Description
Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to an application of a plant growth regulator, namely sodium furoate, in preparation of a yield-increasing regulator for oil crops.
Background
Flowering and pollination are important links in the process of transforming the vegetative growth to reproductive growth of plants, and play a decisive role in crop yield. The process of plant blossoming and pollination is completed by the mutual integration of the growth regulator in the plant body and the external environment factors. Nutrient supply is insufficient if adverse weather is encountered during flowering and pollination of plants, resulting in reduced fruit set rate of plants and affecting crop yield. Therefore, promoting flowering at the right time by a plant growth regulator is crucial to improving crop yield.
At present, plant growth regulators commonly used for promoting flowering of crops are mainly of two types: gibberellin synthesis inhibitors and cytokinins. The gibberellin synthesis inhibitor is mainly used for inhibiting or delaying the early vegetative growth process of crops, more nutrients required by plant growth are prepared for reproductive growth, the effect of promoting flowering of the crops is achieved, and the gibberellin synthesis inhibitor mainly comprises paclobutrazol, uniconazole, prohexadione calcium and trinexapac-ethyl. Cytokinin mainly promotes development of meristem chloroplast, further improves light efficiency, promotes dry matter accumulation, provides sufficient nutrients for a flowering process of reproductive growth, achieves a yield increase effect, and mainly takes benzylaminopurine and furfurylaminopurine as main materials.
However, in the actual use process, people find that the two types of medicines still have various defects. For example, the pesticide residue period after the paclobutrazol and uniconazole are used is more than 2 years, and the growth of succeeding crops is seriously influenced. The prohexadione-calcium and trinexapac-ethyl have short lasting period of only about 10 to 30 days, and the whole growth cycle needs to be used for multiple times to achieve the purposes of delaying growth and promoting flowering. The benayl aminopurine and the furfuryl aminopurine have slow effect after being used, are greatly influenced by the environment in the period, need to be applied for many times, and consume a large amount of manpower and material resources.
In order to improve the current state of the prior art, the invention provides a pesticide preparation with the active ingredient of the nafion, and the pesticide preparation can promote oil crops to bloom and further has an obvious yield increase effect on the oil crops.

Application example 1 peanut field efficacy test
The test peanut variety is Tianfu peanuts, the test place is Pingquan Zhenhuan in Jianyang city of Sichuan province, the peanuts are planted in rows, the row width is 40 cm, the pit spacing is 30 cm, 17 test cells are randomly divided, and the peanuts are planted at the same time. Wherein 5 cells apply the pesticide once in the 1-4 leaf stage of the peanut, 5 cells apply the pesticide once in the 4-8 leaf stage of the peanut, and 5 cells apply the pesticide once in the 8-12 leaf stage of the peanut. The 16 th cell is a control, paclobutrazol with the effective concentration of 50ppm is applied for 3 times in the 1-4 leaf stage, the 4-8 leaf stage and the 8-12 leaf stage of the peanut respectively, the last test field is used for a blank Control (CK), and purified water is sprayed in the 1-4 leaf stage, the 4-8 leaf stage and the 8-12 leaf stage of the peanut.
Preparing the medicine: the 5% by mass nafion soluble solution prepared in example 1 of the invention is respectively diluted with purified water to obtain the medicine with nafion active ingredient concentrations of 1, 5, 25, 50 and 200ppm, and the medicine is applied in a foliar spraying manner.
Reference to NYT1464.76-2018 pesticide field efficacy test guidelines part 76: the plant growth regulator is used for promoting the growth of peanuts, the pod bearing number and the kernel yield of each peanut plant are recorded after the peanuts are ripe, the acre yield of each peanut plant is calculated, and the average value is calculated, wherein the specific result is shown in the following table.
