目前,大型农业机械发动机多为四个缸和六个缸,四个缸的工作顺序多为1-3-4-2,六个缸的多为1-5-3-6-2—4。在实际工作中,有的驾驶员认为气缸数和工作顺序一样,气门(间隙)可调整顺序就一样,这是不对的。如有两台六个缸的发动机,其工作顺序一样,就因进、 相似文献

The irrigation system in The Fayoum is designed for a continuous supply of water (24 h a day, 7 days a week) to rotational units, which vary in size from about 20 to 500 fe. The Fayoum Irrigation Department is responsible for the delivery of irrigation water to the rotational units. Within the units, the farmers rotate the water in a seven days rotation.One of the characteristics of present water management of The Fayoum is the non-uniformity of the division of flow over the main canals. The purpose of this paper is: (i) to study the effects of this non-uniformity by comparing water management in tertiary units in an area with a (more than) sufficient water supply to an area subject to some water shortage; (ii) to discuss implications of the present tertiary unit water management for the water management of the entire The Fayoum.The findings are that: (i) the non-uniformity of the main system water supply has a strong effect on the water management in the tertiary units. Water shortage results in a lower cropping intensity and fallow land, no possibility to cultivate rice, and a possible trend towards salinization in the Seila area; (ii) the farmers in both research areas modify the official rotation schedule. These modifications create a high flexibility in the rotational units: The water supply for different crops and plots is adjusted almost to the minute.Glossary and abbreviations Bahar

中国沙棘育种研究进展 总被引：6，自引：2，他引：4
黄铨 《国际沙棘研究与开发》2006,4(4):25-29
近20年来,中国的沙棘育种,以“多目标育种、多层次选择、选引育并进、有性与无性繁殖兼用”和“多生态区布点、多单位协作”的理念作指导,开展了多方面的工作。通过对种群的系统调查和种源试验,查明了中国沙棘的种群构成与变异规律;在中国沙棘基础上,通过多层次选择,选育出“红霞”、“无刺雄”等5个沙棘良种;在引进种质基础上,通过多种类型的实生选种,选育出“棕丘”、“无刺丰”等15个无性系品种;经多种组合的杂交试验,确知“蒙古沙棘×中国沙棘”的F1代,有显著的杂种优势,并筛选出理想的亲本组合,应用于杂交种子园的营建;在以不同亲本所作的杂交子代群体中,选育出“华林1号”、“天水1号”等杂种无性系品种。到20世纪末,对所选育的各类沙棘良种和主要引进品种,分项进行了区域化试验,多数品种已批量的应用于生产。目前,中国的沙棘育种,正在前期选育无枝刺,大果粒、高产、适应性强的总体目标和育种成果的基础上,进一步追求各类营养保健物质的高含量和高品质。研究手段也将向多元化发展。 相似文献

Three trickle irrigation schedules, two of which were scheduled according to soil water potential ( soil) (tensiometer method) and daily stem contraction (DSC) (dendrometer method) respectively and the other one was a schedule of restricted water supply, were applied to a mature peach orchard.The annual water application based on soil was greater than that based on DSC. However, tree growth, fruit size and leaf water potential (leaf) on the trees in the dendrometer scheduling plot did not differ from those in the tensiometer scheduling plot while the premature fruit drop and fruit bud initiation were greatly different. The restricted water supply treatment limited significantly both tree and fruit growth. In addition, the lower leaf was observed on the trees in this plot.Further study shows that use of the dendrometer method for scheduling irrigation satisfies the water needs of the plant and that the tensiometer method is less accurate.Abbreviations leaf

教师的"讲"与"问"是需要的,特别是在关键处,教师的精讲、精问往往起了画龙点睛、恍然大悟的导向作用。主体也不是否定教师的主导作用,或放弃教师的责任,实行"大放手、大撒手"的"放羊式"教学。强调学生的主体作用是指教师要"以生为本",发挥学生的主观能动性,来促其发展。 相似文献

This paper describes the changes introduced in water users' associations in the Province of Mendoza, Argentina. Before 1985 there were 709 water users' associations, known as Canal Inspection, each of them in charge of the administration of an area of about 300 ha, corresponding to tertiary and quaternary canals. At present there are 21 reorganized inspections administering an average area of 6 000 ha. The democratic system for the election of authorities is described and the method of budget preparation and control is discussed. The advantage of reorganization is illustrated through the economic assessment of the Reduccion Main Canal. This canal irrigates an area of 13 985 ha. The annual benefits due to reorganization are estimated to total A 32 800 (US$ 41 000), being 2.1 times the annual budget of the Inspection. 相似文献
