摘要:
以板栗为研究对象，通过氮、磷、钾三因素三水平肥料试验，建立了三元二次关于板栗产量的施肥模型。结果表明：氮、磷、钾肥对板栗均有增产效应。单一元素施肥时，施肥上限：氮肥1.61 kg/株、磷肥1.56 kg/株、钾肥1.66 kg/株。板栗施肥存在NK、NP、PK互作效应。二元施肥时，氮钾肥配合使用N∶K2O=0.8∶1.0，氮磷配合施用N∶P2O5=0.8∶1.0，最大用量为1.8 kg/株；磷钾配合使用P2O5∶K2O=0.35∶0.4,最大用量为0.75 kg/株。N、P、K最大施肥量为每株 N 1.543 kg、P2O5 1.349 kg、K2O 1.288 kg，目标产量4.61 kg。
Abstract:
With Castanea mollissima BL as materials，the yield of chestnut on different NPK fertilizers were studied.Model of characteristics graph relations that the one nutrient and two nutrient effect to Chinese chestnut’s yield were analyzed.The results showed that all can increased yield of the chestnut it were nitrogen and phosphorus and potassium.Maximum amount of fertilizers：the nitrogen 1.61 kg per tree；the phosphorus 1.56 kg per tree;the potassium 1.66 kg per tree.It had nutrition interaction effect it was the nitrogen and potassium，the nitrogen and phosphorus，the phosphorus and potassium between for the chestnut.N∶K2O=0.8∶1.0.Maximum amount of fertilizers：the nitrogen 0.8 kg per tree and potassium 1.0 kg per tree；It added to 1.8 kg per tree.N∶P2O5=0.8∶1.0.Maximum amount of fertilizers was 1.8 kg per tree.P2O5∶K2O=0.35∶0.4.Maximum amount of fertilizers was 0.75 kg per tree.Maximum amount of fertilizers of the nitrogen and phosphorus and potassium was the N 1.543 kg per tree，P2O5 1.349 kg per tree，K2O 1.288 kg per tree.It was yield of intent 4.61 kg.
