花生品种粤油79不同密度及不同施肥量试验

The experiment of new variety of peanut——Yueyou No.79 by different planting density and manuring

运用二因素三水平随机区组方法探索粤油 79栽植密度及N、P2 O5、K3O的施用量与产量间关系。结果表明 :选用栽植密度为 2 0 0 0 0粒 (6 6 7m2 ) - 1 ,N :P2 O5:K2 O =1:0 .5 :1.5、施N量 4kg(6 6 7m2 ) - 1 、施P2 O5 量 2kg(6 6 7m2 ) - 1 、施K2 O量 6kg(6 6 7m2 ) - 1 时可获最佳产量。

Using method of random group (zone) of two factors and three levels to study the relationship between planting density,N,P2O3,K2O manuring amount and the yield of Yueyou No.79. The result shows that when selecting planting density as 20,000 granules/(667 m2)-1,N: P2O3: K2O=1: 0.5: 1.5,N manuring as 4kg/(667 m2)-1,P2O3 as 2kg/(667 m2 )-1,K2O as 6kg/(667 m2 )-1,the optimum yield can be achieved.
