Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural planting technology, in particular to a method for improving the yield and quality of selenium-rich Tetradium oblongum. BACKGROUND

[0002] Tetradium oblongum, a precious plant from the Rutaceae family, has attracted much attention with its unique charm. As a deciduous small tree, it has a moderate height and its branches and leaves exude elegance and vitality. The leaf axis and flower stalk of its current-year branches and new leaves are initially sparsely covered with fine soft hair, and then gradually become hairless, showing a transformation of growth. The small leaves are long and needle-shaped, with a long and sharp tip, and turn dark brown after drying. The oil dots are slightly convex, and there are 4-6 lateral veins on each side. These details all contribute to the unique morphological beauty of Tetradium oblongum.

[0003] What is even more amazing is its flowers and fruits. On the umbel-shaped cyme, many flowers bloom in competition, with long oval petals and sparkling oil dots, emitting a fascinating fragrance. The fruits are round and spherical, with many oil dots, turning brown after drying. The seeds are hidden inside, with smooth seed coat and deep green cotyledons, full of life energy. The overlapping of flowering and fruiting periods makes Tetradium oblongum show different appearances in different seasons.

[0004] The composition of Tetradium oblongum is also rich and colorful. According to the quality detection report of Guangxi Analysis and Test Research Center, the plant is rich in protein, vitamins B2, PP, C and E, and carotenoids, among other nutrients beneficial to the human body. These vitamins play an indispensable physiological and biochemical function in the human body, such as constituting the main component of coenzyme or hydrogenase, maintaining the normal function of teeth, bones, blood vessels and muscles, promoting cell respiration, maintaining skin and nerve health, and delaying aging, etc. In addition, Tetradium oblongum also contains 18 kinds of amino acids and a high content of volatile oil, which adds more health value to it.

[0005] However, despite the many advantages of Tetradium oblongum, it still faces a pressing problem: how to improve its yield and overall quality. This is not only a challenge for Tetradium oblongum 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 Tetradium oblongum, so that it can better serve human health and life.

[0006] Meanwhile, the four nine liu xiang is also developed with the effect of selenium enrichment, which undoubtedly adds more market prospects and application value. With the continuous improvement of people's health consciousness, the demand for natural, healthy and nutritious food is increasing. Therefore, the four nine liu xiang as a plant with a variety of nutrients has broad development prospects. We have reason to believe that in the near future, the four nine liu xiang will become the health choice of more people. SUMMARY

[0007] The purpose of the present application is to provide a method for improving the yield and quality of selenium-enriched four nine liu xiang, which can improve the yield and quality of selenium-enriched four nine liu xiang, thereby improving the economic benefits of selenium-enriched four nine liu xiang.

[0063] Guangxi now generally plants Elaeocarpus sylvestris, but the Elaeocarpus sylvestris has a lot of fallen leaves, and the applicant collects the Elaeocarpus sylvestris to conduct some root promoting experiments.

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

[0065] The seedling substrate of Comparative Example 2 is: sand, garden soil, self-made substrate according to the volume ratio 1:2:1, and the self-made substrate is specifically: cottonseed hulls are sprayed to a water content of 10%, and the extract solution obtained by crushing and water extracting leaves of Bauhinia championii for 10 hours is mixed with the cottonseed hulls at 10g of the extract solution per 100g of the cottonseed hulls, stirred, and stacked for fermentation for 3 days.

[0066] The seedling substrate of Comparative Example 3 is: sand, garden soil, self-made substrate according to the volume ratio 1:2:2, and the self-made substrate is specifically: cottonseed hulls are sprayed to a water content of 10%, and the extract solution obtained by crushing and water extracting leaves of Bauhinia championii for 10 hours is mixed with the cottonseed hulls at 10g of the extract solution per 100g of the cottonseed hulls, stirred, and stacked for fermentation for 3 days.

[0067] The seedling substrate of Comparative Example 4 is: sand, garden soil, self-made substrate according to the volume ratio 1:2:3, and the self-made substrate is specifically: cottonseed hulls are sprayed to a water content of 10%, and the extract solution obtained by crushing and water extracting leaves of Bauhinia championii for 10 hours is mixed with the cottonseed hulls at 10g of the extract solution per 100g of the cottonseed hulls, stirred, and stacked for fermentation for 3 days.

[0068] The seedling substrate of Comparative Example 5 is: sand, garden soil, self-made substrate according to the volume ratio 1:2:1, and the self-made substrate is specifically: cottonseed hulls are sprayed to a water content of 10%, and stacked for fermentation for 3 days.

[0069] After the seedling substrates of the above Comparative Examples 1, 2, 3, 4, and 5 are prepared, 10 seedling containers are filled with each of the seedling substrates, and 3 repetitions are set. Then, 150 seedling cups are used for cuttage and seedling of Bauhinia championii, and conventional management is performed in a seedling shed. After the seedling of Bauhinia championii cultured in the 5 different seedling substrates for 60 days, 1 plant in each of 3 repetitions of 5 groups is randomly selected for stem diameter, underground dry matter weight, and other index determination, and the average value is taken. See Table 1 for details.

[0070] Table 1

[0071]

[0072] From Table 1, it can be seen that the addition of the self-made substrate with special treatment is beneficial to rooting of the cuttage seedlings. From Comparative Example 4, it can be seen that the addition of a large amount of self-made substrate in the whole seedling substrate is not conducive to rooting, and the rooting effect is comparable to that of Comparative Example 5 without the addition of Bauhinia championii extract solution and fermented cottonseed hulls.

[0073] The compound formula of Comparative Example 3 is the most conducive to the growth of Bauhinia championii.

[0074] From the stem diameter, it can be seen that the stem diameter of Bauhinia championii in Comparative Examples 2 and 3 is at least 0.5mm thicker than that in Comparative Examples 1, 4, and 5. From the stem diameter data, it can be seen that there is a significant difference between Comparative Examples 2 and 3 and Comparative Examples 1, 4, and 5.

[0075] From the underground part of dry matter quality, the comparison of Comparative Examples 2 and 3 with Comparative Examples 1, 4 and 5, the underground part of dry matter quality of Comparative Example 2 is the most, at least 0.27 (g / plant) higher than Comparative Examples 1, 4 and 5. From the data of the aboveground part of dry matter quality, Comparative Examples 2 and 3 are significantly different from Comparative Examples 1, 4 and 5.

[0076] It can be seen that the proportion of each raw material of the seedling substrate is very important. The seedling substrate of sand, garden soil and self-made substrate in a volume ratio of 1:2:1-2 has the best root-promoting effect on Tetradium cumingii.
