Phosphorus is an important component of the plant nucleus. It plays an important role in cell division and the differentiation and development of various organs of plants, especially flowering and fruiting. It is an indispensable element in physiological and metabolic activities of plants.
Phosphorus is mainly concentrated in the seeds of plants in the plant. Phosphorus is stored in the seeds, which is conducive to the healthy growth of the seedlings in the early stage. Phosphorus also has a good effect on improving plant resistance, cold resistance and drought resistance, especially promoting the development of lateral and fine roots.
Since phosphorus has many effects on plants, most flowers are dark green when they are deficient in phosphorus, and plant growth is hindered. In order to better improve the plant's stress resistance, it is necessary to apply phosphate fertilizers correctly and reasonably. The specific operations are as follows:
1. Phosphorus at the seedling stage: Phosphorous uptake at the seedling stage of crops is the fastest. If phosphorus deficiency occurs at the seedling stage, it will affect later growth.
2. Screening fine phosphorus: Superphosphate easily absorbs moisture during storage, and when applied, it is required to break through the sieve to absorb the root system.
3. Concentrated application of phosphorus: Phosphorus is easily fixed by iron, aluminum, and calcium in the soil and is ineffective. Therefore, it should be applied at the acupuncture point and in order to fix the phosphorus around the seed or the root or turn the phosphorus and mud into a mud. Its use is conducive to plant root absorption, improve the survival rate and resistance of plants.
4. Phosphorus and organic fertilizers: In particular, calcium, magnesium and phosphate fertilizers must be mixed with organic fertilizers to convert insoluble phosphates in phosphate fertilizers into available phosphorus for plants. As phosphorus fertilizers are mixed in organic fertilizers, they can be reduced with soil. The contact, thereby increasing the fertilizer efficiency of phosphate fertilizer.
5. Stratified phosphorus: Because of the mobility of phosphate fertilizers in the soil, phosphate fertilizers should be applied to both the bottom layer and the superficial layer. General Mushi 10 kg.
6. Mixed use of nitrogen and phosphorus: The combination of nitrogen fertilizer and phosphate fertilizer can balance nutrients, promote the down-rooting of crop roots, and lay a foundation for the growth of flower seedlings.
7. Spraying outside the roots: In the later stages of the growth of the plant, the roots are aged and the ability to absorb nutrients is weakened, often causing phosphorus deficiency. At this time, water-soluble potassium superphosphate can be sprayed on the leaves so that the phosphorus can enter the plants through the holes or the stratum corneum of the leaves. Flowers can be used at concentrations of 1% to 3%, spraying on sunny mornings or evenings.
8. Appropriate amount of phosphorus: Phosphate fertilizer has long effect, base fertilizer can use 2 to 3 crops at a time, generally do not need to apply phosphate fertilizer to every crop, so 1 to 2 years can be applied to a single base fertilizer. At the same time, the applicable amount should be calculated according to different plants and soil fertility to ensure the balance of nutrient elements of nitrogen, phosphorus and potassium.
9. Because of soil phosphorus: fertilization, such as calcium superphosphate is an acidic fertilizer, suitable for application in neutral, alkaline soil, and calcium magnesium phosphate fertilizer is best applied in the partial acidic soil.
10. Can not be mixed with alkaline fertilizer: grass ash, lime, etc. are all alkaline substances, if mixed with the use of phosphate fertilizer, will significantly reduce the effectiveness of phosphate fertilizer, generally should be applied again every 7 to 10 days.
