Problems solved by technology

Similarly, when acidic zinc ions are mixed with basic pesticides such as Bordeaux mixture, lime sulfur mixture, and turpentine mixture, the effectiveness of zinc and pesticides will decrease accordingly.

Embodiment 1

[0026] The method for regulating and controlling the zinc content of soaking liquid of the present invention to improve seed germination is realized through the following steps:

[0027] a. Disinfection: Soak crop seeds with 5% to 15% volume concentration of disinfectant for 20 to 50 minutes, rinse with deionized water, and obtain sterilized crop seeds;

[0028] b. Dip zinc: use 0.1~3mmol·L -1 The chelated zinc soaks the sterilized crop seeds prepared in step a for 16-40 hours, and the seed treatment is completed.

Embodiment 2

[0030] The method for regulating and controlling the zinc content of soaking liquid of the present invention to improve seed germination is realized through the following steps:

[0031] a. Disinfection: Soak crop seeds with 10% volume concentration disinfectant for 30 minutes, rinse with deionized water, and obtain sterilized crop seeds;

[0032] b. Zinc dipping: use 0.5~2mmol·L -1 Soak the sterilized seeds prepared in step a for 20-30 hours to complete the treatment of the seeds.

Embodiment 3

[0034] The method for regulating and controlling the zinc content of soaking liquid of the present invention to improve seed germination is realized through the following steps:

[0035] a. Disinfection: select corn seeds with the same size and plumpness, soak them in 10% NaClO disinfectant solution for 30 minutes, rinse them with deionized water several times, after soaking for 10 minutes, rinse them with deionized water until they are clean;

[0036] b. Dip zinc: then use 0.5mmol L -1 Soak the sterilized crop seeds prepared in step a for 24 hours to complete the seed treatment.

Abstract

The invention provides a method for promoting seed germination through regulating and controlling the content of zinc in soaking liquid and relates to a seed treatment method. The method is implemented by the following steps: a, soaking crop seeds with disinfection fluid with a volume concentration of 5-15 percent for 20-50 minutes and thoroughly washing with deionized water to obtain a disinfected crop seeds; b, soaking the disinfected crop seeds obtained in the step a with chelated zinc of 0.1-3 mmol.L<-1> for 16-40 h, so as to complete seed treatment. According to the method for promoting the seed germination through regulating and controlling the content of zinc in the soaking liquid, provided by the invention, the absorption and the utilization of zinc of a plant are facilitated, and meanwhile, antagonistic action among elements can also be avoided; through regulating and controlling the content of zinc in the soaking liquid, the promoting effect of zinc on the seed germination is judged from the perspective of seed germination, growth, and changes in protective enzyme activity. Through the seed soaking treatment with zinc, the situation that the plant growth is affected due to soil zinc deficiency is improved while the soil pollution caused by excessive application of zinc fertilizers in a farmland is avoided.

Description

technical field [0001] The invention relates to a treatment method for seeds, in particular to a method for regulating and controlling the zinc content of soaking liquid to improve seed germination. Background technique [0002] Zinc (Zn) can promote the growth and development of human body, animals and plants. Since zinc cannot be directly synthesized in the human body itself, but can only be obtained through nutritious food intake, eating more zinc-rich foods can fundamentally and effectively prevent zinc deficiency in the human body. However, the zinc content in soil in my country is generally 3~790μg·g -1 Between, the average content is 100μg·g -1 about. The zinc content in soil is not only closely related to the soil type, but also affected by the soil parent material. The zinc content in the same type of soil will have a large difference due to the difference of the soil parent material. Among them, the zinc content in the acidic soil in the south of my country is...
