up, and the three sowing dates of each treatment were April 15 (early sowing), May 1 (suitable sowing), and May 15 (late sowing). The dry matter weight, nutrient absorption and yield of upland rice were analyzed by using upland rice varieties Haxiang 1 and Haxiang 2.【Results】 The dry matter weight, nutrient uptake and yield in film mulched upland rice treatment were 14.7%-19.5%, 8.8%-54.2% and 18.4%-24.0% higher than those in bare land treatments respectively. The dry matter weight, nutrient uptake and yield in late sowing treatment were 17.5%-22.1%, 23.3%-55.0% and 71.7%-85.1% higher than those in early sowing treatments respectively. Under the plastic film mulching treatment, the dry matter weight, nutrient uptake and yield of suitable sowing treatment were the highest, which were increased by 9.0%-18.0%, 7.5%-30.3% and 3.6%-24.8% in early and late sowing respectively.【Conclusion】 Under the conditions of plastic film mulching and suitable sowing, upland rice is the best cultivation mode for its growth, nutrient uptake and yield.

Key words: upland rice; sowing date; plastic film mulching; nutrient uptake; yield
