摘要:

为了明确烟草残茬还田后对水稻生长和产量的影响,采用盆栽试验,模拟不同的烟草残茬还田方式,检测了水稻分蘖、株高、根系、干物质积累、氮磷钾养分积累动态及产量。结果表明,烟草残茬还田能促进水稻分蘖,增加株高,促进根系发育,增加植株干物质积累量和氮磷钾积累量,提高水稻产量;烟草残茬全量还田、烟草根系还田可分别提高产量17.35%、8.60%。烟草残茬还田有利于水稻生长和产量提高,在烟稻复种区可推广烟草残茬全量还田方式。

关键词: 烟草残茬还田, 水稻生长, 水稻产量, 干物质积累, 养分积累

Abstract:

In order to figure out the effects of tobacco stubble returning on rice growth and yield, pot experiments were conducted to test the dynamic change of rice tillering, plant height and roots, and the accumulation of dry matter, nitrogen, phosphorus and potassium, and the effects on rice yield by simulating different tobacco stubble returning. The results show that tobacco stubble returning could promote rice tillering, plant height and root development, the accumulation of dry matter, nitrogen, phosphorus and potassium, and rice yield. The tobacco stubble total returning and the tobacco root returning could increase the yield by 17.35% and 8.60%, respectively. Tobacco stubble total returning is beneficial to the growth and yield of rice, and it can be popularized in tobacco rice multiple cropping area.

Key words: tobacco stubble returning, rice growth, rice yield, dry matter accumulation, nutrient accumulation
