Why must rice be transplanted? Is the live broadcast not good?

Although direct seeding of rice saves time and effort, it also has many shortcomings. Direct seeding of rice can't avoid bad weather, and its ability to resist disasters is weak. Early rice seedlings rot and die, and late rice is prone to cold dew wind, which easily leads to large-scale production reduction. There are many kinds of herbicides and pesticides used in direct seeding of rice, which have great influence on agricultural ecological environment. In addition, direct seeding rice has shallow root system and high population density, which is easy to cause yield reduction due to lodging. Therefore, although direct seeding of rice is relatively easy in the early stage, it takes more effort to manage it in the later stage than transplanting rice seedlings. Therefore, in general, if we want to produce high-yield or high-quality rice, there is still a lot of room for improvement in direct seeding technology. Welcome to communicate.
