Rice ear solar terms

The growth process of rice mainly includes seedling stage, tillering stage, heading stage and fruiting stage. The growth cycle of rice is related to the planting environment and the varieties selected. The growth cycle of some varieties is about 3-4 months, while others need 7-8 months. Rice planting area is relatively wide. The main producing areas are Yangtze River Basin, Pearl River Basin and Northeast China, and rice is a direct cash crop.

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

The growth cycle of rice is related to the planting environment and the varieties selected for planting. The growth cycle of some varieties is about 3-4 months, while others need 7-8 months.

Rice growth process

1. Seedling stage: First, select the rice seeds to be planted, and then sow them in the soil. When the conditions are right, the seeds will begin to germinate, which is the stage of seedling growth.

2. Tillering stage: When the seedlings reach a certain stage, they can be transplanted. The time from transplanting to jointing stage is called tillering stage. After transplanting, the roots of crops will be damaged, and it will take some time to recover, about 5-7 days.

3. Heading stage: It takes 30 days from rice jointing to young panicle growth, which is an important period for rice growth, and then slowly heading every 5-7 days.

4. Seed-setting period: After the ear of rice grows out, it is still dry inside. Generally, during the period from flowering to grain maturity, the stem will continue to grow after absorbing nutrients, and then blossom and bear fruit. This stage determines whether rice is high-yielding.

How to grow rice

1. Seed treatment: 2-3 days before sowing, rice seeds can be spread on the ground to dry. The day before sowing, remove the seeds with clear water, then bleach the full seeds with salt water, rinse them with clear water, and then dress them with selected seeds and phosphorus pesticides to prevent underground pests. After seed dressing, the seeds are piled up for 6- 12 hours and then sown.

2. Seedling management: When millet appeared in rice, it was found that the broken strips were serious. Soak the seeds in warm water, then mix the drugs to make the seeds suffocate and accelerate germination, and sow immediately after the seed coat turns white. When rice seedlings are slightly larger, they can be transplanted in fields with fewer plants. Generally, seedlings grow about 5 leaves, which is the easiest to survive.

3. Field management: When the rice is about 30 cm high, it can be applied once with intertillage, and it can be applied twice at booting stage, preferably during rainfall, so that fertilizer damage is not easy to occur. After jointing, deep ploughing of millet 15 cm or more can loosen soil, store more rainwater and promote deep rooting of new roots.
