The use of water-fertilizer integrated technology to apply water-soluble fertilizer brings a lot of convenience to agricultural production. We must strictly apply fertilizer time and fertilizer amount when using it. This article tells you the correct way to use:

Fertilization time When watering and fertilizing, the temperature of the water should be as close as possible to the ground temperature and air temperature, and flooding should not be avoided. Water the greenhouse in winter, try to water in the morning; in summer, try to water in the afternoon or evening. If you don't need a dropper, try to pour as little water as possible. Flood irrigation can easily cause soil compaction, impede root respiration, affect nutrient absorption, and easily rot roots and dead trees. The promotion of "cultivation on ridges" is conducive to high crop yields.

Only scientific fertilization can obtain the ideal yield and quality of fertilizer. Scientific fertilization is not only about nutrient distribution and quality, but also scientific dosage. Generally speaking, 50% water-soluble fertilizer is used for land vegetables, and the amount per mu is about 5 kg, plus about 0.5 kg of water-soluble organic humic acid, amino acids, chitin, etc. In addition to increasing the nutrients of nitrogen, phosphorus and potassium, it can also Improve crop resistance to disease, drought, and cold resistance, and reduce the occurrence of nutrient deficiency.

Take vegetable crops such as cucumbers and tomatoes as examples. Cucumbers and tomatoes are crops that continuously bloom, bear fruit, and are harvested. According to the Ministry of Agriculture’s test, about 3 kg of nitrogen, 1 kg of phosphorus pentoxide, and oxidation are required to produce 1,000 kg of cucumbers. Potassium 2.5 kg, calcium oxide 1.5 kg, and magnesium oxide 0.5 kg.

Cucumbers, tomatoes and other crops have a larger amount of nitrogen fertilizer in the early stage of nutrient growth. Phosphorus and boron must not be lacking during flowering, and the amount of potassium and calcium should be increased in the fruiting stage, and magnesium fertilizer should be supplemented in the middle and late stages. In other words, nutrient balance should be achieved throughout the reproductive period.

In the case of mastering the nutrient balance, we must also pay attention to the combined use of water-soluble organic matter, including the use of carbon dioxide gas fertilizer.

Avoid direct flushing and take a second dilution. The amount of water-soluble fertilizer is relatively small, and direct flushing can easily cause root damage to seedlings and weak seedlings. The secondary dilution is not only conducive to uniform fertilizer application, but also improves fertilizer utilization.
