为了筛选出对小麦病害防治效果理想的药剂,以烟农1212为试验材料,采用6种不同药剂,设7个试验处理,通过DTOPSIS法将7个处理和对照小麦的纹枯病发病率、茎基腐病病株率、白穗率、每平方米穗数、穗粒数、千粒重和产量等性状指标归纳为一个具有可比性的量化综合指标,对不同处理进行综合评价.结果表明,Ci值最大的为处理2,为0.6507;其次为处理6,为0.6172.因此,在鲁东半岛地区建议每100 g麦种使用酷拉斯(27％苯醚·咯菌腈·噻虫嗪)500 mL进行拌种.

玉米在适宜种植密度基础上再增加密度,其产量的增减除与品种本身遗传特性有关外,很大程度上还取决于当年的气候状况,若当年气温适宜,光照充足,雨量充沛,适当增加密度可能会提高产量,反之会降低单位面积产量.

用2个品种4个播期研究了夏玉米的植株性状、经济性状及对粗缩病发病率的影响.结果表明:麦田套种玉米粗缩病发生率高,收获穗数降低,限制了产量的提高；麦后晚直播,植株生长矮小,粒重严重偏低,是制约产量的重要因素；麦收后6月15日直播产量最高,是山东省夏玉米主产区最佳播期.

To reveal the yield components of wheat yield of the three factors on the relative importance,using correlation and path analysis,on the Shandong Province from 2008 to 2009 wheat area of high fat group trial of 165 wheat varieties (lines) yield and its components were analyzed.The results showed that: the coefficient of variation of yield components size: spikes> grains per spike> 1000-grain weight;Yield components and yield related degree: spikes> grains per spike> 1000-grain weight;Partial correlation analysis,spike and thousand seed weight and yield were highly significant positive correlation,the number and yield of grain was positively related to yield components are the partial correlation between the significant negative correlation;The direct path coefficient of three yield components on yield is positive,which is the result of partial correlation analysis is consistent.According to the analysis and ecological conditions in Shandong Province and current characteristics of growing conditions,breeding and cultivation of wheat should be based on large groups of varieties of multi-spike-based,and to stabilize grains per spike,1000-grain weight increased.

根据莱州市玉米生产情况,总结出夏玉米高产栽培技术,包括选用优良品种,进行播前种子处理,适期足墒播种,及时间苗定苗、培育壮苗,氮、磷、钾平衡施肥,病虫草害综合防治和适当晚收获等措施.

小麦的高产、稳产是保证我国粮食供求平衡,增加农民收入的重要途径,近年来,由于受诸多因素的制约,山东省莱州市高产地块小麦产量长期徘徊在500kg左右。2008年农业部开始在全国开展高产创建活动,莱州选择冬小麦洲元9369作为小麦高产创建主栽品种,根据品种特征特性探讨其超高产栽培技术,以促进全市小麦产量上水平。
