Rice is very sensitive to herbicides at booting stage. Don't use herbicides randomly.

The long heading stage of rice should be the booting stage of rice. Booting stage is the key period of rice growth, so how to manage rice at this time is very important.

Characteristics of Rice Booting Stage

The booting stage of rice is important because it is not only in the critical stage of vegetative growth but also in the stage of reproductive growth. At this time, rice should not only protect roots but also promote leaf growth. And it is necessary to prevent premature senescence of rice.

How to manage rice booting stage?

The first thing to say is the fertilization problem at booting stage. The fertilizer needed at booting stage is the period when the most fertilizer is needed at rice growth stage. In addition to the need for topdressing, it is also necessary to pay attention to the time of topdressing. Too early in time is easy to cause the increase of ineffective tillers of rice, and too late in fertilization will cause the occurrence of green rice, excessive growth and easy lodging.

Fertilization at booting stage needs to consider many factors, including land conditions, weather conditions, rice growth conditions, etc. Generally, the most suitable fertilization time is about two weeks before rice heading. Generally, about 8 kg of compound fertilizer should be applied to rice fields, but if the rice in rice fields is growing well, the amount of fertilizer can be reduced. It is usually combined with rice field irrigation for topdressing. Be careful not to break the fallen plants of rice when fertilizing.

The second is the water problem. During this period, the rice not only needs topdressing, but also needs a lot of water. Therefore, the field cannot be cut off. It is best to keep deep irrigation water to protect rice seedlings and prevent rice development from being affected by drought in rice fields. In addition, attention should be paid to the fact that after deep irrigation of rice fields, the soil of rice fields is relatively soft, and lodging of rice should be prevented.

The third thing to pay attention to is that the rice growth during this period is relatively sensitive, so it is best to carry out weeding manually or mechanically, do not spray herbicides, which will cause poor rice bearing.

The fourth is to do a good job in the prevention and control of diseases and insect pests. During this period of time, the weather is hot and rain increases, so rice is more prone to diseases. This period of time prone to rice bacterial blight, rice blast, rice stem borer, sticky insects and other diseases and insect problems. Flexible response to different pest problems.
