Cauliflower has relatively strict requirements on humidity. The soil moisture is 70% to 80% and the relative humidity is 80% to 90%. The adaptability to the soil is strong, but the sandy loam rich in organic matter and water retention is the best. The suitable range of soil pH is pH 5.5-6.6. Here is the introduction of water and fertilizer technology for broccoli cultivation. Cauliflower grows for a long period of time and has a large demand for nutrients. According to the research, for every 1,000 kilograms of flower bulbs produced, it is necessary to absorb 7.7-10.8 kg of pure nitrogen, 2.1-3.2 kg of phosphorus pentoxide, and 9.2-12.0 kg of potassium oxide in a ratio of 1:0.3:1.1. Among them, nitrogen and potassium are the most important ones, especially when the leaf clusters are growing vigorously, and more nitrogen fertilizers are needed. During the formation of flower bulbs, more phosphorus is needed. Before budding, we must ensure adequate supply of phosphorus and potassium nutrition. In addition, certain amounts of trace elements such as boron, magnesium, calcium, molybdenum, etc. are required for the growth of broccoli. Therefore, on the basis of ensuring the supply of N, P and K fertilizers, the supply of trace elements should be strengthened. 1. Prevent boron and magnesium deficiency. Cauliflower is sensitive to elements such as boron and magnesium. When it is deficient in boron, it causes the center of the flower stem to crack, and the flower ball appears brown with a bitter taste. In the absence of magnesium, the leaves curl and the growth is slow. 2. Formulated fertilization. Mainly organic fertilizer, supplemented by chemical fertilizers and trace element fertilizers, vigorously strengthen formula fertilization. Top dressing should focus on nitrogen fertilizer for leaf fertilizer, phosphate fertilizer for fruit fertilizer, and potash fertilizer for root fertilizer. If only one fertilizer is used, the overall growth of broccoli will be adversely affected. The timely spraying of strong stalks made the stems of the plants stout and flourished. At the same time, it can increase the ability to resist disasters, reduce the amount of pesticides and fertilizers, and reduce residual poisons. 3. Scientific nitrogen application. When broccoli lacks nitrogen fertilizer, the stems and leaves of the plants are narrow and the color of the leaves is yellow, and the yield and quality are reduced. When the nitrogen fertilizer is sufficient, the plants grow lushly, the leaves are dark green and high in yield. However, over-application of nitrogen fertilizer can also lead to a dramatic increase in nitrate content in the vegetables, which is prone to pests and diseases. In addition, the last topdressing of broccoli with nitrogen fertilizer until the product is marketed must have a safe interval, and should be available on the eighth day after the last application of nitrogen fertilizer.
