Description

Technical Field

[0001] The present invention belongs to the technical field of vegetable cultivation, and in particular to the field under classification number A01G22 / 25. More specifically, it relates to a fertilizer combination for promoting ginger bud differentiation and a fertilizing method for multi-layered ginger. Background Art

[0002] Ginger has a wide range of edible and medicinal uses. my country is the world's leading ginger producer, ranking first in both cultivated area and yield. However, ginger has a long growing period and is susceptible to environmental factors. Temperature, rainfall, pests and diseases, and other factors can significantly affect ginger yield and shape, and thus its economic value. According to market feedback, the arrangement, shape, and color of the underground rhizomes determine ginger's quality and selling price, while the number and maturity of the rhizomes are the determining factors in yield. Therefore, obtaining more ginger buds within the same growing period and ensuring their complete expansion and maturity is the key to high-yield and high-quality ginger cultivation, and is crucial for increasing production and income.

[0003] Traditional ginger bud differentiation is mostly in the form of "1-2-4-8", that is, a ginger bud undergoes three differentiations, each time differentiating into two ginger buds, and then further expands and matures. In recent years, some multi-layered Yuanbao ginger differentiated in the form of "1-3-6-12" have also appeared. The ginger shape of this kind of ginger is fuller and more compact, not only better in appearance, but also more resistant to transportation, and has higher economic value. However, this kind of multi-layered Yuanbao ginger appears occasionally during the planting process, the harvest ratio is uncontrollable, and stable production cannot be achieved. Prior art CN114988968A discloses a fertilizer composition and a fertilization method for promoting the increase in ginger production. A combination of a plurality of trace element liquid fertilizers, medium and trace element liquid fertilizers, and medium element liquid fertilizers are applied to ginger, which is beneficial to promote the differentiation and expansion of ginger buds, improve quality and increase production; but its yield increase can only reach about 18%, and the harvested ginger is mostly ordinary Yuanbao ginger, which is not sold at a high price and has a low yield rate. Summary of the Invention

[0004] In view of the defects of the prior art, the object of the present invention is to provide a fertilizer combination that can effectively promote the differentiation of ginger buds.

[0005] On the other hand, the present invention also aims to provide a method for fertilizing multi-layered Gingerbread which can improve the yield of multi-layered Gingerbread, reduce the defective rate, and obtain a better fruit shape.

[0006] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions:

[0007] A fertilizer combination for promoting ginger bud differentiation comprises two or more plant signal transduction agents.

[0008] Preferably, the plant signal transduction agents include Yu Nong Bao and Yi Da Tong.

[0009] Preferably, the dosage ratio of Yu Nong Bao and Yi Da Tong is 5g:0.5~3mL.

[0010] For example, the dosage ratio of the Yu Nong Bao and Yi Da Tong is 5g:0.5mL, 5g:1mL, 5g:1.5mL, 5g:2mL, 5g:2.5mL or 5g:3mL.

[0011] Preferably, the Yunongbao is Yunongbao FP-Pro organic water-soluble fertilizer powder produced by STET Acquisition Company;

[0012] Preferably, the Yidatong is the Yidatong aqueous solution produced by Brandt Co., Ltd. of the United States.

[0013] The present invention also provides a fertilization method for multi-layered ginger, which comprises applying the above-mentioned fertilizer combination for promoting ginger bud differentiation.

[0014] Preferably, the application includes applying the above-mentioned fertilizer combination for promoting ginger bud differentiation during the ginger sun-drying period, between the three-pronged fork stage and the six-pronged fork stage, and between the six-pronged fork stage and the twelve-pronged fork stage.

[0015] Preferably, during the ginger drying period, 5g:0.5-1.5mL of a fertilizer combination of Yu Nong Bao and Yi Da Tong is sprayed on the ginger seeds.

[0016] Further preferably, during the ginger sun-drying period, the fish and agricultural treasure is dissolved in 130 to 200 times the mass of water, and then a corresponding volume of Yidatong is added and sprayed on the ginger seeds; the ratio of the fish and agricultural treasure, Yidatong and ginger seeds is 5g: 0.5 to 1.5mL: 40 to 60kg;

[0017] More preferably, the ratio of the Yu Nong Bao, Yi Da Tong and ginger seeds is 5g:1mL:50kg.

[0018] Because seed ginger typically undergoes winter storage, it can still produce small or non-budding sprouts after sun-drying and curing. This results in a low first sprout rate, significantly impacting planting success rates and wasting ginger seeds and labor costs. This invention significantly improves the first sprout rate and the proportion of high-quality first sprouts by spraying an appropriate amount of a combination of Yu Nong Bao and Yi Da Tong fertilizers during sun-drying. These sprouts are plump, white, and bright, making them more likely to differentiate into multiple ginger buds later, meeting the prerequisites for the "1-3-6-12" differentiation method.

[0019] Preferably, the ginger seedlings are drip-irrigated or flushed with a fertilizer combination that promotes ginger bud differentiation 1 to 2 times between the time of transplanting and the three-pronged fork stage, and the dosage of the fertilizer combination that promotes ginger bud differentiation is 450 to 600 g / mu of Yunongbao and 150 to 250 mL / mu of Yidatong; further preferably, the dosage of the fertilizer combination that promotes ginger bud differentiation is 500 g / mu of Yunongbao and 200 mL / mu of Yidatong.

