What are the precautions during the young panicle differentiation stage of rice?

Rice cultivation is very common in China; in rural households, almost every family has a certain area of paddy field. Rice cultivation in China has a history of several thousand years. Although the cultivation techniques are relatively mature, cases of cultivation failure still occur. That is mainly because the surrounding environment was not well controlled during the young panicle differentiation of rice. So what do we need to pay attention to during young panicle differentiation? Let's take a look together below!

1. Light

Light is closely related to the growth of rice, especially during the young panicle differentiation stage of rice. Failure to ensure sufficient light will affect the differentiation of the young panicle to a certain degree, or even cause it to fail. We cannot control the timing of young panicle differentiation, but we can adjust the environment. If it is during cloudy and rainy weather with no light, we should supplement light in time. Also, the seedlings should not be closed in too early, otherwise the field will become closed and lightless, causing young panicle differentiation to fail, and the development of branch nodes and spikelets will also be affected, with abortion in severe cases.

2. Temperature

Each stage of rice growth has different temperature requirements. The most suitable temperature for young panicle differentiation is around 27 degrees, but because the temperature varies greatly between day and night, the temperature should be controlled at 30-35 degrees during the day, and at night it should be at least ten degrees lower. Only in this way can young panicle differentiation be more favorable. The lowest temperature that can be tolerated during the young panicle differentiation stage must not be lower than 15 degrees. Cell division requires a higher temperature, and the temperature for rice panicle development can reach above 40 degrees. Only by ensuring suitable temperature can the normal growth of rice be guaranteed.

3. Water

Everyone knows that rice cultivation requires a large amount of water, especially during the young panicle differentiation stage. The water demand at this stage is the greatest of the entire growth period of rice. The water demand at this period can require the field moisture content to reach 90%. If there is not enough water supplied for growth in the paddy field, the development of young panicle spikelets will be hindered. However, the amount of water should not be too much either. Too much will affect root respiration, affect nutrient absorption, and cause rice panicles to become deformed and rice grains to be empty, affecting yield.

4. Nutrition

During the young panicle differentiation stage, many new branches and leaves will continue to grow, and the nutrients required will gradually increase accordingly. This stage is formally one of the peak periods of fertilizer demand for rice. Topdressing should be carried out in time to promote flower bud formation and spikelet differentiation. This is what we often call flower-promoting fertilizer. Then, about a week before the heading stage, apply fertilizer again to prevent spikelet abortion and promote plant growth. This is flower-preserving fertilizer. This period is when rice absorbs nutrients fastest and, of course, also consumes them fastest, so there must be enough fertilizer to ensure the nutrients needed for growth.

The young panicle differentiation stage is equivalent to the infancy period of us humans. It requires careful care to prevent harm and ensure the healthy growth of the infant. The principle is the same. If management work is not done well, it will have a great impact on both the yield and quality of rice. So everyone should pay attention to observing more, and solve problems when they are found, so as to better increase yield. That is all for today's introduction.
