Abstract

A trailed straw biomass granulator includes a first drive device and a forming device. The forming device includes a driving gear and a forming gear. The driving gear is evenly distributed with involute drive teeth along a circumference. A storage groove is formed between every two adjacent drive teeth. The driving gear includes an output hole in an axial direction, and an auger is arranged inside the output hole. A forming hole is defined between two adjacent drive teeth, and the forming hole penetrates into the output hole and the storage groove. The forming gear includes a base body, multiple involute sliding teeth and multiple reset springs, and the sliding teeth are evenly distributed on the peripheral side of the base body in a circumferential direction. The base body includes multiple sliding grooves in one-to-one correspondence with the sliding teeth, which are integrally formed with a slide block.

Abstract

Provided are a nitrogen-fixing compound bacterial system comprising nitrogen-fixing bacteria and non-nitrogen-fixing bacteria, and an application thereof, the nitrogen-fixing bacteria comprising Klebsiella MNAZ1050, Citrobacter MNAZ1397 and Pseudomonas MNAZ228, and the non-nitrogen-fixing bacteria comprising Acinetobacter ACZLY512 and Klüvorella AZ981. The nitrogen-fixing bacteria in the nitrogen-fixing compound bacterial system have a relatively good nitrogen-fixing effect when used alone, while the cooperative use of the nitrogen-fixing bacteria and the non-nitrogen-fixing bacteria to construct a nitrogen-fixing compound bacterial system has a more significant nitrogen-fixing effect than when the nitrogen-fixing bacteria are used alone, which can promote crop growth under conditions in which nitrogen application is significantly reduced.

Abstract

The present invention relates to a preparation method for an alginic acid synergistic carrier for reducing urea conversion. The preparation method comprises steps such as preparation of an alginic acid organic extract agent, preparation of an alginic acid extract solution and preparation of an alginic acid synergistic carrier. The combination of the alginic acid synergistic carrier with urea can significantly slow the decomposition, release and conversion speed of urea, the urea residue ratio being increased by 90% compared with the commercially available urea, and can enhance the sustained release of urea by influencing fertilizer processes such as the pH of the urea conversion, the soil pH within 1 cm of a fertilizer being decreased by 0.3-1.1 units compared with commercially available urea. The fresh weight and viability of an alginic acid synergistic carrier treated wheat root system respectively increase 54.9% and 36.3% in average compared to the control, and the fresh weight and viability of a corn root system respectively increase 38.5% and 26.7%.
