1小麦节水稳产栽培技术原理1.1小麦发达的根系小麦发达的根系是高效利用土壤水的关键,特别是小麦初生根系(种子根)具有扎深2m以上的特点,能够有效利用深层土壤储水,并确保小麦健壮生长和提高抗倒伏能力。1.充分利用m土体中土壤储水,提高土壤水利用根据冬小麦生长特点,在其水分不敏感时期,通过适度水分胁迫,有意识创造一定的土壤水分缺亏条件,促进小麦根系充分下扎,减少灌溉,降低小麦总灌溉用 1 Wheat water-saving and stable cultivation techniques 1.1 Developed root system of wheat The developed root system of wheat is the key to the efficient use of soil water, especially the primary root system of wheat (seed root) with a depth of 2m deep enough to effectively use deep soil water, And ensure robust wheat growth and lodging resistance. 1. Make full use of m soil soil water storage, improve soil water use According to the growth characteristics of winter wheat in its moisture-insensitive period, through appropriate water stress, consciously create a certain soil moisture deficit conditions to promote the wheat roots under the full tie, Reduce irrigation and reduce total wheat irrigation
