Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of plant growth regulators, and relates to an agricultural composition containing hemipterins and sodium complex nitrophenol. BACKGROUND

[0002] Hemipterin is a medical intermediate with protective effect on myocardial ischemia. In recent years, it has been found that hemipterin is an effective plant growth regulator and protective agent, which can promote root development, enhance crop stress resistance and increase yield. Hemipterin mainly acts on the cell division and growth process of plants, promotes the synthesis and accumulation of protein, nucleic acid and alkaloids in plants, and also affects the hormone balance in plants to improve the adaptability of plants to the environment. Hemipterin can be applied to fruit trees to promote branching, rapid flower bud differentiation, stimulate fruit enlargement, promote fruit cell division, increase sugar content and improve fruit quality and taste.

[0003] Sodium complex nitrophenol, also known as sodium complex nitrophenol, is composed of sodium p-nitrophenol, sodium o-nitrophenol and sodium 5-nitroguaiacol. It is a strong cell activator that can rapidly penetrate into plants after contact, promote protoplasm flow in cells and improve cell vitality. As a plant growth regulator, sodium complex nitrophenol can accelerate plant growth speed and has strong promoting effect on the vegetative growth and reproductive growth of plants. It can be widely applied to promote plant growth and development, break dormancy, promote flowering, promote germination, prevent flower and fruit drop, improve product quality, and improve the stress resistance of crops such as disease resistance, insect resistance, drought resistance, waterlogging resistance, cold resistance, salt and alkali resistance, and lodging resistance. Sodium complex nitrophenol is widely used in food crops, economic crops, vegetables, melons and fruits, fruit trees, oil crops and flowers, etc., and has the advantages of high efficiency, low toxicity, no residue, wide application range, no side effects, wide use concentration range, etc.

[0004] Different plant growth regulators have different mechanisms of action. When a single agent is used alone, the yield is often improved, but the quality of the crops is affected, which cannot meet the requirements of improving the quality. Therefore, two or more plant growth regulators are mixed for use. The mixed use can make up for each other's shortcomings and overcome the disadvantages of single use. Since hemipterin and sodium complex nitrophenol have different action directions, there is no report on the use of hemipterin and sodium complex nitrophenol to regulate crop growth in crop production practice. Therefore, it is of great significance to develop a complex plant growth regulator containing hemipterin and sodium complex nitrophenol as effective components, which can promote the growth and development of crops and improve the yield and quality of crops. SUMMARY

[0005] In order to develop an agricultural composition with semileaf and sodium nitrophenolate as effective components to promote the growth and development of crops and improve the yield and quality of crops, the present application provides an agricultural composition containing semileaf and sodium nitrophenolate. The effective component mass ratio of semileaf and sodium nitrophenolate in the agricultural composition is 40-90:1-3.5. Within the ratio range provided by the present application, the agricultural composition has better promotion on the yield and quality of cucumbers, and the promotion of the yield of cucumbers by the agricultural composition provided by the present application also has a synergistic effect.

[0006] In order to achieve the technical purpose of the present application, in one aspect, the present application provides an agricultural composition, the effective components of which consist of semileaf and sodium nitrophenolate. The effective component mass ratio of semileaf and sodium nitrophenolate in the agricultural composition is 40-90:1-3.5; preferably, the effective component mass ratio of semileaf and sodium nitrophenolate in the agricultural composition is 60-80:1.5-2.5; further preferably, the effective component mass ratio of semileaf and sodium nitrophenolate in the agricultural composition is 70:2.

[0007] It is easy for those skilled in the art to know that, in order to fully exert the efficacy of the active components of plant growth regulators (pesticides), they can be prepared into formulations for convenient application according to the needs. The agricultural composition is processed into an agriculturally acceptable formulation, and the formulation contains an auxiliary agent for assisting the semileaf and sodium nitrophenolate to regulate the growth of crops. The agricultural composition can be formulated into water agent, soluble liquid agent, water dispersible granule, wettable powder, dispersible oil suspension agent, suspension agent, microemulsion, granule, and microcapsule with certain slow-release effect, etc. When formulating the above different formulations, in addition to the need to use the selected plant growth regulating active components, those skilled in the art also need to select various auxiliary agents, and different formulation auxiliary components (auxiliary agents) can be selected according to the needs. The auxiliary components can be one or more of dispersing medium, dispersant, emulsifier, wetting agent, thickening agent, antifoaming agent, antifreezing agent, disintegrating agent, binding agent, filler, carrier, etc.

[0008] In another aspect, the present application claims the use of the above-mentioned agricultural composition in improving the quality of cucumbers, which includes improving the length of cucumbers, the weight of single cucumbers, and the content of vitamin C.

[0009] Further, after the agricultural composition of the present application is applied to cucumbers, it is found that the cucumber length, single fruit weight and vitamin C content are all improved when the effective components of semileaf and sodium nitrophenolate are compounded at a mass ratio of 40-90:1-3.5, the cucumber length is increased by 20.7-28.5%, the single fruit weight is increased by 21.7-27.8%, and the vitamin C content is increased by up to 4.8%. This shows that the agricultural composition of the present application can improve the quality of cucumbers, and the effect of improving the quality of cucumbers is optimal when the mass ratio of the effective components of semileaf and sodium nitrophenolate is 70:2.

