塔里木地区的土壤含盐量很高,0—20厘米土层的含盐量可达50—70%,一般含盐量较低的荒地上也在5%(一米土层)左右。在这种含盐量很高的土壤上进行垦植,必须进行一定时期的盐土改良,才能进行生产。根据党的大辨农业、大辨粮食的方针,土壤改良阶段的时间不能过长,并应边开垦、边改良、边生产。 在改良地上种植作物,要想获得一定的产量,首先必须考虑到作物的耐盐性。作物耐盐性的高低,决定于品种的特性、土壤性质、气候条例、耕作技术等;条件适宜,作物的耐盐性就提高。兹根据我站观测资料,整理如下,
The soil in Tarim has very high salt content, with 50-70% salt content in 0-20 cm soil layer and about 5% (one meter soil layer) in the generally low salinity wasteland. Reclamation in this soil with high salinity requires salinization over a period of time before it can be produced. According to the party’s principle of distinguishing agriculture from agriculture and identifying foodstuffs, the time for soil improvement should not be too long and should be reclaimed and improved while producing. Planting crops on improved land must first take into account the salt tolerance of the crop in order to achieve a certain yield. Salt tolerance of crops depends on the characteristics of varieties, soil properties, climatic regulations, farming techniques, etc .; suitable conditions, the salt tolerance of crops to improve. According to my station observation data, organized as follows,
