马铃薯垄作密植综合配套栽培技术

Technology of Ridge Culture Combined with High Density Planting Package for Potato Production

针对丽江市马铃薯生产上普遍存在的种植密度稀、耕作层浅、偏施氮肥、不防治病害、管理粗放、产量低而不稳等问题,开展了种植密度、不同肥料及施用量、晚疫病药剂筛选防治等试验,总结出了以优良品种的脱毒种薯小整薯播种,深耕、高垄密植、增施磷钾肥、防治晚疫病、充分使用农机为主要内容的马铃薯垄作密植综合配套栽培技术,并在较大范围示范推广,对提高马铃薯产量发挥了积极的作用。

In the traditional potato production of Lijiang, the yield was low and unstable because of low planting density, shallow cultivable layer, excessive use of nitrogen fertilizers, extensive management and so on. In recent years, a lot of trials have been done, such as planting density, fertilizers and application rate, screening of fungicide for control of potato late blight to solve the above-mentioned problems. Based on the experimental data, the technology of ridge culture combined with high density planting package were put forward, including using improved cultivar, planting whole virus-free seed tuber, deep ploughing, high rate application of phosphorus and potassium fertilizer, late blight control, and using farm machinery available. This technology has been used extensively on large scale and achieved good results.
