随着信息化、数字化时代的到来,人们对知识的获取量越来越庞大,在此背景之下,高校的图书馆管理工作开始引起社会各界的关注.图书馆作为支撑高校培养人才的重要基地之一,其地位和作用不言而喻,其中,图书管理员的素质对于图书馆建设发展起到至关重要的作用.当前,高校图书管理员普遍综合素质偏低,专业能力不能适应图书管理的需要,不能对高校的发展提供长久的支持.因此,提升图书管理员的素质成为高校应该重视的问题.
高校图书馆的图书典藏工作主要包括入藏图书资料调拨、配置以及剔旧等.在目前的图书馆藏工作中经常出现一些问题需要图书馆及时改进和优化图书典藏工作方法,以适应全开放模式下的读者需求.
To study the application effect of calcium fertilizer in garlic cropland in calcareous soil , a completely randomized block design of 5 treatments were set up with calcium sulfate ( gypsum ) amount of 0 (CK), 75, 150, 225 kg/hm2 and 300 kg/hm2 respectively.Then the growth period, bulb yield and single bulb weight of garlic were measured .The results showed that the application of calcium sulfate fertilizer made the seedling stage , scaly bud differentiation stage , stem elongation stage and bulb hypertrophy stage be 0~2 days in advance , while the maturation stage delayed 0~3 days.With the increase of fertilization amount , the resistance to diseases and insects had the trend from infection to lighter and then better resistance ; the single garlic bulb weight increased by 8.74%, 13.29%, 18.91% and 25.30% respectively compared to that of control, and the differences were highly significant; the yield increased by 8.73%, 13.27%, 18.90% and 25 .29%respectively , and the differences were highly significant .
枣疯病是由植原体引起的，是枣树生产中发生普遍、危害严重的侵染性病害。多点调查表明，枣疯病在河南省中牟县部分果园发生普遍，危害较重。在综防对策上，采取预防为主、综合防治的原则。重视科学建园、加强检疫、田间管理、病树治疗等多种措施的配套使用，同时还要注意传毒昆虫的防治。
Taking calcium sulfate as test materials,with garlic growth as research object,designs were set up on calcium sulfate(gypsum)for different fertilizer rate:75kg/hm2,150kg/hm2,225kg/hm2 and 300kg/hm2,with no calcium sulfate as control(CK),completely random block designs were applied on designs.The growth periods,garlic yield and weight of individual garlic bulb were measured,to study the application performance of calcium fertilizer in garlic cropland in calcareous soil.The results showed that the application of calcium sulfate fertilizer benefited garlic cultivation in many aspects:seedling stage,flowers phosphorus bud differentiation stage,stem elongation stage,and bulb hypertrophy stage were ahead of 0~2days,maturation stage delayed 0~3days,and resistance to disease and insects increased along with fertilizer rate,from infection to minor to resistant.Weight of individual bulb increased,compared with the control group,by 8.74%,13.29%,18.91%and 25.30%respectively,and the differences were significant;yield increased by 8.73%,13.27%,18.90%,25.29%respectively,and the differences were also significant.In conclusion,for garlic plantation in calcareous soil,application of calcium sulfate fertilizer could improve the performance of resistance to diseases and insects,and increase field production.
The systematic investigation of occurrence status of the economic crops root-knot nematode in Henan province were reported,and the identification of species of root-knot nematode was made.Through pot experiment,field plot experiment and field demonstration,a new type of plant-based insecticides on control of tobacco root-knot nematode were studied,the plant-based insecticides was a mixture consisting of Chinese Herbal Medicine Mixed.In order to provide scientific basis for developing low toxicity and low residual insecticide and guaranteeing the quality security of agricultural products.
