[0002] With global warming, drought has become a significant threat to crop yields. Wheat, one of the world's three major grains, is a crucial component of the human diet. In recent years, wheat production has declined due to droughts caused by climate change, posing a challenge to food security.

[0003] Currently, the drought resistance of wheat seed treatment agents is mainly achieved by adding polyacrylate to increase the drought resistance of wheat. However, this method of using polyacrylate increases the drought resistance of wheat by retaining moisture in the soil, and it cannot achieve the goal of continuous drought resistance during long periods of drought, nor can it achieve the goal of wheat frost resistance.

[0028] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0029] Unless otherwise specified, the experimental methods used in the embodiments of this specification are conventional methods. Unless otherwise specified, all experimental materials used are commercially available.

[0030] This specification provides a wheat drought-resistant seed treatment agent, which includes:

[0031] Sodium nitrophenolate, oligosaccharides, fulvic acid substances, plant hormones, cis-3-hexenol and adhesives;

[0032] The concentration of sodium nitrophenolate is 0.1-0.25%, the concentration of oligosaccharide is 0.05-0.1%, the concentration of fulvic acid is 0.1-0.2%, and the binder is a mixture of sodium alginate and potassium humate sulfonate, wherein the ratio of sodium alginate to potassium humate sulfonate is 1:2-1:5.

Specifically, sodium nitrophenolate can act as a cell revitalizer, promoting protoplasmic flow, accelerating cell division and growth, enhancing crop metabolic activity, and also relieving fertilizer antagonism, improving fertilizer nutrient absorption efficiency, and thus having a drought-resistant effect.

[0034] In the embodiments described in this specification, oligochitosan can activate the natural immunity of wheat, promote root development, and improve drought resistance.

[0038] In the embodiments of this specification, the fulvic acid substance is potassium fulvicate.

[0039] Fulvic acids are active ingredients extracted from natural humic acid. They possess small molecular structures and high biological activity, enabling soil improvement and regulating stomatal opening to reduce transpiration, thereby enhancing drought resistance. Furthermore, they can mitigate oxidative damage and improve frost resistance at low temperatures.

[0040] In the embodiments described in this specification, the potassium humate is mineral-derived potassium humate.

[0041] Potassium humate can be used as a mineral-active potassium fertilizer. It can be used as a fertilizer after seed dressing and sowing to provide nutrition for wheat, thereby improving soil and promoting growth and stress resistance.

[0042] Mineral-derived fulvic acid has a small molecular weight (hundreds to thousands), excellent water solubility, and can be directly absorbed by plants.

[0043] In the embodiments of this specification, the fulvic acid substance is used in combination with Bacillus subtilis, and the mass ratio of the fulvic acid substance to the Bacillus subtilis is 2:1-5:1.

[0044] In the embodiments described in this specification, Bacillus subtilis is stored by the applicant company, specifically Bacillus subtilis B-91.

[0045] In the embodiments described in this specification, the plant hormone is gibberellin and / or abscisic acid.

[0046] In the embodiments described in this specification, the concentration of gibberellin in the wheat drought-resistant seed treatment agent is 4000 mg / L, and / or the concentration of abscisic acid in the wheat drought-resistant seed treatment agent is 200 ppm.

[0050] In the embodiments described in this specification, the wheat seed treatment acclimatization agent is diluted at 1-3% of the seed weight, evenly coated, air-dried, and then sown.

[0051] or

[0052] The wheat seed treatment agent is diluted 500-1000 times and then sprayed on the leaves.

[0053] To verify the effect of the embodiments in this specification on the cold resistance of wheat, the embodiments in this specification are further used to verify the drought resistance.

[0054] Table 1: Physicochemical properties of the soil used in the experiment

[0055]

[0056] The experiment included two factors: seed treatment (B1 and no seed treatment B0) and irrigation frequency (no irrigation during the growth period W0, one irrigation at the jointing stage W1, and three irrigations at the jointing, heading, and grain-filling stages W3), for a total of 6 treatments with 3 replicates, arranged in a randomized block design. The plot area was 2*5=10m². 2 A 0.5-meter-wide protective row was set up around the perimeter of the residential area. To simulate drought conditions, natural rainfall before the wheat jointing stage was drained out of the area by covering it with plastic film; after the jointing stage, all areas were left to receive natural rainfall.

