Effect Of Several Slow/Controlled Release Fertilizers On The Fairway Of Golf Course

Several domestic and international golf slow / controlled release fertilizers as the focus on this research, for Golf fertilizer users in selecting fertilizers provide the basis, for the slow / controlled release fertilizer researchers provide a theoretical basis. They take the indicator of balds recoverate rate , above-ground biomass , chlorophyll , turfgrass and soil's nitrogen , phosphor, potash. The study results showed:1. "GAOFU" IBDU slow release fertilizer takes a better efficiency for a long time. Therefore it is better to use GAOFU IBDU slow release fertilizer on fairway turfgrass in spring.2. "TOP GREEN" slow release fertilizer could offer enough nitrogen to the turfgrass on fairway, and contains more nitrogen in the soil in the last spring. So it is good to use "TOP GREEN" slow release fertilizer on fairway turfgrass in spring.3. "BEST" controlled release fertilizer is the best appilication in autumn. In addition, the "BEST" controlled release fertilizer is well on turfgrass quality of the appearance of the recovery.4. "AIDIER" controlled release fertilizer isn't so excerlent in this study. It is proved that "Aidier" controlled release fertilizer isn't apt to take on fairway in autumn.5. The bald spot could be recovered in turf by "GAOFU" fairway controlled release fertilizer at a high speed. And"GAOFU" fairway controlled release fertilizer provide enough potassium to turfgrass in summer. So it is better to use"GAOFU" fairway controlled release fertilizer on fairway turfgrass in summer.
