| In order to better understand the effects of fertilizer on meat luffa, different nitrogen, phosphorus and
potassium fertilizer and organic fertilizer experiments were carried out in Jiangmen. The results showed that, the
effects of nitrogen fertilizer on meat luffa were the greatest maximum, increasing organic fertilizer could improve the
early yield and total yield, the fertilizer agronomic efficiency, partial factor productivity and utilization rate were
better in the low level. Through regression analysis, the equation of fertilizer effect was obtained, and the optimum
amount of fertilizer was calculated. To obtain high yield and high efficiency, in Jiangmen area, the recommended
amount of commercial organic fertilizer per 667 m2 250 kg, the optimum amount, of nitrogen, phosphorus and
potassium were as follows: N 23 kg, P2O5 11 kg, K2O 17 kg. |
