In order to eliminate unfavorable factors and ensure that the current season does not affect the output and efficiency, the land after laser grader operations, especially for the first time using the laser grader, should adopt the following measures: 1. Settlement of the laser grader After that, the loose soil at the high point is scraped away, and the hard soil layer is exposed on the surface. If the method of using the tractor to configure the soil after still adopting the paddy field is adopted, this area will not be able to reach the mud depth required by agronomics. It is recommended to adopt the following two operations One of the methods is for soil preparation: Before the field is soaked, the land is rotated till it reaches the standard tillage depth, which provides a guarantee for the water to meet the agronomic requirements; 2 3 to 5 days after direct soaking, and then 254 Or medium-sized wheeled tractors such as 354 are used to suspend mixers to perform slurry mixing operations. Since this machine has a rotary tilling function, the mud depth after operation can meet agronomic requirements. 2. Compensated fertilizer According to the operation of the laser grader, please measure the initial data of the plot and mark the high point area of ​​the plot. Because some or all of the topsoil in this area is scraped away, the content of organic matter in the soil and fertilizers are greatly reduced, which may easily lead to low-yielding areas. The solution is to use PVC plates to divide these high-point areas into communities and apply more organic fertilizer as appropriate. And chemical fertilizers, and increase the frequency of topdressing appropriately. 3. The land after the operation of the laser grader with the laser grader is best harvested directly after the autumn harvest, and the bellflower will be thrown back to the field, and then fall to the ground, the depth of 15-18cm, in order to achieve fertilizer, increase production, efficiency purposes . 4. The land after zoning with a laser grader will generally not exceed 2cm in surface undulation. If the entire block is not partitioned or the partition is too large, the paddy field will fluctuate when the wind starts, causing rice seedlings to float and paddy rice. Lodging occurs during growth. Therefore, it should be divided into cells, generally 0.3-0.6hm as a cell. Partition pool vices best use PVC plate instead of soil terrier. PVC boards are easy to use, save time and labor, and generally have a service life of 3-5 years. The cost is only 120-150/hm. The PVC board can be rolled up at any time during various operations, and the operation can be inserted and buried again to provide convenience for large-scale mechanized operations such as machine insertion, harvesting, and tillage.
