马铃薯是世界上四大种植作物之一。长期以来,在我国除东北和西北等主要产区能够取得较高的产量外,华东、华北及黄淮流域等大部分地区栽培马铃薯的产量难尽人意。事实证明,随着科技的不断发展,新良种的诞生,栽培技术的探索和完善,这些地区完全可以实现高产栽培。一、掌握播种季节,选择早熟品种马铃薯喜冷凉天气,结薯期温度不能过高。如果白天高于28℃,夜间高于23℃,薯块即停止生长。在华东、华北和黄淮流域,由于夏季炎热天气较长,只能采用春秋两季的栽培方式。在这两季
Potato is one of the four crops grown in the world. For a long period of time, the yield of cultivated potatoes in most parts of East China, North China and the Huang-Huai River basin has not been achieved satisfactorily, except for the higher yield in major producing areas such as Northeast and Northwest China. Facts have proved that with the continuous development of science and technology, the birth of new varieties, cultivation techniques to explore and improve, these areas can achieve high-yield cultivation. First, grasp the sowing season, select the early varieties of potato hi cold weather, tuber temperature can not be too high. If the daytime is higher than 28 ℃, at night above 23 ℃, tubers stop growing. In East China, North China and Huang-Huai Valley, due to the hot summer weather is longer, only the spring and autumn cultivation methods. In these two seasons
