First, compounding between plant growth regulators In the past, everyone thought that plant growth regulators were specific and could not be used in combination. Modern plant physiology studies have shown that different combinations of plant growth regulators will produce unexpected and good results. The use of growth promoters and growth inhibitors has shown that for some plants, it can inhibit vegetative growth and promote reproductive growth. When the plants are prosperous and resistant to lodging, the fruits are enlarged and the yield is improved. 1, sodium nitrophenolate sodium naphthalene acetate It is a new type of compound plant growth regulator with low labor cost, high efficiency and high quality. Sodium nitrophenolate, as a regulator that comprehensively regulates the balance of crop growth, can promote the growth of crops in general and is compounded with sodium naphthaleneacetate. On the one hand, it strengthens the rooting action of sodium naphthalate, and on the other hand, it enhances the fast-acting properties of sodium nitrophenolate. Both promote the rooting effect faster, and absorb nutrients more strongly and more comprehensively, accelerating the growth of crops, strengthening and not lodging. , Staggering between festivals, increased branches, childbirth, resistance to disease, resistance to lodging. According to a number of scientific research units, a joint experimental study showed that sodium nitroprusside and sodium naphthaleneacetate were compounded in a ratio of 1:3 and applied to rootstock rooting. The results showed that the rooting number was significantly higher than that of sodium naphthaleneacetate alone; Experiments on soybeans showed that both of them significantly promoted the growth of soybean roots, and the ability of root nodule azotobacteria was significantly enhanced, and the apparent direct-viewing effect was apparent in 2-3 days. The test results show that the use of sodium nitrophenolate sodium and sodium naphthalene acetate 2000-3000 times solution in the wheat rooting phase spraying 2-3 times, can increase production by 15%, no adverse effects on the quality of wheat. 2, DA-6 + ethephon (or sodium nitroprusside + ethephon) It is a dwarf, robust, and anti-drop type regulator for corn in compound corn. Single use of ethephon, showed dwarfing effect, and leaves widened, dark green leaves, leaves up, secondary roots increased, but prone to leaf premature aging. Application of corn DA-6 + ethephon compound control Wang, compound use than ethephon alone can reduce the strain up to 20%, with significant efficiency, anti-premature efficacy. 3, sodium nitroprusside + gibberellin Both sodium nitroprusside and gibberellin were used as fast-acting regulators, all of which acted in a short period of time after application, so that the crop showed a good growth effect, while the compound sodium nitroprusside was used together with gibberellin, according to Chinese The application of sodium nitropylate in the Jujube Science Research Institute shows that: In addition to the combined effect of both, the sustained-release characteristics of sodium nitroprusside can complement this defect of gibberellin, and at the same time, through comprehensive regulation of growth balance, avoiding damage to the plant body caused by excessive use of gibberellin. The jujube tree significantly increased production and quality was significantly improved. 4, sodium naphthyl acetate + barium butyrate It is the most widely used compound rooting agent in the world and is widely used in fruit trees, trees, vegetables, flowers and some ornamental plants. The mixture can be absorbed through the roots, leaves, and germinating seeds to stimulate cell division and growth in the inner sheath of the root, so that the lateral roots grow faster and more, and the ability of the plants to absorb nutrients and water is increased, and the overall growth of the plants is robust. As the agent is often used to promote the cutting or rooting of plants in cuttings, some hard-to-root plants can also be rooted. Second, plant growth regulators and fertilizers 1. Sodium nitrophenolate + urea Sodium nitrophenolate + urea can be described as a "golden partner" in the formulation of regulators and fertilizers. In terms of effect and effect, the comprehensive regulation of crop growth and development characteristics by sodium nitrophenolate can make up for the lack of early nutrient requirements, make crop nutrition more comprehensive, and use urea more thoroughly; At the time of action, the fast-acting and sustained effects of sodium nitroprusside combined with the rapid availability of urea resulted in faster and longer-lasting changes in plant appearance and intrinsic changes. In the method of action, combined use of sodium nitrophenolate and urea, can be used as base fertilizer, can also be used as a root spray, fertilization, can be described as "three goals." The test results of sodium nitroprusside and urea-containing foliar fertilizers showed that the leaves darkened green and shiny within 40 h after application, and the yield was significantly increased in the later period. 2. Triacontanol + Potassium dihydrogen phosphate Triacontanol can increase the photosynthesis of crops, and it can be mixed with potassium dihydrogen phosphate to increase crop yield. The combination of the two re-targets with other fertilizers or regulators can be applied to the corresponding crops. For example, the use of triacontanol + potassium dihydrogen phosphate + sodium nitroprusside in soybeans can increase production by more than 20% compared with the former only. 3, DA-6 + trace elements + N, P, K DA - 6 and a large number of elements and trace elements of the application of hundreds of test data and market feedback information : DA - 6 + trace elements such as zinc sulfate ; DA-6+ large amounts of elements such as urea, potassium sulfate, etc., all make the fertilizer more than a few times more effective than single use, while enhancing plant resistance to disease and stress resistance. 4, Chlorocholine + boric acid The use of this mixture on grapes can overcome the deficiency of chlormequat. Experiments have shown that spraying the whole plant with a certain concentration of chlormequat on the 15th day before flowering can greatly increase the yield of the grapes, but it reduces the sugar content in the grape juice. However, the mixture can not only exert the effect of controlling the long-term growth of the fruit by increasing the yield of the fruit, but also can overcome the side effect of decreasing the sugar content after the use of the chlormechanin. Third, plant growth regulator + fungicide 1. Sodium nitrophenolate + Ethyl iodide The use of compound sodium nitroprusside and ethyl allicin can significantly improve its efficacy and delay the occurrence of drug resistance. It can also prevent the damage caused by overdose or high toxicity by regulating crop growth. The trials of sodium nitroprusside and ethyl allicin EC in the prevention and control of cotton leaf wilt showed that the incidence of sodium nitrophenolate addition was 18.4% lower than that of ethyl iodide alone. The complex formulation treatment was stronger than the control cotton, and the leaves were dark green and hypertrophic. The late decay time was later and the leaf functional period was prolonged. 2, sodium nitrophenolate + carbendazim The combination of sodium nitropate with fungicides improves the surface activity of the agents, increases penetration and adhesion, and thus increases the bactericidal effect. Sodium nitrophenolate and heterocyclic bactericides, such as carbendazim, are used in the prevention and treatment of peanut leaf disease. The initial stage of the disease is sprayed twice and the control effect is improved by 23%, which significantly enhances the bactericidal effect. 3, Brassinolide + Triadimefon Brassinolide can promote the germination of crops, trees and seeds, and the growth of seedlings and improve the resistance of crops. According to relevant literature reports, the control effect of brassinolide and triadimefon on cotton shoot blight is over 70%, and at the same time it promotes the growth of cotton roots and buds. The study also showed that salicylic acid has a significant synergistic effect on triadimefon. IV. Plant growth regulators + herbicides Ethephon + paraquat (first nationally banned product) For crop defoliants. The agent can increase the yield when used as a sesame drying defoliant, and sprayed with ethephon only 6 days before the sesame harvest, and the dry defoliation effect is poor. Sesame also does not increase production. The single use of paraquat has a good effect of drying and defoliating, but it does not increase production. If the two are used together, they not only show a good dry and defoliant effect, but also increase the production of the product compared to the control.
