Fertilizer Mixture

Fertilizer mixed with fertilizer

1.Superphosphate can not be mixed with grass ash, lime nitrogen, lime and other alkaline fertilizer, otherwise the organic acids in the soil will be neutralized, so that the insoluble phosphate will be more difficult to dissolved and the crop can not absorb and use the superphosphate directly. 2, Calcium phosphate, magnesium phosphate and other alkaline fertilizer can not be mixed with ammonium nitrogen fertilizer, and if the alkaline fertilizer mixed with ammonium nitrogen fertilizer, there will promote the ammonium volatilization. 3, Chemical fertilizers can not be mixed with bacterial fertilizer, because fertilizer has high aquosity, corrosivity, volatility. For example, when rhizobia mixed with other bacterial microbes, it will kill or inhibit viable bacteria growth.

The mixture of herbicides and fertilizers

1.Herbicides mixed with fertilizersis one kind of pesticides mixed with fertilizersresearched and practiced mostly. The mixture of nitrogen, phosphorus and potassium and 2,4-D or Sima Jin (selective herbicide) can increase the yield of corn. 2. We find from the effect of nitrogen fertilizer on weed growth and herbicide effect in sorghum field that with the increase of nitrogen application level, the number of weeds will increase after 15-30 days of sowing. And at the same time, with the atrazine exist, the amount of nitrogen and the amount of biomass also can beincreased. 3. the application of herbicides have different influences on fertilizer and plant mineral nutrition.Different herbicides have different performances. The application of phosphate fertilizer and potassium fertilizer can remove the inhibition of corn growth, and it can also increase plant dry weight, phosphorus and potassium content as well as it can decrease magnesium, calcium content.

Plant growth regulator and fertilizer mixture

The influence of fertilization and mineral nutrient on plant growth. In the mineral nutrient, nitrogen has a significant effect on root growth and cytokinin production and transportation.Therefore, insufficient nitrogen supply will enhance the synthesis of abscisic acid in the plant and it also will lead to Plant aging. Nitrogen has great influence on gibberellin. For example, the loss of nitrogen supply of potato, the gibberellin content of potato stem will decrease significantly. At the same time, the level of abscisic acid also will be increased drastically. Therefore, fertilization is closely related to the rational application of plant growth regulators. For example, apply nitrogen fertilizers to cereal crops will promote the synthesis of gibberellins and provide a high level of nitrogen nutrition which will promote plant stem growth and increase the risk of lodging. In order to avoid such situation, we should apply nitrogen fertilize with chlormequat to inhibit the synthesis of gibberellin.
