【摘要】 枣树与多种农作物在物候期和大量需水肥时期上相互交错,缓和了枣粮水肥和光照竞争两个主要矛盾。枣粮间作经济效益显著,平均增益3～7倍。平原枣区间作模式为南北行向,树高5～7m,株行距3.5～4.5m×12～15m,枣粮布局采用“高——低——高”或“高——低——中——低——高”型。更多还原

【Abstract】 As for the Chinese dates and many field crops, the phenology phase and the water-and-fertilizer-enormously-needed period, crisscross, which alleviates the three contradictions of demanding water, fertilizer, and sunlight at the same time. The intercropping of the Chinese dates and the field crops has obvious economical benefits, with the yield of 3-7 times more. The models of the intercropping are "high-low-high" or "high-low -middle-low-high" .更多还原
