摘　　要：研究应用派诺克产品对甘蔗的增产增糖效果。田间试验施用派诺克K3900g/ha和派诺克P1950g/ha,测定甘蔗的农艺性状,叶绿素含量和土壤含水量。施用派诺克K和派诺克P,能显著地增加甘蔗叶绿素a和叶绿素总量,甘蔗分蘖率显著提高,每公顷有效茎多,蔗茎前中期生长明显加快,最终蔗茎极显著地高于对照,极显著地增加原料蔗产量和蔗汁锺度;同时能改善土壤理化性状,土壤含水量显著提高。派诺克K在播种和大培土时各施用量的一半,派诺克P在分蘖初期和蔗茎伸长初期各喷施一半,效果更好。在广西蔗区土壤有机质普遍较低的情况下,施用派诺克K3900g/ha和派诺克P1950g/ha能显著提高蔗茎产量和蔗计锺度。The article studies the effects of Penergeric on increasing the yield and sugar degree of sugarcane. Penergeric K 3900g/h and Penergeric P 1950g/h are used in the cane fields to test the agronomic trait, chlorophyll content and soil water content. To apply Penergeric K and Penergeric P can observably increase the chlorophyll a content and chlorophyll quantum, the tiller rate of cane , and the amount of productive stems per hectare. The cane stems grow quickly during the early and middle periods, and finally the stems grow observably higher than that of the comparison, so that the yield and sugar content of cane increase greatly. Meanwhile, the physicochemical properties of soil can be improved with higher soil water content. Penergeric K is applied with half of the dosage in sowing and earth-up periods and Penergeric P is sprayed with half of the dosage in the early periods of tillering and stem growing to get better effects. Under the condition of lower content of soil organic matters in Guangxi sugarcane planting areas, the application of Penergeric K and Penergeric P can greatly increase the yield and sugar content of sugarcane.
