摘要
通过总结数十年来湖南省各地不同农作物在不同种植制度下,不同用量、用期、用法施用复合钛剂的试验结果,对农作物施用复合钛剂的正效应进行了探讨。结果表明:(1)复合钛剂喷施或拌种,均能提高植物叶片的叶绿素含量,提高幅度11.7%~27.3%;复合钛剂用于农作物,喷施的正效应大于处理种子,其差异值4.1%(黄豆)~10.1%(水稻)。(2)复合钛剂替代生长素,植物根系干重增加8.45%(红薯)~22.31%(黄豆),根系容积增加6.21%(红薯)~11.32%(枣)。(3)黄豆用复合钛剂喷施或拌种,根瘤菌数增加35%以上。(4)农作物施用复合钛剂,N、P、K利用率分别提高0.63%~2.12%、0.68%、0.72%,吸收速率分别提高24.6%、17.8%、18.5%。(5)复合钛剂降解生成的物质在环境中大量存在,其使用不会污染土壤和环境。综合来看,复合钛剂性能稳定、吸收利用率高、促生性好、显效性强,且无残留、无污染,具有广阔的应用前景。
In order to study the positive effects of composite titanium on crops,this paper used a method of“test-comparison-retest-synthesis(promotion)”,summarized the past a few decades’experimental results of the application of the composite titanium with different plants,different planting systems,different amounts,different periods and different methods in Hunan Province,and thus obtained the following results:(1)The application of composite titanium by spraying or by seed dressing increased the chlorophyll content of plant leaves by11.7%-27.3%,and the effects by spraying were greater than those by seeding,with the different value ranging from4.1%(soybean)to10.1%(rice).(2)The dry weight of plant roots increased by8.45%(sweet potato)-22.31%(soybean),and the root volume increased by6.21%(sweet potato)-11.32%(jujube).(3)The number of soybeans’rhizobium increased more than35%.(4)The three factors’utilization rate increased respectively by0.63-2.12%(N),0.68%(P)and0.72%(K),and the absorption rate increased by24.6%,17.8%and18.5%.(5)Due to the existence of a large number of composite titanium degradable substances in the environment,the application of it will not pollute the soil and the environment.In conclusion,the composite titanium agent has a broad application prospect for the advantages of stable performance,high absorption efficiency,good properties,strong effect,zero-residue and zero-pollution.
