摘要:

【目的】研究不同施钾量对滴灌花生光合特性及产量的影响,为筛选新疆滴灌花生钾肥最佳施肥量提供依据。【方法】采用花育9610和黑花5号为材料,设置4个施钾处理:0 kg/hm2(K0)、150 kg/hm2(K1)、225 kg/hm2(K2)和300 kg/hm2(K3),比较不同施钾量对花生光合参数、叶绿素含量及荧光参数的影响,分析不同施钾量对滴灌花生光合特性及产量的影响。【结果】花育9610和黑花5号在K2处理下提高了净光合率、蒸腾速率和气孔导度与K0相比分别提高了9.67%、60.49%和13.53%,降低了胞间CO2浓度,分别降低了14.25%、55.97%和15.14%;于出苗后80 d,K2处理叶绿素含量、施钾量达到峰值,分别为2.92和3.01 mg/g;花育9610和黑花5号在整个生育期中ETRPSⅡ最大光化学效率(Fv/Fm)、PSⅡ潜在光化学活性(Fv/Fo)均在出苗80 d K2处理达到最大值,分别为98.34、0.84;4.24,98.57、0.85和4.32,较K0处理有显著提高;花育9610和黑花5号不同施钾肥较不施钾肥在单株结果数、百果重、百仁重、出仁率均有所增加,不同施钾处理所表现的产量差异为K2>K3>K1>K0,花育9610和黑花5号以K2处理产量最高,分别为9 428.71 和9 968.35 kg/hm2,较不施肥增产33.66%和35.26%。【结论】花育9610和黑花5号在出苗80 d的功能叶叶绿素a/b、光合速率、气孔导度、蒸腾速率、电子传递速率(ETR)、PSⅡ最大光化学效率(Fv/Fm)、PSⅡ潜在光化学活性(Fv/F0)均在K2处理量下达到最大值。不同施钾处理产量表现为T2K2>T1K2>T2K3>T1K3>T2K1>T1K1>T2K0>T1K0,花育9610和黑花5号产量均为K2处理达到最高,分别为 9 428和9 968 kg/hm2,并且各施肥处理黑花5号单产均高于花育9610,增施钾肥对花生增产效果显著。

Abstract:

【Objective】 To study the effects of different potassium application rates on photosynthetic characteristics and yield of peanut under drip irrigation in the hope of providing a basis for peanut planting in Xinjiang. 【Methods】 Huayu 9610 and Heihua 5 were used as experimental materials, and four potassium application treatments were set: 0 kg/hm2 (K0), 150 kg/hm2 (K1), 225 kg/hm2 (K2) and 300 kg/hm2 (K3). The effects of different potassium application rates on photosynthetic parameters, chlorophyll content and fluorescence parameters of peanut were compared, and the effects of different potassium application rates on photosynthetic characteristics and yield of peanut under drip irrigation were explored. 【Results】 The net photosynthetic rate, transpiration rate and stomatal conductance of Huayu 9610 and Heihua 5 were significantly increased under K2 application, and the intercellular CO2 concentration was decreased. Compared with K0, they were increased by 9.67%, 60.49% and 13.53%, 14.25%, 55.97% and 15.14%, respectively. The chlorophyll content in leaves reached the peak of 2.92 mg/g and 3.01 mg/g on the 80th days after emergence, respectively. During the whole growth period, ETR, PSⅡ maximum photochemical efficiency (Fv/Fm) and PSⅡ potential photochemical activity (Fv/Fo) of Huayu 9610 and Heihua 5 reached the maximum values of 98.34,0.84 and 4.24,98.57,0.85 and 4.32 at 80 d K2, respectively, which were significantly higher than those of K0. The number of pods per plant, 100-pod weight, 100-kernel weight and kernel rate of Huayu 9610 and Heihua 5 were higher than those without potassium fertilizer. The yield difference of different potassium treatments was K2>K3>K1>K0. In the experiment, the highest yield of Huayu 9,610 and Heihua 5 was 9,428.71 kg/hm2 and 9,968.35 kg/hm2, respectively, which was 33.66 % and 35.26% higher than those without fertilizer. 【Conclusion】 The chlorophyll a/b, photosynthetic rate, stomatal conductance, transpiration rate, electron transport rate (ETR), maximum photochemical efficiency of PSⅡ (Fv/Fm) and potential photochemical activity of PSⅡ (Fv/Fo) of functional leaves of Yuhuayu 9610 and Heihua 5 on the 80 th days after emergence reach the maximum under K2 application rate. The yields of different potassium treatments are T2K2>T1K2>T2K3>T1K3>T2K1> T1K1>T2K0>T1K0. The yield of Huayu 9610 and Heihua 5 reach the highest under K2 treatment, reaching 9,428 kg/hm2 and 9,968 kg/hm2, respectively. The yield of Heihua 5 is higher than that of Huayu 9610, indicating that the increase of potassium fertilizer in Xinjiang has obvious effect on peanut yield.
