白土梁林场羊场苗圃位于黄河南岸,土壤粘重,含碱量大(土壤PH值7.5-8.5),给育苗工作带来较大的困难。为了解决这个问题,我们通过反复实践,逐步掌握了盐碱地育苗的方法。主要措施是: 一、改土治碱1.春翻耙地,切断毛细管,春耕整地灌水,防止盐碱上升;及时排除苗床积水,防止土壤含水饱和或由于灌溉不当而使地下盐分上升。采用深水压碱,灌后36小时及时排水洗碱。2.平整土地,加强田间管理,划小灌溉地块。为防止局部起碱,灌溉时进水要均匀。
White soil Lianglin Farm sheep nurseries located in the southern bank of the Yellow River, soil sticky, alkali content (soil pH value 7.5-8.5), nursery work to bring greater difficulties. In order to solve this problem, we have gradually mastered the method of raising seedlings in saline-alkali soil through repeated practice. The main measures are: First, soil amendments alkali 1. Spring rake to cut off the capillary, spring plowing irrigation to prevent salt and alkali rise; timely rule seedbed water, to prevent soil water saturation or due to improper irrigation and underground salt rise. Using deep-water pressure alkali, 36 hours after irrigation in a timely manner drain washing alkali. 2. Leveling the land, strengthening field management, planning small irrigation plots. To prevent local alkalization, water should be fed evenly.
