腐植酸水溶肥对红地球葡萄生长发育影响试验

研究以红地球葡萄为对象，研究不同生长期施用腐植酸水溶肥+半量大化肥与常规足量使用大化肥对葡萄产量、品质、叶片黄化病情指数及投入产出比的影响。结果表明，使用腐植酸水溶肥后，与对照区相比成枝率提高了15.88%，果枝率提高12.14%，叶片黄化病情指数降低1.87，果实硬度提高0.16 kg/cm²，葡萄施肥量减少了37.54%，亩产量增加了332.75 kg，收入增长25.5%，投入产出比由1∶3.4提高到1∶6.2，明显优于对照。对葡萄减肥增效优化葡萄施肥方案，提升葡萄效益具有积极借鉴意义。

Effects of Humic Acid-containing Water Soluble Fertilizers on Growth and Development of Red Globe Grape

Red globe grape was taken as test material, the effects of humic acid-containing water soluble fertilizers combined with half amount of large chemical fertilizer and conventional full amount of large chemical fertilizer treatment on grape yield, quality, leaf chlorosis index and input-output ratio were investigated.The results indicated that application of humic acid-containing water soluble fertilizers could promote the growth of grape, enhance yield, and reduce the input. The branching rate was increased by 15.88%, fruit branch rate increased by 12.14%, leaf chlorosis disease index decreased by 1.87, hardness of fruit increased by 0.16 kg/cm², the amount of fertilizer decreased by 37.54%, the yield increased by 332.75 kg per 667 m², the income increased by 25.5%, the input output ratio increased from 1:3.4 to 1:6.2. This study provides positive reference for optimizing grape fertilization program and improving grape benefit.
