新植蔗栽培耕作技术对宿根蔗产量和品质影响的研究

就新植蔗9种不同栽培耕作技术对宿根蔗产最和品质的影响进行研究，结果表明，新植蔗不同栽培耕作技术不仅对新植蔗的产量和品质有显著影响，而且对宿根蔗的产量和品质也有较高程度的后效。新植蔗处理横直深松再覆盖地膜和处理横直深松再覆盖蔗叶，有利于促进宿根蔗的生理生化代谢过程，有利于有效茎数和单茎重的增加，有利于糖分的积累，从而提高宿根蔗的产量，改善宿根蔗的品质，在生产上具有一定的推广应用价值。

Study on the Effects of Different Cultivation Practices of Plant Cane on Yield and Quality of Ratoon Cane

The effects of 9 different cultivation practices of plant cane on the yield and quality of the ratoon cane were studied. The results showed that the different cultivation practices of plant cane not only have significant effects on the yield and quality of plant cane, but also have deeply continuous effects on the yield and quality of ratoon cane. The Two-way Deep Soil Loosening + Plastic Film Mulching and the Two-way Deep Soil Loosening + Leaf Mulching practices of plant cane can improve physical and chemical metabolism, increase the number of millable stalk and the cane height, enhance the accumulation of the sucrose content of ratoon cane. The yield and quality of the ratoon cane were therefore improved, showing considerable application value.
