利用日光温室冬季反季节生产鲜食玉米,试验揭示温室日低温是影响鲜食玉米本田生育期的决定因子,探明温室温度保持恒稳,鲜食玉米本田生育天数不会因播期不同而改变,设施反季节栽培应选用花期短、灌浆速率快的品种,采取育苗移栽定植,种植密度为52 500～60 000株/hm2,鲜食玉米商品穗产量可稳定超过6 000kg/hm2,纯收益达到75 000元/hm2。本试验创新了京郊设施农业生产模式,配套技术简便易行,经济效益高,为京郊设施农业多元化高效生产提供了新选择。
The use of solar greenhouse winter off-season production of fresh corn, the experiment revealed that greenhouse temperature is the impact of low-temperature fresh corn Honda growth determinants, proven greenhouse temperature remains stable, fresh corn Honda days will not vary due to different sowing date In the anti-season cultivation, the plants with short flowering period and fast filling rate should be selected for transplanting. The planting density should be 52 500 ~ 60 000 plants / hm2. The yield of fresh corn should be stable over 6 000 kg / hm2. Reached 75 000 yuan / hm2. This experiment innovates the agricultural production mode of facilities in Beijing suburbs, the matching technology is simple and convenient, and the economic benefits are high, which provides a new choice for diversified and efficient agricultural production in facilities in Beijing suburbs.
