Management methods of full heading stage of Rice

Rice is the staple food in the south of China and one of the most important cash crops. It has a very wide planting area in our country. Dr. Yuan Longping even developed hybrid rice to solve the problem of food and clothing for nearly half of the people in our country. Rice cultivation has also been paid more and more attention, and how to manage it is the primary problem we have to solve, especially at the full heading stage. So how to manage it at full heading stage of rice? Let's take a look at it.

1. Rational irrigation

The filling stage comes after the full heading stage of rice, and the water demand during the filling period is very large, so we should strengthen irrigation and implement the principle of frequent application. It can not only enhance the permeability of soil, but also promote the growth and development of rice roots, improve the growth performance of leaves and increase the yield. The specific amount of watering is determined according to the growth and water content.

2. Clean up weeds

The weeds in the soil will compete with rice for nutrients and water, which hinders the growth and development of rice. Therefore, it is necessary to clean up the weeds in the field and around the ridges in time, and weed properly according to the growth of weeds at the full heading stage. It can not only enhance the growth of rice, but also facilitate the permeability of the field and promote the early maturity of rice.

3. topdressing at the right time

Full heading stage is the period when the growth of rice is accelerated, and rice is also prone to lodging at this time, so in order to inhibit the occurrence of this phenomenon and promote the saturation of rice grains. We should spray an appropriate amount of phosphorus and potassium fertilizer or foliar fertilizer at the full heading stage. It is helpful to reduce lodging and promote early maturity, increase yield and improve quality of rice.

4. Raise the water temperature

Rice is a high-temperature-loving crop, its growth rate will accelerate rapidly in summer, when it enters the full heading stage, it is also the most important time for rice growth. Therefore, we can appropriately increase the water temperature to promote the growth and early maturity of the water, and we can use plastic film to cover the irrigation system in the paddy field to increase the water temperature.

5. Prevention and control of diseases

In the full heading stage of rice, there is a high incidence of diseases and insect pests, such as rice blast, rice false smut and rice planthopper. Therefore, we should pay special attention to the prevention and control of diseases and insect pests, focusing on the prevention and control of plants with strong growth and full grains. The harm of diseases and insect pests will lead to a substantial reduction or even extinction of rice production, according to the different diseases and insect pests to make corresponding measures.

6. Prevent lodging

Lodging is the most common problem in the full heading stage of rice. Lodging will reduce the yield of rice and increase the empty shell rate of rice. We need to strengthen the fertilizer and water management of rice, we can spray calcium phosphate to slow down the growth rate of the bottom leaves and enhance the lodging resistance.

7. Greed for youth and premature senility

In the full heading stage, we should not only prevent greedy green late ripening, but also prevent the premature senescence of rice. Ethephon can be used to promote the growth of rice whose leaves are too tender but very large and the growth rate is slow. Premature senile rice can be enhanced by grain fertilizer and wet foliar fertilizer to prevent premature senescence.

The above points are the management methods at the full heading stage of rice, which is the most important period for rice growth. Without good management, the yield of rice will be greatly affected. Some growth regulators can be properly used to promote growth, increase grain weight and increase yield. That's all for today's introduction.
