Synergic regulator for cultivation of sound cotton seedlings by nutrition pots and application of synergic regulator

Abstract

The invention discloses synergic regulator for cultivation of sound cotton seedlings by nutrition pots and application of the synergic regulator. The synergic regulator comprises, by weight percent, 62.5% of 1, 1-dimethyl piperidine chloride, 25% of 1-methylcyclopropene and 12.5% of abscisic acid. The regulator is prepared into synergic regulator solution which is applied in the one-leaf and one-core period of cotton seedlings, the synergic regulator solution is sprayed to a seedling bed for cotton nutrition pots, concentration of the DPC in the synergic regulator solution is 100ppm, concentration of the abscisic acid in the synergic regulator solution is 20ppm, and concentration of the 1-methylcyclopropene in the synergic regulator solution is 40ppm. 1.6g of the synergic regulator solution is sprayed per mu of seedling bed. Obtaining of materials for the synergic regulator is scientific, preparation ratio is reasonable, and the novel cotton seedling growth regulator is capable of quickening leaf emergence for the cotton seedlings, promoting growth and development of cotton, shortening seedling raising time, inhibiting overgrowth of stem and leaf and promoting root amount and activity to form sound seedlings.

Description

technical field [0001] The invention relates to a plant growth regulator, in particular to a synergistic regulator for cultivating strong seedlings in a cotton nutrient bowl and an application thereof, belonging to the technical field of agricultural cultivation. Background technique [0002] At present, cotton in the entire southern cotton area of ​​my country is mainly planted in a nutrient pot seedling transplanting method. In this seedling raising method, cotton seeds are sown on a nutrient pot seedbed, protected and grown under a plastic film cover, and transplanted when 3 to 4 true leaves grow. Planted a large field and won the prime time season of more than one month. The benefits of growing seedlings in nutritional pots lie in the characteristics of saving seedlings, strong seedlings, and high yield. Generally, it is about 3 times less seedling than direct seeding. At present, the cotton seeds planted on one mu of land in the south are about 0.7 catties. In the north...

Problems solved by technology

[0003] The purpose of the present invention is to provide a synergistic regulator for growing cotton seedlings in a nutritional bowl for growing strong seedlings for the problems that need to be solved, such as slow leaf emergence speed and high plant height of cotton seedlings after the traditional cotton nutrient pot seedling cultivation seedbed growth regulator is applied. And its application method, the first is to solve the problem of slow leaf emergence of cotton seedlings, so that the growth and development of cotton can be promoted, and the time for seedling cultivation can be shortened; Form strong seedlings
