不同地区玉米杂交种在俄罗斯阿穆尔州第一积温带的光合作用特征

The Photosynthetis Character of Maize Hybrid in the Different Maize Region of the First Accumulated Temperature Zone in Armu of Russia

通过本试验，为阿穆尔州第一积温带筛选主栽品种，抑制玉米面积大幅度下滑，解决阿穆尔 州饲料匮乏问题。试验结果可以看出，收获期边三2号子粒含水量为最低，经济效益最高。如合理 密植，适宜的土壤肥力，边三1号、斯拉夫生物学产量最高，可作青贮饲养推广。

The objective of this experiment is to select main cultivated variety in the first accumulated temperature zone of Armu in order to control reduced planting area of maize on a large scale and to solve the lack of feed in Armu. The experiment result showed that grain water content of Bansan No. 2 was the lowest and economic benefit was the highest. With proper close planting and suitable soil fertility, biomass of Bansan No. 1 and Slav was the highest and can be released as ensilage.
