黑龙江省南部哈尔滨地区土壤基础肥力较低,小麦生育期间日照较短.温度较高.这对选择光钝温钝和光钝温敏型早熟、中熟耐瘠材料比较有利;选择适应于黑龙江省土壤基础肥力较高,日照较长和温度偏低的北部和东部主麦区种植的光敏温敏和光敏温钝旱肥或水肥中晚熟生态类型品种技术难点较多。针对以上这些难点,本研究对小麦杂种后代和稳定品系处理方法进行了一些改进。
Harbin, Heilongjiang Province, the lower the basic soil fertility of the soil, the shorter the sun during the wheat growth period, the higher the temperature. This is the choice of light obtuse and dull and light dull temperature sensitive early maturing, maturity barren material more favorable; choose to adapt to the soil in Heilongjiang Province There are many technical difficulties in the cultivation of the light sensitive temperature-sensitive and the light-sensitive warm and dull fertilizer or the medium and late-maturing ecological type of plants grown in the northern and eastern main wheat areas with relatively high basic fertility, long sunshine duration and low temperature. In view of the above difficulties, this study made some improvements on the treatment methods of wheat hybrid progeny and stable strains.
