When do rice plants mature in Sichuan? An introduction to the maturity time

As a superpower in rice cultivation, our country is very experienced in this regard. Today, let's start with Sichuan and talk about when rice plants mature in Sichuan. Let's take a look!

1. When do rice plants mature in Sichuan

The maturity time of rice in Sichuan is generally concentrated in August to September each year. The specific maturity time needs to be confirmed according to the rainfall, sunlight, cultivation environment and variety of that year.

2. Characteristics of rice cultivation

1. Rice likes high temperatures, humidity and short-day conditions. It does not require strict soil conditions, but paddy soil is the best. The minimum temperature for seedling germination is 10-12°C, the optimum temperature is 28-32°C, the average daily tillering stage is above 20°C, and the suitable temperature for panicle differentiation is around 30°C. Low temperatures prolong the differentiation of branches and spikelets.

2. The optimum temperature for heading is 25-35°C, and the optimum temperature for flowering is about 30°C. Below 20°C or above 40°C seriously affects pollination. The relative humidity should be 50-90%. From panicle differentiation to the peak of grain filling is the key stage for grain setting. A population with balanced nutrition and high light efficiency is of great significance for improving the seed-setting rate and grain weight.

3. During the heading and grain-filling stages, a large amount of water and mineral nutrients are needed, and at the same time the vigor and functional period of the stems, leaves and root system should be strengthened. About 500 to 800 kg of water is needed per kg of rice.
