Effects of Different Seedling Raising Methods on Seedling Quality and Yield of Rice
摘要
Abstract
To investigate the effects of an integrated high-efficiency technology combining a novel seedling-raising sub-strate material with dark-induced germination acceleration on seedling quality,a field experiment was conducted in Tian-zhu County,a national demonstration area for large-scale grain production promotion.Using the rice variety Yixi-angyou2115 as the material,four treatments were established:dark-induced germination acceleration+specialized sub-strate sheet for seedling raising(T1),conventional treatment+specialized substrate sheet(T2),dark-induced germination acceleration+traditional substrate(T3),and conventional treatment+traditional substrate(T4).The effects of different seedling-raising methods on emergence rate,seedling survival rate,seedling quality,and yield of rice were comparatively analyzed.The results showed that T1(dark-induced germination acceleration+specialized substrate sheet)exhibited the highest emergence rate(92.5%)and seedling survival rate(87.6%),which were 6.9%and 7.4%higher than those of T4,re-spectively.Regarding seedling quality,T1 was significantly superior to the other treatments in terms of seedling height,to-tal root number,stem diameter,and white root number.In terms of yield,T1 achieved the highest actual yield,reaching 877.6 kg/667 m2,which was 9.2%higher than that of T4.Dark-induced germination acceleration significantly improved seed germination uniformity and root activity,while the specialized substrate sheet outperformed the traditional substrate in water and nutrient retention as well as aeration.In conclusion,'dark-induced germination acceleration+specialized substrate sheet'was the optimal seedling-raising combination under the conditions of this experiment,capable of achiev-ing the goals of robust seedlings and high yield,and is suitable for promotion and application in mechanized seedling rais-ing and transplanting production.关键词
