Description

Technical Field

[0001] This invention belongs to the field of ginger cultivation technology, specifically relating to a ginger direct-seeding agent and its preparation method. Background Technology

[0002] Ginger is an important agricultural specialty crop in my country, possessing multiple uses including edible and medicinal purposes. It is also a popular export vegetable, boasting high yields and efficiency, leading to a continuously expanding cultivation area. Traditional cultivation methods involve a month-long artificial germination process in greenhouses before sowing, which is not only labor-intensive and time-consuming but also prone to problems such as seed rot, bud rot, inconsistent bud size, and decreased quality. Post-sowing growth is poor, and pests and diseases are severe. Patent application CN200410035771.0 discloses a "Ginger Seed Soaking and Direct Seeding Agent," but in practical application, it still suffers from multiple buds (multiple buds on a single ginger seed) and seed rot due to insufficient soil temperature. Furthermore, because it contains potassium permanganate, a controlled chemical, its application is limited and cannot be easily and effectively promoted in the market. Currently, no other direct seeding agent for ginger that overcomes these shortcomings is available on the market. Summary of the Invention

[0003] The first technical problem to be solved by this invention is to provide a ginger direct-seeding agent that overcomes the defects of the prior art, eliminates the need for artificial germination, protects ginger seed tubers from damage, promotes vigorous plant growth after sowing, avoids excessive budding and seed rot caused by insufficient soil temperature, and facilitates its widespread application.

[0004] The second technical problem to be solved by the present invention is to provide a method for preparing ginger direct seeding agent.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0006] A ginger direct-seeding agent comprises the following components in parts by weight: 30-50 parts potassium persulfate, 3-5 parts earthworm enzyme, 0.6-2 parts alginic acid, 0.5-2 parts fish protein, 0.6-2 parts brassinolide, 40-90 parts potassium humate, 40-90 parts potato starch, and 20-50 parts borax; water is added to bring the total weight to 10,000 parts.

[0007] Preferably, the weight percentages of each component in the ginger direct seeding agent are as follows: 40 parts potassium persulfate, 4 parts earthworm enzyme, 1.3 parts alginic acid, 1.25 parts fish protein, 1.3 parts brassinolide, 65 parts potassium humate, 65 parts potato starch, and 35 parts borax; water is added to bring the total weight percentage to 10,000 parts.

[0008] Preferably, the potassium monopersulfate, earthworm enzyme, alginic acid, fish protein, brassinolide, potassium humate, potato starch, and borax are all commercially available products. Specifically, potassium monopersulfate is a product of Jinan Tiantai Chemical Co., Ltd., earthworm enzyme is a product of Shanghai Yuanye Biotechnology Co., Ltd., alginic acid is a product of Qingdao Mingyue Algae Group Co., Ltd., fish protein is a product of Jinan Xiyue Chemical Co., Ltd., brassinolide is a product of Xinyang Mufan Biotechnology Co., Ltd., potassium humate is a product of Weifang Dayi Biotechnology Co., Ltd., and borax is a product of Jinan Zhuopu Chemical Co., Ltd.

[0009] Preferably, the potato flour is made from freshly sprouted potatoes that have been sliced, dried, and ground. Because freshly sprouted potatoes have a relatively high content of salicylic acid, this content, along with other nutrients, is used to regulate the sprouting process of ginger.

[0010] Preferably, the potato starch preparation process is as follows: select newly sprouted potatoes, wash them and slice them into pieces about 3-4 mm thick, then blanch them in a blanching tank at 70°C for 40-60 seconds, then transfer them to a dryer and dry them at 60-70°C for 2-3 hours, and finally crush them into powder with a particle size of 0.15-0.25 mm using a pulverizer.

[0011] A method for preparing a ginger direct-seeding agent includes the following steps:

[0012] a. Add potassium persulfate, earthworm enzyme, alginic acid, fish protein, brassinolide, potassium humate, potato starch and borax into the mixing tank according to the specified proportions, and add the corresponding proportions of water.

[0013] b. Turn on the stirrer and stir at 10-70 rpm until completely mixed to obtain the direct seeding agent.

[0014] Preferably, the weight parts of each component in step a are as follows: 30-50 parts potassium persulfate, 3-5 parts earthworm enzyme, 0.6-2 parts alginic acid, 0.5-2 parts fish protein, 0.6-2 parts brassinolide, 40-90 parts potassium humate, 40-90 parts potato starch, 20-50 parts borax, and water is added to make the total weight parts 10,000.

[0015] Preferably, the stirring speed in step b is 40 rpm.

