利用地膜作大棚的围幕、天幕和扣小拱棚,小拱棚内采用2根8.3瓦/米电加温线短期加温,大棚外侧四周围草苫,这些措施使栽培畦内地上5厘米最低气温比露地高10.3℃。利用主架栽培比常规架栽培亩净增值500元左右。选用叶三品种作副架比长春密刺每亩多收200元,以株距15厘米左右为宜。农大12号黄瓜比长春密刺产值高25.17％。无土苗带基质定植比同龄有土苗早期产量高。在生产上利用多层覆盖提早定植,采用主副架栽培,选用适宜品种等是提高大棚黄瓜产值的有效栽培措施。
The use of plastic film for the greenhouse curtain, the sky curtain and small Shed, small arch shed with two 8.3 W / m electric heating line short-term heating, shed around the outside around the grass 苫 these measures to cultivate 畦 5 cm minimum temperature on the ground 10.3 ℃ higher than the open air. Cultivation of the main frame than the conventional cultivation of acres of net added value of 500 yuan. Selection of three varieties of leaves for the next frame than Changchun thorn more than 200 yuan per acre to 15 cm spacing is appropriate. Nongda 12th cucumber than the Changchun spike output value of 25.17%. Soilless seedlings with matrix colonization than the same age soil seedlings early high yield. Multi-layer coverage in the production of early planting, the use of main and sub-frame cultivation, selection of suitable varieties is to increase greenhouse cucumber production value of effective cultivation measures.
