摘要
为探索贵州省生产上鲜食甘薯的高产栽培技术,对不同品种、不同的施肥比例、不同栽培密度进行了试验。结果表明:凯里红苕的产量排第二,但是中薯比例最大,其鲜食价值更高;采用N 4 kg、P 2 kg、K 4 kg、Ca 1 kg的配比产量较高,适当增施钾肥可提高块根产量,适当施用钙肥可以增强甘薯植株对逆境的抵抗力;在肥力中等的田块,栽培凯里红苕以4 000株/667 m2最佳。
In order to explore the production of Guizhou Province,fresh sweet potato cultivation techniques,different varieties,different fertilization ratio was tested with different planting densities.The results showed that the production of sweet potato carey was second,but the largest proportion in the number of potato,the higher the value of its fresh;using N 4 kg,P 2 kg,K 4 kg,Ca 1 kg had higher the ratio of output,appropriately increase potassium fertilizer root production,the appropriate application of calcium can enhance resistance to adversity;in the field with secondary fertility,cultivation the best planting density was 4 000 plants per 667 m^2.