[0010] In addition, the present application claims the use of the above-mentioned agricultural composition in increasing crop yield, and the crop is cucumber.

[0011] Further, the agricultural composition of the present application has a synergistic effect when applied to cucumbers within the range provided in the present application. The effective components of semileaf and sodium nitrophenolate have a yield-increasing effect on cucumbers when compounded at a ratio of 40-90:1-3.5, the yield-increasing rate of the agricultural composition on cucumbers is 24.35-41.53%, and the difference between the actual yield-increasing rate and the theoretical yield-increasing rate is greater than 10% within the ratio range, showing a synergistic effect; when the ratio of the effective components of semileaf and sodium nitrophenolate is 60-80:1.5-2.5, the yield-increasing effect of the agricultural composition on cucumbers is optimal, the yield-increasing rate is about 40%, and the difference between the actual yield-increasing rate and the theoretical yield-increasing rate is greater than 15%, showing a better synergistic effect; when the ratio of the effective components of semileaf and sodium nitrophenolate is 70:2, the synergistic effect is best, and the difference between the actual yield-increasing rate and the theoretical yield-increasing rate is 17.27%.

[0012] Regarding the use object of the agricultural composition containing semileaf and sodium nitrophenolate, it is a crop fruit that has a demand for promoting growth or improving quality, and further preferably, the crop fruit is the fruit of cucumbers. Based on the inspiration or ideas of the technical solutions of the present application, the use object of the agricultural composition containing semileaf and sodium nitrophenolate can be further expanded to melons, fruits and vegetables.

[0013] Compared with the prior art, the technical solutions provided by the present application have at least the following beneficial effects or advantages:

[0014] The agricultural composition containing hemiphen and sodium nitrophenolate of the present application has the effect of improving the quality of cucumbers. After hemiphen and sodium nitrophenolate are compounded according to the effective component mass ratio of 40-90:1-3.5, the cucumber length, single fruit weight and vitamin C content of cucumbers are all improved well, the cucumber length is increased by 20.7-28.5%, the single fruit weight of cucumbers is increased by 21.7-27.8%, and the vitamin C content can be increased by 4.8% at most. It is shown that the application of the agricultural composition of the present application can improve the quality of cucumbers, and the effect of improving the quality of cucumbers is optimal when the effective component mass ratio of hemiphen and sodium nitrophenolate is 70:2. When the compounding ratio of hemiphen and sodium nitrophenolate changes, the effect of improving the quality of cucumbers also changes, and the application of hemiphen or sodium nitrophenolate alone also has a promoting effect on the improvement of the quality of cucumbers, but the promoting effect is poorer than that of the agricultural composition compounded according to the present application, which shows that although hemiphen and sodium nitrophenolate are both plant growth regulators, the effects and pathways they play or regulate are different, and the two can play a complementary effect well when compounded; when the compounding ratio exceeds the range provided in the present application, the effect of the agricultural composition on improving the quality of cucumbers becomes poor; and when sodium nitrophenolate is replaced by sodium α-naphthaleneacetate, the effect of the agricultural composition on improving the quality of cucumbers is reduced.

[0015] The agricultural composition containing hemiphen and sodium nitrophenolate of the present application has the effect of increasing the yield of cucumbers, and also has a synergistic effect within the compounding ratio range provided in the present application. The effective components of hemiphen and sodium nitrophenolate have the effect of increasing the yield of cucumbers when compounded within the compounding ratio range of 40-90:1-3.5, the yield increase rate of the agricultural composition on cucumbers is 24.35-41.53%, and the difference between the actual yield increase rate and the theoretical yield increase rate is greater than 10% within the compounding ratio range, which shows a synergistic effect; when the effective components of hemiphen and sodium nitrophenolate are compounded within the compounding ratio range of 60-80:1.5-2.5, the yield increase effect of the agricultural composition on cucumbers is optimal, the yield increase rate is about 40%, and the difference between the actual yield increase rate and the theoretical yield increase rate is greater than 15%, which shows a better synergistic effect; when the effective components of hemiphen and sodium nitrophenolate are compounded at the ratio of 70:2, the synergistic effect is best, and the difference between the actual yield increase rate and the theoretical yield increase rate is 17.27%. When the compounding ratio exceeds the range provided in the present application or the components of the agricultural composition of the present application are changed, the yield increase rate on cucumbers shows an additive effect, which is poorer than that of the agricultural composition of the present application.

[0016] In the following, the technical solutions of the present application will be described in conjunction with examples, but the present application is not limited to the following examples. The experimental methods and detection methods described in each example are all conventional methods unless otherwise specified; and the reagents and materials described are all commercially available unless otherwise specified.

