Brown rice milled to remove the rice bran.
layer to get rice.
The growth type of rice refers to rice tillering.
There are three types of relationship between the termination stage (jointing stage) and the beginning of panicle differentiation period.
Overlapping type: panicle differentiation precedes jointing, that is, the tillering has not yet terminated and the panicle begins to differentiate, and the tillering stage partially overlaps with the long panicle. It is a subtype of double cropping rice cultivated in triple cropping or early maturing medium rice.
Articulation: Panicle differentiation and jointing are basically carried out at the same time, that is, panicle differentiation begins at the end of tillering, that is, the tillering stage and the long spike stage are connected. There are medium-ripening varieties with 5 elongated joints in the aboveground part, and the production is combined with promotion and control. Most of them are late-maturing medium rice and early-maturing late rice.
Separation type: jointing precedes panicle differentiation, and panicle differentiation begins 10 15 days after tillering termination, that is, the tillering stage and the long spike stage are separated. The aboveground part with 6 or more elongation nodes belongs to this type.
Because it has long vegetative growth, it should be cultivated to control the early growth to ensure safe maturity. Most of the late-maturing late rice is a subtype.
Growing environment. Rice likes high temperature, humidity and short daylight, and the requirements for soil are not strict, but paddy soil is the best. The minimum temperature of seedling germination is 10 12, and the optimal temperature is 28 32.
The average daily temperature of tillering stage is more than 20, and the appropriate temperature of panicle differentiation is about 30. Low temperature prolongs the differentiation of branches and spikelets. Heading temperature 25 35. The optimal temperature for flowering is about 30, below 20 or above 40, and pollination is seriously affected.