[0020] To encourage more ginger buds to differentiate in a "1-3-6-12" pattern and produce more expanded underground rhizomes, the present invention applies a fertilizer combination of Yunongbao and Yidatong between seedling emergence and the three-branch fork stage to induce the ginger buds to differentiate into three buds. The inventors found that ginger plants not treated with the fertilizer combination promoting ginger bud differentiation had individual buds that germinated early and exhibited strong apical dominance, which inhibited the growth and differentiation of other ginger buds. The Yunongbao and Yidatong fertilizer combination of the present invention promotes balanced nutrient distribution, inhibiting premature bud germination to a certain extent and weakening the apical dominance of early-germinating ginger buds over other ginger buds. This promotes symmetrical growth of ginger buds, ensuring that more ginger buds differentiate into three buds for the first time, and allowing the ginger to differentiate according to the "1-3-6-12" pattern.

[0021] Preferably, the ginger seedlings are drip-irrigated or flushed with a fertilizer combination for promoting ginger bud differentiation 1 to 2 times between the three-pronged fork stage and the six-pronged fork stage, and the dosage of the fertilizer combination for promoting ginger bud differentiation is 450 to 600 g / mu of Yunongbao and 150 to 250 mL / mu of Yidatong; further preferably, the dosage of the fertilizer combination for promoting ginger bud differentiation is 500 g / mu of Yunongbao and 200 mL / mu of Yidatong.

[0022] The period between the three-pronged fork stage and the six-pronged fork stage is the vigorous growth period of ginger, and vegetative growth and reproductive growth proceed simultaneously. At this time, multiple applications of the fertilizer combination for promoting ginger bud differentiation of the present invention can accelerate the growth rate of ginger, and at the same time increase the number of branches, generally with one more bud than the ginger in the same period in traditional planting; on the other hand, the fertilizer combination of the present invention not only promotes the differentiation of ginger buds, but also is beneficial to the growth and expansion of ginger buds. After applying the fertilizer combination for promoting ginger bud differentiation of the present invention, there are more bud points and the connection points between ginger buds are thicker, which effectively promotes faster and more accumulation and balanced distribution of nutrients, providing favorable conditions for the next differentiation.

[0023] Preferably, the ginger seedlings are drip-irrigated or flushed with a fertilizer combination for promoting ginger bud differentiation 1 to 2 times between the six-fork stage and the twelve-fork stage, and the dosage of the fertilizer combination for promoting ginger bud differentiation is 450 to 600 g / mu of Yunongbao and 150 to 250 mL / mu of Yidatong; further preferably, the dosage of the fertilizer combination for promoting ginger bud differentiation is 500 g / mu of Yunongbao and 200 mL / mu of Yidatong.

[0024] When ginger enters the six-pronged fork stage, it still needs to undergo the third differentiation and expansion. The degree of the third differentiation has a crucial influence on the number of mature rhizomes in the end, and determines whether the ginger shape is full and compact enough. The fertilizer combination for promoting ginger bud differentiation of the present invention is applied again between the six-pronged fork stage and the twelve-pronged fork stage, which can induce the ginger bud to undergo the third differentiation. The inventors also found that if only Yunongbao is applied, ginger is more likely to expand and grow, but it will affect the differentiation rate. Only when Yunongbao and Yidatong are applied together, the differentiation induction effect on ginger buds is better, which can ensure that more ginger buds complete the third differentiation, so that the final ginger has more than 18 mature rhizomes, and the ginger shape is full and compact. It is not only of high quality and high yield, but also more resistant to storage and easy to transport.

[0025] Preferably, the fertilizing further comprises applying one or more of rooting agents, microbial agents, pesticides, balanced macronutrient fertilizers, phosphorus fertilizers, nitrogen fertilizers, and potassium fertilizers.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The fertilizer combination for promoting ginger bud differentiation of the present invention can effectively promote the differentiation of ginger in the "1-3-6-12" pattern, obtaining multi-layered Yuanbao ginger with more than 18 mature rhizomes, significantly increasing ginger yield;

[0028] 2. The fertilizer combination for promoting ginger bud differentiation of the present invention is beneficial to the germination, differentiation and expansion of ginger buds, making the ginger grow symmetrically, with a full shape and good surface gloss;

[0029] 3. The fertilization method of the present invention can ensure that ginger undergoes sufficient differentiation and expansion at each growth stage, thereby reducing the defective rate;

[0030] 4. The fertilization method of the present invention has a high proportion of multi-layered ginger in the ginger harvested, which can reach more than 70%, and the yield per mu increases by more than 20%. In addition, the harvested multi-layered ginger is of high quality, good ginger shape, storage resistance, and good surface gloss, which is more popular with consumers and has extremely high industrial value and economic value.

[0031] 5. The fertilization method of the present invention can enable ginger to start accumulating dry matter earlier, thus avoiding yield reduction caused by excessive rain. It can be applied to different regions and climates and has wide adaptability. BRIEF DESCRIPTION OF THE DRAWINGS