[0018] Sodium nitrophenolate was purchased from Hubei Hengjingrui Chemical Co., Ltd., with a purity of 98%.

[0019] Sodium α-naphthaleneacetate was purchased from Hubei Daoyacheemical Co., Ltd., with a purity of 99%.

[0020] Example 1

[0021] This example provides a field test of the effect of the agricultural composition containing semileaf and sodium nitrophenolate on cucumber.

[0022] Semileaf and sodium nitrophenolate were respectively prepared into solutions, and after mixing the two solutions, leaf surface spraying treatment was carried out at the initial flowering stage and the fruiting stage of cucumber using a backpack electric sprayer, and the spraying amount was 10 L per mu. After spraying the agricultural composition, the management was the same as that in the field.

[0023] The test site was a cucumber planting greenhouse in Wucun Town, Yaodu District, Linfen City, Shanxi Province, and the tested cucumber variety was Zhongnong No. 12. The cucumber field was well managed in terms of fertilizer and water, and the plot test method was adopted. The test plot area was 35 m 2 , randomly arranged in groups, and repeated three times. Sowing was carried out in mid-March, and planting was carried out in late April, with a sowing distance of 35 cm x 50 cm.

[0024] The test involved 24 treatments, respectively: test 1~7: only semileaf was applied; test 8~14: only sodium nitrophenolate was applied; test 15: only sodium α-naphthaleneacetate was applied; test 16: the effective ingredient mass ratio of semileaf and sodium nitrophenolate was 40:3.5; test 17: the effective ingredient mass ratio of semileaf and sodium nitrophenolate was 50:3; test 18: the effective ingredient mass ratio of semileaf and sodium nitrophenolate was 60:2.5; test 19: the effective ingredient mass ratio of semileaf and sodium nitrophenolate was 70:2; test 20: the effective ingredient mass ratio of semileaf and sodium nitrophenolate was 80:1.5; test 21: the effective ingredient mass ratio of semileaf and sodium nitrophenolate was 90:1; test 22: the effective ingredient mass ratio of semileaf and sodium nitrophenolate was 100:0.5; test 23: sodium nitrophenolate was replaced by sodium α-naphthaleneacetate, and the effective ingredient mass ratio of semileaf and sodium α-naphthaleneacetate was 35:2; test 24: the same amount of water was applied, which was the blank control group. Random five-point sampling method was used in each plot, 5 plants were investigated at each point, and 3~4 cucumber vines were selected from each plant. The length of cucumber, the weight of single cucumber, and the content of vitamin C (determined by 2, 6-dichloroindophenol titration method in GB 5009.86—2016) of different test groups of cucumber were counted, and the results are shown in Table 1. The total yield of cucumber in different test groups was counted, and the results are shown in Table 2. The yield increase rate in Table 2 was calculated according to the following formula:

[0025] Actual yield increase rate E (%) = [(yield of the pesticide treatment group-yield of the blank control group) / yield of the blank control group] x 100;

[0026] Theoretical yield increase rate E0 (%) of the two agents in combination application = X + Y - XY / 100;

[0027] In the formula, X represents the actual yield increase rate of the half leaf element when the dosage is A; Y represents the actual yield increase rate of the sodium complex of nitrophenol when the dosage is B; the combined action type of the mixture is evaluated according to the Gowing method in NY / T2061.5-2016, E-E0>10% is synergistic effect, E-E0<-10% is antagonistic effect, and the value of E-E0 is within ±10% is additive effect.

[0029]

[0030] As can be seen from Table 1, after half leaf element and sodium complex of nitrophenol are compounded according to the effective component mass ratio of 40-90:1-3.5, the cucumber length, single fruit weight and vitamin C content of cucumber are all improved, the cucumber length is increased by 20.7-28.5%, the single fruit weight of cucumber is increased by 21.7-27.8%, and the vitamin C content is increased by 4.8% at most. It is shown that the application of the agricultural composition of the present application can improve the quality of cucumber, and the effective component mass ratio of half leaf element and sodium complex of nitrophenol is 70:2, which has the best effect on improving the quality of cucumber. When the compounding ratio of half leaf element and sodium complex of nitrophenol changes, the improvement effect on the quality of cucumber also changes, and the application of half leaf element or sodium complex of nitrophenol alone also has a promoting effect on the improvement of the quality of cucumber, but the promoting effect is poorer than that of the agricultural composition compounded by the present application. It is shown that although half leaf element and sodium complex of nitrophenol are both plant growth regulators, the functions or regulation pathways are different, and the two can play a complementary effect when compounded. When the compounding ratio exceeds the range provided by the present application, the effect of the agricultural composition on improving the quality of cucumber becomes poor. When sodium complex of nitrophenol is replaced by α-naphthalene acetic acid sodium, the effect of the agricultural composition on improving the quality of cucumber is reduced.

When the ratio exceeds the ratio range provided by the application or the components of the agricultural composition of the application are changed, the yield-increasing rate on cucumbers shows the additive effect, and the effect is worse than that of the agricultural composition of the application.
