在旱地桃园进行垄膜保墒集雨栽培试验，研究垄膜保墒集雨技术对桃树根系分布的影响。结果表明:垄膜保墒集雨可提高桃树吸收根(直径<2 mm)的数量，增加桃树根系干重，同时可提高单果重、可溶性固形物含量及产量。

The effect of soil moisture conservation rainfull collectionin ridge film of peach trees was conducted in dry land orchard， and the effect of this technology on roots distribution of peach trees was studied . The results showed that the technology improve the number of absorption roots(<2 mm)， and the dry roots weight . The single fruit weight， yield and solubility solid are also improved .
