Effect of different transplanting periods on the growth and yield of high-quality hybrid rice in the system of rice intensification

The effects of different transplanting periods on the growth and yield of high-quality hybrid rice in the system of rice intensification(SRI) are studied in this paper. The results show that the early transplantation of the rice seedling can improve the numbers of the tiller at lower position and then prompt the formation of big spike. The combination of this technique with rarely planting method can produce more tillers and more available spikes and achieve the aim of high yield. The experiment proves that the system of rice intensification saves not only the rice seeds but also labors.
