以新冠龙辣椒为供试材料,研究了不同施肥种类对拱棚辣椒生长发育、产量及光合特性的影响,结果表明:T_4辣椒植株的株高、开展度最大,分别为104.3、90.6 cm,T_1辣椒单果重、果长、果粗均最大,分别为101.6 g、25.49、4.86 cm。T_1辣椒叶片总叶绿素含量最高为66.7mg/g,根系活力最强为100.6μg/(g·FW·h)。T_5辣椒叶片净光合速率下降幅度最高为6.6μmol/(m~2·s),T_1、T_2辣椒叶片净光合速率下降幅度最低,波动于1.3~2.5μmol/(m~2·s)。T_3辣椒叶片气孔导度下降幅度最高为2 658.1 mol/(m~2·s),T_2、T_5辣椒叶片气孔导度下降幅度最低,波动于386.7~428.7 mol/(m~2·s)。T1辣椒叶片蒸腾速率下降幅度最高为4.7 mmol/(m~2·s),T_5辣椒叶片蒸腾速率下降幅度最低为1.1 mmol/(m~2·s),辣椒叶片胞间CO_2浓度下降幅度最高为436.8μmol/mol。T_1辣椒的小区产量、产量、效益均最高,分别为340.1 kg、96 448.5 kg/hm~2、162 865.6Yuan/hm~2,T_3辣椒的小区产量、产量、效益最低,分别在260.8 kg、74 338.5 kg/hm~2、124 888.5Yuan/hm~2。
The effects of different fertilizers on growth, yield and photosynthetic characteristics of Caragana korshinskii were studied. The results showed that plant height and spreading degree of T_4 pepper plants were the highest, which were 104.3 and 90.6 cm respectively, Fruit weight, fruit length, fruit are the largest, respectively 101.6 g, 25.49,4.86 cm. T_1 capsicum had the highest total chlorophyll content of 66.7 mg / g and the highest root activity of 100.6 μg / (g · FW · h). The net photosynthetic rate of pepper in T_5 decreased by 6.6μmol / (m ~ 2 · s), and the decrease of net photosynthetic rate of pepper in T_1 and T_2 was the lowest, with a fluctuation of 1.3 ~ 2.5μmol / (m ~ 2 · s). Stomatal conductance of leaves of T_3 decreased by 2 658.1 mol / (m ~ 2 · s), while the decrease of stomatal conductance of leaves of T_2 and T_5 was the lowest, fluctuating from 386.7 to 428.7 mol / (m ~ 2 · s). The highest transpiration rate of pepper leaves was 4.7 mmol / (m ~ 2 · s), the lowest one was 1.1 mmol / (m ~ 2 · s), and that of pepper leaves was the highest 436.8 μmol / mol. The yield, yield and benefit of T_1 pepper were the highest, which were 340.1 kg and 96 448.5 kg / hm ~ 2,162 865.6Yuan / hm ~ 2, respectively. The production, yield and benefit of T_3 pepper were the lowest in 260.8 kg, 74 338.5 kg / hm ~ 2,124 888.5 Yuan / hm ~ 2.
