What to pay attention to when planting broccoli
The editor answers for netizens the questions about what to pay attention to when planting broccoli and the key points of broccoli cultivation techniques, the specific introduction is as follows:
In recent years, due to the superior taste and texture of broccoli, as well as its high nutritional value and good appearance, it has basically become a mainstream vegetable on the dining table, winning widespread recognition and a significant market. So, how exactly is broccoli planted? How to care for it? Good drainage soil, sufficient sunlight, correct seeding methods, and reasonable fertilization are necessary conditions. Next, we will elaborate on these from four aspects: soil conditions, sunlight requirements, seeding 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 and a relatively loose environment are conducive to planting. When planting, it is necessary to ensure low soil moisture levels. Planting broccoli seedlings in nutrient-rich soil allows the roots to quickly adhere to the soil in the planting area, speeding up their growth and ensuring they absorb more nutrients during the growth process, which is beneficial for their development.
2. Sunlight Requirements
Broccoli is a long-day plant. When planting broccoli, it must be ensured that it receives sufficient sunlight. Long-daylight is beneficial for photosynthesis and the accumulation of organic matter. However, during hot summers, it is also important to avoid prolonged excessive exposure and to provide appropriate shading to cool down.
3. Seeding 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, plant 2 to 3 seeds in each small hole. After planting, cover with a thin layer of soil, water, and wait for germination. The suitable 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 based on its growth potential, and remove the rest.
4. Fertilizer Selection
A week after seedlings emerge, seedling fertilizer can be applied. Three weeks later, high-quality compound fertilizer can be applied, followed by an additional application of high-quality compound fertilizer in the fifth and seventh weeks, with the amount depending on the condition of the broccoli seedlings. Organic fertilizer and trace element fertilizers should also be used appropriately.
In terms of fertilizer application, it is also important to control the amount reasonably. Avoid over-fertilization that can cause damage to the broccoli, and also avoid under-fertilization that can affect its growth.
The above sharing of the comprehensive methods for what to pay attention to when planting broccoli and the key points of broccoli cultivation techniques, hoping to act as a catalyst to solve your green plant problems.
