摘要
介绍了对甘薯新品种“渝薯３４”种植密度和施肥的试验结果，在一般条件下，“渝薯３４”的适宜种植密度为：春薯７５０００株／ｈｍ￣２，夏薯８２５００株／ｈｍ￣２，秋薯９００００株／ｈｍ￣２．其施肥模式是：栽插后１０ｄ施清粪水１５０００ｋｇ／ｈｍ￣２和尿素７５ｋｇ／ｈｍ￣２，栽插后５０ｄ施清粪水２２５００ｋｇ／ｈｍ￣２．栽插后９０ｄ施清粪水２２５００ｋｇ／ｈｍ￣２和草木灰１５００ｋｇ／ｈｍ￣２．
The test results of the planting densities and fertilization quality of the newly-evolved sweet pota-to variety ' Yushu 34' were reported here. In ordinary condition,the planting densities of the varietyare 75 000 plants/hm￣2 for the spring planting,82 500 plants/hm￣2 for the summer planting and 90 000plants/hm￣2 for the autumn planting respectively. The best fertilization patterns are that 15 000 kg/hm￣2diluted animal muck with water and 75 kg/hm￣2 urea fertilizer fertilized in 10 days after planting,22500 kg/hm￣2 diluted animal muck with water fertilized 50 days after planting and 22 500 kg/hm￣2 dilut-ed animal muck with water and 1500 kg/hm￣2 ash fertilizer fertilized in 90 days after planting.
