不同时期喷施叶面肥对紫花苜蓿生长和、产草量营养品质的影响
|
摘要
试验以种植第二年的‘东农1号’紫花苜蓿(Medicago sativa L.‘Dongnong No.1’)为试验材料,一年收割三茬,利用自主研制的紫花苜蓿专用叶面肥(专利申请号:201810124670.2)分别在每茬紫花苜蓿刈割前第30天、第25天、第20天、第15天、第10天、第5天进行喷施,以不喷施作为对照,研究不同时期喷施叶面肥对紫花苜蓿生长、产草量和营养品质的影响。结果表明:第一茬紫花苜蓿叶面肥最佳喷施时期为刈割前第15天,第二茬和第三茬紫花苜蓿叶面肥最佳喷施时期均为刈割前第20天。对三茬紫花苜蓿生长性状、产草量、营养品质和相对饲用价值综合分析,叶面肥最佳喷施时期为刈割前第20天。
The second year of planting Medicago sativa L.‘Dongnong No.1'was used as experimental material,which was harvested three times in one year.In addition,a slef-made alfalfa foliar fertilizer(patent application number:201810124670.2)were sprayed on 30 days,25 days,20 days,15 days,10 days,and5 days before each mowing,respectively.The alfalfa was not sprayed was used as a control,the effects of spraying foliar fertilizers on the growth,grass production and nutritional quality of alfalfa were studied.The results showed that the best spraying period of alfalfa foliar fertilizer in the first stubble was the 15 th days before mowing,and the best spraying period of alfalfa foliar fertilizer in the second and the third stubble was the 20 th day before mowing.Analysis of growth traits,grass production,nutritional quality,and relative feeding value of alfalfa,the results suggested that the best spraying period of foliar fertilizer was 20 days before mowing.
