Description

Technical Field

[0001] The invention relates to the technical field of agricultural planting, and in particular to a method for improving the yield and quality of selenium-rich osmanthus fragrans Background Art

[0002] Osmanthus fragrans, a precious plant from the Rutaceae family, has attracted much attention with its unique charm. As a deciduous small tree, it is of moderate height, and its branches and leaves reveal a kind of elegance and vitality. The rachis and pedicels of its current year's branches and new leaves are initially sparsely pubescent, and then gradually become hairless, showing a kind of growth metamorphosis. The leaflets are narrow and lanceolate, with a long and gradually pointed top. After drying, they are dark brown and black, with slightly convex oil spots and faint lateral veins, 4-6 on each side. These details constitute the unique morphological beauty of Osmanthus fragrans.

[0003] What is even more amazing is its flowers and fruits. On the corymb-shaped cyme, many flowers bloom in competition. The flowers are white, the petals are oblong, and the oil spots are sparkling, exuding a charming fragrance. The fruit is spherical, light red, with many oil spots, and turns brown after drying. The seeds are hidden inside, the seed coat is smooth, and the cotyledons are dark green, full of vitality. The flowering period and fruiting period are staggered, so that the four-number nine-lixiang can show different styles in different seasons.

[0004] The ingredients of osmanthus fragrans are even more colorful. According to the quality inspection report of Guangxi Analysis and Testing Research Center, the plant is rich in protein, vitamin B2, vitamin PP, vitamin C and vitamin E, carotenoids and other nutrients that are beneficial to the human body. These vitamins play an indispensable physiological and biochemical function in the human body, such as constituting the main components of coenzymes or hydrogenases, maintaining the normal functions of teeth, bones, blood vessels and muscles, promoting cell respiration, maintaining skin and nerve health, and delaying aging. In addition, osmanthus fragrans also contains 18 kinds of amino acids and high volatile oil, which add more health value to it.

[0005] However, despite the many advantages of Osmanthus fragrans, it still faces an urgent problem: how to improve its yield and overall quality. This is not only a challenge for Osmanthus fragrans itself, but also a test for agricultural researchers. In the future, we need to use more scientific planting techniques and management methods to tap the potential of Osmanthus fragrans so that it can better serve human health and life.

[0006] At the same time, the effect of enriching selenium in Osmanthus fragrans has been developed, which undoubtedly adds more market prospects and application value to it. As people's health awareness continues to improve, the demand for natural, healthy and nutritious food is also growing. Therefore, as a plant that combines multiple nutrients, Osmanthus fragrans has broad development prospects. We have reason to believe that in the near future, Osmanthus fragrans will become a healthy choice for more people. Summary of the invention

[0061] The technical solution of this application can effectively improve the yield and quality of selenium-rich four-number osmanthus, and the applicant has conducted the following experiments:

[0062] Experiment 1: The applicant's previous research revealed that the planting of Osmanthus fragrans requires seedling cultivation, and the survival rate of seedlings after seedling cultivation is closely related to the seedlings. Generally, the survival rate of seedling cultivation can be effectively improved by developing a well-developed root system and strengthening the seedlings after seedling cultivation.

[0063] Bauhinia is now widely planted in Guangxi, but many of its leaves fall off. The applicant collected Bauhinia to conduct some root promotion experiments.

[0064] Comparative Example 1: The seedling soil is: planting soil humus soil peat synthetic peat soil improved soil produced by Yunnan Yingtianqing Agricultural Technology Co., Ltd.

[0065] Comparative Example 2: The seedling medium is: sand, garden soil, and homemade medium in a volume ratio of 1:2:1. The homemade medium is specifically made by spraying cottonseed hulls with a moisture content of 10%. The extract of Bauhinia hornii leaves after crushing and water extraction for 10 hours is added with 10g of Bauhinia horn extract for every 100g of cottonseed hulls. The mixture is stirred and piled up for fermentation for 3 days.

[0066] Comparative Example 3: The seedling medium is: sand, garden soil, and homemade medium in a volume ratio of 1:2:2. The homemade medium is specifically made by spraying cottonseed hulls with a moisture content of 10%. The extract of Bauhinia hordei leaves after water extraction for 10 hours is added with 10g of Bauhinia horde extract for every 100g of cottonseed hulls. The mixture is stirred and piled up for fermentation for 3 days.

[0067] Comparative Example 4: The seedling medium is: sand, garden soil, and homemade medium in a volume ratio of 1:2:3. The homemade medium is specifically made by spraying cottonseed hulls with a moisture content of 10%. The extract of Bauhinia hordei leaves after crushing and water extraction for 10 hours is added with 10g of Bauhinia horde extract for every 100g of cottonseed hulls. The mixture is stirred and piled up for fermentation for 3 days.

[0068] Comparative Example 5: Seedling culture medium: sand, garden soil, homemade medium in a volume ratio of 1:2:1. The homemade medium is specifically made by spraying cotton seed hulls with a moisture content of 10%, and then building a pile and fermenting for 3 days.

[0069] After the seedling substrates of the above comparative examples 1, 2, 3, 4, and 5 were prepared, each group was packed in 10 seedling containers, and 3 replicates were set. Then, the four-number nine-lixiang seedlings were cut and grown in 150 seedling cups, and conventional management was carried out in the seedling shed. After 60 days of seedling cultivation of the four-number nine-lixiang seedlings cultured with the five different formulations of seedling substrates, one of the three replicates of the five groups was randomly selected to measure the index of the stem thickness and underground dry matter mass of the four-number nine-lixiang seedling, and the average value was taken. See Table 1 for details.

[0070] Table 1

[0071]

[0072] From Table 1, adding the specially treated homemade matrix is ​​beneficial to the rooting of cuttings. From Comparative Example 4, the addition of the homemade matrix in the entire seedling matrix accounts for a large proportion, but the rooting effect is not good, which is equivalent to Comparative Example 5 in which no Bauhinia extract fermented cottonseed shell is added.

[0073] The compound formula of comparative example 3 is most conducive to the growth of Osmanthus fragrans.

[0074] From the perspective of stem thickness, the comparison of the stem thickness of Comparative Examples 2 and 3 with that of Comparative Examples 1, 4, and 5 shows that the stem thickness of the four-number nine-lixiang is at least 0.5 mm thicker. From the perspective of stem thickness data, the difference between Comparative Examples 2 and 3 and Comparative Examples 1, 4, and 5 is significant.

[0075] From the perspective of underground dry matter mass, the comparison between Comparative Examples 2 and 3 and Comparative Examples 1, 4, and 5 shows that the underground dry matter mass of the four-numbered osmanthus in Comparative Example 2 is the highest, at least 0.27 (g / plant) higher than that of Comparative Examples 1, 4, and 5. From the perspective of the aboveground dry matter mass, there are significant differences between Comparative Examples 2 and 3 and Comparative Examples 1, 4, and 5.

[0076] It can be seen that the proportion of each raw material in the seedling matrix is ​​very particular. The effect of promoting the rooting of Osmanthus fragrans is best when the seedlings are grown in a seedling matrix with sand, garden soil and homemade matrix in a volume ratio of 1:2:1-2.

[0077] Experiment 2: The applicant conducted further research on the yield and quality of Osmanthus fragrans from the perspective of fertilization, and conducted the following experiments.
