摘要: 本文报导了1962-63年在马里共和国利用稻宿根苗进行生产栽培试验结果。供试品种:冈比亚卡和"督克风兰"。宿根稻初试产量即分别达到3168公斤/公顷,3492公斤/顷,已显著超过当地一般水稻单产水平,为充分利用当地丰富土地资源,发展水稻生产,降低成本,提高劳动效率开辟了新途径。查明了稻宿根苗萌发自基最高分蘖节至地表下分蘖之间的节上休眠等,其生态生理发育阶段近似种子胚芽;宿根苗比种子苗根系强大、叶色浓绿、长势旺、分蘖力分蘖势强、成穗率高、穗大穗匀。文章讨论了宿根稻与再生稻的异同性及宿根苗经济性状的优异表现对水稻科学理论与实践发展的应有启示。

Abstract: In this paper the result of a study on rice cultivation with perennial root sprouts was repouted. The study was made in Mali in 1962-1963 with two rice cultivars "Gambiaka Kokoum" and "Doc-Phung-Lun". The yieid of perenniai root rice of the two cultivars was 3168 kg/ha and 3492 kg/ha, resdectively, which exceeded significantly the general yield per unit area in locality. the study had opened up a new way to make ruli use of the local aboundant nture resouvces of cultiyable lanol for oeveloping rice production, reducing production costs and raising working efficience. In the study it was found that the young sprouts of perennial root rice originated from resting buds of tillering node between the highest and the under-ground tillering nodes. The ecophysiological deveiopental stages of the resting buds were observed to be similar to the seed's plumules. The rice plants from perenial roots exhibited superiority to seedling in root system, growing and tillering power, rate of prosuctive panicle., and appeared darker green foliage, and produced bigger and uniformer panicies than those of seedling. The difference and the relationship between the perennial root rice and the ratooning rice, and the use of perennial root rice in the studies on scienctific theory and producing practice of rice were discussed in this paper.
