摘要
1997～1999年在福建省龙海市研究粮食超高产栽培,明确:①粮食一年三熟超高产的最佳作物组合是稻-稻-马铃薯,平均产量达27050±190.5kg/hm^2;②超高产水稻的形态生理特性是穗多穗大,具有巨大的库容量;根系形态发达,活力高而持久;NPK养分积累优势在前期和中期,干物质和贮藏性碳水化合物(SC)的积累优势在中期和后期.根据研究结果,提出粮食三熟起高产栽培技术的构想,拟于今后验证完善.
Super high yield cultivation was studied at Longhai, Fujian province during 1997 to 1999. The results were as following :(1)The best combination of annual three crops system was rice-rice-potato,which average yield was 27050+ 190. 5kg/hm2;(2)The morphological physiology characters of super high yield rice were sufficient panicle number, large sink size, flourishing root morphology, high and enduring root vigor. The superiority of NPK accumulation was during early and middle stages. However,the superiority of dry matter and storage carbohydrate accumulation was in the middle and late stages. According to the studies,the concepts of annual three crops system with super high yield cultivation technique were proposed,and will be identified and perfected in the future.
