What is the color of the broccoli stems and leaves and how the flower ball is abnormal? The color of the broccoli stems and leaves and the abnormal appearance of the flower bulbs are related to improper fertilization. Therefore, the optimization of fertilization techniques should be improved. The leaf sunscreen ensures quality. The flower ball of broccoli is white and delicate, and the consumption rate of the product is high, but it is easy to turn yellow or green purple in the hot sun, which affects the intuitive quality. In the field management, grass (such as straw) leaves or leaves should be used to cover the top to protect the flower ball to prevent inferior quality.
Specific practices to understand the characteristics of broccoli needs fertilizer. The cauliflower roots are relatively developed and require planting in soils with deep soil layers and rich organic matter. It has a large demand for nutrients, and the most needed is nitrogen and potassium fertilizer. According to research by the agricultural scientific research department, it is necessary to absorb 7.7~11 kg of nitrogen, 2.1~3.2 kg of phosphorus pentoxide and 9.2~12 kg of potassium oxide to produce 1000 kg of flower balls.
The main product organ provided by broccoli is white, milky white or green flower ball composed of hypertrophic flowering branches and flower buds. Therefore, the amount of fertilizer needed in the early stage is less. After the bud, it enters the growth period of the flower ball, and the nutrient begins to accumulate to the flower ball. The most fertilizer is needed, and sufficient nutrients must be provided. In addition to nitrogen, phosphorus and potassium fertilizers, calcium, boron and magnesium fertilizers are also required.
Apply enough base fertilizer early. Since broccoli is a favorite vegetable, it should be applied to the base fertilizer about 10 days before planting, and about 1,250 kg of organic fertilizer accumulated by the farmer, or 150-200 kg of commercial organic fertilizer, or bio-organic fertilizer. About 75 kg, with a high content of 25 kg of NPK compound fertilizer, 0.5 kg of borax or 0.4 kg of boron, only the application of full-ferment fertilizer can avoid the occurrence of deficiency.
Due to seedlings and seed dressing. Only the strong vegetative body, broccoli has a high-yield basis. Therefore, in order to make the stems, leaves and flower bulbs grow normally, it is necessary to topdress in time. After planting the seedlings, the early-maturing varieties should be chased by the mature manure 500~750 kg. , or 7.5~20 kg of ammonium sulfate, the late-maturing variety is 1,500~2000 kg of manure after being stalked and cooked.
At the beginning of flower bulb formation, urea is applied 7.5~10 kg per mu and potassium sulfate is about 5 kg. In the early stage of flower bulb formation, the boron-deficient and magnesium-deficient soil can be sprayed with 0.1%~0.2% borax solution and 0.2%~0.4% magnesium sulfate solution 1~2 times. At the same time, in the dry season, it is necessary to carry out furrow irrigation in the morning and evening, so as to adjust the water with water.
