磷肥施用量对不同肥力土壤大蒜产量的影响
Effect of Phosphate Fertilizer Application Amount on Yield of Garlic with Different Fertility Levels
摘要
Abstract
The effect of application amounts of phosphate fertilizer on yield of garlic-sprout typed garlic with different fertility levels( high,medium,low) was studied by completely random design. The results showed that the moderate application amount of phosphate fertilizer could significantly increase garlic yield. The optimal application amounts of fertilizer for high yield field,medium yield filed and low yield filed were respectively nitrogen ( N) of 375. 0 kg / ha, phosphorus ( P2 O5 ) of 180. 0 kg / ha, potassium (K2 O) of 300. 0 kg / ha;nitrogen(N) of 315. 0 kg / ha,phosphorus(P2 O5 ) of 138. 0 kg / ha,potassium (K2 O) of 240. 0 kg / ha;nitrogen(N) of 255. 0 kg / ha,phosphorus(P2 O5 ) of 111. 0 kg / ha,potassium (K2 O) of 180. 0 kg / ha,the corresponding best economic outputs were 23 173. 3 kg / ha,18 323. 1 kg / ha and 13 060. 7 kg / ha,respectively.关键词
