| Abstract: | The influences on the growths and the yields of maize by two different cultivation methods of the setting seedlings and the direct seeding protected with the plastic film are studied under the condition of mulching The result showed that the method of the direct seeding protected with the plastics can dispel the negative influece of the growth retardation in certain period caused by setting seedlings and make the maize blossom in earlier time It also can increase the leave areas of plant and prolong the filling stage of maize,Therefore it's effect in increasing output is 17 08% |
