According to the experimental results with two diffelent texture and fanning method, the influence of rice plough horizon
state is significant on the groWth and development of lice and soil's physical and chemical styles. Converting the conlnon
planting intO the mound planting,it increased the receiving areas of sun's radiant light and raised the soil tempelatule more than 1℃. Rice mound planting improved plough horizon's state such as water steam and heat accelerated the decomposition sped of soil organic matter benefited to soil readily available nutrient's release and supply, impeled developent of rice roots, leaded to tillering ready, first and more, advanced the heading stage and the date of futurity two or the days. The yield of fullow
drilling inecd 6-15%, compared to common planting but there is no signifunt d￣ce on rice yield among dmerent row spacing. It is restained and compensated among the yield factors such as available spike number, sac number per ear have boome the deCiding factors of yield per den. The analySis adultS of akin compound showed: in the first akin compound, the tendency of fullow drilling and common planting is coordinated. We improve pratical ed number an d sac yield through increasing tillering and available ear. In the secondary main compound, plant height is the biggest in narmw fullow drilling, ed number per ear is the biggest in wide fullow drilling and colon culture. In the thick main compound, the characteristic is thotisand kermal weight in fullow drilling and common culture.
