[0060] Example 1:
[0061] An ecological treatment method for agricultural non-point source pollution in rice planting areas is as follows:
[0062] A. Divide the demonstration area with an area of 10,000 mu into 10 blocks, and divide the ponds and weirs and ecological ditches in the entire demonstration area into sections for treatment and ecological restoration. The process flow and the overall flow are shown separately figure 1 with figure 2 .
[0063] B. The first line of defense: From the perspective of high rice yield, carry out source control of water-saving irrigation and reasonable fertilization, namely comprehensive regulation of water and fertilizer. The specific methods are as follows image 3 Shown. Intermittent irrigation is used in the paddy field, and a 10-40mm water layer is maintained during the rice greening period. The field is dried for 3-7 days at the end of the tillering stage, and the yellow maturity period is naturally dried out; in the rest of the stage,...
