不同磷肥处理对丝瓜生长发育、产量及品质的影响OA

In this study,we used Chunsi 2 and Zhesi 301 as experimental materials to investigate the effects of different phosphate fertilizer treatments on the growth,yield,and quality of sponge gourd(Luffa cylindrica).The results showed that different phosphate fertilizer treatments had little effect on the main agronomic traits and yield of sponge gourd.Calcium superphosphate treatment could significantly(p＜0.05)reduce the first female flower node of Zhesi 301.Under different phosphate fertilizer treatments,there were no significant differences in root,stem,and leaf biomass of the two varieties.The total phosphorus content in root and leaf of Chunsi 2 was the highest under monoammonium phosphate treatment,while the total phosphorus content in leaf of Zhesi 301 was highest under calcium superphosphate treatment.Besides,calcium superphosphate treatment significantly increased the crude protein content of Chunsi 2.In conclusion,the effects of different phosphate fertilizers on vegetative growth,yield,and fruit quality of sponge gourd varied.Considering all indicators,calcium superphosphate is recommended for sponge gourd cultivation.
