“肥农”生物有机肥在雷州半岛地区糖蔗上的应用研究

为了研究“肥农”牌生物有机肥对雷州半岛地区糖蔗的农艺性状、产量、品质及对甘蔗病虫害发生的效用和对土壤理化性状的影响。通过采用对含有效活菌数≥2.0×107个/g，有机质≥40%，N+P2O5+K2O≥15%的“肥农”牌生物有机肥在雷州半岛地区甘蔗上进行使用的方法，研究其对糖蔗的农艺性状、产量、品质、病虫害发生的效用和对土壤理化性状的影响。结果表明，肥农生物有机肥对萌芽率的影响不显著，但显著提高了糖蔗的分蘖率、株高和茎数，同时，该肥还增加蔗茎产量和公顷含糖量。在虫害方面，“肥农”生物有机肥的施用使虫口率降低了23.4%，其中白蚁虫口率降低了7.69%，天牛虫口率降低了15.71%。结论，该肥料具有促进分蘖、高生长、有效茎数生长的作用，同时具有显著的增产、增糖、增收效果且可以降低甘蔗虫害的发生。

Application of Agricultural Compound Microbial Fertilizer on the Sugar Cane in Leizhou Peninsula Area

Research brand "Feinong" biological organic fertilizer on the Leizhou Peninsula of sugar cane agronomic traits, yield, quality and utility of the sugarcane diseases and insect pests occurrence and effects on soil physical and chemical properties. By used of brand "Feinong" biological organic fertilizer of effective microbes number ≥ 2.0×107 cells/g, organic matter ≥ 25% and N P2O5 K2O ≥ 15% used in Leizhou Peninsula sugar cane. Study the agronomic traits, yield and quality of sugar cane, plant diseases and insect pests occurrence of utility and its influence on soil physical and chemical properties. The results showed that agricultural compound microbial fertilizer had no significant impact on the germination rate of sugarcane, but significantly increased the rate of sugarcane tillering, plant height and stem number. And the same time, this fertilizer also increased sugarcane and sugar production. In the aspect of insect, application of agricultural compound microbial fertilizer declined the pest rate by 23.4%, which declining pest rate of termite and beetles were 7.69% and 15.71%, respectively. The fertilizer can promote tillering, high growth, the role of effective tiller growth, at the same time had significant production, add sugar, income effect and could reduce the occurrence of sugarcane pests.
