Abstract
Biological characters and the practice of dryland-raised long-age seeding associated with scattered-planting in rice, in contrast with dryland-raised middle-age seedling associated with scattered-planting, dryland-raised manual-planting, paddy-raised manual-planting were studied. The results were as follows: Its absorption of N,P,K and accumulations of dry matter were rich, while demonstrating the growth dominance of the early and middle stage, and the panicles and spikelets per unit area were richer, the root system was larger than those of the control, while its root activity was stronger, the ratio of root system at 0～7cm was larger, and root/shoot was higher, the light penetrating ratio of the middle and low part at the fullheading stage were higher, but its growth and development process was slower than that of the manual. Increasing N application at middle and later stage and hightening scattering density appropriately could amplify leaf area index, increase absorption of N,P,K and accumulation of dry matter, promote formation of more bearing panicles and improve yield. Increasing density, reducing the rate of N application at early growth stage and raising the rate of N application at middle and later growth stage were the suitable agronomic strategy for this kind of practice.
