Specific embodiment
The invention will be further described with reference to the accompanying drawings and embodiments.
Embodiment 1
More batches of romaine lettuce are planted with compound fertilizer improvement severe acidification agricultural land soil.
The preparation of the compound fertilizer of long-acting type improvement acidified soil：Attapulgite clay is be derived from Xuyi Jiangsu natural recessed
Convex stick stone clay, peat are the natural peat for being derived from northeast Jilin, attapulgite clay and peat are air-dried respectively, then
It crushes, crosses 10 mesh and 5 mesh sieve respectively, respectively obtain attapulgite clay powder and peat clast；By attapulgite clay
Powder and peat clast by mass percentage 1:1 ratio is matched, and is thoroughly mixed uniformly, and long-acting type improvement acid is made
Change the compound fertilizer of soil.
