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 on the planting density and fertilization of a new sweet potato variety “Yu-shu 34” were introduced. Under normal conditions, the suitable planting density of “Yu-shu 34” was 75000 plants per hectare and 82500 plants per hectare ~ 2, autumn potato 90000 plants / hm ~ 2. The fertilization mode is: after planting 10d clear manure water 15000kg / hm ~ 2 and urea 75kg / hm ~ 2, after planting 50d clear manure 22500kg / hm ~ 2. After planting 90d Shi Qing manure 22500kg / hm ~ 2 and Ash 1500kg / hm ~ 2.
