Microscope Slides And Cover Slips 1. The glass slide is used to put the sample to be tested, and the cover glass is covered on the sample to be tested.
6. The cover glass is square, the slide glass is rectangular, and the width is longer than the side of the cover glass.

Ma Yan said that during the solid waste composting process, after fermentation and decomposing, a large number of beneficial microorganisms such as actinomycetes, molds and some plant diseases are antagonized and the metabolites of these beneficial bacteria are produced. The compost is directly applied to the soil or used as a composting extract to inhibit the occurrence of plant-borne diseases through nutrient competition, antagonism, heavy parasitism and predation, and induction of plant disease resistance.
In response to the occurrence characteristics and pathogens of cucumber squatting disease, Ma Yan and other researchers screened more than 100 strains that had antagonistic effects on pathogens from the compost, and after repeated trials, excellent selection of a comprehensive trait was selected. Nematodes, labeled as A630. According to the test, A630 has a fast growth rate and sporulation speed, and is easy to breed; it can colonize well in the rhizosphere of cucumber, not only can produce anti-biomass, but also has strong nutritional competitiveness; broad spectrum of antibacterial, pathogen of cucumber, rapeseed Pathogenic bacteria such as Sclerotinia sclerotiorum have strong antagonistic effects; indoor laboratory results show that the control effect against cucumber mites can reach 50%-60%.
2. The glass slide is at the bottom, which is the carrier for the material you want to observe, that is, you want to put something on it.
3. The cover glass is smaller than the slide glass. The glass slide is mainly used to hold the observation objects. The cover glass is covered on the slide glass and used for fixing.
4. The glass slide is a thicker piece of glass in the transfer slide, which is used to carry the real object. The cover fragment is the small round or square thin one.
5. Mounting is a general term for a set of things, including slides, coverslips and loaded objects
Composting treatment is the most effective treatment method for solid waste such as livestock manure, urban township domestic garbage, crop straw, agricultural and sideline products processing waste, reduction, harmlessness and resource utilization. Ma Yan, a soil and fertilizer expert at the Resource and Environment Research Center of Jiangsu Academy of Agricultural Sciences, found through research that compost has a good fertilizer effect and “medicine effectâ€, which can inhibit the growth and reproduction of various soil-borne pathogens and stumble on cucumbers. Soil-borne diseases such as diseases have certain control effects.
