The invention relates to a growth regulator of a combination cotton of thidiazuron and ethephon, which is characterized by comprising the following components according to weight percentage: 45 to 90 percent of active ingredients of the thidiazuron and the ethephon and residual addition agent, wherein, the weight ratio of the thidiazuron and the ethephon is 1:2.5 to 5. The invention adopts osmotic agent of the addition agent, solid carrier, wetting agent and dispersant, etc. commonly used in the agricultural chemical field to be made into wetting powder formulation, the formulation can be used as plant growth regulator for the ripening and defoliation of cotton. The growth regulator of the invention has the advantages of good effects on the defoliation and ripening of cotton, improving the grade of cotton, increasing the output of cotton, especially the output before frost and improving the benefits of farmers.

The present invention provides a liquid catalyzing system for aging a liquid, such as alcoholic liquid, vinegar and soy sauce. Different from present catalyzing devices (or catalyst systems) catalyzing specific liquids with carrier-containing nanometer metal catalysts or carrier-free nanometer metal catalysts, the system adopts a plurality of nano metal flakes as the catalyst and a liquid catalyzing system is particularly designed for rapidly aging the liquid. By using the liquid catalyzing system, the liquid can be evenly mixed with the nano metal flakes in a reaction space constructed by a framework and a filter, and a gas circulation loop is connected to the framework, and therefore a disturb gas is inputted to the reaction space through the gas circulation loop for treating a liquid flow disturbance to the liquid and the nano metal flakes, so as to accelerate a catalytic reaction resulted from the nano metal flakes to the liquid.

The invention provides a parent crassostrea nippona breeding method for promoting maturity and spawning. The method comprises the steps of firstly, selecting and placing parent crassostrea nippona in a nursery pond for maturity-promoting breeding; feeding the parent crassostrea nippona with crassostrea nippona monodus subterraneus bait, and conducting maturity-promoting breeding on the crassostrea nippona by raising the temperature step by step, so that gonad of the parent crassostrea nippona achieves maturity; drying the parent crassostrea nippona achieving gonad maturity in the shade, and then placing the parent crassostrea nippona into a spawning pond; picking out female mature pacific oysters through microscopic examination, taking out ova through dissection, filtering the ova with a screen, and removing tissue fragments and pacific oyster ova, so that tissue filtered fluid is obtained; adding the tissue filtered fluid into the spawning pond, and inducing the parent crassostrea nippona to spawn and discharge seminal fluid; finally, moving away the parent crassostrea nippona, so that fertilized ova of artificial breeding are obtained. By means of the method, the problems that it is difficult for parent crassostrea nippona bred through indoor artificial maturation-promoting breeding to get mature and spawn can be solved, the parent crassostrea nippona spawns quickly, spawn quality is good, the artificial breeding production requirements for the crassostrea nippona are satisifed, and the foundation is laid for large-scale production of the crassostrea nippona.
