高赖氨酸玉米杂交种按其籽粒产量不如普通玉米,但按其不可缺少的氨基酸、赖氨酸和色氨酸的含量要超过普通玉米的0.5—1倍。栽培这种杂交种玉米能够完全满足畜牧业对真正的饲料蛋白质的要求。在罗斯托夫斯克州,高赖氨酸玉米的播种面积有了很大的增加。因此,必须研究某些适合该地区土壤气候条件特定的栽培技术措施,尤其是无机肥料的施用。为了揭示高赖氨酸玉米在产量及品质方面的作用,从1973—1975年在罗斯托夫斯克州,巴扎也夫斯克地区的《克列滨斯克》国营农场和1979—1981年在巴扎也夫斯克地区的《巴扎也夫斯克》农场进行了田间试验。 High-lysine corn hybrids are inferior to common corn in their grain yield, but their indispensable amino acids, lysine and tryptophan are more than 0.5-1 times higher than ordinary corn. Cultivated this kind of hybrid corn can fully meet the animal husbandry of the real feed protein requirements. In Rostovsk Oblast, the area planted with high lysine maize has greatly increased. Therefore, it is necessary to study some cultivation techniques suitable for the soil and climatic conditions in the area, especially the application of inorganic fertilizers. In order to reveal the role of high-lysine maize in yield and quality, from 1973 to 1975 in the state farm “Kreischenk” in the Bazhyevsk region of Rostovsk region and in 1979-1981 at the Bazaar Field experiments were carried out on the “Bazar Yevsk” farm in the area of ​​Yevsk.
