Studies on Optimization Scheme of High Yield Planting Technics of New Peanut Variety Puhua 3

Through experiment designed by the orthogonal rotation regression method of 5 factors(planting density,pure nitrogen,K2O,CaO,P2O5),the results showed: the 5 factors influencing the yield of Puhua 3 successively was planting densityCaOpure nitrogenK2OP2O5;the best optimization grouping scheme which could make the yield of Puhua 3 exceed 4500kg/hm2 was the base seedlings 2.6271×105～2.7369×105/hm2,pure nitrogen 149.46～153.21kg/hm2,P2O5 87.48～91.05kg/hm2,K2O 177.66～181.32kg/hm2 and CaO 56.04～57.87kg/hm2.
