What are the four growth cycles of rice and what is the average yield per mu?

The growth of rice goes through four stages: seedling stage, tillering stage, heading stage and fruiting stage. Taking tillering stage as an example, seedlings can be transplanted after growing for a period of time, and the stage from transplanting to jointing is called tillering stage. After transplanting, the root system of rice will be damaged and it will take some time to recover. Usually, it takes about 5-7 days for the aboveground part to recover.

1. What are the four growth cycles of rice?

1, seedling stage

First, select the rice seeds to be planted, and then sow them in the soil. Under suitable conditions, seeds will begin to germinate, which is the seedling stage. Generally, before the leaves of seedlings grow out, the nutrients grown in the soil are mainly absorbed through the roots. After the leaves grow, they can be converted into nutrients through the light absorption of the leaves.

2. Tillering stage

Generally, seedlings can be transplanted after growing for a period of time, and the stage from transplanting to jointing stage is called tillering stage. After transplanting, the roots of crops will be damaged. At this time, the rice needs to rest for a period of time, about 5-7 days, and the aboveground part of the rice can be restored.

3. Title date

It takes a month for rice to grow from jointing to young panicle, which is the key to rice growth. Ears will be pulled out slowly, with an interval of about 5-7 days.

4. Fruiting period

After the ears of rice were pulled out, they all faded because they were not strong. Generally, during the period from flowering to grain maturity, the stem will start to grow and rise, and then blossom and bear fruit. This stage determines whether rice can obtain high yield.

2. What is the average yield per mu of rice?

1, the yield per mu of rice will not always be fixed at a certain value, but will be affected by factors such as season, variety, region and management. Generally, the yield per mu of low-yield fields is about 600-700 kg, and that of high-yield fields is about 1000- 1200 kg.

2. The fruit of rice is rice, which is also called brown rice after hulling. Brown rice can be obtained by grinding off the rice bran layer. About half of the world's population lives on rice. In addition to being edible, rice can also be used as wine, sugar and industrial raw materials.

3. The main rice producing areas in China are Yangtze River Basin, Pearl River Basin and Northeast China. Rice is a direct cash crop and almost the staple food of China residents. The rice planting area in China is 245 million mu, and the hybrid rice planting area is 200 million mu.
