膜下沟灌技术是自2007年以来省市蔬菜10项主推技术之一,沟灌技术投资小,亩投入200元左右就能起到节水、节肥、降低湿度、减轻病害、提高蔬菜产量和质量的作用,是目前适宜推广的一项节水灌溉技术。它与地面大水漫灌相比可节水30%左右。技术要点:根据种植习惯,在前茬蔬菜收获后,施足基肥,深翻后整成南北方向的畦。可以选用起垄栽培,一般垄高10～15厘米。每垄的畦面上可以种植2行蔬菜,两行之间留一个浅沟,把薄
Under furrow irrigation technology is one of the 10 main push technologies of vegetables in provinces and cities since 2007, the investment in furrow irrigation technology is small, investment of 200 yuan per mu can play a role in saving water, saving fertilizer, reducing humidity, reducing diseases and increasing vegetable yield and quality The role is currently a suitable promotion of a water-saving irrigation technology. It can save 30% water compared with flood irrigation on the ground. Technical points: According to planting habits, after the harvest in the former crop vegetables, Shizujifei, deep turn into the north-south after the turnaround. Ridge can choose to cultivate, the general ridge height 10 to 15 cm. Each ridge of ridge can grow 2 rows of vegetables, leaving a shallow groove between the two lines, the thin