[0057] During the harvest period, the aboveground biomass, number of ears per mu (667 square meters), number of grains per ear, 100-grain weight, and grain yield of winter wheat were investigated. The total number of ears per mu was calculated by measuring the total number of ears in double rows of 1 meter in each plot. Two points were randomly selected in each plot, and 30 wheat plants were randomly collected from each point to measure the aboveground biomass and number of grains per ear. The entire plot was harvested and threshed to obtain the grain yield, and then the 100-grain weight was measured.

[0058] Drought Resistance Index (DI) = (BlW0)² * (B1W3) -1 *B0W3*(B0W0) -2

[0059] Wherein, B1W0, B1W3, B0W3, and B0W0 represent the grain yield of this treatment, respectively.

[0060] The effects of different treatments on the dry matter accumulation of wheat at harvest are shown in Table 2. Treatment B1W3 showed the highest aboveground dry matter accumulation of winter wheat, at 758.34 kg / mu, significantly higher than other treatments by 13.57%–80.72%. Under the same irrigation conditions, the dry matter accumulation of wheat treated with seeds was significantly higher than that of wheat not treated with seeds, with increases ranging from 23.12% to 36.48%. This indicates that seed treatment can significantly increase the dry matter accumulation of winter wheat, and this increase is proportional to the number of irrigations.

[0061] Table 2. Effects of different seed dressing and irrigation treatments on wheat dry matter accumulation, yield, and its components.

[0062]

[0063] Table 2 shows that the B1W3 and BIW1 treatments had higher winter wheat grain yields, significantly higher than other treatments, but the difference between the two treatments was not significant. Under the same irrigation conditions, the grain yields of the seed-treated treatments were significantly higher than those of the untreated treatments, with increases ranging from 12.26% to 31.91%. Different seed-treated and irrigation treatments significantly affected the number of ears per mu (a Chinese unit of area, approximately 0.067 hectares) of winter wheat. With the increase in the number of irrigations, the number of ears per mu increased significantly, with increases ranging from 21.01% to 38.35%. Under the same irrigation conditions, except for the W3 treatment, the number of ears per mu in the seed-treated treatments was significantly higher than that in the untreated treatments. This indicates that seed-treated treatments significantly increased the number of tillers and effective ears of winter wheat. When irrigated three times, there was no significant difference in the number of ears per mu between the seed-treated and untreated treatments, and under the seed-treated treatment, there was no significant difference between the treatments with one irrigation and those with three irrigations.

[0064] The number of grains per ear showed a similar trend. Both seed dressing and irrigation increased the number of grains per ear. Irrigation once significantly increased the number of grains per ear by 8.42%–12.12% compared to no irrigation. With increasing irrigation frequency, the number of grains per ear did not show a significant increasing trend. Under no irrigation conditions, there was no significant difference in the number of grains per ear between seed dressing and no seed dressing treatments. With one and three irrigations, the number of grains per ear in the seed dressing treatment was higher than that in the no-seed dressing treatment, increasing by 5.38% and 3.68%, respectively.

[0065] Different seed treatments and irrigation treatments significantly affected the thousand-grain weight of winter wheat. With the increase of irrigation frequency, the thousand-grain weight of wheat increased significantly, with an increase of 4.54% to 10.46%. Under the single irrigation and no irrigation treatments, the seed treatment and no seed treatment treatments had no significant effect on the thousand-grain weight of wheat. However, under the three irrigation treatments, the thousand-grain weight of the seed treatment treatment was significantly higher than that of the no seed treatment treatment, with an increase of 7.12%.

[0066] A comprehensive analysis of the relationship between yield and its components, and the number of seed dressing and irrigation sessions, shows that seed dressing significantly increases dry matter accumulation, number of spikes per acre, and number of grains per spike in winter wheat, thereby increasing wheat grain yield. Furthermore, seed dressing treatment achieves yield levels comparable to three irrigation sessions with only one irrigation.

[0067] To further verify the drought resistance effect, the correlation between wheat yield and its components was further studied.

[0068] Table 3 shows the correlation between wheat yield and topsoil nutrients at harvest. As can be seen from Table 3, wheat grain yield is significantly positively correlated with other indicators, with correlation coefficients of 0.854, 0.932, 0.908, and 0.763, respectively. This indicates that different treatments can significantly increase wheat grain yield by improving wheat dry matter accumulation, number of ears per mu (unit of area), number of grains per ear, and thousand-grain weight.

