摘要：

为了确定糯玉米高山反季节栽培适宜种植密度，通过糯玉米‘闽糯0018’闽东高山反季节栽培不同种植密度对主要性状及经济效益的影响进行初步研究。结果表明，栽培密度在5.7万株/hm2时，鲜苞商品性状和产量能够得到比较好的协调，取得较好的经济效益。密度过高或过低会影响鲜苞产量及经济效益。糯玉米‘闽糯0018’闽东高山反季节大面积栽培时种植密度应控制在5.7万株/hm2左右。

Abstract:

In order to determine the optimum planting density of the alpine-anti-season waxy corn, the effect of cultivation density on the main traits and economic benefits of the waxy corn ‘Minnuo 0018’ was studied in Mindong. The results showed that: when the planting density was 57000 plants/hm2, both the commodity traits and yield of fresh ear could be balanced better, and reached to higher economic benefit. Too high or too low planting density could weaken the yield of fresh ear and economic benefit. Therefore when the alpine-anti-season waxy corn ‘Minnuo 0018’ was cultivated in a large scale in the eastern Fujian, the optimum density was 5700 plants/hm2.
