本试验采用田间单因素随机区组设计,研究了加施坡缕石对紫花苜蓿生长及产量的影响。结果表明:坡缕石用量750～3 000kg/hm2时,均能提高紫花苜蓿的产量和品质,3 000kg/hm2时产量最高、植株最高,且粗蛋白质、赖氨酸含量也最高,品质最优。这一研究结果在紫花苜蓿栽培中科学合理的将N、P、K肥料与坡缕石配施是提供了科学依据。
In this experiment, single-factor randomized field design was used to study the effects of adding palygorskite on the growth and yield of alfalfa. The results showed that the yield and quality of alfalfa could be increased with the dosage of palygorskite from 750 to 3 000 kg / hm2, the yield and quality of alfalfa increased at 3 000 kg / hm2, the highest yield, the highest crude protein and lysine content, the best quality . The results of this study provide a scientific basis for the scientific and rational application of N, P, K fertilizer and palygorskite in alfalfa cultivation.
