Example Embodiment
[0063] Example 1:
[0064] The farmland is a rice-wheat rotation system. The system is arranged before transplanting during the rice season. The addition amount of biomass charcoal in the soil used to make the ridge is 1% of the dry soil weight; the length, width and height of the farmland biomass charcoal box 7 are respectively The thickness of the thick side of the wedge of the ditch biomass charcoal box 5 is 0.2 m, the width of the wedge is 0.7 m, and the length from the thick side to the thin side of the wedge is 0.6 m; the diameter of the buoyancy rod 15 is 0.2 m and the length is 0.5 m, 0.2 m and 0.4 m. It is 0.65 m; the partition 12 is 5 cm higher than the soil surface, so that the paddy field can maintain a 5 cm high water layer.
[0065] After the system is installed for the first time, base fertilizer is applied and rice is transplanted in a timely manner. The amount of fertilizer and the number and time of fertilizer application are the same as those of conventional fert...
Example Embodiment
[0072] Example 2:
[0073] The farmland is a double-cropping rice (two-cropping rice a year) system. The system is arranged before the spring-summer rice is transplanted. The amount of biomass charcoal added to the soil used to make the ridge is 1% of the dry soil weight; farmland biomass charcoal box The length, width and height of 7 are 0.5 m, 0.3 m, and 0.5 m respectively; the wedge-shaped ditch biomass charcoal box 5 has a thick side thickness of 0.3 m, a wedge width 1 m, and a wedge-shaped thick side to thin side length of 0.7 m; buoyancy The rod 15 has a diameter of 0.3 m and a length of 0.95 m; the partition 12 is 5 cm higher than the soil surface, so that the rice field can maintain a 5 cm high water layer.
[0074] After the system is installed for the first time, base fertilizer is applied and rice is transplanted in a timely manner. The amount of fertilizer and the number and time of fertilizer application are the same as those of conventional fertilizer management.

[0080] Example 3:
[0081] The farmland is a summer corn-winter wheat rotation system. The system is arranged before the start of the corn season, and whether to make ridges is determined according to the actual needs of the farmland. The addition amount of biomass charcoal in the soil used to make the ridges is 2% of the dry soil weight; farmland biomass charcoal The length, width and height of box 7 are 0.5 m, 0.2 m and 0.4 m respectively; the thick side thickness of the wedge-shaped ditch biomass charcoal box 5 is 0.2 m, the wedge width is 0.6 m, and the wedge-shaped thick side to thin side length is 0.6 m; The buoyancy rod has a diameter of 0.2 m and a length of 0.55 m; the partition is flush with the soil surface.
[0082] After the system is installed for the first time, base fertilizer is applied and corn is planted in a timely manner. The amount of fertilizer and the number and time of fertilizer application are the same as those of conventional fertilizer management.
