摘要: 为了探索更加清洁高效的水稻覆膜栽培技术,采用小区试验的方法,研究可降解地膜代替常规地膜、一次性施用不同用量的控释氮肥,与“中稻 再生稻”的最佳结合技术。结果表明:覆膜后降解地膜与普通非降解地膜覆对再生稻两季产量影响差异不显著。控释肥一次性基施以150 kg N/hm2处理头季稻产量最高,225 kg N/hm2处理“中稻 再生稻”两季总产最高。因此,水稻覆膜技术与可降解地膜、控释肥以及再生稻技术结合后,是一项清洁、高产、高效的水稻栽培新技术。

Abstract: The objective is to explore cleaner and more efficient rice film mulching cultivation technology. The plot experiment method was carried out to study the optimal combination of the degradable mulching film replacing conventional plastic film, one-time application of different dosages of controlled release fertilizer with“middle-season rice ratoon rice”. The results showed that the effect of degradation mulching film and ordinary non-degradable film on the yield of two-season rice was not significantly different. The yield of main crop under the treatment of 150 kg/hm2 N was the highest using controlled-release fertilizer by single basal application, while the total yield of the middle-season rice ratoon rice reached the maximum at 225 kg/hm2 N. Therefore, the new rice cultivation technology involving degradable mulching film, controlled-release nitrogen fertilizer and ratoon rice is a clean one which could achieve high-yield and high-efficiency.
