2. Fieldwork: The field should dig various shapes of trenches, with a small area dug into "field" characters, large digging and forming, 30 to 40 centimeters deep, 40 to 50 centimeters wide, and a deep 30 around the excavation. - 40 cm wide and 40-50 cm wide.
3. Rice cultivation and fertilization: The plot should be applied with phosphate fertilizer before the farmland, 200-250 kg of farmyard fertilizer per mu, and 20 kg of urea.

Each time the water is changed is 1 in the amount of field water. /3 or so.
6. Began to arrest in late September.
