摘 要：
为了探究在光合细菌施用下,生物包衣对油菜生长的影响。以四川油菜主栽品种川油36号为试验材料,采用大田试验,研究了生物包衣(内生芽孢杆菌进行种子包衣,播种前施用光合细菌菌液)、化学包衣(10%氰霜唑悬浮剂进行种子包衣)和未包衣处理对油菜根肿病发生、土壤酶活性变化及产量性状等的影响。结果表明:包衣处理后,油菜根肿病发生率均显著下降,且生物包衣处理下发病率最低。生物包衣处理能显著增强土壤过氧化氢酶、蔗糖酶、脲酶和酸性磷酸酶活性,而化学包衣对土壤过氧化氢酶、脲酶和酸性磷酸酶活性有一定抑制作用。此外,生物包衣处理显著提高了油菜的有效分枝高度、株高、根茎粗、一次性有效分枝数、千粒重和产量,且产量比化学包衣处理和未包衣处理分别提高了16.97%和22.26%。以上结果说明,通过生物包衣和施用光合细菌对油菜土壤环境有良好的改善作用,能有效降低根肿病对油菜的危害,提高油菜产量,同时减少化学药剂的投入。

摘 要：
The study aims to explore the effects of biological coating on the growth of rape under the application of photosynthetic bacteria. The main rape cultivar‘Chuanyou36'in Sichuan Province was used as test material. Based on the field tests, this paper studied the effects of biological coating(endophytic bacillus for seed coating, and application of photosynthetic bacteria liquid before sowing), chemical coating(10%cyazofamid suspension for seed coating) and uncoated treatment on the incidence rate of clubroot, soil enzyme activities and yield traits of rape. The results showed that the incidence rate of clubroot of rape decreased significantly after the coating treatment, and was the lowest under biological coating treatment. The biological coating treatment could significantly improve the activities of catalase, sucrase, urease and acid phosphatase in soil. However, the chemical coating treatment had a certain inhibitory effect on the activities of catalase, urease and acid phosphatase. In addition, the effective branch height, plant height, rhizome thickness, number of primary effective branches, 1000-grain weight and yield of rape significantly increased under the biological coating treatment. Compared with chemical coating treatment and uncoated treatment, the yield of rape with biological coating was increased by 16.97% and 22.26%, respectively. The above results show that biological coating and the application of photosynthetic bacteria could not only improve the soil environment of rape and effectively reduce the harm of clubroot to rape, but also increase the rape yield and reduce the input of chemical agents.
