Embodiment 1

[0051] Example 1 (NCs)

[0052] 2nm zero-valent Cu nanomaterials (TEM picture see figure 1 ) as a fertilizer in promoting the application of tomato resistance and yield, comprising the following steps:

[0053] (1) tomato seeds were sterilized in 5% sodium hypochlorite solution for 10 minutes, then rinsed 3 times with deionized water;

[0054] (2) Soak the seeds in deionized water for 4 hours after the disinfection is completed, then put the seeds into a petri dish with damp filter paper, cultivate them under dark conditions in the greenhouse, and spray water regularly every day;

[0055] (3) After cultivating for 5 days, select evenly germinated seeds and transfer them to a 5.0kg soil culture vessel;

[0056] (4) When the tomato seedlings grow to four leaves and one heart, add 1 mg / L 2nm zero-valent Cu nanofertilizer aqueous solution 100 mL / plant dropwise to the roots.

[0057] Parameters such as photosynthesis, roots, yield, etc. were tested during tomato maturity.

Embodiment 2

[0066] Adjust the Cu fertilizer in Example 1 to be 2 μm zero-valent Cu nanomaterials (see the SEM figure Figure 13 ) and Cu ion solution, and other parameters are consistent with embodiment 1, and parameters such as its photosynthesis, antioxidant enzyme, output are tested in tomato maturation stage. The results are shown in Table 1:

[0067] Table 1

[0068]

[0069] Note: (The specific evaluation standard for Cu enrichment is: compared with the control CK, the copper content in the tomato fruit after the nano-Cu fertilizer treatment has a significant increase)

Embodiment 3

[0071] Adjust the application amount of Cu fertilizer in Example 1, the concentration is still 1mg / L, and the application volume is adjusted at 50-150mL / plant. Other parameters are kept the same as in Example 1, and parameters such as photosynthesis, antioxidant enzymes, and yield are tested during tomato maturity. As shown in table 2:

[0072] Table 2

[0073]

[0074] Note: (The specific evaluation standard for Cu enrichment is: compared with the control CK, the copper content in the tomato fruit after the nano-Cu fertilizer treatment has a significant increase)

Abstract

The invention relates to the technical field of nano agriculture, and particularly discloses application of a copper nano-fertilizer to improvement of tomato resistance and yield. The copper nano-fertilizer is a zero-valent Cu nano-material, and the size of the copper nano-fertilizer is 1-10 nm. According to the invention, the tomato resistance can be remarkably improved, aging of tomato leaves is slowed down, photosynthesis is enhanced, root growth and nutrient absorption are promoted, and the tomato yield is increased. Meanwhile, Cu is not enriched in tomato fruits. The Cu-based nano-fertilizer disclosed by the invention has the advantages of greenness and biological safety when being applied to tomato planting.

Description

technical field [0001] The invention relates to the technical field of nano-agriculture, and specifically discloses the application of a copper nano-fertilizer in improving tomato resistance and yield. Background technique [0002] The United Nations DESA predicted in 2015 that the world population will exceed 9.8 billion in 2050, and the demand for food will double the current production. At present, global food production will consume 187 million tons of chemical fertilizers and 4 million tons of traditional pesticides every year, and the usage is increasing year by year. However, the utilization rate of fertilizers and pesticides is only 30% to 50%, and the application of a large amount of chemical fertilizers and pesticides has caused extremely serious environmental problems. Therefore, it is imperative to innovate agricultural technology and explore the sustainable development of agricultural production. [0003] With the rapid development of nanotechnology, novel nan...