[0069] Table 3. Correlation between wheat yield and topsoil nutrients at harvest.

[0070]

[0071]

[0072] Further analysis of the experimental results was conducted to determine the drought resistance of wheat acclimatization agents during the growth period. Table 2 shows that the grain yields of the B1W0, B1W3, B0W3, and B0W0 treatments were 309.56 kg / mu, 404.89 kg / mu, 360.67 kg / mu, and 234.67 kg / mu, respectively. The calculated drought resistance index (DI) was 309.56. 2 / 404.89*360.67 / 234.67 / 234.67=1.55.

[0073] According to the Technical Specification for Identification and Evaluation of Drought Resistance of Wheat GB / T21127-2007, wheat treated with seed dressing agent has an extremely high drought resistance level (HR), which is the highest drought resistance level.

[0074] The comprehensive experimental results show that seed dressing treatment significantly increases dry matter accumulation, number of spikes per mu (667 square meters), and number of grains per spike in winter wheat, thereby increasing wheat grain yield, which increases with the number of irrigations. Correlation analysis among the various indicators shows a significant positive correlation between grain yield and other indicators, indicating that increasing dry matter accumulation, number of spikes per mu, number of grains per spike, and thousand-grain weight can significantly improve wheat grain yield. The drought resistance level of wheat treated with the seed dressing agent is extremely high (HR), belonging to the highest drought resistance level. It was also found that under the experimental rainfall year conditions, one irrigation under seed dressing treatment can achieve the yield level of three irrigations. In summary, the comprehensive effect of one irrigation under seed dressing conditions is the best.

[0075] In this embodiment, the seed treatment method adopted is as follows: the seed acclimatization agent is sodium nitrophenolate, oligosaccharide, fulvic acid, plant hormone, cis-3-hexenol and adhesive.

[0076] The embodiments in this specification further verify that the seed treatment acclimatization agent is sodium nitrophenolate, oligosaccharide, fulvic acid substances, plant hormones, cis-3-hexenol and adhesive, and that the seed treatment acclimatization agent is sodium nitrophenolate, oligosaccharide, fulvic acid substances, Bacillus subtilis, plant hormones, cis-3-hexenol and adhesive.

[0077] Figure 1 This diagram illustrates the effect of the wheat domestication seed treatment agent provided in the embodiments of this specification on wheat yield. Figure 1 As shown, experiments were conducted using different dosages of the seed acclimatization agent of this application, with irrigation and rain-fed (i.e., no irrigation, relying entirely on rainwater) as controls. The results showed that the seed acclimatization agent of this application can achieve drought resistance and significantly increase yield. Specifically, compared with other commercially available seed acclimatization agents, the first dosage of Seed Acclimatization Agent No. 1 increased yield by 21.37%; the second dosage increased yield by 27.20%; the third dosage increased yield by 14.39%; and the dosage of Seed Acclimatization Agent No. 2 increased yield by 44.42%. The first dosage of Seed Acclimatization Agent No. 1 was 40 g / mu, the second dosage was 80 g / mu, the third dosage was 160 g / mu, and the dosage of Seed Acclimatization Agent No. 2 was 80 g / mu. Among them, Seed dressing agent No. 1 consists of sodium nitrophenolate, oligosaccharide, fulvic acid, plant hormone, cis-3-hexenol and binder, while Seed dressing agent No. 2 consists of sodium nitrophenolate, oligosaccharide, fulvic acid, Bacillus subtilis, plant hormone, cis-3-hexenol and binder.

[0078] Meanwhile, the number of ears also increased significantly. Table 4 shows the effects of different seed treatment agents provided in the examples of this specification on the components of wheat yield.

[0079] Table 4. Effects of different seed dressing agents on wheat yield components

[0080]

[0081] The examples in this specification further investigate the effects of different seed treatment agents on the number of tillers at different growth stages of wheat. Figure 2 This diagram illustrates the effects of different seed treatment agents provided in the embodiments of this specification on the number of tillers in wheat at different growth stages. Figure 2As shown, during the seedling stage, seed treatment delayed emergence, and the basic seedling trend showed a decrease in the number of seedlings, but there was no significant difference compared to the control. During the jointing stage, treatment with seed treatment agent No. 1 significantly reduced the total number of tillers, and this decrease increased with increasing agent dosage; treatment with seed treatment agent No. 2 showed no significant difference compared to the irrigation control. The trends at maturity were basically consistent with those at the jointing stage.

