Fertilization time When watering and fertilizing, the water temperature should be as close as possible to the ground temperature and air temperature, and do not flood the water. Watering 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.
Large water flooding is easy to cause soil compaction, root system breathing is hindered, affecting nutrient absorption, and it is easy to rotten roots and dead trees. Promoting “ridge cultivation” is conducive to high crop yields.
Water soluble fertilizer can only obtain ideal yield and quality by scientific fertilization. Scientific fertilization is not only about the distribution method and quality, but also the scientific dosage.
Generally speaking, 50% of 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 matter humic acid, amino acids, chitin, etc. In addition to adding nitrogen, phosphorus and potassium nutrients, it can also Improve crop disease resistance, drought resistance, cold resistance, and reduce the occurrence of deficiency.
