塑料大棚地膜复盖栽培技术是蔬菜早熟、增产的重要措施之一。常州市郊区地处太湖流域的湖西平原,平均无霜期虽有230天左右,但每年冬春季节气温较低,影响瓜、茄类的正常育苗。近年来,由于采用了塑料大棚地膜复盖栽培技术,使蔬菜生产有了改善,增产效果是明显的。至一九八六年底,常州市郊区有地膜复盖面积246.7公顷,大棚面积33.3公顷;大棚地膜复盖的蔬菜品种有黄瓜、蕃茄、菜椒等,可提早上市二、三十天左右。随着地膜复盖栽培技术的广泛研究与应用,产生了大棚和地膜内蔬菜的追肥、灌水和早衰问题,为了探索和解决这一问题,我们在塑料大棚地膜复盖情况下,进行了黄瓜微灌方式的肥水灌溉试验,即在地膜复盖下土壤表面安装一根15毫米粗的塑料毛管,在毛管上钻1～1.7毫米的针孔,在一定的压力下把水和肥料液灌于蔬菜根部,达到灌水和追肥的目的。1983～1987年进行了上述试验研究。 Plastic greenhouse film mulching cultivation technology is one of the important measures of early maturity and yield increase of vegetables. The outskirts of Changzhou are located in the western Hunan plain of the Taihu Lake basin. Although the average frost-free period is about 230 days, the annual temperature in winter and spring is relatively low, affecting the normal breeding of melons and eggplants. In recent years, due to the use of plastic greenhouses covered cultivation techniques, so that vegetable production has been improved, increase production is obvious. By the end of 1986, there were 246.7 hectares of plastic film covered in the suburbs of Changzhou and 33.3 hectares of greenhouses. Cucumbers, tomatoes and peppercorns covered in plastic film covered in greenhouses could be put on market early for about two or three days. With the extensive research and application of plastic film mulching cultivation techniques, it has caused the top dressing, irrigation and premature aging of greenhouses and plastic mulching vegetables. In order to explore and solve this problem, we conducted the cucumber micro-mulching Fertigation irrigation irrigation irrigation test, that is, under the cover of the soil surface of the soil to install a 15 mm thick plastic capillary, drilling in the capillary 1 ~ 1.7 mm pinhole, under certain pressure water and fertilizer liquid irrigation in vegetables Roots, to achieve the purpose of irrigation and dressing. 1983 ~ 1987 conducted the above experimental study.
