1.鳖地作畦 选择地下水位低的高岸田或排灌较好的热土栽植,耕作层以15厘米～20厘米为宜,过深薯块易伸长或变形。不宜在过酸的土壤和低洼地栽植。耙松整平,作畦,畦宽2米左右,每畦两厢,中间一条走道,每畦4行,畦高25厘米～30厘米,以利排水。为夺取高产,应重视基肥,特别要施钾肥,如火土灰、复合肥、氯化钾,也可用腐熟优质土杂肥(干的)。每667平方米用土杂肥2吨,复合肥50公斤或氯化钾30公斤,或草木灰l000公斤～2000公斤,过磷酸钙50公斤拌匀作基
1. turtle for 畦 choice of high groundwater level shoal or drainage irrigation better soil cultivation, tillage layer to 15 cm to 20 cm is appropriate, too deep potato easy to stretch or deformation. Should not be too acid in the soil and low-lying planting. Rake loose leveling, for 畦, 畦 width of about 2 meters, each 畦 hatchback, the middle of a walkway, every 畦 4 lines, 畦 high 25 cm to 30 cm, to facilitate drainage. In order to seize high yields, emphasis should be placed on basal fertilizer, especially potassium fertilizer, such as fire ash, compound fertilizer, potassium chloride, can also be used to decompose high-quality Tuza Fei (dry). Every 667 square meters with Tuza 2 tons, 50 kg of fertilizer or potassium chloride 30 kg, or ash l000 kg ~ 2000 kg, 50 kg of superphosphate mix well for the foundation
