摘　　要：天然橡胶的胶清中含有丰富的营养物质,其中N、P、K、Ca、Mg等矿物元素和蛋白质、氨基酸等都是植物生长所必需的。本研究通过白菜发芽试验、幼苗试验以及苋菜土培试验,对胶清液在农业方面的应用进行了探究,初步验证了天然胶清基农业生物制剂的资源特性。试验表明,在适宜浓度下,胶清可以促进小白菜种子的萌发和幼苗的生长,提高苋菜的品质和口感,促进苋菜对土壤中营养物质的吸收,调节土壤pH,改良土壤状况。本研究对天然胶乳的分层次全利用和胶清生物制剂的开发有一定的研究意义。Latex skim of natural rubber contains redundant nutrients, including mineral element such as N, P, K, Ca, Mg, protein and amino acid, which are essential for plant growth. This study explored the application of latex skim in the aspect of agriculture, and preliminarily verified the resource behavior of latex skim agricultural biological agents through seed germination rate experiment, seeding growth experiment and soil culture experiment. The results showed that latex skim could promote the Chinese cabbage seed germination rate and seeding growth, improve the quality and taste of edible amaranth, promote the absorption of nutriments for edible amaranth, adjust the pH, and improve the soil in appropriate concentration. This study is significant for layering utilization of natural latex and developing latex skim biological agents.
