不同水肥处理对骏枣光合特性及产量的影响

为探究南疆沙区红枣适宜的水肥灌溉制度及黄腐酸钾肥在红枣水肥中的应用，以当地18ａ‘骏枣’为供试材料，结合大田试验，在滴灌条件下进行水肥二因素三水平试验，分析生育期不同水肥处理对骏枣光合及生长的影响。结果表明:不同处理间光合及生长指标存在差异。A1C1（高水高肥）处理净光合速率与产量最高，A2C1（中水高肥）处理叶绿素含量最高，A1C2（高水中肥）处理树体生长最旺盛。综合各项光合、生长及产量指标分析，A1(6300 m3/hm2)C1(1200 kg//hm2)对骏枣生产最为有益。

The influence of different water and fertilizer treatment on the photosynthesis characteristics and yield

In order to explore the suitable water and fertilizer irrigation system and the application of potassium porvic fertilizer in the sand area of southern Xinjiang,taking the local 18a ‘ Junzao’ jujube tree as the test material, combined with the field test, the water and fertilizer two factors and three levels were tested under drip irrigation conditions to analyze the influence of different water and fertilizer treatment on the photosynthesis and growth of Junjujube.The results showed that the photosynthetic and growth indexes differ between different treatments. The net photosynthetic rate and yield of A1C1 (high water high fertilizer) were the highest, the chlorophyll content of A2C1 (medium water high fertilizer) was the highest, and A1C2 (high water fertilizer) was the most vigorous.Based on the analysis of various photosynthetic, growth and yield indexes, A1 (6300 m3/hm2) C1 (1200 kg / / hm 2) is the most beneficial to the production of ‘ Junzao’ jujube tree.
