Planting conditions of broccoli

Broccoli, also known as broccoli, was introduced in the 19th century and originated in central Italy, saying that broccoli was originally adapted to grow in the Mediterranean climate. So it must have been planted in a similar climate when it was first introduced. After years of artificial cultivation, the adaptability of the variety became stronger and stronger. The planting range has also changed widely. So what are the specific requirements for the growth environment of broccoli? let's learn about it together.

1. Temperature

Strong adaptability to temperature, in the temperature of about 5 degrees can grow, that is, relatively slow, and then the higher the temperature, the faster the growth, but the temperature is too high, the quality is poor, the growth is easy to aging. So the most suitable growth temperature is 15 to 25 degrees Celsius. Germination requires a temperature of more than 20 degrees, and seedlings can grow well when they are above 15 degrees. Low temperature can complete vernalization. Broccoli is more heat-resistant and cold-resistant.

2. Humidity

In order to maintain the normal transport of nutrients and inorganic salts in broccoli, a large amount of water is needed in the process of growth. Leaves need to maintain photosynthesis, stretch and stand all need enough water, can not lack of water, short-term water shortage will reduce production. But the soil moisture should not be too high, if it is higher than 80%, it is prone to high temperature and humidity diseases such as rot. But keep the soil moisture close to 80% during the heading period.

3. Lighting

Broccoli requires a wide range of light, but it needs sunlight, like sunlight, sunlight is conducive to rosette formation, good photosynthesis, nutrients are more abundant, which is beneficial to growth and development. It can also maintain the growth potential and make the bouquet full. But the strong light is easy to burn the bouquet and get dark spots.

4. Soil nutrition

Strong adaptability to soil, as long as it is not dry land, saline-alkali land, extremely barren land can survive. But it is best to drain well, the deep soil is conducive to the absorption of nutrients, and then the soil is looser, which is conducive to rapid drainage without stagnant water. Planting is suitable for growing in neutral and acidic soil. Fertilizer base fertilizer is not too much, over-fertilizer flower moss is not tight, the need for nitrogen fertilizer is the most, potassium fertilizer is the second, phosphate fertilizer is the least. The relative increase of phosphorus and potassium after pilling. Boron, molybdenum, and other trace elements should be sprayed during the heading period.

The growth of most plants will be directly affected by the climate, determine the growth location, environment, broccoli is also according to their own growth needs to determine the environment, when the environmental conditions can be artificially controlled, in fact, it also indirectly controls the growth yield and quality.
