Description

TECHNICAL FIELD

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

[0002] Mung bean is one of traditional edible bean crops in China. Mung bean is widely planted in northwest China and other regions, and scattered planting in dry land is one of main forms of mung bean cultivation. Mung bean is relatively tolerant to poor soil, and scattered planting in family unit is often distributed in high-slope hills and poor soil plots. Cultivation area is small, and mung bean yield level is not high and unstable due to influence of adverse factors such as drought. It is of important production significance to take simple and effective technical means to improve yield and quality of mung bean.

[0003] Seed soaking before sowing is one of common methods for improving seed germination and seedling growth of crops and improving yield. At present, the yield and quality of mung bean are improved by directly using water for seed soaking. However, the yield obtained by water soaking is still low, and therefore more ways are needed to improve yield and quality of mung bean. SUMMARY

[0004] To solve the above problems, the application provides application of choline chloride and aspartic acid in improving yield and quality of crops and a method thereof.

[0005] The application of choline chloride and aspartic acid in improving yield and quality of crops is to pretreat crop seeds with a mixed solution of the choline chloride and the aspartic acid to improve yield and quality of crops.

[0006] The mass concentration ratio of the choline chloride to the aspartic acid is 1-2:1.

[0007] Preferably, the concentration of choline chloride in the mixed solution is 200 mg / L-500 mg / L, and the concentration of aspartic acid is 200 mg / L-500 mg / L.

[0008] Preferably, the pretreatment is seed soaking or seed dressing.

[0009] Preferably, when seed soaking or seed dressing, the mass-volume ratio of the mixed solution to the crop seeds is 1-2:1.

[0010] Preferably, the seed soaking or seed dressing time is 1 h-5 h.

[0011] Preferably, the crop is mung bean.

[0012] Preferably, the quality refers to grain length and protein content.

[0013] The application discloses a method for improving crop yield and quality, and the method comprises the following steps: soaking or mixing seeds of crops with a mixed solution, and then sowing the seeds after drying, so as to improve the yield and quality of the crops.

[0014] The concentration of choline chloride in the mixed solution is 200 mg / L-500 mg / L, and the concentration of aspartic acid is 200 mg / L-500 mg / L.

[0015] Preferably, the crops are mung beans.

[0016] Preferably, the quality refers to grain length and protein content.

[0017] Compared with the prior art, the application has the advantages that:

[0018] Robust root system is the basis for crop growth and high yield, but the yield improvement is affected by many factors, and the application is verified by field tests, and it is found for the first time that, compared with soaking seeds with water, soaking seeds with a mixed solution of choline chloride and aspartic acid can significantly improve the yield and quality of mung beans, and therefore the application of choline chloride and aspartic acid in improving the yield and quality of crops is proposed.

[0019] Meanwhile, it is found that 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, so that the yield and quality of mung beans can be significantly improved.

[0020] The choline chloride and aspartic acid used in the application are all low-cost reagents in the market, a large number of seeds can be soaked at one time, and the reagent cost is less than 0.5 yuan / mu. Moreover, the reagents used in the method are all environment-friendly reagents. The choline chloride has very low toxicity and is often used as a feed additive, and the aspartic acid is a non-toxic compound, so the method is safe and feasible, has no risk of human health and environmental pollution, and has good application and promotion value.

[0022] The specific embodiments of the application are described in detail below, but it should be understood that the protection scope of the application is not limited by the specific embodiments. Based on the examples in the application, all other examples obtained by those skilled in the art without creative labor are within the protection scope of the application. The experimental methods described in the embodiments of the application are all conventional methods, unless otherwise specified.

[0023] The application uses a commercially available plant growth regulator choline chloride (such as choline chloride 60% aqueous solution) and aspartic acid to configure a mixed solution, the mass ratio of choline chloride to aspartic acid is 1:1, and the concentration of the mixed solution can be selected from 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 above mixed solution is used for seed soaking or seed dressing treatment of mung bean seeds for 1-5 hours.

[0024] After drying, it can be used for normal machine seeding and manual seeding. Compared with the conventional method of using only water for seed soaking, the addition of choline chloride + aspartic acid during seed soaking can significantly improve the root growth of mung bean, and increase the yield and quality of mung bean.
