Abstract

Изобретение относитс  к сельскому хоз йству и может быть использовано на территории пустынь и полупустынь аридной зоны дл  восстановлени  потенциального плодороди  засоленных земель. Цель изобретени  - повышение эффективности и ускорение процесса опреснени  п очвогрун- тов на заданную глубину. Перед промывкой нарезают временные дрены 1 и каналы 2. Затем подают воду на полосу 3, расположенную вдоль трассы дрены 1, дл  опреснени  почвенного сло  на глубину заложени  дрен. После спада грунтовых вод на полосах одновременно подают воду и во временные каналы 2. Дрены нарезают глубиной 0,9-1,5 м и на рассто ние одна от другой 10-50 м. При посто нно действующем глубоком дренаже , а также за счет временных дрен и испарени  уровень грунтовых вод снижаетс  на 0,8-1,0 м за 5-10 сут. 2 ил.The invention relates to agriculture and can be used in the desert and semi-desert areas of the arid zone to restore potential fertility and saline lands. The purpose of the invention is to increase the efficiency and accelerate the process of desalination and turn of the soil to a predetermined depth. Before washing, temporary drains 1 and channels 2 are cut. Then water is supplied to strip 3 located along drain route 1 in order to desalinate the soil layer to the depth of draining. After the fall of groundwater on the lanes, water is simultaneously supplied to the temporary canals 2. The drains are cut to a depth of 0.9-1.5 m and at a distance from one another 10-50 m. With constant deep drainage, and also due to temporary drains and evaporation the groundwater level decreases by 0.8-1.0 m in 5-10 days. 2 Il.
