Description

Technical Field

[0001] The invention belongs to the technical field of plant growth regulators and relates to an agricultural composition containing hemichlorothiazide and sodium nitrophenolate. Background Art

[0002] The chemical name of bacillin is (6-benzylamino) adenine, abbreviated as BA. It is a kind of purine hormone and was originally a pharmaceutical intermediate with a protective effect on myocardial ischemia. In recent years, studies have found that bacillin is an effective plant growth regulator and protective agent, which has the functions of promoting root development, enhancing crop stress resistance, and increasing yield. Bacillin mainly acts on the cell division and growth process of plants, promotes the synthesis and accumulation of substances such as proteins, nucleic acids and alkaloids in plants, and can also affect the hormone balance in plants and improve the adaptability of plants to the environment. Bacillin can be applied to fruit trees, which can promote the luxuriant branches of fruit trees, the rapid differentiation of flower buds, stimulate the expansion of fruits, promote the division of pulp cells, increase the sugar content of fruits, and improve the quality and taste of fruits.

[0003] Sodium nitrophenolate, also known as sodium nitrophenolate, is composed of sodium p-nitrophenolate, sodium o-nitrophenolate and sodium 5-nitroguaiacol. It is a powerful cell activator. After contacting with plants, it can quickly penetrate into the plant body, promote the protoplasm flow of cells, and improve cell vitality. Sodium nitrophenolate, as a plant growth regulator, can accelerate the growth rate of plants and has a strong promoting effect on the vegetative growth and reproductive growth of plants. It can be widely used to promote plant growth and development, break dormancy, bloom early, promote germination, prevent falling flowers and fruits, improve product quality, and improve the disease resistance, insect resistance, drought resistance, waterlogging resistance, cold resistance, salt resistance, lodging resistance and other stress resistance of crops. Sodium nitrophenolate is widely used in food crops, cash crops, vegetables, fruits, fruit trees, oil crops and flowers, etc. It has the advantages of high efficiency, low toxicity, no residue, wide range of application, no side effects, and wide range of concentration.

[0004] Different plant growth regulators have different mechanisms of action. When a certain agent is used alone, it often increases the yield while producing side effects on the crop quality, which fails to meet the requirements for improving the quality. Therefore, two or more plant growth regulators need to be mixed, which can complement each other and overcome the shortcomings of single use. Due to the different directions of action of hemifoliin and sodium nitrophenolate, there is no report on compounding hemifoliin and sodium nitrophenolate to regulate crop growth in crop production practice. Therefore, it is of great significance to develop a compound plant growth regulator with hemifoliin and sodium nitrophenolate as active ingredients, which can promote the growth and development of crops and improve the yield and quality of crops. Summary of the invention

[0005] In order to develop an agricultural composition with hemichlorophylline and sodium nitrophenolate as effective ingredients to promote crop growth and development and improve crop yield and quality, the present invention provides an agricultural composition containing hemichlorophylline and sodium nitrophenolate. The effective ingredient mass ratio of hemichlorophylline and sodium nitrophenolate in the agricultural composition is 40-90:1-3.5. Within the ratio range provided by the present invention, the agricultural composition has a good improvement on the yield and quality of cucumbers, and the agricultural composition provided by the present invention also has a synergistic effect on the improvement of cucumber yield.

[0006] To achieve the technical purpose of the present invention, on the one hand, the present invention provides an agricultural composition, the active ingredients of which are composed of silymarin and sodium nitrophenolate. The effective ingredient mass ratio of silymarin and sodium nitrophenolate in the agricultural composition is 40-90:1-3.5; preferably, the effective ingredient mass ratio of silymarin and sodium nitrophenolate in the agricultural composition is 60-80:1.5-2.5; further preferably, the effective ingredient mass ratio of silymarin and sodium nitrophenolate in the agricultural composition is 70:2.

[0007] It is easy for a person skilled in the art to know that in order to give full play to the efficacy of the active components of plant growth regulators (pesticides), they can be prepared into a formulation that is easy to use according to the needs of use. The agricultural composition is processed into an agriculturally accepted formulation, and the formulation contains an auxiliary agent that assists the semi-leaflet and sodium nitrophenolate in regulating crop growth. The agricultural composition can be formulated into a variety of formulations such as water, soluble liquid, water-dispersible granules, wettable powder, dispersible oil suspension, suspension, microemulsion, granules, and microcapsules with a certain sustained release effect. When preparing the above-mentioned different formulations, for a person skilled in the art, in addition to the need to use the plant growth regulator active ingredients to be selected, it is also necessary to select a variety of auxiliary agents, and different formulation auxiliary ingredients (auxiliaries) can be selected and used according to needs. The auxiliary ingredient can be one or more of a dispersion medium, a dispersant, an emulsifier, a wetting agent, a thickener, a defoamer, an antifreeze, a disintegrant, a binder, a filler, a carrier, etc.

[0008] On the other hand, the present invention seeks to protect the use of the above-mentioned agricultural composition in improving the quality of cucumbers, and improving the quality of cucumbers includes increasing the length, single cucumber weight and vitamin C content of cucumbers.

