摘要
虾肽氨基酸叶面肥因富含活性氨基酸、甲壳素、虾红素、虾脑磷脂、壳聚糖及微量元素,可在全面供给作物营养的同时,有效提高作物的抗病虫害能力。试验以沙糖桔为材料,从农艺性状变化、抗病虫害能力、产量以及经济效益方面分析了喷施虾肽氨基酸叶面肥对沙糖桔的影响,结果显示:虾肽氨基酸叶面肥可有效促进沙糖桔叶片增大增厚,增加果实茎粗和重量,提高成花座果率;显著提高沙糖桔对病虫害的抵抗能力(害螨发生率减少了37.5%,病害种类减少了33.3%),黄化树发生率降低77.8%;沙糖桔增产18.6%,投入产出比为1∶13.9,经济效益显著。
Shrimp peptide amino acid foliar was rich in active amino acid, chitin, astaxanthin, shrimp cephalin, chitosan and microelement, could effectively increase crop resistance to pests and diseases while comprehensively supplying plant nutrients. Shatang citrus was used as experimental material, effect of shrimp peptide amino acid foliar fertilizer on shatang citrus was analyzed in aspect of changes in agronomic traits, pest-resistant capacity, yield and economic benefits. Result showed that shrimp peptide amino acid foliar fertilizer effectively promoted shatang citrus blade increasing and thickening, increased the fruit stem diameter and weight, improved fruit set percentage as well as significantly improved the shatang citrus resistance to pests and diseases （the mite incidence decreased by 37.5%, the disease species decreased by 33.3%）. Etiolated tree incidence decreased by 77.8%. The yield of shatang citrus increased by 18.6%. The input-output ratio was 1：13.9. The economic benefit was significant.
