How to use NPK water-soluble fertilizers to improve fertilizer absorption and utilization

As a new type of fertilizer, NPK water-soluble fertilizer is not only versatile but also very flexible compared with traditional fertilizers. NPK water-soluble fertilizer can be poured into the soil, so that the roots of plants can fully contact the fertilizer; it can be sprayed along with the leaves, and enter the plant through the leaves, so as to improve the absorption and utilization rate of fertilizers.

Advantages of water-soluble fertilizer: First, the integration of water and fertilizer, realizing the integration of water and fertilizer, high fertilization efficiency, and reducing the total amount of fertilization, exerting the synergistic effect of fertilizer and water, so that the utilization efficiency of fertilizer and water is equal to the utilization efficiency of water and water. Significant improvement. Secondly, the fertilizer effect is fast, which can meet the nutritional needs of high-yielding crops.

Disadvantages of water-soluble fertilizers: First, the price of water-soluble fertilizers is generally high, which is not conducive to popularization. Second, it is firm and not easy to preserve for a long time in the soil. The amount of fertilization should be strictly controlled. If the amount is small, it will cause fertilizer loss. It will not only reduce the economic benefits of fertilization, but also fail to achieve the purpose of high yield, high quality and high efficiency. It will also cause water pollution, which is not conducive to sustainable development.

1. Water-soluble fertilizer should be applied reasonably

A small amount of application is the most important principle of water-soluble fertilizer fertilization, which conforms to the characteristics of uninterrupted plant root nutrients and reduces the soluble loss caused by one-time large-scale fertilization. Small amount of repeated application is the most important reason for the high amount of water-soluble fertilizer.

Pay attention to the nutrients and balanced water-soluble fertilizers that are usually applied, applied or applied through irrigation equipment. Especially under drip irrigation conditions, the root system is large and dense, and the nutrient supply of the soil depends more on the nutrients provided by drip irrigation. This is especially true for sandy soils, which have higher requirements for a reasonable ratio and concentration of nutrients. If the fertilizer formula is unbalanced, it will affect the growth of crops and cause fertilizer shortage.

The safest method in safe production is to experiment with a small amount of fertilizer, and reduce the concentration when it is found that the leaves are harmful. Some large growers can buy handheld conductors to monitor fertilizer concentration, which is more suitable for areas with high water and salt concentrations.

2. Calculate the application amount of water-soluble fertilizer

Fertilizers are available in both water-soluble and liquid forms. No matter which one you use, you need an appropriate amount of water to dilute the concentration of the fertilizer before use. It is easy to block the mist and nozzles, affecting the working efficiency. It is best to quickly promote the dissolution of fertilizer and water. If there are a large number of elements with a specification of 5 kg behind the water-soluble fertilizer, it means that the dilution factor is 600 times, that is, (5×2) jin x 600 times = 6000 jin, that is, the amount of water used is 6000 jin. Stir well after adding water.

3. The details of water-soluble fertilizer application depend on

If drained with water, it is recommended to dilute with a little water and then apply the diluted solution with water. If it is withdrawn directly with water, the effect will be affected.

Drip irrigation is a highlight of the efficient use of water-soluble fertilizers. Drip irrigation not only greatly saves water resources, and the fertilizer utilization rate reaches more than 90%, but also saves labor costs.

Foliar spraying, the foliage is not suitable for large fertilizers, but if the crops do need some large amounts of elements to spray, this is similar to urea foliar spraying.

The fertilization time should be chosen before 10 am and after 4 pm, avoiding fertilization under strong sunlight. Fertilizers are best avoided when fertilizing, especially foliar fertilizers. Do not apply in rainy days to reduce fertilizer loss.

4. Pay attention to the application of water-soluble fertilizers and remember

Pay attention to the uniformity of fertilization. In principle, drip irrigation is more effective if it is slower, especially for elements with poor mobility in the soil (such as phosphorus), prolonging the fertilization time can greatly improve its utilization rate. Drip irrigation and fertilization in the dry season is recommended to be completed within 2 to 3 hours. The soil is starved of water, the sooner the better.

Avoid overwatering. Generally, the root depth should be kept moist. Depending on the crop, the depth of the root layer varies greatly. You can dig up the soil with a shovel at any time to see the specific depth of the root layer. Over-irrigation not only wastes water, but also severely scours nutrients below the root layer, wastes fertilizer, and reduces crop yields. Especially urea and nitrate nitrogen fertilizers (such as potassium nitrate, calcium ammonium nitrate, nitrophosphate fertilizer, water-soluble fertilizers containing nitrate nitrogen) are easily lost with water.

Avoid direct application, use the second dilution method. Because water-soluble fertilizers are different from ordinary compound fertilizers, farmers cannot use conventional fertilization methods, resulting in uneven fertilization, burnt seedlings, and weak seedlings. Secondary dilution ensures uniform fertilization and improves fertilizer utilization.

Strict control of the dosage, small amount and multiple times, is the most important principle, so as to meet the characteristics of non-intermittent absorption of nutrients. The fertilizer efficiency of water-soluble fertilizer is higher than that of general compound fertilizer, and the dosage is relatively small. Because of its fast speed, it is not easy to stay in the soil for a long time, so it is necessary to strictly control the amount of fertilizer applied.
