28.7%精甲霜灵?咯菌腈?噻虫嗪FS防治甘蔗凤梨病田间药效评价

为筛选甘蔗凤梨病防治药剂,寻求最佳使用技术方法,结合新植蔗下种,采用蔗种单芽包衣、双芽包衣、双芽浸种等3种方式对28.7%精甲霜灵·咯菌腈·噻虫嗪FS防治甘蔗凤梨病效果进行田间评价。结果表明,28.7%精甲霜灵·咯菌腈·噻虫嗪FS蔗种双芽包衣和双芽浸种2种处理都能有效防治甘蔗凤梨病。28.7%精甲霜灵·咯菌腈·噻虫嗪FS 942~1605 mL/hm2蔗种双芽包衣防效为58.69%~61.20%、28.7%精甲霜灵·咯菌腈·噻虫嗪FS 1000~1500倍液蔗种双芽浸种处理防效为51.51%~54.70%,明显优于对照农药50%多菌灵WP,且对甘蔗安全。甘蔗凤梨病高发区,可结合当地甘蔗生产实际,于甘蔗下种期,采用28.7%精甲霜灵·咯菌腈·噻虫嗪FS防治甘蔗凤梨病,蔗种包衣处理剂量以942 mL/hm2为宜,蔗种浸种处理药液浓度以1500倍为宜。     

2种不同种衣剂对玉米‘黑糯100’生长状况和抗氧化防御系统的影响

本研究通过田间试验,选择噻虫嗪和噻虫嗪-苯醚甲环唑混剂2种内吸性农药作为玉米种衣剂,探究了种衣剂对玉米乳熟期果穗鲜重,不同生长时期各部位鲜重的影响,以及对玉米植株抗氧化防御系统的影响。结果表明：以推荐使用剂量（6 mL/kg种子）,种衣剂对玉米植株各部位鲜重的影响主要在玉米苗期和拔节期,相比对照处理,噻虫嗪和噻虫嗪-苯醚甲环唑混剂处理明显降低玉米苗期和拔节期各部位鲜重,乳熟期时3个处理之间差异不显著;施用种衣剂能增加果穗鲜重,但增加效果不明显。种衣剂处理均促进植株叶绿素的合成,且噻虫嗪和苯醚甲环唑混施较单施噻虫嗪玉米叶绿素含量更高。单施噻虫嗪和噻虫嗪与苯醚甲环唑混合施用均会引起玉米叶片中抗氧化酶SOD、CAT和POD活性的提高,使叶片GSH和MDA含量降低,说明在本试验施用的种衣剂剂量胁迫环境下,玉米叶片抗氧化防御系统可作出应答,调节细胞的代谢过程,使玉米植株正常生长。

不同种衣剂对红芸豆根腐病防治效果研究

为了筛选出对红芸豆生长安全且防治根腐病效果理想的种衣剂,首先采用室内盆栽试验,研究种衣剂处理对红芸豆生长的安全性,再通过田间药效试验筛选防效较高的种衣剂。盆栽试验结果表明：9个处理对红芸豆出苗率无显著性影响,但各处理对其初期生长有不同影响,60g/L戊唑醇悬浮种衣剂（flowable concentrate for seed coating,FSC）+600g/L吡虫啉FSC处理对红芸豆平均株高、根长、苗鲜重、苗干重均具有显著抑制作用;35%多·福·克FSC处理对苗干重有一定增加作用,但对平均株高、根长、苗鲜重均无显著性影响。大田试验结果表明,11%精甲·咯·嘧菌+27%苯醚·咯·噻虫FSC、18%噻灵·咯·精甲FSC、12%甲·嘧·甲霜灵+600g/L吡虫啉FSC和62.5g/L精甲·咯菌腈+600g/L吡虫啉FSC 4个处理播种后30d的防治效果显著高于35%多·福·克FSC处理,防效分别是80.04%、73.77%、63.46%、57.25%;其余3个处理防治效果较低,与35%多·福·克FSC处理差异不显著。与空白对照相比,35%多·福·克FSC处理增产率最高,为30.18%,12%甲·嘧·甲霜灵+600g/L吡虫啉FSC处理增产率最低,为12.57%,二者差异显著;其他6个处理增产幅度虽低于35%多·福·克FSC处理,高于12%甲·嘧·甲霜灵FSC+600g/L吡虫啉FSC处理,但与二者差异均不显著。综合室内安全性评价、防治效果、增产效果,11%精甲·咯·嘧菌+27%苯醚·咯·噻虫FSC、18%噻灵·咯·精甲FSC具有较好的应用前景,适合在生产中与其他防治措施综合应用。     

六种不同药剂对小麦纹枯病防治效果的研究

本试验通过对市场上 6 种药剂对纹枯病防治效果的观察发现:小麦返青拔节期施用 250 g/L 丙环唑乳油、75%肟菌·戊唑醇 悬浮剂、240 g/L 噻呋酰胺悬浮剂 SC、25%苯甲·丙环唑水乳剂四种药剂 24d 均能降低小麦纹枯病茎率,对小麦纹枯病有一定的预防作用。药剂施用 49d 时,25%苯甲·丙环唑水乳剂、75%肟菌·戊唑醇悬浮剂、噻呋酰胺·氟环唑能够降低纹枯病病情指数;三种药剂处理的病情指数病均低于 21%且病指防效在 5%以上。药剂施用 78d 时,各处理的病茎率均 96%以上,且与对照差异不显著;各处理与对照病情指数均在 30%左右,仅有噻呋酰胺·氟环唑处理的病指防效相对较好为 3.32%。各处理产量与对照无显著差异。     

