catchments methods; organic silicon surface; the growth crop

The effects of catchments methods on water potential and growth of crop planted in sloping fields were studied in loess plateau of shannxi povince. The different way to rainwater catchments, for example spraying the newtype macromolecule organic silicon on the tamped slope surface, the tamped slope surface and the nature slope surface, under the slope, to determine soil water and growth of crop at timing. The experiments showed that the compacted surface soil slope with organic silicon chemical treatment catched much rainwater harvesting , to promote the crop growth. The mass was 1.1 times as the compacted surface soil slope, was 1.5 times as the nature slope.
