免耕马铃薯种植密度与施肥量配套栽培试验初报

Integrated cultivation experiment of no-tillage potato's planting density andfertilization amount

不同种植密度和不同施肥量对免耕马铃薯的产量有很大的影响,为探索马铃薯种植有效密度和科学施肥,进一步提高产量和效益,开展免耕马铃薯种植密度和施肥量的配套栽培试验。试验表明,在合理的施肥水平下,以种植5555丛/667m2,基肥施芬兰星王牌硫酸钾型复合肥15—15—15(S)90kg/667m2的处理产量最高,产量达2492.3kg/667m2。

different planting densities and fertilization amounts have great impact on no-tillage potato yield,so in order to search effective planting density and fertilization and further to increase the yield and benefit,an integrated cultivation experiment of no-tillage potato＇s planting density and fertilization amount was conducted.The results show that under the reasonable fertilization level,the treatment of 5555 cluster /667m^2,base fertilizer of potassium sulfate compound（15-15-15 made in Finland） 90kg /667m^2 has the highest yield of 2492.3kg /667m^2.
