摘要
应用绿色根源节水灌溉方式对西红柿进行灌溉处理,相对于其他灌溉方式,得到了节水和提高产量的实验结果,并确定了埋管最佳深度为距离地表约30 cm和浇灌量0.75 L/次。根据西红柿的实验,应用绿色根源节水灌溉方式到道边树和干旱丘陵果园的节水灌溉,并研制了绿色根源灌溉系统的机械装置。以1年龄杏树为试验对象,试验表明果树的成活率和生长性与一般灌溉方式相比有明显的提高,而且相对于地下滴灌方式,绿色根源灌溉系统具有成本低,易控制,可移动,易操作和故障少等特点。
Green root irrigation method was used to irrigate the tomatoes, and the experimental result proved that water consumption was decreased, and production was improved. The best depth of irrigation was 30cm to the surface of the earth and water consumption was 0.75 L each time for tomatoes. Based on the experimental result of tomatoes, the green root irrigation method was used to irrigate the trees on the sides of the road and fruiter in droughty district. Mechanical equipment was developed for green root irrigation system. The result of experiment on almond at the age of one showed that the survival rate and features of growth had been improved than other irrigation method. Contrasted with the subsurface drip irrigation, green root irrigation has lower cost, easier control, easier operation and lower failure.
