草垄栽培是一项引进的新技术。温室中草垄栽培可提高地温2.5~4.1℃;大棚内草垄栽培可提高地温0.6~1.6℃,其中10cm土深处增温效果最显著。草垄栽培黄瓜缓苗期短,生长速度快,叶色浓绿,根系发达,植株健壮,雌花数、收瓜数增加。温室草垄栽培黄瓜早期产量比对照高37.2%,大棚内草垄栽培黄瓜的产量比对照高39.6%。草垄栽培一茬后,栽种沟内土壤有机质含量增加0.62%(温室内)和0.55%(大棚内)。草垄栽培将是克服固定式结构的园艺设施内土壤连作障碍、提高黄瓜产量、产值的优良技术之一。 Grass cultivation is a new technology introduced. Cultivation of grass mulch in the greenhouse can increase the ground temperature 2.5 ~ 4.1 ℃; grass ridge ridge cultivation can increase the ground temperature 0.6 ~ 1.6 ℃, of which the most significant 10cm soil temperature warming effect. Grass cucumber cultivated cucumber Huanmiao short, fast growth, green leaf color, developed roots, plant robust, female flowers, the number of income increased. Early cucumber cultivation in the grass ridge and ridge was 37.2% higher than that in the control, and the yield of cucumber cultivated in the grass ridge and ridge in the greenhouse was 39.6% higher than that in the control. After harvesting a crop of straw, soil organic matter content in planting ditch increased by 0.62% (in the greenhouse) and 0.55% (in the greenhouse). Grass cultivation will be to overcome the fixed structure of horticultural facilities in soil continuous obstacles and improve cucumber yield and output value of the fine technology.
