Auxin formula for promoting early germination of Chinese cabbage seedlings

Abstract

The invention provides an auxin formula for promoting early germination of Chinese cabbage, which is characterized by comprising corn steep liquor, brown sugar, clear water and the like, the final germination rate of Chinese cabbage seeds in clear water and plant auxin is the same, but the third day is the first day of seed germination, and the fourth day is the second day of seed germination. The germination rate of the seeds in the auxin is higher than that in clear water, which indicates that the auxin can stimulate the seeds to break dormancy and germinate in advance.

Description

Technical Field

[0001] The present invention relates to the field of agricultural technologies, and particularly to a growth hormone formulation for promoting early germination of Chinese cabbage seedlings. Background Art

[0002] Chinese cabbage, also known as pakchoi, Chinese cabbage, Brassica rapa var. glabra Regel, etc., is a variant plant of Brassica rapa L. in the Brassicaceae family. It is a biennial herbaceous plant, often with the whole plant hairless. There are many basal leaves, obovate-oblong to broadly obovate, and the upper stem leaves are oblong-ovate, oblong-lanceolate to lanceolate, with powdery frost. The flowers are bright yellow, and the petals are obovate. The silique is relatively thick and short, flattened on both sides, and the apex is round. The fruit pedicels are spreading or ascending and relatively thick. The seeds are spherical and brown. The flowering period is in May, and the fruiting period is in June.

[0003] Chinese cabbage is native to North China and is a vegetable crop widely cultivated in Asian regions, especially in China, South Korea, and Japan. In China, it is the main vegetable in winter and spring in the Northeast and North China. Chinese cabbage is relatively cold-tolerant and prefers a cool climate, suitable for growing in the cool season, and is suitable for planting in loam, sandy loam, and black loess soil that can retain fertilizer, retain water, and are rich in organic matter.

[0004] The fresh leaves and roots of Chinese cabbage can be used as medicine. The Chinese medicine name is Huangya Chinese Cabbage, which is mainly used to promote digestion, soothe the stomach, and promote urination. Chinese cabbage can be eaten raw, stir-fried, pickled with salt, or pickled with soy sauce. The outer leaves that fall off can be used as feed.

[0005] In order to shorten the planting cycle of Chinese cabbage, the problem of shortening the germination time of Chinese cabbage should be addressed first at the source. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the present invention provides a growth hormone formulation for promoting early germination of Chinese cabbage seedlings.

[0007] To achieve the above objectives, the technical solution of the present invention is realized through the following technical solutions:

[0008] A growth hormone formulation for promoting early germination of Chinese cabbage seedlings, characterized in that it includes corn steep liquor, brown sugar, and water.

[0009] Further, by weight ratio, each portion contains 25%-35% of the corn steep liquor, 5%-15% of the brown sugar, and 55%-65% of the water.

[0010] Further, by weight ratio, each portion contains 30% of the corn steep liquor, 10% of the brown sugar, and 60% of the water.

[0011] Further, the manufacturing method includes the following steps:

[0012] Step 1: Crush the immature corn kernels at the milk-ripe stage to obtain corn slurry, and mix the corn slurry with brown sugar and water to form a solution.

[0013] Step 2: Pour the mixed solution into a sealed container for fermentation, and the fermentation time is 30 - 40 days.

[0014] Step 3: Filter the fermented solution to obtain the auxin.

[0015] The present invention provides an auxin formula for promoting early germination of Chinese cabbage seedlings. The final germination rates of Chinese cabbage seeds in clear water and plant auxin are the same. However, on the 3rd day, which is the first day of seed germination, the germination rate of seeds in plant auxin is higher than that in clear water, indicating that plant auxin can stimulate seeds to break dormancy and germinate earlier. Specific Embodiments

[0016] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0017] Example 1:

[0018] By weight ratio, each portion contains 30% of the corn slurry, 10% of the brown sugar, and 60% of the water. The production method includes the following steps:

[0019] Step 1: Crush the immature corn kernels at the milk-ripe stage to obtain corn slurry, and mix the corn slurry with brown sugar and water to form a solution.

[0020] Step 2: Pour the mixed solution into a sealed container for fermentation, and the fermentation time is 30 - 40 days.

[0021] Step 3: Filter the fermented solution to obtain the auxin.

[0022] The experiment has 1 control group, 1 auxin group, and 3 replicates, with a completely randomized design. Dilute the above-obtained auxin liquid by 500 times and take out 10 ml of the auxin liquid to set as the auxin group. At the same time, set a control group, and the control group is 10 ml of mountain spring water. Both groups treat 50 Chinese cabbage seeds in the following way. First, lay 2 layers of 10 cm × 8 cm facial tissues in a petri dish, then add 10 ml of the corresponding liquid to the petri dish, and then evenly spread the Chinese cabbage seeds on the facial tissues. Then place the petri dish in a tray and seal it with plastic wrap. The experimental results are shown in the following table:

[0023] The germination rate is expressed as the average plus the standard deviation.

[0024] Test results of the germination rate of Chinese cabbage

[0025]

[0026] According to the above table, the Chinese cabbage seeds started to germinate on the 3rd day. The germination rate of the control group and the auxin group reached the peak on the 5th day and remained unchanged after the 6th day. The germination rate on the 5th day was the final germination rate.

[0027] The final germination rate of Chinese cabbage seeds in water and plant auxin is the same. However, on the 3rd day, which is the first day of seed germination, the germination rate of seeds in plant auxin is higher than that in water, indicating that plant auxin can stimulate seeds to break dormancy and germinate earlier.

[0028] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
