本研究通过随机区组试验研究了不同播种期对水果玉米农艺性状及产量的影响。结果表明,播种时期对水果玉米农艺性状及产量均有影响。随播种期的推迟水果玉米生育期缩短,株高和穗位高增高,虽然植株总叶片数不变,但青苞收获期叶面积减少,导致其品质降低,产量减小,经济效益降低。在新疆南疆水果玉米宜在适期播种范围内尽量早播(4月13日播种)。 In this study, randomized block experiments were conducted to study the effects of different sowing dates on agronomic characters and yield of fruit maize. The results showed that the sowing date had an impact on the agronomic characters and yield of fruit maize. With the delay of sowing date, the growth period of fruit maize was shortened, and the plant height and ear height were increased. Although the total number of leaves in the plant remained the same, the leaf area at the harvest stage decreased, resulting in lower quality, lower yield and lower economic benefit. Fruit and maize in southern Xinjiang should be sowed as soon as possible in the suitable sowing range (April 13 planting).
