【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。更多还原

【Abstract】 In order to study the positive effects of composite titanium on crops, this paper used a method of "test-comparison-retestsynthesis(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 by 11.7%-27.3%, and the effects by spraying were greater than those by seeding, with the different value ranging from 4.1%(soybean) to 10.1%(rice).(2) The dry weight of plant roots increased by 8.45%(sweet potato)-22.31%(soybean), and the root volume increased by 6.21%(sweet potato)-11.32%(jujube).(3) The number of soybeans’ rhizobium increased more than 35%.(4) The three factors’ utilization rate increased respectively by 0.63-2.12%(N), 0.68%(P) and 0.72%(K), and the absorption rate increased by 24.6%, 17.8% and 18.5%.(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.更多还原
