At present, is it better for rice to use direct seeding than transplanting?

Summary: Which is better, direct seeding or transplanting, and which is more suitable for farmers?

My hometown is located in the Yellow River Basin. Although it is located in the north, due to the good irrigation conditions, rice will also be planted locally. However, most of the local rice is still planted by transplanting, and direct seeding is still rare. Scientific agriculture here thinks that if you don't want to take risks, it's best to plant rice by transplanting.

First of all, let's talk about direct seeding of rice.

Rice direct seeding is a rice planting method that omits the step of transplanting rice. In this way, rice direct seeding is more time-saving and labor-saving, which is very suitable for the current shortage of rural labor force. At present, direct seeding of rice can take two ways: artificial direct seeding and direct seeding.

Although direct seeding of rice is more convenient, there are more uncertain factors in direct seeding of rice. This is also a major factor that the yield of direct-seeded rice is not stable enough, so it is recommended to transplant rice if you do not want to take risks.

Since the uncertain factors in rice direct seeding are mentioned, here is a detailed discussion.

Rice direct seeding saves time and labor, and can reduce the damage to rice roots during rice transplanting. However, its shortcomings cannot be ignored.

First of all, direct seeding of rice shortens the growth period of rice, because direct seeding rice does not need the process of rice transplanting, and natural rice growth process does not need the process of rice seedling returning after transplanting, so planting time is generally later than transplanting time. The later sowing time will shorten the growth period of rice, which will affect the filling situation of rice. Naturally, it will also have a certain impact on the yield of rice.

The second is the emergence rate of direct-seeded rice, because direct seeding of rice is adopted, which is easy to cause rice seeds to be stolen by birds and mice, which will naturally cause uneven emergence.

The third is that there are too many weeds in rice direct seeding. The most troublesome problem for rice direct seeding is the problem of weeds in rice fields. Transplanted rice can solve this problem well. If the weed problem is not dealt with well at the seedling stage of rice, it will be more troublesome at the later stage.

Finally, the root system of direct-seeded rice is generally shallow, so the probability of lodging in the later stage will be greater.

Here is a brief look at the advantages and disadvantages of rice transplanting

Although rice transplanting is time-consuming and laborious, it is easy to cause damage to rice roots. However, transplanting rice can solve the problem of weeds in rice field well, which is more convenient for later field management, and the root system of rice is stronger, which is beneficial to increase the effective tiller of rice, and its lodging resistance is better than that of direct seeding rice.

In this way, there are more uncertain factors in the planting process of direct seeding rice. So there's more uncertainty about yield. Therefore, if you can do a good job in the late field management of direct-seeded rice, it can also be adopted. If you are not sure, transplant rice the old way.
