Effect of Spraying Biogas and KH_2PO_4 on the Leaves Photosynthetic Characteristics and Fruit Quality of Nectarine (Prumes Per Sick Var.Nectarina Maxim)
Taking nectarine (Prunus persica var. Nectarina Maxim) Yan-guang of a four-year protected cultivation as experimental material.Effect of biogas and KH2PO4 slurry spraying on nectarine photosynthetic characteristics was studied in this paper. The results showed that:
1. Spraying 0.3% KH2PO4, nectarine of light saturation point (LSP),at the time of light-saturated photosynthetic rate (Amax) and the apparent quantum yield (AQY) were higher, Light compensation point (LCP) was lower. CO2 compensati...