[0009] Furthermore, after applying the agricultural composition to cucumbers, the present invention found that after compounding the effective component mass ratio of hemichlorothiazol and sodium nitrophenolate at 40-90:1-3.5, the cucumber length, single cucumber weight and vitamin C content were all improved, the cucumber length increased by 20.7-28.5%, the single cucumber weight increased by 21.7-27.8%, and the vitamin C content increased by up to 4.8%. It shows that the application of the agricultural composition of the present invention can improve the quality of cucumbers, and the effect of improving the quality of cucumbers is best when the effective component compound mass ratio of hemichlorothiazol and sodium nitrophenolate is 70:2.

[0010] Furthermore, the present invention claims protection for the use of the above agricultural composition in increasing crop yield, wherein the crop is cucumber.

[0011] Furthermore, after the present invention applies the agricultural composition to cucumber, it is found that it also has a synergistic effect within the ratio range provided in the present application. The effective components of hemifoliin and sodium nitrophenolate have a yield-increasing effect on cucumbers after compounding in the ratio range of 40-90:1-3.5, and 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 within the ratio range is greater than 10%, showing a synergistic effect; when the effective components of hemifoliin and sodium nitrophenolate are in the ratio range of 60-80:1.5-2.5, the agricultural composition has a better yield-increasing effect on cucumbers, 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%, and the synergistic effect is better; when the effective component ratio of hemifoliin and sodium nitrophenolate is 70:2, the synergistic effect is the best, and the difference between the actual yield-increasing rate and the theoretical yield-increasing rate is 17.27%.

[0012] The objects of use of the agricultural composition containing hemichlorophenate and sodium nitrophenolate are fruit crops that need to promote growth or improve quality. More preferably, the fruit crops are cucumber fruits. Based on the inspiration or ideas of the technical solution of the present invention, the objects of use of the agricultural composition containing hemichlorophenate and sodium nitrophenolate can be further expanded to fruits and vegetables.

[0013] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects or advantages:

[0014] The agricultural composition containing silymarin and sodium nitrophenolate of the present invention has the effect of improving the quality of cucumbers. After silymarin and sodium nitrophenolate are compounded according to the effective component mass ratio of 40 to 90:1 to 3.5, the cucumber length, single cucumber weight and vitamin C content are all improved. The cucumber length increases by 20.7 to 28.5%, the single cucumber weight increases by 21.7 to 27.8%, and the vitamin C content can be increased by up to 4.8%. It shows that the application of the agricultural composition of the present invention can improve the quality of cucumbers, and the effect of improving the quality of cucumbers is best when the effective component compounding mass ratio of silymarin and sodium nitrophenolate is 70:2. When the compounding ratio of hemichlorophenoxylate and sodium nitrophenolate changes, the effect of improving the quality of cucumbers also changes accordingly. The application of hemichlorophenoxylate or sodium nitrophenolate alone also has a promoting effect on improving the quality of cucumbers, but the promoting effect is worse than that of the compounded agricultural composition of the present invention, indicating that although hemichlorophenoxylate and sodium nitrophenolate are both plant growth regulators, they play different roles or regulate different pathways, and compounding the two can better play a complementary role; when the ratio range provided by the present invention is exceeded, the effect of the agricultural composition on improving the quality of cucumbers becomes worse; after sodium nitrophenolate is replaced by sodium α-naphthylacetate, the effect of the agricultural composition on improving the quality of cucumbers is reduced.

[0015] The agricultural composition containing silymarin and sodium nitrophenolate of the present invention has the effect of increasing the yield of cucumbers, and also has a synergistic effect within the ratio range provided in the present application. After the effective components of silymarin and sodium nitrophenolate are compounded in the ratio range of 40-90:1-3.5, the yield of cucumbers can be increased by the agricultural composition, and the yield increase rate of cucumbers is 24.35-41.53%, and the difference between the actual yield increase rate and the theoretical yield increase rate within the ratio range is greater than 10%, showing a synergistic effect; when the effective components of silymarin and sodium nitrophenolate are in the ratio range of 60-80:1.5-2.5, the agricultural composition has a better yield increase effect on cucumbers, 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%, and the synergistic effect is better; when the effective component ratio of silymarin and sodium nitrophenolate is 70:2, the synergistic effect is the best, and the difference between the actual yield increase rate and the theoretical yield increase rate is 17.27%. When the proportions are beyond the range provided by the present invention or the components of the agricultural composition of the present invention are changed, the yield increase rate of cucumbers shows an additive effect, and the effect is worse than that of the agricultural composition of the present invention.

It shows that the application of the agricultural composition of the present invention can improve the quality of cucumbers, and the effect of improving the quality of cucumbers is best when the effective component mass ratio of hemichlorothiazol and sodium nitrophenolate is 70:2. When the compounding ratio of hemichlorophenoxylate and sodium nitrophenolate changes, the effect of improving the quality of cucumbers also changes accordingly. The application of hemichlorophenoxylate or sodium nitrophenolate alone also has a promoting effect on improving the quality of cucumbers, but the promoting effect is worse than that of the compounded agricultural composition of the present invention, indicating that although hemichlorophenoxylate and sodium nitrophenolate are both plant growth regulators, they play different roles or regulate different pathways, and compounding the two can better play a complementary role; when the ratio range provided by the present invention is exceeded, the effect of the agricultural composition on improving the quality of cucumbers becomes worse; after sodium nitrophenolate is replaced by sodium α-naphthylacetate, the effect of the agricultural composition on improving the quality of cucumbers is reduced.
