The high yield...

From 1998 to 2000, fifteen hybrid mid season rice combinations were used to study the high yield physiology and cultural techniques of Ⅱ You 7 hao. Ⅱ You 7 hao, with a yield of 9000kg per hectare or more, share the following sink source characteristics: LAI 6 5~7 0 at full heating and 3 0~4 0 at maturation; biomass yield 18750kg per hectare at maturation; spikelet number over 37500 per hectare, and the ratio of leaf area to grain about 1 7cm 2 per grain. The high yield cultural techniques of Ⅱ You 7 hao are as the following: planting date at 3~4 leaves for rice seedlings, planting density in 24×10 4~27×10 4 hills per hectare,the number application of N in 165~180kg per hectare.

Suyu 76,a new table sweet potato variety was studied in this research. Suyu 303 being cultivated in the sweet potato production at present was used as the control. The high yield physiology and cultivation technology of Suyu 76 were studied by conventional methods of physiology and cultivation technology in the field of clay loam in Nanjing. Results demonstrated that the high yield physiologic characters of Suyu 76 were rapider growth, earlier tuber formation and higher net assimilation rate after planting, compared with Suyu 303 (CK). During the 50~90 days after planting, the dry matter accumulation of Suyu 76 was faster than that of Suyu 303. Studying on cultivation technology indicated that fertilizer had significant effect on the vine yield, biological yield, dry matter content of tubers and marketable tubers. But no significant effect had been found on other characters. The yields of vine and biology could be enhanced by increasing the amount of fertilizer applied. There were significant differences among effects of the plant densities on total tubers, marketable tubers and single tuber weight content. The higher plant density was, the more number of total tubers and marketable tubers was. There was a interaction of fertilizer and plant density on dry matter content of tubers in this experiment.

Cassava production is a new industry of which advantageous characteristic are good adaptability and high biological yield etc. Chinese cassava industry is confronted with tremendous opportunity and challenge after China joined WTO and Association of South-East Asian Nations (ASEAN). According to the investigation and research, the harvest area, yield, production, imports and exports trade of cassava were rapidly increased in the world since 5 years ago, and China imported the most cassava chip and tapioca in the world because of the domestic cassava manufacture demand exceeds supply. More over, new replaceable energy will be imperative under the situation that petrochemical energy resources are short in china. At present, cassava tapioca and auto-alcohol are better quality and economic efficiency than maize and sugarcane raw material. So, cassava commercialization has accelerated social and economical development in some South-China area now. At the same time,the problems of weak scientific research and extension, few adopted new cassava variety and technology, lack of industrial raw material, and behind technology of intensive processing and pollution-control etc. are slowing down the development of the commercialization of cassava. Naturally, the developing countermeasure of Chinese cassava commercialization will be getting more support from government, policy and finance, strengthening cassava research in breeding, high-yield physiology and biochemistry, intensive processing and pollution-control, enlarging cultivating area and spreading improved variety and technology etc.

木薯有适应性强和生物产量高等优点,是新兴的热带作物产业,自中国加入WTO和东盟“10+3”后,面临着巨大的机遇和挑战。经调研,近5年,世界木薯的收获面积、单产、总产和进出口贸易均增长较快,由于中国木薯产品远不能满足国内需求,迅速成为木薯干片和淀粉的最大进口国。此外,中国化石能源紧缺,发展替代能源势在必行。目前,用木薯加工淀粉和能源酒精,其品质和经济效益优过玉米和甘蔗等原料,较好促进华南地区的社会和经济发展。同时,存在木薯的科研推广基础差,良种良法面积少,加工原料缺口过半,深加工和治污技术滞后等困境。因此,中国木薯产业化的发展对策,就是加强政府、政策和资金的支持力度,强化木薯的选育种、高产生理生化、深加工和治污等研究,及大力扩种和普及良种良法等。
