本文以紧凑型品种掖单１３号和平展型品种丹王１３号为材料．进行为期两年高产示范试验。结时表明：在相同栽培条件下，每公顷为４５０００株、５２５００株、６００００株、６７５００株、７５０００株，掖单１３比丹玉１３分别增产１２．６９％、２０．３６％、２２．５１％、２６．０２％、４５．２１％；单株生产力增加１７．４９ｇ、２５．４４ｇ、２９．２０ｇ、３２．０８ｇ、４４．２１ｇ；穗粒重增加３７．８０ｇ、４４．９０ｇ、３０．６０ｇ、３８．９０ｇ、５７．６０ｇ；穗粒数增加６５粒、９５粒、７６粒、８２粒、１６０粒；空秆率减少１１．７、１２．５、１３．８、１５．３、１６．４个百分点，充分显示了紧凑型玉米的耐密性能．同时，还示范并改进了紧凑型玉米的配套栽培技术．
In this paper, a compact variety Yedan 13 and flat varieties Dan Wang 13 as the material. A two-year high-yield demonstration test. Results showed that: 45000, 52500, 60000, 67500 and 75000 plants per hectare under the same cultivation conditions, Yedan 13 increased 12.69%, 20.36% and 22.51 %, 26.02% and 45.21% respectively. The productivity of single plant increased by 17.49g, 25.44g, 29.20g, 32.08g, 44.21g. The weight of spike increased by 37.80g, 44.90g, 60g, 38.90g, 57.60g; the number of spikelets increased by 65, 95, 76, 82 and 160; the empty stalk rate decreased by 11.7,12.5,13.8,15.3,16 .4 percentage points, fully demonstrated the tightness of compact corn performance. At the same time, it also demonstrated and improved the compact corn cultivation technology.
