不同播种方法对水稻秧苗素质及其产量的影响
Effects of Different Sowing Methods on Seedling Quality and Yield of Rice
摘要
Abstract
In order to explore the suitable sowing method for strong,long -age and dry nursery seedlings of rice to raise yield,the field trials were conducted with Lindao 16 as material.Three treatments were de-signed,including T1 (irrigating pre -sowing water → sowing seeds → covering 1.0 cm of soil once → cover-ing film),T2 (irrigating pre -sowing water → sowing seeds → covering 3.5 cm of soil twice → retaining 1.0 cm of soil before seedling emerging),T3 (sowing seeds → covering 1.5 cm of soil once → irrigating fully). Randomized block design with three replications was used according to the seedbed.The results showed that the seedling quality of T1 treatment was the best and its yield was the highest with the average tiller number per plant of 1.42,root number of 44.6,fresh weight per hundred seedlings of 259.5 g and yield of 10 459.2 kg/hm2 .The seedling quality and yield of T3 treatment was the second,and its average tiller number per plant was 0.89,the root number was 37.2,the fresh weight per hundred seedlings was 224.8 g and the yield was 9 178.7 kg/hm2 .The seedling quality of T2 treatment was the worst and its yield was the lowest with the average tiller number per plant of 0.75,root number of 35.5,fresh weight per hundred seedlings of 219.1 g and yield of 8 495.2 kg/hm2 .There were very significant differences among three treatments.In conclusion, the method of irrigating pre -sowing water → sowing seeds → covering 1.0 cm of soil once → covering film could raise temperature,keep water,prevent birds,improve the emergence rate and the seedlings were strong so that they could grow early and quickly after transplanting thus adding the number of grains per spike and spikes per unit area and raising the yield.关键词
