In recent years, broccoli has become a mainstream vegetable on the dinner table due to its superior taste and texture, high nutritional value, and attractive appearance, winning widespread recognition and a significant market. So, how exactly is broccoli planted? How is it maintained? Good drainage soil, sufficient sunlight, correct sowing methods, and reasonable fertilization are necessary conditions. Next, we will elaborate on these aspects from four perspectives: soil conditions, sunlight requirements, sowing methods, and fertilizer selection.
1. Soil Conditions
Broccoli prefers well-drained soil and does not require strict pH levels, with a pH of around 6 being optimal. A larger soil area with a relatively loose environment is conducive to planting. When planting, it is essential to ensure low moisture in the lower soil layer. Planting broccoli seedlings in nutrient-rich soil allows the roots to quickly adhere to the soil in the planting area, accelerating growth and ensuring better absorption of nutrients during the growth process.
2. Sunlight Requirements
Broccoli is a long-day plant. When planting broccoli, it is necessary to ensure sufficient sunlight, as long-day conditions are beneficial for photosynthesis and the accumulation of organic matter. However, during hot summers, avoid prolonged excessive exposure and provide appropriate shading to cool down.
3. Sowing Methods
Place nutrient-rich soil in a planting box and soak it with water. Use a cola bottle cap to press a hole about 1 cm deep into the soil, with a spacing of 30 cm between holes. Then, sow 2 to 3 seeds in each small hole. After sowing, cover the seeds with a thin layer of soil, water them, and wait for them to germinate. The optimal temperature for seed germination is about 25℃. Broccoli seeds usually germinate within a week. When the broccoli has grown about 5 leaves, thin the seedlings, leaving one healthy and robust seedling in each hole according to its growth potential, and remove the rest.
4. Fertilizer Selection
After one week of seedling emergence, apply seedling fertilizer. After three weeks, apply high-quality compound fertilizer, and then add another application of high-quality compound fertilizer in the fifth and seventh weeks. The amount depends on the condition of the broccoli seedlings. It is also advisable to use organic fertilizer and trace element fertilizers appropriately.
In terms of fertilizer quantity, it is also necessary to control it reasonably. Avoid over-fertilization, which can cause fertilizer damage to broccoli, and also avoid under-fertilization, which can affect the growth of broccoli.
