一种适合稻区紫云英生产实际的紫云英加工调制方式

将紫云英鲜草分离为草汁、细渣、纤维状渣；以粉状能量精料为载体吸收汁液；3种制品都以晾晒的方式进行干燥。晾晒时，3种制品综合占场面积较原草减少近90％；3种制品均可在一个晴日内风干，比原草干燥速度提高一倍余；细渣品质与国标一级苜蓿草粉相当；“二次拌汁料”、“三次拌汁料”之粗蛋白、粗纤维含量符合生长肥育猪饲养标准；加工方式切合稻区紫云英生产实际及产区综合条件，有推广价值，且易推广。     

Development of Chinese Near-isogenic Line of Rice and Their Differentiating Ability of Pathogenic Races of Blast Fungus

The rice( Oryza L. ) variety, Lijiangxintuanheigu(LTH), is a universally susceptible variety. A set of near-isogenic lines (NILs) of rice which has single resistance gene for each line was developed by use of LTH as recurrent parent and Kusabue,Tsuyuake, K1, PiNo. 4, K60 and BL1, which are from Kiyosawa‘s differential varieties(KDV), as donor parents. Differentiating ability of these NILs to Philippine isolates was compared with that of their donor parents, KDV and IRRI‘ s NILs. The results of comparative studies were as follows: (1) Differentiating ability of Chinese NILs to Philippine isolates was much stronger than that of their donor parents and that of KDV. (2) Chinese NILs had similar ability to differentiate races to IRRI‘s NILs or higher differentiating ability than them. But IRRI‘s NILs almost had no differentiating ability to isolates from japonica rice-growing regions. They can not be used to differentiate races of isolates from japonica ricegrowing regions. Whereas, Chinese NILs can be used to differentiate races of isolates from both japonica ricegrowing regions and indica rice-growing regions. It was concluded that the set of Chinese NILs can be used as international differentials.     

中国矮马运铁蛋白遗传多态性的初步研究

采用聚丙烯酰胺凝胶电泳对中国矮马运铁蛋白多态性进行了测定。在运铁蛋白位点共发现5种表型，即F2F2，DF2，F2H2，F2O和F2R，由Tf^D,Tf^F2,Tf^F2,Tf^H2,Tf^O和Tf^R等5个等位基因控制，其基因频率分别为0.0312,0.7188,0.0625,0.0312和0.1563；基因的杂合度（H），个体鉴别概率（Dp)和亲仔关系排除概率（PE）分别为0.4530,0.6875和0.2586。     

特优175高产结构分析和配套栽培技术探讨

特优175分蘖力中强、穗大粒重、株型理想、高产稳产.经调查分析,其高产结构中,以每穗结实粒数的变异(cv=17.20%)最大,与产量相关最密切(r=0.591 1**,对产量的通径(p=1.035 6)和净贡献率(pr=0.612 1)最大;其次为有效穗(cv=10.40%,p=0.709 5,r=0.184 4,pr=0.130 8);千粒重是品种的稳定性状,对产量的贡献有限.每公顷产量7 500 kg左右的适宜产量结构为:每公顷250万穗,每穗结实120粒、千粒重28 g左右.在保持一定的穗数下,较高的每穗结实粒数是高产栽培的主攻重点.配套栽培技术是:(1)适时播种,培育壮秧;(2)适时移栽,合理密植(每公顷基本苗150～180万);(3)合理调控水肥,每公顷施纯氮150～180 kg,氧化钾120～160 kg,五氧化二磷60～80 kg;(4)综合防治病虫害.

Analysis on Mineral Element Contents in Associated with Varietal Type in Core Collection of Yunnan Rice

Eight-element contents of 653 unpolished rice samples harvested from Xingping experiment farm, Yunnan Province under the same ecological conditions were analyzed by ICP-AES method. The mineral elements content were closely related to low diversity, high-yielding, and multi-resistance breeding; The K, Mg, Ca and Mn content in high-yielding and resistant varieties were high, and other nutrients such as P, Fe, Zn and Cu were low, which was connected with the heredity and physiological mechanism of mineral nutrients. There is zonal distribution of mineral elements content from Yunnan rice, especially for P, Fe, Zn and Cu co-related with the diversity center, paddy versus upland, glutinous and non-glutinous, glume-hair versus nuda, rice color, rice flavor, soft rice versus non-soft rice, but it did not find any association with indica-japonica types. The results supported the ecological variety group view of 5-grade taxonomic system “species-subspecies-ecological groups-ecological variety groups - varietal types“ .
