Talking about the Deficiency of Rice No-tillage Casting

Rice no-tillage and seedling transplanting is a new rice cultivation technique promoted in recent years, which can play a role in reducing production costs, increasing economic benefits and maintaining water and soil, and reducing loss, and has an active role in rice production. However, there are also limitations and inapplicability of no-tillage and throwing. Here, I combine my own production practices and conclusions to talk about some experiences of rice no-tillage and transplanting techniques. First, no-tillage dumping is mainly to save the cost of farming, rather than increase production. The cost of rice cultivation varies greatly from place to place. There are significant differences in the Shagang area of ​​Kaiping City. Some villages spend more than 300 yuan per year per acre (two forgings), and some villages only charge 200 yuan for 200 yuan. According to the calculation, the cost per acre to eradicate grass will be reduced by 20 to 30 yuan, and no-tillage and seedling planting will save 170 to 180 yuan, which is equivalent to an increase of nearly 200 kilograms in production. The benefit is considerable. In the past, it was reported that rice no-tillage seedlings could increase production. The main reason for this is to increase production through appropriate management of fertilizers and water. Strictly speaking, under the same conditions of fertilizer and water management, no-tillage dumplings generally have a 3% to 5% reduction in output, and individual production will reach flat production. Second, the fields with good drainage and irrigation conditions are suitable for no-tillage and hoeing. Because the no-tillage and field-casting fields need to return water and drain water in time after the chemical treatment, the fields with poor drainage and irrigation conditions are not suitable for no-tillage and throwing. 3. In some cases, the workload of no-tillage and dumping is slightly greater. Since the previous draft was not rotted at the time of casting, there were a few fallen on the head of the manuscript. In order to avoid stuck conditions, some peasants had to throw in the fields one by one to reduce the phenomenon of stuck. In the early days of Daejeon, low temperature and rain are not suitable for no-tillage. Early-planting individual years will experience low temperature and rainy weather after planting. If they are carried out under such weather conditions, no-tillage and seedling planting will cause the planting plant to fail to take root for a long time, resulting in severe stagnation and eventually leading to The production dropped significantly. Early last year, it created low temperature and rain, and it began to take root one week or so after it was thrown. Even worse, the original plots with more weeds had to take 9-10 days to take root, causing severe stagnation, resulting in insufficient seedlings and weaker seedlings. , Miao Feng greatly delayed. When the production of rice production dropped significantly, the yield was generally reduced by 10% to 15%; the original weeds were relatively large, and the production of land with harder roots was reduced by about 20%. This shows that low-temperature and rainy weather should not be no-tillage, especially if the original weeds are more affected. 5. No-tillage and seedling throwing for many consecutive years may make soil compaction. No-till farming for many years in a row will make soil consolidation merely an inference, because I have not done this experiment. Although no-tillage rice throwing in rice has the above-mentioned incompatibility and limitations, it has the advantage of reducing the cost of farming. As long as we can use it correctly in practice and seek advantages and avoid disadvantages, the economic benefits are still very obvious, especially in places where there are a lot of people, and where the cost of farming is high.
