基点黄骅县赵家堡大队,通过几年来的科学实验和生产实践证明,在土壤含盐量1.6％(60厘米土体内)以上的重盐碱地,通过台田、条田、沟洫围田、平整土地、作畦圈水等整地改良措施,利用天然雨水淋洗土壤盐碱的方法,开展植树造林,已使勃海滩发生了很大变化。该大队现有林木10万多株(其中紫穗槐4万墩),一般林木生长良好。6年生的榆树,平均高7.90米,平均胸径8.14厘米;合作杨平均高8.02米,平均胸径8.84厘米。并每年收割紫
Based on several years of scientific experiments and production practices, the base point Huanghua County Zhaojiabao Brigade has proved that it is feasible to land through saline fields of Taida, Tiantian and Gouba in fields of saline soil with a salinity of 1.6% (within 60cm of soil) , As a circle of water and other soil preparation measures to improve the use of natural rainfall leaching of soil salinity method to carry out afforestation, has made great changes in Bo beach. The brigade has more than 100,000 existing trees (including Amorpha fruticosa 40000), the general growth of trees is good. 6-year-old elm trees, an average height of 7.90 meters, an average diameter of 8.14 centimeters; cooperation Yang average 8.02 meters high, with an average diameter of 8.84 cm.
