[0027] Example one:
[0028] The present invention includes the following components, and the mass ratio of each component is as follows:
[0029] 1000 parts of organic fertilizer;
[0030] 24 parts of urea;
[0031] 17 parts of superphosphate;
[0032] 14 parts of potassium chloride;
[0033] 1 part of borax;
[0034] 2.2 parts of copper sulfate;
[0035] 2.9 parts of ferrous sulfate;
[0036] 3.5 parts of phosphorus pentoxide.
[0037] The fertilizer is divided into several groups: Group A is: organic fertilizer, urea, superphosphate, potassium chloride, borax, copper sulfate, ferrous sulfate:
[0038] Group B is: urea, potassium chloride and phosphorus-free oxide;
[0039] Use component A for base application and component B for topdressing.
[0040] Topdressing is divided into two times: the first use of component B, the second use of urea during the vigorous growth stage.
