A new cylinder type forage cutter with high operation was designed and manufactured. Construction design and its performance parameters, helical angle of moving knife, setting height of fixed knife, overload protective device, throwing device and edge shape of fixed knife were analyzed. The results of test were as follows: optimal helical angle of moving knife was 20°, optimal setting height of the center of the cylinder above fixed knife was 20 mm, line speed of blower vane was 13.6m/s ,power consump...

通过对 93ZT - 5 0 0型滚筒式铡草机的设计研究，分析了滑切角、定刀配置高度、定刀刃角对铡草机性能的影响，并对机构设计进行了探讨，试验结果为：动刀的螺旋角为 2 0°；滚筒中心高于定刀 2 0mm ；抛送风机叶片线速度 13.6m/s ；开刃定刀比矩形定刀的功率消耗低 17.5 %；安全防护装置采用牙嵌式安全离合器；研究结果对滚筒式铡草机的设计和应用具有一定的参考价值

Under normal dosage (45g per acre), compared to the 12.5%NABU(187.5g per acre), the phytocidal activities of Tepraloxydim is about 3 or 4 times higher than it, phytocidal range and protecting effect are both better than it, too. Compared to the Gllant-s(10.8%), the speed and the effect are both outstanding, So there is a wide foreground for the appliance and extending of Tepraloxydim.

快捕净在田间正常用量(45克／公顷)下，与同类的12.5％拿捕净机油乳油187.5克／公顷的用量相比，杀草谱及防效都优于拿捕净，杀草活性比拿捕挣高3-4倍；与10.8％高效盖草能乳油相比，防治杂草的速度和药效也均有提高，因此，快捕挣的推广和应用具有比较广阔的前景。

Analysis result indicated that the exceptional-high concentrations of Mn was found to be the limiting factor for plant growth. The concentrations of Mn, Pb, and Cd in the ten plants and Mn-enrichmentalabilities of the ten plants were analyzed in this paper.Poa pratensts, Gnaphalinm affine, Pteris viltata L., and Phytolacca esculenta Van Houtte were proved to have good metal-enrichmental an...

结果表明，早熟禾、鼠麴草、蕨、和商陆对Mn有较强富集能力，同时也是Mn的耐性植物；早熟禾、鼠麴草以及蕨对Pb的吸收和富集能力较强；小飞蓬、早熟禾和麴草对Cd的富集能力较强；但是各种植物对这 3种重金属的富集能力均未达到超富集植物的要求，进一步的改良栽培实验仍在研究中

Vetiveria zizanioide is possesses strong depth roots and have better anchoring force and shear resistance; Vetiveria zizanioides is growed in ringent hinged joined concrete extending system,and its roots are interlaced and make foundation soil compound materals of soil and roots,but grass roots are considered three-dimensional reinforced materal and increase soil strength but also make for the stability of bank protection.

香根草具有纵深发达的根系系统，具有较高的锚固力和抗剪力。通过在开孔的铰链式混凝土块铺面系统中种植香根草，其根系在基土中盘根错节，使基础土体成为土与草根的复合材料，草根可视为三维加筋材料，使土体强度提高；更有利于护岸防冲系统的稳定。关键词：香根草，铰链式混凝土块，防冲护岸系统
