[0039] Example: Identification of key microorganisms that hinder corn stalk carbon assimilation in yellow cinnamon soil
[0040] 1. Materials and methods
[0041] 1.1 Collection of soil samples
[0042] Taking the yellow cinnamon soil wheat-corn rotation system as the research object, the experimental site is located in the Modern Agriculture Demonstration Park of Zhaohe Town, Fangcheng County, Henan Province (33°08′N, 112°58′E), which is in the subtropical continental climate zone. The average sunshine hours are 2092 hours, the average annual temperature is 14.4 ℃, the average annual rainfall is about 803.9 mm, and the frost-free period is 220 days. The test started in the 2012 wheat season, and the organic matter of the test soil (0-20cm) before the test was 22.83 g kg -1 , alkaline hydrolysis nitrogen, available phosphorus and available potassium were 191.0, 46.6 and 99.0 mg kg -1 , pH 5.92. Residential Area 49 m 2 , repeated 3 times, arranged in random blocks. Select o...
