A 1.8 kb fragment of 3' terminus of the viral RNA was amplified by RT PCR, cloned and its sequence was determined. Sequence comparisons showed that it shared 71.5%～99.1% homology with isolates of sugarcane mosaic virus, 67.8%～68.5% with sorghum mosaic virus and 38.4%～48.4% with maize dwarf mosaic virus, indicating that the pathogen of this disease on maize in Hangzhou was sugarcane mosaic virus.

病毒RNA13'端序列(1.8kb)与甘蔗花叶病毒同源性最高，达 71.5 %～ 99.1%，与高梁花叶病毒同源性次之，为 6 7.8%～ 6 8.5 %，与玉米矮花叶病毒同源性最低，仅为 38.4%～ 48.4%，从而初步认为此病害由SCMV引起。

氮素减量5%~15%时配施复合氮肥增效剂对玉米生长和含氮量影响不显著，15N和吸氮总量与不施增效剂的处理相当或有所提高。

Pot and field experiments were conducted to study the response to application rate of urea labeled with ~(15)N combined with compound nitrogen fertilizer synergists in the growth,yield,uptake and utilization rate of urea of maize,In pot experiment,the standard urea application rate is 120mg/perpot;in field experiment,the standard urea application rate is 157.5kg/hm~2. Maize with ~(15)N-lurea.

用15N-尿素进行盆栽和田间试验(盆栽试验尿素标准用量为120mg/盆，田间试验尿素标准用量为157.5kg/hm2)，研究了复合氮肥增效剂用量、尿素减量与复合氮肥增效剂配施对玉米生长、籽粒产量和氮素吸收利用的影响。

The order of surface roughness under no-tillage with different standing crop stubbles is millet forage＞maize forage＞oats＞rape, while the order of the soil wind erosion modules is rape＞oats＞maize forage＞millet forage. The larger the soil wind erosion modules are, the smaller the surface roughness is.

留有不同直立作物残茬免耕土壤地表粗糙度草谷子＞草玉米＞莜麦＞油菜，土壤风蚀侵蚀率呈现相反的趋势，地表粗糙度越大，风蚀侵蚀率越小。

Maize inbreds belonging to 3 maize heterotic groups including Reid, Tangsipingtou and compound germplasm were studied to determine the influence of genotypes, media and plant regulators on the embryo-derived calius induction and green plant regeneration. Immature embryos (1.0~2.0 mm) from selfed ears were harvested as explants. Callus could be induced from all the tested inbreds. However, plant regeneration was only obtained in 12 genotypes.

以Reid、唐四平头和其它种质等3个杂种优势类群共19份玉米自交系为试验材料，以玉米幼胚作为外植体，研究了基因型、培养基和激素对玉米幼胚愈伤组织的诱导及植株再生的影响，结果表明供试材料均能进行愈伤组织的诱导，但是仅有12个自交系能再生植株。N6和改良N6培养基有助于提高愈伤组织的质量及其生长速度。2，4-D在愈伤组织的诱导中起着关键性作用。