[0016] Due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] The potassium persulfate compound powder of this invention, when used as an oxidizing disinfectant, has a high oxidizing potential, exceeding that of chloride, potassium permanganate, and hydrogen peroxide. It promotes the maturation of ginger rhizomes, protects them from pathogens, and facilitates rapid germination and rooting. Potassium humate contains trace elements, rare earth elements, plant growth regulators, virus inhibitors, and other nutrients, ensuring sufficient and balanced nutrient supply, thus preventing various physiological diseases in ginger caused by nutrient deficiencies. It has a particularly strong growth-regulating effect on the germination and rooting of ginger rhizomes. Fish protein has excellent stress resistance; it contains abundant fish protein amino acids and various natural active substances, effectively maintaining plant cell stability, enhancing plant physiological functions, increasing stress resistance, and making it less susceptible to pathogens and pests. It particularly improves cold resistance and significantly promotes the germination and rooting of ginger rhizomes in low-temperature soil environments. Alginic acid stimulates the activity of the body's defense enzyme system in ginger. It enhances crops' resistance to drought, cold, salinity, and other adverse conditions. It balances plant growth, promotes germination and root development, and improves the absorption and utilization of soil nutrients and water. It increases chlorophyll content, improves photosynthetic efficiency, significantly increases yield, and improves quality. Potato starch (from newly sprouted potatoes) is rich in salicylic acid, which promotes ginger germination and root development, resulting in strong roots and stems. Earthworm enzymes, rich in various amino acids, active enzymes, and active peptides, promote the growth of new roots and fine roots, resulting in whiter, thicker, stronger roots with more root hairs, enhancing the root system's ability to absorb water and nutrients. It resists continuous cropping, preventing seedling death and rot, root diseases, and soil-borne diseases; it raises soil temperature, enhancing ginger's resistance to cold and drought. It buffers soil alkalinity or acidity, regulating soil pH. It improves seedling emergence rate. Brassinolide is an excellent plant growth regulator with powerful effects. It promotes root and seedling growth, turns yellow leaves green, and has significant regulatory and repairing effects on various symptoms caused by root rot, yellowing leaves, weakness, and diseases. Borax regulates the transport system of ginger, increasing its absorption of nutrients.

[0018] The direct-seeding agent obtained by combining the above components can not only eliminate the inhibitory factors of ginger germination and rooting, supplement nutrition to induce and promote the germination and rooting of ginger seeds, prevent the harm of soil-borne diseases, avoid the occurrence of seed rot due to insufficient soil temperature and excessive buds, but also improve the growth vigor of ginger and promote yield and quality.

[0033] Experimental Example 1

[0034] The direct-seeding agent obtained in Example 3 was compared with the direct-seeding agent disclosed in the background art (the direct-seeding agent prepared according to the method of patent application number CN200410035771.0) to treat ginger seeds simultaneously, and a comparative experiment was conducted:

[0035] The ginger variety used was Shannong No. 1. The experimental area was 660 square meters in each region. Before sowing, ginger seeds were taken from the storage cellar, broken into pieces, and sun-dried for at least 4 hours until the cut surfaces were dry and the skin turned white. Then, they were soaked for 1 hour each in the direct-seeding agent prepared in Example 3 and the control direct-seeding agent, respectively. They were then directly sown on May 5, 2023 (soil temperature at a depth of 5 cm in the cultivation area was 12℃). The same management methods were used during the growth process. Samples were taken and observed simultaneously during the growth period. The experimental data obtained from sampling at different times are as follows:

[0036] (1) Germination experiment: Sampling was taken at 32 and 43 days to investigate the seedling emergence rate, seed rot rate, and multiple bud rate. The results are shown in the figure. Figure 1 And Table 1:

[0037] Table 1 Comparison of germination rate, seed rot rate, and multiple bud rate

[0038]

[0039] As shown in Table 1, the direct seeding agent in Example 3 has the characteristics of promoting rapid germination, uniform emergence, and strong growth of ginger shoots, without the occurrence of multiple shoots or seed rot, and has strong disease resistance and stress resistance, ultimately improving the yield and quality of ginger.

[0040] (2) Root growth: Root samples were taken from both the present invention and the control group at emergence and 15 days after emergence for comparison. The results are shown in the table below. Figure 2 And Table 2:

[0043] As can be seen from the experimental results in Table 2, the direct seeding agent used in Example 3 had a more significant effect on promoting root growth.

[0044] (3) Disease resistance experiment: The incidence of root rot and stem rot during the growing season was recorded. Due to the flood disaster in the summer of 2023, the overall disease incidence of the plants after the flood was also recorded. The results are shown in […]. Figure 3 And Table 3:

[0045] Table 3 Comparison of disease resistance

[0046] Root rot (%) Stem rot incidence (%) Incidence rate after flooding (%) Example 3: Direct Seeding Agent 0 4 30 Comparison of live broadcast agents 2 8 50

[0047] As can be seen from the experimental results in Table 3, the direct seeding agent in Example 3 has a significant enhancing effect on the disease resistance of ginger.

[0048] (4) Stress resistance experiment: The condition of dried ginger leaves (leaf drying caused by hot and dry wind) before and after the greenhouse was removed was statistically analyzed. The results are shown in the figure. Figure 4 And Table 4:

[0050] Dry leaf rate (%) before greenhouse removal Dry leaf rate (%) after greenhouse removal Example 3: Direct Seeding Agent 0 0 Comparison of live broadcast agents 0 6

[0051] As can be seen from the experimental results in Table 4, the direct seeding agent in Example 3 has a significant enhancing effect on the stress resistance of ginger.

[0052] (5) Plant height and stem diameter: Samples were taken on June 28, July 10, August 15, and September 15, and plant height and stem diameter were compared. The results are shown in the table below. Figure 5 And Table 5:

[0053] Table 5 Comparison of plant height and stem diameter at different growth stages

[0054]

[0055] As can be seen from the experimental results in Table 5, the ginger plants treated with the direct seeding agent of Example 3 showed more vigorous growth.

[0056] (6) Number of branches: Samples were taken on June 28, July 10, August 15, and September 15, and the number of branches was compared. The results are shown in [the table below]. Figure 6 And Table 6:
