【摘要】 1987—1990年的研究表明,豫麦10号是适于水肥地和旱肥地大面积种植的优良品种。在不同年型下,随着水分条件的变劣,豫麦10号生育期缩短,根茎叶的生长,分蘖成穗、幼穗分化和籽粒灌浆均受到不同程度的影响。旱作条件下,豫麦10号高产的关键,是在进一步稳定与提高亩穗数的基础上,主攻穗粒数,稳定千粒重。更多还原

【Abstract】 The result indicates that Yumai No. 10 is a good cultivar which can be largely planted in rich irrigatedv land and dryland. To some extent, the growth stages and the growth of roots, stems, leaves , single plant tillers and ears, ear differentiation and grain filling are influenced by the supply of soil water under different climatic conditions. Based on the adequate ears, increasing the number of grains per ear and stabilizing the thousand grain weight is the kev of high yield cultivation of Yumai No.10 under dryland conditions.更多还原
