CN-117652499-B - Method for promoting sugarcane to bud ahead of time by using trichostatin A

Abstract

The invention discloses a method for promoting sugarcane to bud ahead of time by using trichostatin A, and relates to the technical field of sugarcane planting. The invention uses 0.1-1uM/L trichostatin A aqueous solution, bactericide and adhesive to soak sugarcane seed stems, and then carries out conventional planting, wherein the addition of the bactericide is 0.5-1% of the weight of the trichostatin A aqueous solution, and the addition of the adhesive is 1-4% of the weight of the trichostatin A aqueous solution. The method can lead the sugarcane budding time to be 3 days earlier and the budding uniformity to be higher.

Description

Method for promoting sugarcane to bud ahead of time by using trichostatin A Technical Field The invention relates to the technical field of sugarcane planting, in particular to a method for promoting sugarcane to bud early by using trichostatin A. Background Sugarcane, also known as sugar cane, potato cane, a perennial herb subtropical crop is planted and produced in large quantities in Guangxi, guangdong, yunnan and other areas of China. The sugarcane has rich nutrient substances and wide application, can be directly eaten as special fruits, is sweet and delicious, has very high economic value and wide application prospect in industry, is used for preparing sugar, synthetic paper, sugarcane vinegar and the like, and can also be used for producing bioethanol, alcohol gasoline, generating electricity by utilizing bagasse and the like. Sugar cane sugar accounts for about 94% of the total yield of sugar in China, is an important economic crop in tropical and subtropical areas of China, and is an important economic source for increasing income of peasants. Researches show that the sugarcane bud is beneficial to the growth of main stems of the sugarcane earlier, and is beneficial to the formation of stems by more tillers, so that the yield of the sugarcane is improved. The sugarcane generally takes 7-10 days to sprout under natural conditions, and in order to lead the sugarcane to sprout early, lime water, warm water, auxin sodium naphthalene acetate or gibberellin are mainly adopted for treatment in current production. Lime water and warm water treatment budding is slightly earlier, but budding uniformity is low, and auxin sodium naphthalene acetate or gibberellin can accelerate early budding, but the use effect is easily influenced by external conditions such as illumination, temperature and the like, so that the use effect is different. Therefore, it is of great importance to find a stable method for promoting early sprouting of sugarcane. Disclosure of Invention In order to overcome the defects, the invention provides a method for promoting sugarcane to bud early by using trichostatin A, which can lead the sugarcane to bud early by more than 3 days and has higher bud uniformity. The specific technical scheme is as follows: A method for promoting sugarcane to bud early by using trichostatin A comprises the steps of immersing sugarcane seed stems in trichostatin A aqueous solution with the concentration of 0.1-1uM/L, and then carrying out conventional sowing and planting, wherein the bud eyes are upward during sowing, so that the sugarcane budding is more beneficial to soil emergence. Further, the purity of the trichostatin A is more than or equal to 98 percent. Further, the soaking temperature is 22-26 ℃ and the pH is 6-8. Further, the soaking time is 10-15h. Further, the method further comprises adding a bactericide and an adhesive to the trichostatin a aqueous solution. Further, the bactericide is one of prochloraz, carbendazim or difenoconazole. Further, the adhesive is mainly formed by mixing polyvinyl alcohol and starch substances in a weight ratio of 1:0.1-0.3. Further, the addition amount of the bactericide is 0.5-1% of the weight of the trichostatin A water solution. Further, the addition amount of the adhesive is 1-4% of the weight of the trichostatin A aqueous solution. Trichostatin a is an effective Histone Deacetylase (HDAC) inhibitor, and is also an antifungal antibiotic, with the property of inducing cell differentiation. Polyvinyl alcohol is an organic compound, having hydrophilicity and film forming property. The soaking of the sugarcane seed stems by the trichostatin A aqueous solution is generally carried out before sowing, the safety of medication is required to be paid attention to during the soaking, the dosage is not required to be increased without permission, and the sugarcane seed stems can be immediately used for sowing after the soaking. Compared with the prior art, the method has the beneficial effects that the sugarcane budding time can be shortened by more than 3 days, and the budding uniformity is higher. Wherein, trichostatin A can relieve dormancy, promote sugarcane cell differentiation, and the bactericidal agent can assist killing sugarcane harmful fungus on the seed shaft, and the adhesive can make the seed shaft keep moist to make trichostatin A adhere on the seed shaft, promote trichostatin A can exert long-term effect, and then promoted the early germination.
