Biogas residue and biogas slurry are called biogas fertilizers. It is a high quality and efficient organic fertilizer and has been widely used in agricultural production. Under the same input of nitrogen, phosphorus and potassium nutrients, biogas fertilizer and biogas slurry have significant effects in combination with fertilization, which can effectively promote the vegetative growth and reproductive growth of strawberry, increase the single fruit weight, increase the yield, and improve the fruit quality. increase income. Before the strawberry is planted, 5,500 kilograms of biogas fertilizer is applied as a basal fertilizer for each acre. One week after the planting, a 1:1 (biogas slurry: fresh water) 5,000 kg of biogas slurry is used for the first rhizome dressing, and after half months, the above Methods The second rhizosphere top-dressing was performed. During the fruiting period of the strawberry, 45 kg of 1:2 biogas slurry per acre was used for foliar dressing, once every 10 days for a total of 4 times.
Black and White Ultrasound Scanner
"Black and White Ultrasound Scanner" is to emit ultrasonic waves, so that the ultrasonic waves encounter barriers to generate echoes, use the computer to collect these echoes, convert them into corresponding images and display them on the screen, and the images measured by the ultrasonic probe are black and white, so it is called " Black and White Ultrasound Scanner" is also the earliest diagnostic technology adopted by b-ultrasound.
"Black and White Ultrasound Scanner" has the advantages of non-invasive, high sensitivity, low cost and convenient operation
