How to use water soluble fertilizer? Water-soluble fertilizer is a multi-component compound fertilizer that can be completely dissolved in water. It can be quickly dissolved in water and is more easily absorbed by crops.

1. Avoid direct flushing of water-soluble fertilizers

Due to the relatively high nutrient content of water-soluble fertilizers and compound fertilizers, do not directly irrigate according to the practice of flushing compound fertilizers, but adopt the "secondary dilution" flushing method. The purpose of secondary dilution flushing is to ensure uniform flushing and improve fertilizer utilization. Rate.

Generally, 8-10 kg can be used per mu. It is suggested that farmers can make a flushing bucket in advance, and set a switch at the bottom of the bucket. Before flushing fertilizer, first melt the water-soluble fertilizer in the flushing bucket, calculate the amount of fertilizer, turn on the switch, and let the fertilizer solution flush along with the water.

2. Water-soluble fertilizers should be applied in small amounts and multiple times

Water-soluble fertilizers should be applied in small quantities

It remains in the soil for a long time, so a small amount of fertilization method can be adopted to reduce the leaching loss caused by a large amount of fertilization, which is also in line with the characteristics of the plant roots to continuously absorb nutrients. kilogram.

Three, water-soluble fertilizer application methods should be flexible and diverse

Water-soluble fertilizer application methods should be flexible and diverse

As a new type of fertilizer, water-soluble fertilizer not only has a variety of formulations, but also has very flexible application methods compared with traditional fertilizers.

Water-soluble fertilizers can be irrigated in the soil, so that the roots of the plants are fully exposed to the fertilizers; it can be sprayed on the foliar surface to enter the plant through the stomata on the leaves to improve the absorption and utilization rate of fertilizers; it can also be drip irrigation and soilless cultivation, saving irrigation water and improving labor efficiency .

Fourth, pay attention to nutrient balance

Water-soluble fertilizers are generally watered, sprayed, or mixed into water, using drip irrigation or sprinkler irrigation. When using drip irrigation for fertilization, due to the dense and complex root growth of crops, the dependence on soil nutrient supply is reduced, and it is more dependent on the nutrients provided by drip irrigation. If the proportion of water-soluble fertilizer is not balanced, it will affect the growth of crops. .

Moreover, when applying water-soluble fertilizer, traditional irrigation methods such as flood irrigation or flowing water irrigation are prohibited, which will lead to waste of fertilizer and uneven fertilization.

5. Water-soluble fertilizer should be applied in conjunction

Most of the water-soluble fertilizers are used for top dressing. The editor of Agricultural reminds you here that water-soluble fertilizers cannot replace other conventional fertilizers in conventional agricultural production. Combining with inorganic fertilizers, water-soluble fertilizers and conventional fertilizers can not only reduce the cost of fertilization, but also give full play to the advantages of various fertilizers.

Six, water-soluble fertilizer to avoid excessive irrigation

1. When irrigating with fertilization as the main purpose, the root layer can be deeply moistened.

2. For different crops, the root growth depth is naturally different, so you can dig the soil at any time with a shovel to understand the specific depth of the root layer.

3. Excessive irrigation will not only increase the cost of irrigation, but also affect the growth of crop roots. For example, after watering, the nutrients will be leached below the root layer, which will affect crop absorption and waste fertilizers, especially urea in water-soluble fertilizers. , Nitrate nitrogen fertilizers (such as potassium nitrate, calcium ammonium nitrate, nitrophosphate fertilizers and water-soluble fertilizers containing nitrate nitrogen) are easily lost with water.
