甘薯藤尖越冬作种的管理分为冬前期、越冬期和早春期。从做床栽苗起,到候平均气温下降到10℃止称冬前期。冬前期的管理是甘薯藤尖越冬的基础工作。基础打好了,管理省工,越冬成活率高;基础未打好,管理费工,成活率低。总结历年来的经验,冬前期应做好以下工作。一、做好苗床(一)选好床址:甘薯藤尖必须栽在既能保温又能透光的越冬床内才能安全越冬。选择床址是一个非常重要的问题。群众说,床位选好了,一冬床温高;床址选择不当,冬管花劳力,费物资,还保不住温,薯苗死亡率高。做越冬床的地方要合乎三个条件:一是光照充足,二是床内水分排得走,三是床温保得住。丘陵山区在座北朝南,背风向阳,前无树荫,后无来水的
Sweet potato rattan tip overwintering for species management is divided into winter, winter and early spring. Starting from the bed planting seedlings, waiting for the average temperature dropped to 10 ℃ only known as the winter before. Pre-winter management is sweet potato rattan overwintering foundation work. Basic lay, management of labor, winter survival rate is high; the foundation is not laid, management fees, low survival rate. Summarizing the experience of the past years, the following work should be done in the early winter. A good seedbed (a) choose a good site: Sweet potato rattan must be planted in both the insulation and translucent winter bed can be safe and wintering. Choosing a site is a very important issue. The masses said the beds were selected, a winter bed temperature is high; inappropriate choice of beds, winter tube flower labor, materials, but also keep warm, high mortality rate of potato seedlings. Do overwintering bed place to meet the three conditions: First, adequate sunshine, and second, the water is discharged in the bed, and third, the bed warmth to live. Southern hilly mountain seat south, leeward sunny, no shade before, after no water
