叶面喷施含氨基酸水溶肥料在辣椒和豇豆上的肥效

Effects of Foliar Spraying of Water Soluble Fertilizer Containing Amino Acids on Growth of Pepper and Cowpea

以辣椒(苏椒5号博士王)和豇豆(夏杰)为材料,研究叶面喷施利用废弃猪毛研制的含氨基酸水溶肥料在辣椒和豇豆上的应用效果。本试验分两季进行,设3个处理:不喷施任何肥料(CK1)、喷施清水(CK2)和喷施含氨基酸水溶肥料(AA)。田间试验结果表明:对辣椒和豇豆叶片喷施含氨基酸水溶肥料能有效促进辣椒和豇豆植株的生长,提高辣椒和豇豆果实的品质,同时叶面喷施含氨基酸水溶肥料还改变了辣椒和豇豆种植土壤中可培养微生物的数量。与不喷施、喷施清水处理相比,喷施含氨基酸水溶肥料显著提高了辣椒和豇豆的产量。从第一季看,辣椒的增产幅度分别为12.0%和10.8%,豇豆的增幅分别为10.3%和8.9%;从第二季看,辣椒的增幅分别达到13.5%和12.5%,豇豆的增产幅度分别是18.9%和14.7%,与第一季相比,第二季增产幅度有所提升。由此,利用废弃猪毛研制的含氨基酸水溶肥料叶面喷施能够有效促进设施辣椒和豇豆的产量,研究结果可为废弃猪毛的资源化利用和设施蔬菜的高效栽培提供理论依据。

A field experiment with two seasons were conducted in order to investigate the effects of foliar spraying of water soluble fertilizer containing amino acids（WSA） on the growth of pepper and cowpea. The pepper variety（Su-Jiao no. 5-Dr. Wang） and cowpea variety（Xia-Jie） were chosen as the tested plants. Three treatments were designed, i.e., no spraying（CK1）, spraying with water（CK2）, and spraying with WSA（AA）. The results showed that AA treatment improved the growth and quality of pepper and cowpea, significantly enhanced the yields of pepper and cowpea, and meanwhile altered microbial quantities in soils. Compared with CK1 and CK2, AA treatment increased pepper yield by 12.0% and 10. 8% in the first season and by 13.5% and 12.5% in the second season, respectively; while increased cowpea yield by 10.3% and 8.9% in the first season and by 18.9% and 14.7% in the second season, respectively; and the increase amplitude in the second season was higher than in the first season. The above results demonstrate that foliar spraying of WSA produced by wasted pig hair could enhance the yields of pepper and cowpea, which is helpful for the resource utilization of pig hair and efficient cultivation of greenhouse vegetables.
