针对目前市场上盐碱地改良剂商品较多,但是生物改良剂相对较少,国家没有统一的标准的现状,结合酒泉市移民乡土壤盐渍化程度高、板结很严重的情况,开展盐碱地生物改良剂试验与研究项目,本实验通过开展4种生物改良配方对重度盐碱地栽植枸杞生长量及产量影响的相关试验,筛选出了枸杞盐碱地栽植最佳生物改良剂,河沙10 m3/667m2、炉渣3m3/667m2、秸秆300kg/667 m2、纯羊粪3 m3/667 m2、硫酸亚铁50kg/667 m2,促进高生长量的幅度为25%,促进粗生长量的幅度为27.39%,促进产量增长幅度为26.94%。
In view of the current market, there are more products of saline-alkali soil improver, but there are relatively few biological modifiers and there is no unified standard in the country. Combining with the high degree of soil salinization in the immigrant township of Jiuquan City, Experiments and research projects, the experiment carried out by four kinds of bio-modified formulations on the heavy saline-alkali soil growth and yield of Lycium barbarum-related experiments were screened out of the wolfberry saline alkaline planting the best biological amendments, sand 10 m3 / 667m2, slag 3m3 / 667m2, straw 300kg / 667m2, pure sheep manure 3m3 / 667m2, ferrous sulphate 50kg / 667m2, the rate of promoting high growth is 25%, the rate of promoting coarse growth is 27.39% 26.94%.
