Correctly understanding the method of rotation in paddy fields has a great influence on the growth of rice and the improvement of agricultural machinery work efficiency. Therefore, the water field rotary target operation should master the following points: First, the appropriate amount of water should generally be controlled in the field before the rotation of the turtle 2 to 4 hours into the water, water depth of 6 to 8 cm. For plowed fields, the depth of submergence is appropriate to the depth of the puddle. Second, the coulter to install flat ridge operations, the coulter elbow installed outward; fill the ditch operation, boring tool elbow installed inward; generally cultivator, plow month elbow mixed installation. In order to reduce the direct contact of the stalk weeds with the coulter shaft, when the coulter shaft is equipped with the left and right two coulters, the two bolts are lengthened by about 10 centimeters to eliminate the phenomenon of cooperating the shaft of the coulter. Third, the target speed of the rotation of the unplowed plate field for the first time, the tractor to use slow two sweep forward, the coulter shaft to select the low speed is appropriate; rotary tillage two and three times plowed paddy fields. Tractor can choose slow three speed operation speed. Plow) High speed can be used. 4. The locomotive is walking along the diagonal line of the field to the left or to the right. A loquat starts to grow till it gradually expands outwards, and finally it can wind around the field and make a circle. This method has high work efficiency, low oil consumption and good quality. 5. The number of farmland passes the agronomic requirements for rice planting. Casting rice field. General 耙2-3 is the best; artificially planting fields is better. 6. Please mark the places where the ponds and ditches are filled with bamboo rafts before slipping. Once slipped, you can take a piling and self-rescue approach, that is, hit a wooden stake about 5 meters in front of the locomotive. Fasten the wire rope to the wooden post and the other end to the drive wheel. Hang the gear, shake the handle and crank the crankshaft to walk the tractor. The tractor is pulled out of the pit by a wire rope wound around the drive wheel.
