无土栽培省肥省水,病虫害较轻,优质高产,适合立体栽培和工厂化生产,是大幅度提高蔬菜产量的有效措施.去冬我所在不加温温室内利用地热线水培青韭初获成效,头刀每平方米收割青韭6.79斤,二刀每平方米收割青韭4.45斤,每平方米总产11.24斤,折合亩产7485斤,可供应元旦、春节,青韭,丰富市场供应,满足群众需要.地热线无土栽培青韭具有以下优点:1、生长周期短、供应有保证,在严寒冬季利用地热线水培青韭,头刀为40天,二刀仅25天,较露地小拱棚加草苫覆盖青韭,缩短生长周期一个月可保证“双节”供应.2、增产潜力大,经济效益高.水培青韭
Soilless culture fertilizer and water, light pests and diseases, high quality and high yield, suitable for three-dimensional cultivation and industrialized production, is an effective measure to substantially increase the yield of vegetables. Results, head knife per square meter harvest green leek 6.79 pounds, two knives per square meter harvest green leek 4.45 pounds, 11.24 pounds per square meter of total output, equivalent to 7485 pounds per mu, available New Year’s Day, Spring Festival, green leek, rich market Supply, to meet the needs of the masses. Earth’s soilless cultivation of green leek has the following advantages: 1, the growth cycle is short, the supply is guaranteed, the use of geothermal hot water in the frosty winter to cultivate allium, head knife for 40 days, Compared with the small open field shed plus grass 苫 cover green leek, shortened growth cycle one month to ensure “double section ” supply .2, yield potential, high economic efficiency.
