地膜甘薯栽培技术是以地膜覆盖为核心,配套精细整地、科学施肥、适期早播等措施的甘薯高产稳产综合栽培技术。一般增产40%～50%,并且提前15～20天成熟。现将其丰产栽培技术要点概述如下。1适宜范围适宜无霜期短、有效积温不足的地区。盖膜后能有效提高地温,增加积温,提高土壤抗旱保墒能力,增产效果显著。
Plastic film sweet potato cultivation technology is based on plastic film as the core, supporting the preparation of fine land, scientific fertilization, early sowing and other measures of sweet potato high-yielding comprehensive cultivation techniques. The general increase of 40% to 50%, and mature 15 to 20 days in advance. Now its high yield cultivation techniques outlined below. 1 suitable range Suitable frost-free period is short, the effective area of insufficient accumulated temperature. After covering the membrane can effectively improve the ground temperature, increase accumulated temperature, improve drought resistance ability of soil moisture, yield a significant effect.
