氮磷用量对天鹰椒产量及氮钙镁养分吸收的影响

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

通过天鹰椒氮磷肥效应试验研究,建立了天鹰椒产量、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。

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.
