摘要
植物对氨基酸的吸收、转运、代谢以及氨基酸在肥料和农药上的应用国内外已有报道。已有研究证明,植物可直接吸收土壤中的氨基酸分子,其吸收后的转运、分配、代谢因氨基酸种类而异,产生的生理效应也不相同;氨基酸农药易被日光分解或被自然界微生物降解,在土壤中、植物体内不留残毒,其降解产物还可作为农作物的营养物质,提高农作物的品质和产量,施用这类农药,人畜安全,没有公害;氨基酸肥具有促进植株生长发育、增强抗逆性、改善土壤状况和提高作物产量的作用。
It has been reported that the researches of uptake, transport, metabohsm of amino acids by plants and application of amino acid on fertilizers and pesticide at home and abroad. Amino acids in soil can be utilized directly, but the differences of uptake, transport, metabolism and physiology effects showed in plant because of different amino acids. Amino acid can easily be decomposed by sunlight or degradated microorganism. And it does not keep a poison remnant in soil and plant Its degradation product can also serve as crop nutrients and improve the quality and yield of crops. The application of such pesticidesis is safe for people and animals. Amino acid fertilizers can promote crop growth, strengthen resistance, improve soil conditions and increase crop yields.
