摘要: 通过施用2种土壤改良剂,改善陕北旱区土壤物理结构和微生物活性,测定其对玉米生长及产量的影响。结果表明,基施土壤改良剂均能显著提高玉米株高、茎粗、鲜重、子粒NPK含量、产量。施用微生物土壤改良剂,相对单纯改善土壤物理结构的高分子土壤改良剂,更有利于促进子粒N和P的吸收,提高子粒品质。

Abstract: Two kinds of soil modifiers were applied to improve soil physical structure and microbial activity in northern Shaanxi arid region, and its effects on growth and yield of maize were determined. The results showed that the basal application of soil modifier could significantly increase the plant height, stem diameter, fresh weight, grain NPK content and yield. The application of microbial soil modifier was more beneficial to the absorption of N and P and improved the grain quality than to the polymer soil modifier which only improved the physical structure of the soil.

Key words: soil improver, maize, yield, northern Shaanxi arid region
