Broccoli has environmental requirements, understand how to cultivate edible fungi

Light. Broccoli likes light in the growth process, but too strong is not conducive to growth and development. Temperature. In the range of 5-20 ℃, the higher the temperature, the faster the growth and development of broccoli.

1. Light. Broccoli likes light in the growth process, but too strong is not conducive to growth and development.

two。 Temperature. In the range of 5-20 ℃, the higher the temperature, the faster the growth and development of broccoli. The optimum germination temperature was 20: 25 ℃, and the optimum growth temperature at seedling stage was 15: 20 ℃.

3. Moisture. Broccoli needs more water in the whole growth process, especially in the period of vigorous leaf growth and flower head formation, even if it is short-term drought, it will reduce the yield. Rainy or high soil moisture at seedling stage can easily cause diseases such as black rot and black spot. During the period of flower head formation, the soil moisture and field capacity of 70% to 80% can meet the growth needs.

4. Soil. Broccoli is suitable for planting on loam and sandy loam with good drainage and irrigation, deep plough layer, loose and fertile soil and strong water retention. The suitable range of soil pH is 5.5-8 and 6 is the best. The demand for nitrogen is more in seedling stage, the demand for phosphorus and potassium increases after flower bud differentiation, and the demand for trace elements such as boron, molybdenum and magnesium is also more in the development of flower bulb.
