Yuzhong City, Sichuan Province has been listed by the Ministry of Agriculture as one of the 51 county-level cities (cities) for the demonstration and promotion of rice planting and mechanization technology. This year, mechanical planting and transplanting has basically ended. In this year's demonstration and extension work, several issues and solutions that should be noted have been summarized and are for reference only. I. Problems 1, seedling emergence is not uniform. The four demonstration sites in the city selected winter paddy fields for raising seedlings, mainly using floppy disks and a small amount of hard disks, strictly following the technology of breeding and standardizing procedures, and adopting dry valley, swollen valley, and bud valley to raise seedlings respectively. The seedlings were found to be uneven on the fifth to tenth days after nursery. , different shades and uneven thickness. 2, after the machine inserted more seedlings. After the machine was plugged, the farmers responded with more broken seedlings, mainly due to incomplete seedling emergence, then excessive fertilization, rapid growth of seedlings, uneven thickness of stalks, and excessive length of medlar leaves. 3. After the machine is inserted, there are many missing nests, and the farmer's supplementary planting workload is large. The main reason is that seedlings are not sown artificially, and they are caused by two cold spells before and after the Ching Ming Festival. 4, nursery time is not allowed. The city’s nursery time began on March 27 and planted rice seedlings from April 28 to May 18, and finally planted for more than 40 days. Second, the solution 1, emergence is not uniform. After comparing with last year's and this year's drought and childbearing, observation and analysis, we should choose the dry field seedlings, moisture management effect is better. 2, after the machine inserted more seedlings. The "dwarf, strong, uniform" seedlings should be bred in strict accordance with the specifications for mechanical breeding and transplanting. 3. After the machine is inserted, there are many missing nests. In order to raise the seedlings, the following three levels should be strictly controlled: one is to select the seed and to remove grains that do not germinate or germinate. The second is the sowing of crops. Generally, the seeding amount is determined by a boring machine. The seeding rate must be divided into three to four times. The first time is 50%, the second time is 30%, and the third time is 20%. Press 10% each time. The third is prevention and pest control, to prevent dead seedlings. 4, grasp the time of seedlings. It is appropriate to push the seedlings from January to January to ensure that the seedlings are no longer than 40 days old. It is better to avoid the cold wave period before and after Ching Ming Festival each year. HEBEI PINGLE FLOUR MACHINERY GROUP CO., LTD , https://www.plrollermill.com
