1985—1986年在中等肥力下对3种不同叶夹角玉米杂交种的研究表明,在本试验的密度范围中,平展叶中单2号产量与密度呈显著负相关(r=-0.779~* n=9),直立叶(无叶舌)中单2号产量与密度呈极显著正相关(r=0.970~(**) n=9),上挺叶 Mo17/Lg×黄早四产量与密度呈显著正相关(r=0.797~(**) n=9)。在光合性状与产量关系研究中发现,平展叶中单2号最适 LAI 是3.5,直立叶中单2号最适 LAI 是4.5,上挺叶 Mo17/Lg×黄早四最适 LAI 是4.0。本试验结果表明,在试验密度中产量最高的是直立叶中单2号5000株/亩,其次是上挺叶 Mo17/Lg×黄早四4000株/亩,分别比平展叶中单2号3000株/亩的最高产量增产20.4%和11.4%。试验还表明,在常规玉米育种基础上,开展选育、应用上挺叶和直立叶杂交种,似是提高中、上等肥力玉米田产量水平的一个有效途径。

Vertical leaf and middle ear hybrid corn Yuyu 2 and Yuyu 5 planted withsuitable density have the highest yield potentiality whether to adopt direct se-eding or interplanting with wheat.(the former is preferable.)Open an flat andbig ear hybrid Danyu 13 has fairly high yield superiority in looser density,thus interplanting is in favor to it.Both direct seeding and interplanting aregood for intermediate type hybrids Yuyu 1 and Yuyu 3.According to the resu-lts of pass analysis,the main cullivate measures were raised....

无论直播或套种,密度适宜时竖叶中穗型杂交种豫玉2、5号增产潜力最大,鉴于麦垄点(套)种时不易密植,故更适合麦后直播,若能在麦垄点(套)种时适宜密植其增产潜力更大;平展叶大穗型的丹玉13号在稀植时具有一定增产优势,因而更适合麦垄点(套)种;中间型的豫玉1、3号介于前两类之间,直播或点(套)种均可。本文对各类杂交种在不同条件下的适宜密度及其密度适宜时对施肥的产量响应等进行了研究,并由通径分析结果提出了各类杂交种栽培管理的主攻方向。通过对竖叶型杂交种增产原因的分析,提出竖叶大穗型可兼容耐密和大穗两大高产要素,应作为玉米高产育种的主攻目标。

Data of microclimate of the paddy field recorded by a micrometeorologi- cal data logger system was analyzed intensively and the microclimatic chara- cters during late rice grain filling period was discussed in detail.Data showed that the quanta value in erect-leaf cultivar was almost as much as two times comparing the one with horizontal-leaf in 15 centimeters height inside the canopy;difference of temperature recored in the surface of plant and leaf between two cultivars inside the canopy was negligible;relative...

Data of microclimate of the paddy field recorded by a micrometeorologi- cal data logger system was analyzed intensively and the microclimatic chara- cters during late rice grain filling period was discussed in detail.Data showed that the quanta value in erect-leaf cultivar was almost as much as two times comparing the one with horizontal-leaf in 15 centimeters height inside the canopy;difference of temperature recored in the surface of plant and leaf between two cultivars inside the canopy was negligible;relative humidity was also recorded at the 1.5 meter height.Experimental data indicated the better utilization of solar energy was the most important factor for contributing higher yielding potential in erect-leaf cultivars.Aside from this,reliability for using this micrometeorological data logger system was also verified.

本文分析了由微气候“数据记录仪”(Datalogger)自动收集的资料,探讨了稻田在水稻灌浆期的小气候特征。结果表明:直立叶品种比平展叶品种在冠层以下15cm处光量子相差1倍左右;植株温度及冠层叶面温度品种间差别较小,稻田1.5m高处空气湿度品种间不存在差别。初步认为直立叶型品种能更充分利用光能,这是直立叶型品种产量高于水平叶型品种的重要原因。此外还对Datalogger所获得的田间气候资料可靠性进行检验、肯定。
