根茬粉碎还田机
1.
Technology optimization and test of the cutter of machine for chopping and returning stubble into soil by flame spraying and remelting NiWC alloy coating;
根茬粉碎还田机灭茬甩刀喷焊NiWC工艺优化
2.
In order to solve a problem that the Machine for Chopping and Returning Stubble into Soil high-priced and short- lifetime, wear-resistance coating was made on the substrate of 45# steel by flame spraying and remelting NiWC alloy.
为解决根茬粉碎还田机灭茬刀成本高、寿命短的问题,在45#钢制作的根茬还田刀具易磨损部位喷焊了NiWC合金抗磨涂层,通过正交试验和方差分析分析了试验因素对喷焊层耐磨性的影响程度大小依次为WC的含量、乙炔流量、预热温度和喷涂距离。
3.
In order to solve a problem that it is high-priced and lifetime short for the Machine for Chopping and Returning Stubble into Soil , abrasivewear resistance coating was made on the substrate of 65Mn steel by flame spraying and remelting NiWC alloy.
为解决根茬粉碎还田机灭茬刀成本高、寿命短的问题,在65Mn钢制作的根茬还田刀具易磨损部位喷焊了NiWC合金抗磨涂层,磨损试验表明,喷焊NiWC合金灭茬刀的相对耐磨系数比65Mn钢淬火回火处理的有较大程度的提高。
3) straw stubble returning machinery
秸秆根茬切碎还田机
1.
In order to solve the problem of high-priced and short-lifetime of straw stubble returning machinery, the Ni60 and NiWC coatings were prepared on the surface of 45# steel specimens by flame spray welding.
为解决秸秆根茬切碎还田机鞭式刀具成本高、寿命短的问题,在45#钢基体上制备了火焰喷焊Ni60和NiWC喷焊层。
5) corn stubble
玉米根茬
1.
During cultural course, soil humus content of treatment with stubbles was highre than ck, increased extent of corn stubbles was 0.
在整个培养过程中，根茬处理的土壤腐殖质含量均高于对照，提高幅度玉米根茬为００５６％～０１１５％，大豆根茬为００５２％～００９５％，且松结态腐殖质的净增加量（玉米根茬为００２４％～００３７％，大豆根茬为００１０％～００２４％）远大于稳结态腐殖质的净增加量（玉米根茬为０００６％～００２１％，大豆根茬为０００３％～００１３％），而玉米根茬又好于大豆根茬。
补充资料：玉米根长法
分子式：
CAS号：
性质：利用药剂浓度与玉米根长抑制程度成正比的原理，测定除草剂活性的生物测定方法。适用于一些磺酰脲类除草剂的测定。将配制不同浓度的待测除草剂毒土，放人塑料杯内。选择胚根长3mm的玉米种子播入杯内，每杯5～6粒，再覆盖表土，均匀滴入适量水，在25℃恒温培养3～5天，测定玉米苗主根长度，计算抑制率和IC50。
