Matters needing attention in topdressing corn
1. Dosage
Topdressing of maize should be based on soil fertility, characteristics of fertilizer requirement of varieties and growth period of varieties, so as to meet the needs of maize growth and development. The plots with low soil fertility should increase the amount of topdressing, otherwise the amount can be reduced appropriately.
two。 Times
Most of the corn is fertilized once at the 9-11 leaf stage, about June 25. If the amount of topdressing is large, topdressing is carried out twice (jointing and booting fertilizer and ear-grain fertilizer). The distribution principle of two topdressing is that the secondary should account for 2 to 3 of the total amount of topdressing, and the second to 1 to 3. Light soil, such as sandy soil, is poor in keeping fertilizer and water, so it is necessary to topdressing a small amount of fertilizer many times to prevent nitrogen leaching.
3. Method
There are three kinds of topdressing methods commonly used in corn production, namely, ridge topdressing, ridge topdressing and artificial ridge plant planing. Everyone should make a choice according to the local production conditions.
As the corn varieties, soil conditions and climatic conditions planted in different regions are different, the fertilizers used are also different. Growers should pay attention to adjusting measures to local conditions and should not blindly apply the methods of other areas.
