【摘要】 黄土丘陵区干旱缺水、无霜期短、自然条件差,旱作玉米是主要的种植作物,玉米产量低而不稳。腐植酸配方肥与地膜覆盖是两种节水抗旱和提高玉米产量的技术,通过对这两项技术的综合实验得出:(1)腐植酸配方肥提高了肥料的利用率,增强了作物的抗逆性,延长了肥效,改善了土壤结构,明显提高了作物的产量。(2)腐植酸液态地膜对土壤增温效果明显,保持了土壤湿度,促进了作物苗期的生长发育。腐植酸配方肥与腐植酸液膜覆盖相结合能更有效地调节作物生长,提高玉米产量。更多还原

【Abstract】 The Loess Hills are drought and water shortage and frost-free period is short,so natural conditions are poor. Dry-land corn are the main crops,corn production is low and unstable.Humic acid formula fertilizer and mulching are two kinds of drought and water-saving technologies to improve corn production.Through a comprehensive test of these two technologies,the results showed that:(1) HA-formula fertilizer increased fertilizer utilization,enhanced crops resistance,extended the fertilizer,improved soil structure,and significantly increased crop production.(2) effect of humic acid liquid clear plastic film on the soil warming can keep the soil moisture to promote crop growth and seedlings. Humic Acid Fertilizer formulations combined with humic acid liquid film covering are more effective in raising crop growth to improve corn production.更多还原
