氮磷用量对天鹰椒产量及氮钙镁养分吸收的影响

通过天鹰椒氮磷肥效应试验研究，建立了大鹰椒产量、单株椒、单椒重及吸收N、Ca、Mg养分数量依N、P2O5用量的回归方程；应用产量回归方程计算出最高产量、最佳经济产量及相应的N和P2O5用量；应用天鹰椒产量、单株椒、单椒重及吸收N、Ca、Mg养分数量依N、P2O5用量的偏回归曲线，说明N、P2O5用量对天鹰椒的影响。

Effect of quantity of nitrogen and phosphorus application to the yield and N, Ca,Mg uptake on cluster redpepper

The effects of nitrogen and phosphorus application on cluster redpepper have been studied though a test. Regression equations of the yield, pepper number per single plant, single pepper weight, quantity of N, Ca, Mg nutrient uptake to quantity of N and P2O5 application were established. Use the equation of the yield, estimated highest and most economic yields. Corresponding the quantity of N and P2O5 application were estimated too. Use partial regression curves of its to quantity of N or P2O5 application. Explain effect of quantity of N and P2O5 application to the Plant.
