我国的果园多建在丘陵山地,近年来连续严重干旱,使得地下水资源越来越少,地下水位下降。因此,因地制宜,广泛采用节水灌溉新技术已成为提高果树产量、品质和果园经济效益的关键措施。一穴灌:穴灌是在树冠投影的外缘挖穴,将水灌入穴中,以灌满为度,穴的数量依树冠大小而定,一般为8—12个,直径30厘米左右,穴深以不伤粗根为度,灌后将土还原。该法用水经济,浸湿根系范围广大而均匀,不会引起土壤板结,简便易行。随着农业工程技术的发展,穴灌技术也在不断地改进和发展。近
China’s orchards and more built in the hills and mountains, continuous severe drought in recent years, making fewer and fewer groundwater resources, water table down. Therefore, according to local conditions, the widespread adoption of new technologies for water-saving irrigation has become a key measure to increase fruit yield, quality and orchard economic benefits. A hole irrigation: hole irrigation is crowned outside the crown projection, the water into the hole to fill the degree, the number of holes depending on the size of the crown, usually 8-12, about 30 cm in diameter, Depth to not hurt the rough root for the degree, the soil will be restored after irrigation. The method of water economy, soaking a wide range of root and uniform, will not cause soil compaction, simple and easy. With the development of agricultural engineering technology, irrigation technology is also constantly improving and developing. near
