Fertilize Unscientific, Nutrient Element Also Can Fight!

Fertilize unscientific, nutrient element also can "fight"!

1. Balanced fertilization

Excessive or excessive application of simple fertilizers to crops not only leads to waste of fertilizers and increased production costs, but also leads to the shortage of other nutrients. In food crops, farmers often apply nitrogen fertilizer, resulting in a flourishing crop or lodging; In fruit trees, vegetables and other commercial crops, too much fertilizer application, often resulting in crop lack of magnesium, calcium deficiency. When fertilizing, according to the structure of fertilizer required by crops and the capacity of soil fertilizer supply, "quantity out for input" should be achieved to maintain the balance of nutrient elements.

2. Apply special fertilizer

When fertilizing, special compound fertilizer should be given priority to, with simple fertilizer as auxiliary. If there is no special crop fertilizer, for fruit trees or vegetables that need large amounts of potassium, such as tubers and roots, the fertilizer can be added on the basis of general compound fertilizer.


3. Apply organic fertilizer

Organic fertilizer is the fertilizer of overall balanced nutrition, not only contain a lot of necessary plant, medium and microelement, still contain rich organic nutrient. After organic fertilizer is applied into soil, it can effectively improve the physical and chemical condition and biological characteristics of soil, mature soil, enhance the ability of soil maintaining and supplying fertilizer and buffering ability, and create good soil conditions for crop growth.

At the same time, organic fertilizers and fertilizers can be applied in a reasonable manner, and complement and promote each other, which is conducive to crop absorption, improving fertilizer utilization rate, buffering or reducing the antagonism between nutrients


4. Change fertilization methods

If zinc fertilizer and phosphate fertilizer mix, can produce certainly "the gram". Therefore, phosphate fertilizer should be applied as the base fertilizer, and zinc fertilizer should be applied as the top fertilizer. Rhizospheric fertilization should be the main method for a large amount of elemental fertilizers such as NPK, NPK can adopt the method of spreading, and phosphate fertilizer can adopt the method of concentrated fertilization. The method of leaf spraying and root application should be adopted according to the degree of deficiency. The method of seed dressing, seed soaking and root dipping can also be adopted to limit the trace elements in the small range of the root and avoid contact with a large number of elements.

5. Fertilize according to soil characteristics

In the sandy soil lacking potassium, nitrogen fertilizer and potassium fertilizer should be applied together, but the application of potassium fertilizer at one time should not be excessive, because potassium ions can also have an antagonistic effect on the absorption of calcium, magnesium and ammonium, which will cause the lack of calcium and magnesium in crops. The application of nitrogen fertilizer on acidic soil should not be excessive, otherwise it will be difficult to absorb calcium ions when the ammonium ion concentration of crops is higher. Some malarial maladies in apple areas are calcium deficiency caused by excessive nitrogen application.
