摘要: 优质蛋白玉米杂交种黔单11号是在贵州恶劣灾害气候的环境条件下,选育出来的玉米新品种。经1997、2000、2001年3a试验,观察了灾害性气候对该品种的影响。结果表明:该品种抗逆性较强,播种期遇干旱久晴无雨的天气,土壤田间持水量为43.5%(正常土壤田间持水量60%)、雨水不足,出苗率在85%以上,基本达到苗齐、苗壮;拔节后期喇叭口阶段,遇到久雨少晴气候,遭受水涝灾害,土壤田间持水量达85%以上,部分低洼处被水淹,而玉米生长正常,叶色深绿,根系发达,未发现烂根现象;在抽雄、吐丝、授粉阶段,遭遇伏旱及暴风雨灾害,玉米正常抽雄吐丝授粉结实,产量未造成较大影响,基本上达到常年稳产,每公顷达到8400kg以上。

Abstract: Quality Protein Maize “Qiandan 11 hao” is under the Guizhou bad disaster climate environmental condition, Breeds selectively corn new variety. ` After 1,997, 2,000, in 2001 3years experiment, observed the disaster climate to this variety influence. The result indicated that, This variety resistance is strong, The sowing time meets arid long clearly does not have the rain the weather, The soil field capacity is 43.5% (normal soil field capacity 60%), the rain water is insufficient, Rate of seedlings emergence above 85%, Basically achieves seedling is much longer and stronger; Jointing later period trumpet-shaped object stage, Meets the continuous and incessant rains little clear climate, Suffers the water logging disaster, Soil field capacity reaches above 85%,Partial is low-lying place is flooded, But the corn growth is normal, Ye Sachem is green, The root system is developed, Has not discovered the rotten root phenomenon; Is pulling out, the spinning, the pollination stage male, Bitter experience hot summer crop damage and storm disaster, The corn normally pulls out the male spinning pollination to busload, The output has not created affects greatly, Basically reaches higher authorities to year to year the stable production, Each 667m2 achieves above 560kg.
