| 摘 要： | 本文通过对大田苜蓿实施不同的施肥处理,研究施肥对紫花苜蓿产量和营养吸收规律的影响。对苜蓿三年的株高进行整理,应用Logistic方程y=k/(1+aebx)对苜蓿株高进行分析,得到苜蓿植株的最大增长速率、最大增长速率出现的天数和品均增长速率。结果表明,处理1(尿素97.8kg/ha,过磷酸钙293.5kg/ha,硫酸钾136.4kg/ha)的株高最大,该处理在每年第二茬植株最大增长速率、平均增长速率最大、植株最大增长速率出现的天数最短:通过对苜蓿干草产量、氮磷钾吸收量、含量进行分析,所得的结论与株高基本一致。

| Abstract: | Field experiment was conducted to investigate different amount of fertilizer on yield and nutrition absorption of alfalfa crop in the medium fertilizer soil.This study wants to research the effect of fertilizer on alfalfa yield and nutrition absorption. Based on three years yields and plant heights of the alfalfa,we can obtain the highest increased rate(HIR) of plant height,appearance time of HIR and the average growth rate by using the logistic equation,y=k/ (1+aebx)and binary quadratic equation.Result indicated that the optimum rate of P and K to obtain the highest yield,the highest increase rate of plant growth and its earlier appearance,and highest average growth rate was 1 treatment in the second batch every year.Based on three years yield,nutrition absorption and nutrition content of the alfalfa,we can obtain the proper combination of phosphorus fertilizer,potassium fertilizer were phosphorus fertilizer 293.5kg/ha, potassium fertilizer 136.4kg/ha. |
