Description

Technical Field

[0001] The invention belongs to the technical field of crop cultivation, and particularly relates to application of choline chloride and aspartic acid in improving crop yield and quality and a method thereof. Background Art

[0002] Mung bean is one of the traditional edible legume crops in my country. Mung bean cultivation is widely distributed in the northwest and other regions of my country. Dispersed planting in dry land is one of the main forms of mung bean cultivation. Mung bean is relatively resistant to barrenness. Dispersed planting in family units is often distributed on high slopes and hills and poor soil plots. The cultivation area is small. Affected by adverse factors such as drought, the yield of mung bean is not high and unstable. It is of great production significance to adopt simple and effective technical means to improve the yield and quality of mung beans.

[0003] Soaking seeds before sowing is one of the common methods to improve crop seed germination and seedling growth and increase yield. At present, the yield and quality of mung beans are improved by directly soaking seeds in clean water, but the yield obtained by soaking seeds in clean water is still low, so more methods are needed to improve the yield and quality of mung beans. Summary of the invention

[0004] In order to solve the above problems, the present invention provides the application of choline chloride and aspartic acid in improving crop yield and quality and a method thereof.

[0005] Application of choline chloride and aspartic acid in improving crop yield and quality, by pretreating crop seeds with a mixed solution of the choline chloride and the aspartic acid, so as to improve crop yield and quality; The mass concentration ratio of the choline chloride to the aspartic acid is 1-2:1.

[0006] Preferably, the concentration of choline chloride in the mixed solution is 200 mg / L to 500 mg / L, and the concentration of aspartic acid is 200 mg / L to 500 mg / L.

[0007] Preferably, the pretreatment is seed soaking or seed dressing.

[0008] Preferably, when soaking or mixing seeds, the mass volume ratio of the mixed liquid to the crop seeds is 1-2:1.

[0009] Preferably, the time for soaking or mixing the seeds is 1 hour to 5 hours.

[0010] Preferably, the crop is mung bean.

[0011] Preferably, the quality refers to kernel length and protein content.

[0012] A method for improving crop yield and quality, comprising soaking or mixing crop seeds with the mixed liquid, and sowing the seeds after drying, thereby improving crop yield and quality; The concentration of choline chloride in the mixed solution is 200 mg / L to 500 mg / L, and the concentration of aspartic acid is 200 mg / L to 500 mg / L.

[0013] Preferably, the crop is mung bean.

[0014] Preferably, the quality refers to kernel length and protein content.

[0015] Compared with the prior art, the present invention is beneficial in that: A robust and developed root system is the basis for crop growth and high yield, but the increase in yield is affected by many factors. The present invention has been verified through field trials and has found for the first time in mung beans that, compared with soaking seeds in clear water, soaking seeds in a mixed solution of choline chloride and aspartic acid can significantly improve the yield and quality of mung beans. Therefore, the application of choline chloride and aspartic acid in improving crop yield and quality is proposed.

[0016] At the same time, the present invention finds that when the concentration of choline chloride is 200 mg / L to 500 mg / L and the concentration of aspartic acid is 200 mg / L to 500 mg / L, the yield and quality of mung beans can be significantly improved.

[0017] The choline chloride and aspartic acid used in the present invention are both commercially available low-priced reagents, and more seeds can be soaked at one time, and the reagent cost is less than 0.5 yuan / mu. In addition, the reagents used in the method are all environmentally friendly reagents. Among them, choline chloride has extremely low toxicity and is often used as a feed additive, and aspartic acid is a non-toxic compound. Therefore, the method is safe and feasible, has no risk of human health and environmental pollution, and has good application and promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention. The experimental methods described in the embodiments of the present invention are conventional methods unless otherwise specified.

[0020] The present invention uses a commercially available plant growth regulator choline chloride (such as 60% choline chloride aqueous solution) and aspartic acid to form a mixed solution, the mass ratio of choline chloride to aspartic acid is set to 1:1, and the concentration range of the mixed solution can be selected to be 400-1000 mg / L, that is, the concentration of choline chloride is 200 mg / L-500 mg / L, and the concentration of aspartic acid is 200 mg / L-500 mg / L. The mixed solution is used to soak or dress mung bean seeds for 1 hour to 5 hours.

[0021] After drying, it can be used for normal machine sowing and manual sowing. Compared with the conventional method of soaking seeds with only water, adding choline chloride + aspartic acid during the soaking process can significantly improve the growth of mung bean roots and increase the yield and quality of mung beans.

[0022] Example 1 Effects of choline chloride + aspartic acid combined seed soaking on the root growth of mung bean like Figure 1 As shown in Table 1, compared with the traditional water soaking method, the use of choline chloride + aspartic acid compound (choline chloride 200 mg / L, aspartic acid compound 200 mg / L) for seed soaking can effectively promote the growth of mung bean seedling roots, and the root length, root weight and root surface area are significantly increased.

[0023] "*" indicates significant difference among treatments (p < 0.05).

[0024] Example 2 Effects of choline chloride + aspartic acid combined seed soaking on mung bean yield and quality As shown in Table 2 and Table 3, compared with the traditional water soaking method, soaking with choline chloride + aspartic acid (choline chloride 200 mg / L, aspartic acid 200 mg / L) can significantly improve the yield and quality of mung beans. In terms of yield, it is manifested in an increase in 100-grain weight and an increase in yield per unit area, with an increase of 7.1%. In terms of quality, it is manifested in an increase in grain length and an increase in protein content.
