河南农业大学讲师梁金城等人,深入豫东、豫北盐碱地区,经过较长时间的苛苦钻研,探索出了一种新型盐碱地改良技术,打孔造筛淋盐治碱技术,取得了较好的治碱改土效果。现简介如下: 打孔造筛淋盐治碱法,就是在有盐碱的地块,先挖一些直径40厘米、深30厘米的坑,在坑内灌水10公斤左右,然后借助水的滑腻作用,用长3—4 Henan Agricultural University lecturer Liang Jincheng and others, in-depth Yu, saline-alkali areas in northern Henan, after a long period of harsh study, to explore a new type of saline-alkali soil improvement technology, Good Alkali soil improvement effect. Now briefings are as follows: Drilling salt sieve salt treatment method is in the salty land, dig some diameter 40 cm, 30 cm deep pit, irrigation in the pit about 10 kg, and then with the role of the water creamy, Use long 3-4
