What kind of foliar fertilizer is used for corn seedlings?
In the process of corn growth, foliar fertilizer should be used properly. But some corn seedlings are small, so what kind of foliar fertilizer do corn seedlings use? Let's find out together.
What kind of foliar fertilizer is used for corn seedlings?
1. Choose foliar fertilizer with good quality: when purchasing foliar fertilizer, we should pay attention to whether the factory name, location, production date and packaging are complete, while liquid fertilizer should pay attention to solubility and precipitation.
two。 In the case of insufficient base fertilizer, foliar fertilizer based on nitrogen and phosphorus fertilizer can be selected; when the application of basal fertilizer is sufficient, foliar fertilizer based on trace elements should be selected, and foliar fertilizer containing growth regulators can also be selected according to the different needs of crops.
3. Spraying foliar fertilizer must strictly control the spraying concentration, especially for the foliar fertilizer containing growth regulators. For example, 0.5 μ g triacontanol can promote seed germination, but more than 1 μ g will inhibit seed germination. Therefore, all kinds of foliar fertilizer should be sprayed in strict accordance with the concentration required in the instructions.
When should corn use foliar fertilizer?
1. When encountering diseases and insect pests, the use of foliar fertilizer is beneficial to improve plant disease resistance.
two。 When the soil is too acidic, alkaline or too salty, it is not conducive to the absorption of nutrients by plants.
3. Full fruiting period
4. After the plant suffers from air injury, heat injury or freezing injury, choosing an appropriate time to use foliar fertilizer is beneficial to alleviate the symptoms.
When applying foliar fertilizer, it is best to choose early morning or evening when the wind is not strong. In case of heavy rain after spraying foliar fertilizer, it should be sprayed again. If a small area is sprayed on the back of the leaf, the absorption rate of nutrients on the back of the leaf is faster than that on the surface of the leaf.
