Is it better to transplant rice or sow?

Each has its advantages and disadvantages, according to local conditions.

First look at the advantages and disadvantages of direct seeding:

Direct seeding is generally only used in the south, because the temperature in the south is relatively high and will not affect rice germination. But in the northeast, when rice is planted in April and May, the water in the rice fields is still frozen. If direct seeding is used, the seeds will freeze to death, so people will raise seedlings in the greenhouse first and then transplant them when the weather is warm. Because the paddy fields in the northeast are relatively wide, the mechanization of planting rice is very developed now, which is generally mechanical planting, and only the corners are artificially transplanted.

Advantages and disadvantages of rice cultivation and transplanting

Paddy fields in the south are relatively small, so it is impossible to sow seeds by machine. Spreading seeds directly in farmland can reduce labor. Nowadays, many rural people in their prime will choose to work in cities, but how many women, old people and children stay in the countryside, sowing is much faster than transplanting rice seedlings, and the high temperature in the south will not affect rice germination.

But direct sowing still has many disadvantages. If you want to sow directly in the rice field, it will be about half a month earlier than normal seedling sowing. During this half a month, it is easy to freeze the seeds in late spring. Secondly, although direct seeding is earlier than seedling raising, it grows slowly, which is likely to reduce the quality and yield of rice. Finally, weeds are easy to appear in direct seeding, and the rice planted in direct seeding should be weeded several times in the later stage.

Therefore, although live broadcast saves time and effort, there are also many problems in the later stage, especially weeding. Therefore, direct seeding will not be the development direction of rice planting in the future, but machine transplanting will be the main direction of rice planting in the future. Mechanical transplanting has many advantages, such as reducing labor force, improving efficiency, improving lodging resistance of rice and reducing the occurrence of diseases and pests.
