Correctly understanding the method of rotation in the paddy field has a great influence on the growth of rice and the improvement of agricultural machinery work efficiency. Therefore, the following points should be mastered in the field of rotary drilling in paddy fields:
1. Amount of water: too much water, the field is not easy to pulp, can not meet the quality requirements; too little water, the field is not easy to flatten, but also increase the friction resistance of agricultural machinery in the soil. therefore. Generally should be in the field 2 hours -4 hours before the rotation, the time into a good water depth of 6 cm to 8 cm.
2. Coulter installation: According to the surface condition of the soil, the direction of the installation of the elbow of the rotary plough machine is determined, the flat ridge operation is performed, and the coulter elbow outwards is installed; the ditch operation is performed and the coulter elbow is installed inward. Leaking out the left and right two coulters of the coulter shaft, lengthen the two bolts by about 10 centimeters to eliminate the phenomenon of cooperating the shaft of the coulter.
3. Spinning speed: The forward speed of the walking tractor and the rotation speed of the coulter shaft should be determined according to the specific conditions. For the first time in the unplowed wheat straw field, the tractor can choose to use the slow second gear, the coulter shaft can choose the low speed is appropriate; Rotary tillage second, three times and plowed paddy field, tractor can choose Slow third gear speed, the coulter shaft can use high speed.
4. Walking direction: Many operators use the tactics to make the formation of heavy laps in Tianbian, which takes time and fuel. The correct direction should be used for the slanting method, that is, the locomotive should start cultivating along the diagonal line of the field to the left or right, and gradually expand outwards, and finally it can wind around the field one circle. This method has high work efficiency, low fuel consumption and good quality.
5. Putian times: According to the agronomic requirements of rice planting, throwing paddy fields, generally 2 to 3 times the best, artificially planted fields, to 2 times better. If too many fields occur in the field, it will damage the structure of the soil pellets and cause soil compaction. At the same time, it will accelerate the wear and fuel consumption of farm machinery and equipment. Unevenness will occur in the fields and the number of passes will not meet the agronomic requirements.
6. Please be careful not to trap: Use bamboo rafts before the operation to make marks on the sides of the pond and ditch. Once slipped, you can take measures to help yourself. That is, a wooden stake is placed about 5 meters in front of the locomotive, the wire rope is tied to the stake, and the other end is hung on the driving wheel. Hanging gear, crank handle cranking crankshaft, so that the tractor walks. The tractor is pulled out of the pit by a wire rope wound around the drive wheel. In addition, it can also be pulled out by cultivators or tractors with higher power.
