鸡(土从)菌生活史的研究

通过孢子分离,小白球分离都在人工合成培养基上萌发成菌丝,形成小白球,证实小白球是鸡(土从)菌生活循环中的一个发育阶段.鸡(土从)菌担孢子萌发的单核菌丝,经过锁状联合发育成双核菌丝,继而形成小白球,但难以在培养基上长出子实体,而在蚁巢上合轴交叉的菌丝交织成小白球,再发育成原基,在适宜的环境条件下鸡(土从)菌破土而出形成子实体.本研究从无性循环及有性循环两方面初步阐明了鸡(土从)菌的生活史.     

猪伪狂犬病油乳剂灭活疫苗的制备及安全性与免疫性试验

用本室分离鉴定的猪伪狂犬病毒鄂A经毒株接种仓鼠肾细胞（BHK－21）,制备病毒抗原液，毒价不低于10^-6TCID50/0.1ml。经一定浓度的甲醛溶液灭活后与油相佐剂乳化研制成油乳剂灭活油疫苗4批。本研究对该制品的安全性、免疫性进行了测定。对18g左右小白鼠接种0.3ml，初生仔猪、断奶仔猪及妊娠母猪加倍剂量注射，均未出现不良反应，安全性良好。对母猪的繁殖性能不产生影响。后备母猪及妊娠母清中和抗体指数于免疫后21d达到316以上，间隔35d加强免疫一次后，中和抗体指数可达1000以上。断奶仔猪及初生仔猪免疫后对强毒的攻击，保护率分别为100％及90.62％。     

寒地高效日光节能温室建造技术

黑龙江省地处北纬43°～53°以北高寒地区,过去由于冬季温度低,日照时间短,能源消耗大,冬季均以加温温室为主,随着市场经济和新一轮菜蓝子工程建设的发展,黑龙江省高效日光节能温室面积已近2000hm2(公顷),在冬春季节蔬菜生产中发挥着重要作用.     

微生物有机肥在小白菜上应用研究

研究了微生物有机肥对白菜生长发育、产量、品质等方面的影响，结果表明：小白菜施用微生物有机肥能提高小白菜根系活力，促进菜秧早期生长，提高小白菜品质；维生素C含量明显增加，但其肥效不如化肥迅速，中后期产量较低，因此，在优质蔬菜栽培时，应提倡施用有机肥为主适当配施少量复合肥的施肥方法。

Carbon sinks in mangroves and their implications to carbon budget of tropical coastal ecosystems

Nearly 50% of terrigenous materials delivered to the world's oceans are delivered through just twenty-one major river systems. These river-dominated coastal margins (including estuarine and shelf ecosystems) are thus important both to the regional enhancement of productivity and to the global flux of C that is observed in land-margin ecosystems. The tropical regions of the biosphere are the most biogeochemically active coastal regions and represent potentially important sinks of C in the biosphere. Rates of net primary productivity and biomass accumulation depend on a combination of global factors such as latitude and local factors such as hydrology. The global storage of C in mangrove biomass is estimated at 4.03 Pg C; and 70% of this C occurs in coastal margins from 0° to 10° latitude. The average rate of wood production is 12.08 Mg ha^?1 yr^?1, which is equivalent to a global estimate of 0.16 Pg C/yr stored in mangrove biomass. Together with carbon accumulation in mangrove sediments (0.02 Pg C/yr), the net ecosystem production in mangroves is about 0.18 Pg C/yr. Global estimates of export from coastal wetlands is about 0.08 Pg C/yr compared to input of 0.36 Pg C/yr from rivers to coastal ecosystems. Total allochthonous input of 0.44 Pg C/yr is lower than in situ production of 6.65 Pg C/yr. The trophic condition of coastal ecosystems depends on the fate of this total supply of 7.09 Pg C/yr as either contributing to system respiration, or becoming permanently stored in sediments. Accumulation of carbon in coastal sediments is only 0.41 Pg C/yr; about 6% of the total input. The NEP of coastal wetlands also contribute to the C sink of coastal margins, but the source of this C is part of the terrestrial C exchange with the atmosphere. Accumulation of C in wood and sediments of coastal wetlands is 0.205 Pg C/yr, half the estimate for sequestering of C in coastal sediments. Burial of C in shelf sediments is probably underestimated, particularly in tropical river-dominated coastal margins. Better estimates of these two C sinks in the tropics, coastal wetlands and shelf sediments, is needed to better understand the contribution of coastal ecosystems to the global carbon budget.     

常见儿科病红细胞免疫粘附功能检测的临床意义

检测儿科常见疾病患者中的红细胞免疫粘附功能发现：（１）新生儿的红细胞免疫粘附功能尚未发育完善，低于正常儿童水平；（２）急性肾炎患儿的红细胞免疫粘附功能呈现继发性增强；（３）肾病综合征、风湿性疾病、大叶性肺炎、秋季腹泻及急性白血病等患儿的红细胞免疫粘附功能呈继发性降低；（４）红细胞免疫粘附功能的变化与疾病的发展及转归有关。提示在儿科疾病的诊断和治疗中观察患儿的红细胞免疫粘附功能有重要意义。     

热胁迫对辣椒花粉发育及其生活力的影晌

用光学和荧光显微镜及扫描电镜观察等方法，研究了热胁迫对辣椒花粉形成发育、生活力、萌发率及雌性系统的影响。发现辣椒不同耐热性品种在高温胁迫下，花粉、花药发育过程出现异常，花粉生活力、体外萌发率下降，花粉管生长延迟，正在生长的花粉管伸长停滞。这些影响感热性品种比耐热性品种表现更为明显。在雌性系统中未见明显影响。
