In recent years, with the promotion and application of corn no-till seeders with fertilizing devices, the application of summer corn seed fertilizers has become more and more common. Application of seed fertilizer can promote the growth and development of corn seedlings, and is conducive to the cultivation of strong seedlings, laying a good foundation for the high yield of summer maize. However, there are still many problems in the application of the seed fertilizer in the current production. If the fertilizer is improperly applied, it is easy to cause germination or burning, which causes unnecessary loss to the corn production. Therefore, the following points should be noted:
Selecting fertilization varieties, controlling the amount of urea and other urea-based fertilizers should not be used as seed fertilizers, otherwise it is easy to burn seedlings, and nitrogen, phosphorus and potassium compound fertilizers can be applied. In the corn seedling period, the amount of fertilizer needed is small. In order to reduce waste, the application rate of the seed fertilizer should not be too large. Generally, the dosage per mu is about 10 kg, especially when the alfalfa is planted, the application amount of the seed fertilizer should be strictly controlled.
In order to avoid seed fertilizer application, in order to avoid direct contact between seeds and fertilizers, the seedlings should be separated from the fertilizer by 7-10 cm. When artificially planted, the seeds should be fertilized for lateral application or interspecific. Deep application.
To ensure that the soil is applied to the plot of soil fertility, the seedlings should be poured under the seed or planted, so as to "dilute" the seed fertilizer, which can reduce the burning phenomenon caused by a large number of fertilizers to a certain extent.
