春花生超高产栽培技术模式研究与应用

采取正交旋转回归设计,以播种期、种植密度、施肥量为试验因子,以9000kg/hm2为产量目标函数,进行春花生超高产栽培模式集成研究。结果表明,在鲁西南平原地区,超高产春花生以种植密度和N、P、K施肥量为主要限制因素,播种期为次要限制因素。明确了春花生单产达到9000kg/hm2以上的最佳种植密度、播种期和合理的N、P2O5、K2O施用量为主要指标的栽培技术模式,增产效果显著。

Research and Application of the Super High-yield Cultivation Technology Mode in Spring Peanut

Take the rotation regression orthogonal design, with the sowing time, planting densi-ty, fertilizer amount as experimental factors, using 9000kg /ha as the output target function, we stud-ied the integration of super high yield cultivation mode of spring peanut.The results showed that the main limiting factor of super high yield of spring peanut in the southwest plains area of Shandong was planting density and the N, P, K fertilizer amount; the second limiting factor was sowing time.The mode of cultivation techniques of peanut yield of 9000kg /ha with the optimum planting density, sowing date and reasonable N, P2 O5 , K2 O fertilizer as main factors obviously increased the peanut yield.
