Prepare early to ensure that rice is transplanted on time

First, continue to strengthen the management of rice paddy field. Pay attention to the temperature control and reasonable ventilation management; then strictly control the watering. Pay special attention to the “give the fat fertilizer” 3-5 days before transplanting. The dosage is the same as that of the fertilizer. At the same time, spray the Lego or Kang broadband medicine and bring the fertilizer to the ground.

Second, to ensure the quality of paddy land preparation. Grab the field and turn the ground. Use the shallow water of the paddy leveling machine to lighten the water, the general squatting ground can be slightly deeper; turn the ground as far as possible, turn flat, turn over to 15 cm or more, pay attention to the pool reinforced. After the ground, the paddy field is required to be leveled, and the height difference is no more than one inch. Third, advocate the deep application of fertilizer in the paddy field. The best way to apply deep fertilizer is to apply it before the paddy field is turned over, not only to do the deep fertilizer application, but also to improve the fertilizer utilization rate. Fourth, the paddy field weeding should be flexible. For plots with severe grassland shortage or serious water leakage, the paddy field can be sealed; for most of the old paddy field, the grassland is not serious, and the method of weeding after one-time formula is adopted as much as possible to prevent the two drugs from causing phytotoxicity.

Axial Flow Pump

Permanent magnet synchronous motor axial flow pump is a new advanced application of permanent magnet synchronous motor in the field of pump. It has the characteristics of high efficiency, light weight, small volume (only 1 / 4 of the weight of traditional axial flow pump), large flow and convenient movement. Stepless speed regulation, head and flow can be adjusted by adjusting speed.

At the same time, another characteristic of permanent magnet synchronous motor is that the speed does not change with the grid voltage. When the voltage changes, especially when the voltage is low, it can still keep the head flow unchanged, which is not available in the traditional axial flow pump of asynchronous motor.
