摘要： The present disclosure discloses an application method of silicon quantum dots (Si QDs) for controlling corn armyworm, belonging to the technical field of nano-agricultural technology for crop pest control. The method for controlling corn armyworm by using Si QDs of the present disclosure includes the following steps of: preparing the Si QDs into an aqueous solution of the Si QDs, and then applying the aqueous solution on the roots or leaves of plants as plant fertilizer; where the concentration of the aqueous solution of the Si QDs is 10-150 mg/L; the size of the Si QDs is 3-8 nm. The method of the present disclosure not only improves the effect of the conventional silicon fertilizer on the stress resistance of plants, but also directly improves the direct insecticidal effect of the nano-silicon and improves the chemical defense capability of plants; the optimal spraying amount of Si QDs is determined by spraying different concentrations of Si QDs in the growth and development experiment of armyworm.

摘要： The present disclosure discloses a method of promoting rice growth using artificial humic acid synthesized by catalysis of nanoscale Ferric oxide, belonging to the field of nanoscale agriculture. The present disclosure discloses a method for synthesizing artificial humic acid from waste biomass with catalysis of transition metal, including the following steps: adding a mixed solution of an alkali, a transition metal catalyst and water into a biomass raw material, and carrying out catalytic reaction at 160-250° C. for 6-48 hours. The artificial humic acid can accelerate germination of rice, effectively promote growth of the rice (the root activity is improved by 166.76% and the net photosynthetic rate is improved by 72.08%), improve the absorption of water and nutrients and the transport of nutrients by rice roots and improve the ability of rice to resist oxidative stress and salt stress.

摘要： The disclosure discloses application of nanosulfur in tomato fusarium wilt control, belonging to the technical field of novel pesticides. The application of the disclosure includes the following steps: preparing a nanosulfur solution from nanosulfur; and then soaking seeds in the nanosulfur solution or applying the nanosulfur solution onto tomato foliage, and continuing cultivation to obtain tomato plants. The nanosulfur has a particle size of 20-150 nm. The nanosulfur solution uses water as a solvent and has a concentration of 30-200 mg/L. According to the disclosure, after the tomato plants are treated with the nanosulfur by foliar spraying, the fresh weight of the above-ground part is 1.05 times or more that of the disease group, and the fresh weight of the underground part is 1.05 times or more that of the disease group, so that the incidence of tomato fusarium wilt is reduced by 8% or more. After the tomato plants are treated with the nanosulfur by seed soaking, the fresh weight of the above-ground part is 1.38 times or more that of the disease group, and the fresh weight of the underground part is 1.05 times or more that of the disease group, so that the incidence of tomato fusarium wilt is reduced by 20% or more.