油菜的生长发育和醣、氮及脂肪代谢特点的初步研究

氮肥水平对强筋小麦产量和氮素利用的影响

为明确强筋小麦产量与效率相协同的最优施氮量,试验选用‘济麦20’和‘洲元9369’ 2个优质强筋小麦品种为试验材料,设置0、120、180、240、300 kg N/hm ²等5个施氮水平,用烘干法和凯氏定氮法分别测定小麦成熟期干物质量积累和含氮量,用以计算小麦氮素积累及氮素利用相关指标。结果表明,随氮肥投入量的增加,小麦产量呈现先升高后降低的变化趋势,其中‘济麦20’在N180和N240下达最高产量7.28 t/hm ²和7.26 t/hm ²,其较高的产量主要源于相对平衡的产量构成因素以及较高的干物质积累量（平均18.54 t/hm ²）;‘洲元9369’在N180下产量最高达7.75 t/hm ²,其较高的产量主要源于较高的单位面积穗数(970.65万/hm ²)、穗粒数（30.83粒）、较高的干物质积累量(20.77 t/hm ²)和收获指数(37.33%)。虽然氮肥偏生产力随着氮肥施用量的增加逐渐下降,但两品种的氮肥回收效率、氮肥农学利用率和氮肥生理利用效率均可在N180条件下达到最高值,其中,‘济麦20’最高值分别为62.67%、5.71 kg/kg、9.11 kg/kg,‘洲元9369’的最高值分别为63.65%、7.33 kg/kg、11.55 kg/kg。综合产量水平和氮素利用相关指标,本区域强筋小麦生产中产量与氮素利用效率相协同的施氮量为180 kg/hm ²。

Sensitivity of Corn, Oats, Peanuts, Rice, Rye, Sorghum, Soybean and Tobacco to UV-B Radiation under Growth Chamber Conditions

Sensitivity of different agronomic crops to UV-B radiation was studied under environmentally controlled conditions. UV-B radiation reduced plant height, fresh weight, dry weight and ash contents. The reduction varied among the different species tested. Narrow-leaved plants (mainly C₄) were less sensitive to UV-B than broad-leaved plants (mainly C₃).     

Resources,representation, and authority in Jharkhand,India

Abstract: Jharkhand is at the centre of India's struggles to define ‘the environment’ and ‘economically relevant natural resources’. Although cultural labels are applied by leaders who seek influence in these struggles as well as by many of those people who listen, an ethnonational analytic frame does not help answer the questions: How, why and when has the political idea of environment changed in India? When and why has the Jharkhand movement chosen violent tactics? When and why has the Jharkhand statehood movement realised electoral success? Or, why was Jharkhand state formed? To address such questions, a long range historical‐institutional approach is much more fruitful.

The origin,evolution, cultivation,dissemination, and diversification of Asian and African rices

Summary Available evidences drawn from biosystematics, evolutionary biology, biogeography, archaeology, history, anthropology, paleo-geology and paleo-meteorology are pooled to reconstruct the series of events that led to the cosmopolitan cultivation of the Asian cultivated rice (O. sativa) and the regionalized planting of the African cultigen (O. glaberrima) in West Africa. The genus Oryza originated in the Gondwanaland continents and, following the fracture of the supercontinent, became widely distributed in the humid tropics of Africa, South America, South and Southeast Asia, and Oceania. The two cultivated species have had a common progenitor in the distant past. Parallel and independent evolutionary processes occurred in Africa and in Asia, following the sequence of: wild perennialwild annualcultivated annual. The weed races also contributed to the differentiation of the cultivated annuals. The corresponding members of the above series are O. longistaminata Chev. et Roehr., O. barthii A. Chev., O. glaberrima Steud., and the stapfii forms of O. glaberrima in Africa; O. rufipogon Griff., O. nivara Sharma et Shastry, O. sativa L., and the spontanea forms of O. sativa in Asia.The differentiation and diversification of the annuals in South Asia were accelerated by marked climatic changes following the last glacial age, dispersal of plants over latitude or altitude, human selection, and manipulation of the cultural environment.Cultivation of rice began in many parts of South and Southeast Asia, probably first in Ancient India. Cultural techniques such as puddling and transplanting were first developed in north and central China and later transmitted to Southeast Asia. Wetland culture preceded dryland culture in China, but in hilly areas of Southeast Asia, dryland cultivation is older than lowland culture. The planting method progressed from shifting cultivation to direct sowing in permanent fields, then to transplanting in bunded fields.Widespread dispersal of the Asian cultigen led to the formation of three eco-geographic races (Indica. Sinica or Japonica, and Javanica) and distinct cultural types in monsoon Asia (upland, lowland, and deep water). Varietal types changed readily within the span of a millenium, largely due to cultivators' preferences, socio-religious traditions, and population pressure. Genetic differentiation developed parallel to the ecologic diversification process.The African cultigen developed later than the Asian cultigen and has undergone less diversification. The wild races in South America and Oceania retain their primitive features mainly due to lack of cultivation pressure or dispersal.Both the African and Asian rices are still undergoing evolutionary changes at habitats where the wild, weed, and cultivated races co-exist.
