In this paper it was reported the effect of S-- 07 leaf Spraied, different concentrationand in diHerent period of wheat, upon the factor of yield and its seed yield. The experimentalresult shows as follows: By way of the S-- 07 spraying in leaves of wheat, the ..lid....l thefilledgrains, the weight of kilogram of wheat can be increased, and the seed yield is.alsoincreased. Among which, the 50mg/kg S--07 leaf spraied in jointing stage of wheat got the bestresult, and the seed field increased by 516. 7kg per hmz, the growth is 13%.
