The latest measures to solve the problem of excessive tillering of rice

Rice tillering is the most critical period in the growth process of rice, which is directly related to rice yield. However, if rice tillering is too much, it will lead to too high rice density, affect large panicles, lead to disease and insect pests and lodging. So what about rice tillers? Let's get to know each other.

1. Drainage and sunning

If it is found that rice tillers are too many, first of all, drainage and sunning in time can not only effectively control ineffective tillers, but also promote the development of rice roots, which is conducive to the absorption of nutrients and lodging resistance in the later stage. The standard of sun-drying field is that the leaves are slightly yellow, and the ascites should be timely after sun-drying, and the water layer should be kept at 3-5 cm, which can effectively promote effective tillering.

2. Reasonable topdressing

Excessive or partial application of nitrogen fertilizer will lead to a large number of ineffective tillers in rice. Therefore, nitrogen fertilizer should be used as little as possible or not at jointing and booting stage, and potassium fertilizer should be used as the main topdressing, which can promote stem thickening and facilitate the formation of large panicles. The topdressing time should also be grasped well, generally 15-20 days before heading of young rice, about 15 kg potassium chloride per mu should be applied.

3. Weeding

Weeding is best carried out at the 2-4 leaf stage of rice. If the weeds in the field are not removed in time, the normal growth of rice will be affected. In addition to the reduction of rice tillers, diseases and insect pests may be aggravated, especially some germs parasitized on weeds, and normal large-area infection. And once the tillering stage produces disease, it will also lead to abnormal tillering, so weeding is very important.

4. Pest control

Too much tillering of rice will reduce the permeability of the field, lead to closed field and cause some diseases and insect pests, so we should do a good job in the prevention and control of diseases and insect pests, especially for sheath blight, rice planthopper, borer and so on.
