base fertilizer. It accounts for about 50% of the total fertilizer , and the base fertilizer is generally applied or applied. Applying a proper amount of chemical nitrogen fertilizer as seed fertilizer at the time of sowing has a good effect on strong seedlings. Generally, 5 to 7 kg of ammonium sulfate or ammonium nitrate per a mu is suitable. Trace element fertilizers used for dressing or soaking, per kilogram of seed with 2 to 4 grams of zinc sulfate seed dressing, seed soaking using a multi-0.2% zinc sulfate.

Miao Fei. Generally, in the 4-5 leaf stage of seedlings , combined with intercropping ( or seedling ) , cultivating and weeding, it should be applied early, lightly applied and biased. If the land is poor, the base fertilizer is insufficient, and the seedlings are weak, the seedlings should be applied early. If the base fertilizer is sufficient, the soil is relatively fat, and the seedlings grow well, then the seedlings may not be chased or less.

Stalk fertilizer. Also known as jointing fertilizer, generally in the jointing stage, that is, the beginning of the growth of the base joints, about 20% -30% of the total amount of topdressing, the stalk fertilizer is mainly based on decomposed organic fertilizer, with a small amount of fertilizer , generally per acre Apply 1000 kg of manure, 10 kg of manure , or 7-10 kg of compound fertilizer . Pay attention to the application of weak seedlings to promote balanced growth of the whole field.

Spike fertilizer. It refers to the development of tassel to tetrad, and the development of the ear to the flotation stage. At this time, it is a large period of corn, about ten days before the ear, is a key period to determine the size of the ear and the number of grains. Panicle fertilizer should be reapplied, and the amount of fertilizer applied should account for 60% of the total topdressing fertilizer , and quick-acting fertilizer should be used.

Granular fertilizer. The function is to raise the roots and protect the leaves, prevent the premature aging of the corn, and increase the grain weight by prolonging the functional period of the green leaves. The grain fertilizer is lightly applied and skillfully applied, and the amount of fertilizer applied accounts for about 10% of the top dressing .

If the soil fertility is high, the base fertilizer is good, and the seedling is good, the stalk fertilizer can be applied stably and the panicle fertilizer can be applied again; on the contrary, the stalk fertilizer can be applied and the panicle fertilizer can be applied less. Insufficient panicle fertilizer, yellow-green leaf color, early dry leaves, grain fertilizer can be applied more appropriately; conversely, less or no application.
