Broccoli is not very strict with light,

But in the process of growth like plenty of light, a light foot plant growth, can form a powerful vegetation, is advantageous to the photosynthesis and the accumulation of nutrients, and make the red compaction density, fresh green color quality is good, summer sunshine is strong but also not conducive to the growth and development of broccoli.

The temperature

Within the scope of the 5-20 ℃, the higher the temperature, the faster broccoli growth.Optimum germination temperature for 20 to 25 ℃, the growth of seedling stage optimum temperature for 15-20 ℃.Broccoli has strong cold resistant and heat resistant, Indus period grow warm for 20 to 22 ℃, warm red development for 15-18 ℃, the temperature above 25 ℃ red quality variable, but as long as it is not affected by cold, red under 5 ℃ even can still be slow growth at low temperature.

Different varieties, different age of seedling of temperature requirements needed to complete the vernalization difference is bigger, so the anniversary of the cultivated varieties of choice is very important.

The moisture

Broccoli in the whole growth process of water demand is bigger, especially the red leaf vigorous growth and formation more cannot lack water, even if short-term drought, will reduce production.Seedling stage and rainy or excessive soil moisture easy cause black rot, black rot disease, etc.Red sandstone soil moisture field capacity of about 70-80% to meet the needs of the growth.

soil

Broccoli is not strict with soil conditions, but too poor, growth of plant and production quality is low, and the soil is fertile and too much can lead to flower and bud loose moss hollow.Broccoli is suitable in well irrigation and drainage, top layer deep, loose soil fertile, retention of fertility strong planted on the loam and sandy loam.To adapt to the soil PH range of 5.5 to 8, but the best for 6.Broccoli adequate fertilizer is needed in the whole growth process, the N, P, K proportion for 14:5:8.Seedling stage of nitrogen need more, after the flower bud differentiation requirements relative increase of P, K.

Pay attention to in the development process of red, broccoli of boron, molybdenum, magnesium and other trace elements or more requirement, and therefore budding before applying the appropriate microelement fertilizer will significantly improve the yield and quality.
