【Abstract】 Using Gengyou-653, Liaoxing-21, Liaogeng-1708, Liaogeng-985, Liao-1720 and Jiadao-31 as test materials, the growth stage traits, main yield structure and measured yield of rice cultivated in direct seeding were investigated, and the suitable varieties of direct seeding rice were selected for planting in Liaoning Province. The results showed that Liaoxing-21 and Liao-1720were suitable for dry direct water tube planting, and the yield reached the average value of 613.92ab(kg/667 m~2) and 570.70ab(kg/667 m~2). It can be used as drought direct seeding in central Liaoning rice area.更多还原
