塔里木垦区自1958年开垦以来,由于缺乏向盐碱作斗争的经验,各场冬小麦经过春灌后都出现不同程度的死亡现象,个别地区相当严重,影响产量很大.如1960年胜利十四场因此造成冬小麦减产30%左右;1961年个别连队也有类似情况发生.春灌死亡的主要原因是,由于播种任务紧张,忽视了洗盐质量,土壤含盐量还很高,从播种到返青将近半年的时间内,盐分又从新回升到地表,经过灌水后,表层盐分被水溶解携带至根系活动层(20—30厘米),
Tarim reclamation area since the reclamation in 1958, due to the lack of experience in the fight against salt, the winter wheat after the spring flooding have varying degrees of death, in some areas is very serious, affecting the yield, such as the 1960 victory 14 Resulting in about 30% reduction in winter wheat production in 1961. The main reason for the death of spring irrigation was that due to the tight sowing task and the neglect of salt washing quality, the salinity of the soil was still very high, ranging from sowing to returning to green for nearly six months Within the salt again rose back to the surface, after irrigation, surface salt dissolved by water to the root activity layer (20-30 cm)
