The pot experiments have been carried out to approach the influen:es of soil salt on:growth and productivity of Spring wheat

The ;results are shown as follow; Spring wheat is sensitive to soil salt during seedlings and its ability of saltresistance increases after seedling

Meanwhile

the influences of different manure on Spring wheat are different

Supplying P can enhance larger ability of saltenduring than supplying N and promote the better growth of Spring wheat

Under different condition of soil salt supplying P can develop more functive leaves

result in larger speed of accu-mulating aboveground drymatter and promote the yield more remarkable comparedr with supplying N.
