Rice is well divided, and the production is completed in half.

Increasing the tillering power of rice is a key measure for high-yield cultivation of rice, but only the early tillers are “effective tillers” before they can become panicles. Therefore, to improve rice production, we must not only work hard to promote the rice, but also work hard to promote the early rice. How to promote early rice tillering, multi-tillering, and increase effective ear?

1. Balance nutrition and apply nitrogen fertilizer

Nitrogen nutrition plays a leading role in rice tillering. Phosphorus nutrition plays an important role in promoting early tillering of rice. If rice is supplied in the tillering stage, if the supply of phosphate fertilizer is sufficient, the tillering will be earlier and more. Potassium fertilizer will enhance the resistance of rice and prevent the degradation of rice spikelets. Play an important role. Therefore, in order to increase the effective tillering of rice, it is necessary to adhere to balanced fertilization on the basis of ensuring the supply of nitrogen fertilizer, especially in the field of phosphorus and potassium deficiency. Phosphorus and potassium fertilizer should be added in the base fertilizer, and attention should be paid to early nitrogen fertilizer.

2, increase the application of promoted tiller

Increasing the tillering power of rice, especially improving the early low-level large tillers, is critical for the late-forming panicle rate and the large panicle. In order to promote the low-level big points, it is necessary to pay attention to the application of increased fertilizers. Here, it is recommended to use the rice and wheat-specific grand biological tillers to increase the yield of fertilizers - "蘖爆", "妙配", "Silicon" and "reinforcing elements". Shanda Bio's promoted split fertilizers are all uniquely formulated with a variety of medium and trace elements, and specially added potently promoted tillering factors, which promotes safe tillering and helps rice to achieve rapid greening. It can also replace paclobutrazol and safely and effectively control plant type. In the rice greening period (the live field is in the early stage of tillering), use the above-mentioned product 1 pack/mu and urea (10-15 kg) and mix and apply; if you can use the bottom fertilizer, you can use “蘖爆”, “妙配”, “Silicon” or “reinforcing element” is applied with large fertilizer and mixed.

3. Scientific water management

The higher temperature is conducive to the early emergence and tillering of rice in the early stage of seedling emergence. Therefore, rice should be as shallow as possible in the early stage of tillering, but it should not be cut off from water and drought. In the sunny day, the water layer can be kept about 3 cm in the field, except for the low temperature and rainy weather or the cold night.

4, timely and moderate drying field

Sun field can temporarily inhibit the growth of above-ground vegetative organs of rice, promote root canal, enhance root activity, and reduce ineffective tillering. It is very beneficial for cultivating large ears. It is necessary to grasp the good period and degree of the sun-baked field, which is generally suitable from the end of the tillering stage to the initial stage of the main stem and panicle differentiation, which is determined according to the number of seedlings in the field. The degree of drying the field depends on the seedlings, the seedlings, the leaves are thick, the long-lasting is to be exposed to the sun, and the sun is dry. For the soil with bad soil and deep mud, the field should be exposed to the sun, heavy sun, low field, cold soaked field, and the seedling should not be drained early, and the field should be lightly dried. The standard for drying the field is that the field side is cracked, the field is broken, and the person is not trapped. The standard for many times is to open the chicken claws.
