适合马铃薯+中稻+再生稻熟制的冬种马铃薯栽培方式探讨

Study on the Cultivation Methods of Winter Potato which Suitable for Potato + Medium Rice + Ratoon Rice Cropping

为筛选适合马铃薯+中稻+再生稻熟制的冬种马铃薯优质、早熟、高产、高效的种植方式,比较分析了6种马铃薯栽培方式的生育进程、成苗和块茎状况及产量。结果表明:翻耕-条播-全程地膜栽培、翻耕-条播-前期覆膜栽培和免耕-条播-盖草-前期覆膜栽培3种栽培方式产量高,可与中稻+再生稻熟制衔接,为适合马铃薯+中稻+再生稻熟制的冬种马铃薯高产栽培方式。考虑到翻耕-条播-前期覆膜栽培和免耕-条播-盖草-前期覆膜栽培覆盖的膜能够全部撤出,不会导致稻田白色污染,且马铃薯商品性好,此两种栽培方式适合马铃薯+中稻+再生稻熟制区大面积推广应用。

In order to screening high quality, early maturing, high yield and high efficiency planting methods for winter potato that suitable for ＂potato ＋ medium rice ＋ ratoon rice＂ cropping, six potato cultivation methods were used in this study with randonfized block design,potato growth process, seedling,tuber status and yield under various cultivation methods were analyzed comparatively. The results showed that the three cultivation methods, plowing - drilling - plastic film mulching cultivation during whole growth period, plowing - drilling - film mulching cultivation prelinfinary, and no tillage - drilling - Straw mulch - film mulching cultivation prelinfinary, produced high yields and was suitable for linking with ＂potato ＋ mediunl rice ＋ ratoon flee＂ cropping. Considering that the covered mulching film of plowing - drilling - film mulc-hing cultivation preliminary and no tillage - drilling - Straw mulch - film mulching cultivation preliminary could be completely withdrawn, which would not cause white pollution in paddy field and had good marketability of the potato, so, the two cultivation methods were suitable for large - scale popularization and application in potato ＋ medium rice ＋ ratoon rice cropping area.
