滴灌是近几十年发展起来的新灌溉技术,具有省水、增产、节能、适应不同地形和自动化程度高等优点。各地试点证明,对果树澍灌比传统地面灌优越得多,特别是在干旱半干旱地带具有重要意义。为了发挥我区林特产品资源优势,推广灌溉新技术,1984年在省水利厅协助下,我区建立了丹凤葡萄、苹果滴灌试点,1985年开展试验研究工作,现就苹果滴灌试验情况和初步效果简述如下:(一)试区概况:试点设在丹凤县鱼岭水库老虎原,其地域条件是:1、土壤:为浅山带重粘土,深度0～60厘米,平均容重1.36克/厘米~3,颗粒
Drip irrigation is a new irrigation technology developed in recent decades. It has the advantages of saving water, increasing production, saving energy, adapting to different topography and high degree of automation. Pilots from all over the world have proved that there is much more superiority to fruit tree irrigation than traditional ground irrigation, especially in arid and semi-arid zones. In order to give full play to the advantages of Lintou resources in our region and popularize new irrigation technologies, in 1984, with the help of the provincial water conservancy department, we established a pilot project of Daphne grapes and apple drip irrigation in our district and carried out experimental research in 1985. Nowadays, The preliminary results are summarized as follows: (a) Overview of the trial area: The experimental site is located in the tiger original of Yu Ling Reservoir in Danfeng County. Its geographical conditions are: 1. Soil: heavy clay with shallow depth of 0-60 cm and average bulk density of 1.36 g / Cm ~ 3, particles
