有机肥是作物生长发育过程中必不可少的肥料,增施有机肥是增产、增收、用地养地的有效途径。 (一)、有机肥对土壤水分利用率的影响。 有机肥本身具有高吸特性,可以提高土壤的蓄水能力,促进作物的根系发育,提高作物对土壤水分的利用率。据试验,亩施有机肥2000公斤较1000公斤的水分利用率提高15.6%,较对照(不施有机肥)提高38.9%。 (二)、有机肥对土壤养分含量的影响 有机肥含有丰富而齐全的营养成分,施入土壤后,一部分养分物质分解为速效养分被当季作物吸收利用,大部分养分贮存于土壤中,形成作物的后效
Organic fertilizer is an indispensable fertilizer in the process of crop growth and development. Adding organic fertilizer is an effective way to increase production, increase income and increase land use. (A), the impact of organic fertilizer on soil water use efficiency. Organic fertilizer itself has a high suction characteristics, can improve soil water storage capacity, promote root development of crops and improve crop utilization of soil moisture. According to the test, the water use efficiency of 2000 kg of KMS over 2000 kg was 15.6% higher than that of CK (no organic fertilizer application), up 38.9%. (B), the impact of organic manure on soil nutrient content Organic fertilizer contains rich and complete nutrients, applied to the soil, part of the nutrients decomposed into quick-acting nutrients absorbed by the crop, most of the nutrients stored in the soil, the formation of After the effect of the crop
