How did rice seedlings come from?

The bought rice seeds germinated and grew taller.

Raising seedlings in rice fields has always been a traditional way of raising seedlings in rural areas. In Guangxi, sowing is generally around Tomb-Sweeping Day and planting is around May Day. Therefore, there are some differences between early rice and late rice in the cultivation of seedling fields. If there is green manure in the early rice seedling field, it should be ploughed and harrowed ten and a half days before seed soaking to complete the green manure retting. The second ploughing time is the day of soaking seeds.

Growing environment of rice:

Rice likes high temperature, high humidity and short sunshine, and has low requirements for soil, but paddy soil is the best. The lowest temperature of seedling germination is 10 ~ 12℃, and the optimum temperature is 28 ~ 32℃. The average daily temperature at tillering stage is above 20℃, and the optimum temperature for ear differentiation is around 30℃. Low temperature prolonged the differentiation of branches and glumes. The optimum heading temperature is 25 ~ 35℃. The optimum flowering temperature is about 30℃, lower than 20℃ or higher than 40℃, and pollination is seriously affected.

The relative humidity is 50 ~ 90%. The key period of fruiting is from panicle differentiation to full filling stage; The population with balanced nutritional status and high photosynthetic efficiency is of great significance to improve seed setting rate and grain weight. A lot of water and mineral nutrients are needed at heading and fruiting stage; At the same time, it is necessary to enhance the root activity and prolong the functional period of stems and leaves. It takes about 500 ~ 800 kg of water to form 1 kg of rice.