TABLE 5 peanut field efficacy test data
As can be seen from the data in the table above, the effect of the administration in the 4-8 leaf stage of peanut is better than the effect of the administration in the 1-4 leaf stage and the 8-12 leaf stage. The reason is that the flower buds of the peanuts differentiate after the 4-leaf stage, and the administration can timely adjust the flower bud differentiation of the peanuts, promote the flowering and finally increase the peanut yield. During the peanut 4-8 leaf period, when the concentration of the effective components of the medicine is 1-50ppm, the effect is obvious, the increase of the medicine concentration has no obvious influence on the pod bearing number of each plant of the peanut, the kernel yield and the yield per mu, and the preferable application concentration of the peanut is 1-50ppm on the principles of environmental protection and resource saving, wherein the application concentration of 25-50ppm is preferable, and the optimal application concentration is 25 ppm. Compared with the method that the number of pods of a single peanut plant planted in the paclobutrazol test field is 11.5, the kernel yield is 60%, the yield per mu is 348 kg, the yield increasing effect of the paclobutrazol on the peanuts is not as good as that of the naftidrofuryl, and the paclobutrazol is applied for 3 times, so that the labor cost is higher. The number of the pods of the peanut single plant harvested in the blank control test field is 9.9, the kernel yield is 59 percent, and the yield per mu is 311 kg the lowest. As shown in figure 1, the left one is a peanut map in a 4-8-leaf-stage pesticide application test field, the concentration of the active ingredient of the sodium furoate is 50ppm, compared with a blank control and a single peanut applied with paclobutrazol, the single peanut has more pod bearing number, and the peanut has tidy and full grains.
Application example 2 sunflower field efficacy test
The test uses edible dwarf sunflower as the sunflower, and the test places are Hitachi Staphyli county, sandy loam and two lines per ridge, and the planting density is about 1200 plants/mu. And randomly dividing 16 test fields to plant sunflowers. Wherein 5 of the above drugs are applied once in the 3-8 leaf stage of sunflower, 5 of the above drugs are applied once in the 8-12 leaf stage of sunflower, and 5 of the above drugs are applied once in the 12-18 leaf stage of sunflower. Another field was used as a blank Control (CK) and pure water was sprayed at the 3-8 leaf stage, 8-12 leaf stage, and 12-18 leaf stage of sunflower.
Preparing the medicine: the 5% by mass nafion soluble solution prepared in example 1 of the present invention was diluted with purified water to obtain a drug with nafion active ingredient concentrations of 10, 20, 50, 100, and 200ppm, and applied by foliar spray.
After the sunflower is ripe, the seed number and the kernel yield of a single sunflower plant are recorded, the per mu yield of the sunflower plant is calculated, and the average value is calculated, wherein the specific results are shown in the following table.
TABLE 6 sunflower field efficacy test data
As can be seen from the data presented above, the effect of the administration at the 8-12 leaf stage of sunflower is superior to the effect of the administration at the 3-8 leaf stage and 12-18 leaf stage. When the concentration of the effective components of the medicine is 50-200ppm, the effect of the naftidrofuryl acid on increasing the yield of the sunflower is best. Wherein, the concentration of the naftidrofuryl acid is 100-200ppm as the proper concentration, and the concentration of 100ppm as the optimal concentration. The diameter of the sunflower discs planted in the blank control test field is 23.0 cm, the kernel yield is 37 percent, the yield per mu is 207 kg, and the yield is obviously lower than that of any test field applying the naftidrofury acid in the table.
In addition to the field efficacy test of oil crops such as peanut and sunflower, the inventor also carried out the field efficacy test of non-oil crops such as litchi, the clomazone sodium solution with the effective concentration of 20ppm is given in the early heading period, and the control test is that gibberellic acid with the effective concentration of 10ppm is given. The final test result shows that the yield increasing and promoting effects of the nafion on litchi are not obviously different from that of gibberellic acid. Therefore, the inventor proves through experiments that the low-concentration sodium furoate (1-200ppm) has obvious yield-increasing effect on oil crops, has no obvious yield-increasing effect on non-oil crops, and has better yield-increasing effect after the application time is optimized.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
