近年来,围绕发展高效设施农业,我市园艺技术指导站通过多年生产实践,摸索总结出了适合我区种植的大棚番茄-芹菜-莴苣周年高效栽培模式。该模式一般每667m2产番茄5000kg、芹菜4000kg、莴苣3000~4000kg,全年每667m2产值15000元左右,净效益10000元以上。现将该模式主要栽培技术介绍如下。 In recent years, around the development of efficient facilities agriculture, our city horticultural technology guidance station through years of production practice, groping summed up for our region planting greenhouse tomato - celery - lettuce annual and efficient cultivation mode. The pattern generally produces 5000kg of tomato per 667m2, 4000kg of celery and 3000 ~ 4000kg of lettuce. The annual output value of each 667m2 is about 15,000 yuan and the net benefit is over 10,000 yuan. Now the main cultivation techniques introduced in this mode are as follows.
