Fourteen experiments,using the methods of soil culture, sand culture and field plot culture etc.,were carried out in the last three years (1981-1983). The chief characters of the plant Sesbania cannabina Pets, such as plant height, stem and leaf yield, nodule dry weight,nodule number and N2-fixation activity of root-nodule per plant etc.,were lower under flood culture condition than under upland culture condition with soil moisture holding capacity contrary to the former statement that Sesbania cannabina Pe... 经过三年用土培、砂培、田间小区等方式做了十四批试验。得出淹水栽培的田菁在株高、茎叶产量、根瘤数量与重量、株瘤固氮总活性等主要性状上均劣于土壤水分状况为田间持水量的旱栽的结论。并找到了其必然性的原因。否定了田菁淹水栽培优于旱栽的说法。 田菁与土壤水分关系的生长曲线是以田间持水量为顶点的三次抛物线型。有别于前人以其他豆科作物作出的二次抛物线型。田菁耐淹力强于耐旱力。缺水(低于田间持水量的60％)的危害比水分过多(淹水)严重。生产中常出现淹水优于旱栽的现象,是两害相较轻为优的反映。在灌溉设施不完善的情况下,生产中实行淹水栽培还是可取的。 文摘来源 In the fall of 1978, a new variety, early rice 78130 was bred by crossing Shan You 2 with V20 through careful choice of four generations in succession. The entire growth period of the variety is 125-130 days in spring planting and 115 days in ''Dao Zhong Chun" ( i.e.summer planting with the seeds of spring planting ) . This variety of rice has fifteen main stalks per seedling. Its plant form is similar to that of Shan You 2, but its sword-leaves are short and straight. Its total efficient ears per mu ( 1/15... 1978年秋,用汕优2号与威20杂交,经连续四代选择高结实率优良株系,育成了新品种78130。此品种主茎15叶,早季全生育期125～130天,倒种春115天;株态近似汕优2号,但剑叶短直;每亩有效穗20～25万,每穗60～80粒,结实率稳定90％以上,千粒重27～28克,亩产400～450公斤,高产可上500公斤;耐寒又耐淹,抽穗扬花期对风雨适应性好;高抗稻瘟病,兼抗白叶枯病和稻曲病;后期根叶不早衰,谷粒饱满;适应性广;米质中上。1983～1985三年累计全省推广约260万亩。若每亩以最低增产量25公斤计算,全省可增粮6500万公斤以上;包括粮食增产,种子加价和节省防病工本,其社会效益可达2000万元。经福建省农作物品种审定委员会审定,列为全省推广早稻良种之一。1986年早季,全省种植面积可达250万亩以上。 文摘来源 During 1980-1984, two hundred and ninetyeight strains of rice bacterial leaf blight (Xanthomonas campestris pv oryzae) were collected from 56 counties and were tested for pathogenicity in Fujian. According to the intensity of virulence, they were divided into four groups: I . II . III and IV, while 298 strains were inoculated onb differential varieties of rice. So far the reactions between pathogen and host showed that the quantitative differences were attended. No specificity was found. The tendency of str... 1980～1984年共测福建省56县稻白叶枯病298菌株,据其致病力强弱划分为四个菌系群(Ⅰ—Ⅳ)。菌株和品种间的关系存在着数量级差异,尚未发现有明显的特异性反应,其分布特点有沿海强、山区弱的趋势。用Ⅱ—Ⅳ菌系群的13个菌株测定国内外部份水稻品种抗性,有15个品种表现强的抗病性。我省早、晚稻当家品种都为感病或中感品种。74—105品种表现高抗、耐淹,适宜在沿江沿海低洼易淹稻田推广种植。杂交稻威优6号、威优30、四优30为较好抗病组合,已在全省推广应用。 文摘来源 << 更多相关文摘
