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. Phosphorus also has the effect of promoting the development of the root system, in particular 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 seedling stage, it will affect later growth.
2. Fine Phosphorus: Superphosphate is easy to absorb moisture and agglomerate when it is stored. When it is applied, it must be smashed and sifted in order to absorb the root system.
3. Phosphorus is concentrated: Phosphorus is easily fixed by iron, aluminum, and calcium in the soil and fails. Therefore, it should be applied in the hole or in the shoot to fix the phosphorus around the seed or the root or to convert the phosphorus and mud into a mud. It is conducive to the absorption of plant roots and improves the survival rate and resistance of plants.
4. Phosphorus and organic fertilizers are mixed: In particular, calcium, magnesium, and phosphate must be mixed with organic fertilizers to convert insoluble phosphates in phosphate fertilizers into available phosphorus for plants. Because phosphorus fertilizers are mixed in organic fertilizers, the contact with soil can be reduced. , thereby increasing the fertilizer efficiency of phosphate fertilizer.
5. Tiered Phosphorus: Because of the mobility of phosphate fertilizers in the soil, phosphate fertilizers are applied both to the bottom layer and the superficial layer. General Mushi 10 kg.
6. Mixed use of nitrogen and phosphorus: Nitrogen fertilizer and phosphate fertilizer can be used in a balanced manner to balance nutrients and promote the roots of the crop to lay a foundation for lush 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 spray: Phosphate fertilizer effect is long, basal fertilizer can be used once 2-3 crops, generally do not need to apply phosphate fertilizer for each crop, so 1 to 2 years of basal fertilizer can be applied to a phosphate 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. Phosphorus in soil: Phosphate fertilizers such as superphosphate are acidic fertilizers and are suitable for use in neutral and alkaline soils, whereas calcium, magnesium phosphate fertilizers are best used in partially acidic soils.
10. Can not be mixed with alkaline fertilizers: plant 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.
