澳大利亚研究人员发现，在小麦灌溉水中掺入个万分之五的钙，能减轻土壤团粒结构破坏，增强通透性，促进根系吸收水分和养分。用此法配以其他措气，可使小麦增产一倍。澳大利亚研究人员用这种万在灌溉小麦，结合抱定量磷肥和氮肥，使j。表由原子可产280公（据高到720公斤。灌溉 Australian researchers found that the incorporation of five-ten thousandths of calcium in wheat irrigation water can reduce soil aggregate structure damage, enhance permeability, and promote root absorption of water and nutrients. Use this method with other measures, can double the wheat yield. Australian researchers used this million in irrigated wheat, combined with a holding amount of phosphate and nitrogen fertilizers, to make j. Table by the atomic production of 280 km (up to 720 kg.
