在呼图壁县用大田和小区，覆膜和露地，7月6日和7月11日两个播期，及两个高密度试验，比较了特早熟玉米新玉引96－1与中南5号、中南2号、ZP111及当地农家种六十黄在冬小麦收获后复种的植株性状、生殖特征及产量因素。新玉引96－1平均株高207．8cm，穗位在植株1／3处，出苗后41天抽雄，籽粒灌浆期43天，单穗粒重97．1g，全生育期在88天以内。植株抽雄。吐丝和散粉在3天内进行，活秆成熟，收获指数高达49．29％，未发现严重病虫害。大田示范0．33hm2，单产达7816．5kg／hm2，全生育期所需≥10℃积温小于2000℃。考虑到冬小麦收获后覆膜种植玉米的农耗积温和成熟保证率，天山北坡平原区从7月5日到10月5日的92天里，可利用有效积温超过2125℃。因此，该品种可适合在北疆复种。
In Hutubi County with fields and plots, mulching and open field, July 6 and July 11 two sowing dates, and two high-density test, compared the special precocious corn new Jade cited 96-1 and South 5 No.2 Zhongnan No.2, ZP111, and local farmers’ cultivar Sixty Yellow in the plantation, reproductive traits and yield factors of winter wheat after reapling. Xin Yu cited 96-1 average height 207.8cm, ear position in the plant 1/3, 41 days after emergence tasseling, grain filling 43 days, grain weight 97.1g, the whole growth period of less than 88 days. Plant tasseling. Silking and loose powder were carried out within 3 days. Live stalks matured and the harvest index was as high as 49.29%. No serious pests and diseases were found. Daejeon demonstration 0.33hm2, yield of 7816.5kg / hm2, the whole growth period of ≥ 10 ℃ accumulated temperature is less than 2000 ℃. Taking into account the winter wheat after plastic film mulching corn planting yield and maturity assurance rate, Tianshan northern slope plain from July 5 to October 5 92 days, the effective accumulated temperature can be used more than 2125 ℃. Therefore, the breed may be suitable for multiple cropping in the northern region.
