Abstract: The present invention relates to the technical field of gene engineering and particularly relates to a method for constructing non-de novo synthesized Mucor circinelloides recombinant strain with high lipid yield, recombinant strain constructed by method, and application of recombinant strain. According to the present invention, a diacylglycerol acyltransferase gene (DGAT) is overexpressed in Mucor circinelloides WJ11 by a homologous recombination technology, and exogenous oil is added for fermentation, such that the non-de novo synthesized Mucor circinelloides recombinant strain with high lipid yield is constructed. Compared with the control strain Mc2075, the fat yield of the Mucor circinelloides is increased; and when the diacylglycerol acyltransferase (DGAT) is transformed into the uracil defective type of Mucor circinelloides WJ11, the fatty acid composition changes after fermentation, and the lipid content may reach 53% of dry cell weight after the fermentation condition is optimized.

Abstract: The present invention discloses an opposite belt-type precise seeding device. The opposite belt-type precise seeding device comprises a seed metering tube consisting of a U-shaped shell and a cover plate, two conveying devices provided inside the seed metering tube in parallel, and a conveying plate provided at the lower end of the seed metering tube. The opposite belt-type precise seeding device belongs to the field of agricultural machinery. In a seeder, a tubular seed conveying tube is usually used for guiding movement of seeds, but the movement of the seeds in the seed conveying tube has certain randomness, so that the seed distance consistency of the seeds in a seed bed is reduced. Through control of the seeds by the conveying devices, the stable movement of the seeds is achieved and the seed distance consistency of the seeds in the seed bed is guaranteed.
