Bed soil several pieces are taken, pH value is determined.The assay method for the measure bed soil pH value that the present embodiment is used for test paper colorimetric method for determining,
Consumption bale-out goes out bed soil sample on a small quantity, is put into porcelain plate groove, adds light water a little, is sufficiently stirred for glass bar, treats clear
After clear, take a test paper to be tested, the test paper torn is stained with colorimetric immediately in porcelain groove, pH value is determined.If per 20g
Native pH value is 6.82-7.0 values, and the acidifying plant ash charcoal or acidifying cow dung amount of addition are just 0.9-1.2g；If being per 20g bed soil pH values
During 6.41-6.81 values, the acidifying plant ash charcoal or acidifying cow dung amount of addition are just 0.80-0.90g；If being per 20g bed soil pH values
During 6.01-6.40 values, the acidifying plant ash charcoal or acidifying cow dung amount of addition are 0.70-0.80g；If being 5.04- per 20g bed soils pH value
6.00 values, the acidifying plant ash charcoal or acidifying cow dung amount of addition are just 0.55-0.70g；If being 4.81-5.03 per 20g bed soils pH value
During value, the acidifying plant ash charcoal or acidifying cow dung amount of addition are just 0.40-0.55g, and the acid adjustment of a large amount of bed soils is carried out as standard.
The fertilising of present invention collection, acid adjustment, sterilization three are located at one, and actual tests prove that the rice shoot that the present invention is cultivated i.e. must not
It is sick and healthy and strong；Allotment program of the present invention is simple, and operation is easy, and manpower consumption is low, and modulation period is short, and yield is big, and economic benefit is received
It is beneficial obvious, it can be widely applied to rice seedling Cultivating techniques field.
In summary, only presently preferred embodiments of the present invention, not for limiting the scope that the present invention is implemented, it is all according to
The equivalent changes and modifications carried out by shape, construction, feature and spirit described in scope of the invention as claimed, all should be included in this
In the right of invention.
