研究结果表明,本地区“小麦/春玉米/秋玉米”要实现三熟公顷产19500kg(其中小麦3000kg,春玉米10500kg,秋玉米6000kg)的指标,必须做到品种选择瞻前顾后,管理措施优化配套。小麦宜选用矮秆、抗倒、早熟高产品种“南大016—2894”或扬麦9号;春、秋两季玉米均应选用株型紧凑、透光性强的中熟品种掖单13。在技术措施上注重间作共生期的综合协调,处理好当季增产与全年高产的关系。小麦播幅不宜过密,空幅应达到95~100cm;春玉米采用地膜覆盖栽培,促进早熟高产;秋玉米宜适期早播,7月15~20日播种为宜,其出苗后与春玉米的共生期掌握在10d左右。
The results showed that to achieve the index of 19,500 hectares (including 3000kg of wheat, 10,500kg of spring maize and 6,000kg of autumn maize) per hectare of hay, the management of the wheat / spring corn / autumn maize should be optimized. Wheat should use dwarf, anti-down, precocious high-yielding variety “Nanda 016-2894” or Yangmai 9; spring and autumn maize should be used in compact type, strong light-translucent Yedan 13 varieties. In the technical measures to focus on the symbiotic inter-symbiotic coordination, deal with seasonal yield and full-year high-yield relationship. Wheat sowing should not be too close, the space should reach 95 ~ 100cm; spring maize mulching cultivation, and promote early maturity and high yield; autumn corn should be suitable for early sowing, July 15 to 20 sowing is appropriate, its emergence after the spring corn The symbiotic phase masters around 10d.
