Embodiment 1

[0044] A method for applying foliar selenium fertilizer to promote cherry radish expansion and nutrient accumulation, comprising the steps of:

[0045] (1) Cherry radish seeds were sterilized in 5% sodium hypochlorite solution for 10 minutes, then rinsed with deionized water 3 times for disinfection;

[0046] (2) Soak the seeds in deionized water for 4 hours after the disinfection is completed, then transfer the seeds to a 5.0kg soil culture container, and spray water regularly every day;

[0047] (3) When the seed seedling grows and reaches the stage of two leaves and one heart, the Se fertilizer (particle size 60nm, particle size 60nm, figure 1 ) solution 70mL;

[0048] (4) Continue to cultivate, and harvest small radishes after 60 days.

[0049] The test results are as follows: radish root auxin ( figure 2 ) and cytokinins ( image 3 ) synthetic genes were significantly expressed; cambium cells increased ( Figure 4 ); photosynthesis increased by 34.0% ( Figure 5 ); c...

Embodiment 2

[0051] The sizes of the selenium nanomaterials in Example 1 were adjusted to be 30 and 80nm respectively, and other parameters were kept the same as in Example 1 for testing.

[0052] The test results are shown in Table 1:

[0053] The test result of table 1 embodiment 2

[0054]

Embodiment 3

[0056] The application volume of the selenium nanomaterials in Example 1 was adjusted to 30, 100 and 150 mL / strain respectively, and the other parameters were kept the same as in Example 1 for testing.

[0057] The test results are shown in Table 1:

[0058] The test result of table 2 embodiment 3

Abstract

The application method of the foliar selenium fertilizer for promoting expansion of the cherry radishes and accumulation of the nutrient substances comprises the following steps: (1) disinfecting cherry radish seeds in a 5% sodium hypochlorite solution for 10 minutes, and then washing the cherry radish seeds with deionized water for 3 times for disinfection; (2) after disinfection is completed, soaking the seeds in deionized water for 4 hours, then transferring the seeds into a 5.0 kg earth culture vessel, and spraying water regularly every day; (3) when seed seedlings grow out and a two-leaf and one-core period is reached, spraying 70 mL of a Se fertilizer solution with the concentration of 10 mg / L to leaf surfaces; and (4) continuing to cultivate, and harvesting the radishes after 60 days. According to the invention, the upper expression of a plant hormone synthesis gene can be regulated and controlled, and differentiation and growth of cambium cells of radishes are promoted; the radish size is increased, and the photosynthesis of radish leaf surfaces and the accumulation of carbohydrates are remarkably improved; the conversion of carbon-water combination is accelerated, and the synthesis and accumulation of nutrient substances are promoted, so that the target of improving the yield and nutrient substances of the radishes is achieved.

Description

technical field [0001] The invention relates to the technical field of nano-agriculture, in particular to a method for applying foliar selenium fertilizer to promote the expansion of cherry radish and the accumulation of nutrients. Background technique [0002] Cherry radish (Raphanus sativus L.var. radculus pers) is one of the most important root vegetable crops in the world. Its fresh main root contains rich nutrients, such as vitamin C, amino acids, flavonoids, etc., which can improve human immunity, prevent cell aging, and reduce the incidence of cancer in the human body. Therefore, increasing the content of nutrients in cherry radish is very beneficial to human health. At present, the main means to increase the yield and nutrients of radish is to apply exogenous fertilizers and artificially synthesized hormones. The low utilization efficiency of these substances and the residue in the fruit seriously threaten the agricultural ecological environment and people's food s...