[0082] The examples in this specification further examine the effects on plant height, number of ears, and ear length at different growth stages of wheat. Figure 3 This diagram illustrates the results of different seed treatment agents provided in the embodiments of this specification on wheat indicators at different growth stages. Figure 3 As shown, after treatment with the seed dressing acclimatization agent, the plant height was significantly reduced compared to CK-rain-fed and CK-irrigation. The reduction in plant height increased with increasing dosage, with the No. 1-160g / mu treatment showing a significant 7.53% reduction compared to CK-rain-fed. After treatment with the seed dressing acclimatization agent, the ear height was significantly reduced compared to CK-rain-fed and CK-irrigation. The reduction in wheat plant height increased with increasing dosage of the seed dressing acclimatization agent, with the No. 1-160g / mu treatment showing a significant 9.26% reduction compared to CK-rain-fed. After treatment with the No. 1 seed dressing acclimatization agent, the ear length increased compared to CK-rain-fed and CK-irrigation, with an average increase of 9.08% compared to CK-rain-fed.

[0083] This instruction manual also further investigated the effects of different seed treatments on wheat photosynthesis, such as... Figure 4 As shown. Figure 4 This diagram illustrates the effects of different seed treatment agents provided in the embodiments of this specification on wheat photosynthesis. Figure 4 As shown, compared with the rainwater control, the photosynthetic potential increased significantly at all stages, including the jointing-booting stage, booting-flowering stage, and flowering-milk stage.

[0084] Figure 5 This diagram illustrates the effect of different seed treatment agents provided in the embodiments of this specification on the net assimilation rate of wheat. Figure 5 As shown, during the jointing-booting stage, the net assimilation rate under the No. 1 (160 g / mu) rainfed and No. 2 (80 g / mu) rainfed treatments was not significantly different from the control (CK) rainfed and CK irrigation treatments, while the No. 1 (40 g / mu) and No. 1 (80 g / mu) rainfed treatments significantly decreased the net assimilation rate. During the booting-flowering stage, except for the No. 1 (40 g / mu) rainfed treatment, the net assimilation rate of all different seed treatments was significantly higher than the control (CK) rainfed treatment, but not significantly different from the control (CK) irrigation treatment. During the flowering-milk stage, except for the No. 1 (40 g / mu) rainfed treatment, the net assimilation rate of all different seed treatments was significantly lower than the control (CK) rainfed treatment.

[0085] It should be noted that, Figures 1-5All results are from seed treatment. In fact, the methods provided in the embodiments of this specification can also be used for spraying.

[0086] The embodiments in this specification further compare the growth characteristics at different stages. During the seedling stage, the following characteristics are predominant: slow growth, creeping growth, mainly focused on root development, wide and thick leaves, dark green leaf color, many branches, long leaves, short stems, and minimal water and nutrient consumption during the seedling stage, allowing for timely early sowing.

[0087] Winter: Excellent cold resistance, strong overwintering ability, reduced dormancy time, and increased effective tillering.

[0088] Spring: Early greening, strong uniformity, strong resistance to adverse conditions, vigorous growth, but not excessive vegetative growth. Effectively reduces the occurrence of root rot, reduces head loss, increases the number of ears per acre, consumes very little water and nutrients, and has outstanding drought resistance.

[0089] During the heading stage: A large and healthy flag leaf indicates a wider and more nutritious heading, resulting in better and larger ears, increased grain production, and higher yields and income.

[0090] Maturity stage: Matures with live stalks, naturally turns yellow, resistant to lodging, and highly resistant to hot and dry winds. Increases thousand-grain weight, produces fuller grains, saves water and fertilizer, purifies the soil, saves more than 50% of water throughout the growing season, and increases yield by about 10%.

[0091] The wheat drought-resistant seed treatment agent provided in the embodiments of this manual can achieve early drought resistance in wheat seedlings, and the drought resistance effect can last until the mid-stage and maturity of wheat, and it also has a frost resistance effect. While achieving drought and frost resistance, it can also make the grains fuller, increase the thousand-grain weight, improve the flour yield, make the ears fuller, and increase the number of grains per ear, thus achieving the effect of increasing yield.

[0092] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0093] The above description is merely an embodiment of this specification and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.
