| 摘 要： | 分别在博罗和惠阳进行田间试验,以普通硫磺粉为参照,研究甜、糯玉米施用经精细加工的速效硫肥的应用效果。在供试土壤有效硫含量低于临界值情况下,施硫可增加甜、糯玉米商品产量,显著提高生产效益并优化甜玉米品尝风味。博罗甜玉米施硫平均增加利润702.36元/hm2,产投比(VCR)为8.19;惠阳糯玉米施硫处理平均增加利润1425.30元/hm2,VCR高达12.88。RRS适宜用量为60kg/hm2,其增产增收效果显著优于相同用量的普通硫磺粉。

| Abstract: | Field trials were conducted respectively in Boluo and Huiyang to evaluate the effects of Rapid Release Sulphur (RRS), through comparing to common elemental sulphur powder, on sweet and wax corns. Results illustrated that S fertilization increased commercial yields and production profit for both sweet and wax corn, and improve tasting sensation of sweet corn as well. In average, S fertilization resulted in 702.36 yuan/hm2 and 1 425.30 yuan/hm2, with VCR of 8.19 and 12.88, respectively for the Boluo sweet cor... |
