The growth period of single-season late rice and mid-season is longer. The growth period of Honda varies greatly depending on the variety, generally 90-120 days. The temperature in the early season of the single-season late rice and mid-season rice is higher than that of the early rice, and later than that of the double-season late rice, and there is sufficient growth and development time, especially the vegetative growth period. Therefore, there are obvious stages of tillering, jointing, long thick, and long spikes.
The relationship between vegetative growth and reproductive growth: single-season late rice is isolated and medium-sized rice is connected. Therefore, there are two distinct peak periods of fattening, one occurs in the tillering stage and the other in the young panicle differentiation stage, and the peak of late absorption is higher than that in the previous stage, indicating that the panicle fertilizer of single-season late rice and mid-season is more important. According to the Yunnan Academy of Agricultural Sciences, based on the application of 1000 kg of manure per acre of rice, the NPK fertilizers were compared according to the previous two methods: the number of panicles per unit area and the number of flowers. After the less law is higher than before and after the heavy method, but the real grain number, 1000 grain weight and yield are lower than before and after the heavy method.
