Summer Cultivation and Management Technologies for Broccoli

Broccoli is also called green cauliflower。 It is introduced from abroad in recent years and as an excellent vegetable, it has more nutrition value than cauliflower, and has crisp texture and fragrant taste. Broccoli is suitable for the cold climate. Broccoli has high economic returns and short growth period (it can be harvested in 60 to 70 days after transplanting) Here are some cultivation and management technologies on broccoli.
First, select fine variety and sowing timely.
Broccoli’s optimum temperature for growth is from 16 to 22 ℃, the proper temperature during the nutrient growth is 5~35 ℃, the flower buds usually require daily average temperature is below 25 ℃. If there is high temperature (above 30 ℃) during bud development period, fast bolting, low yields, poor quality will occur. Therefore, the disease and heat resistant variety and scientific planting arrangements is the key for summer cultivation.
Second, nurture robust seedlings and timely transplant.
Summer cultivation is in a high-temperature rainy season, so nurturing the seedlings is the key.
Third, deeply plow and supply adequate basic fertilizer.
According to characteristics of broccoli, choose the fields of 800 m above sea level, and the soil is with more organic matter content and good drainage and irrigation condition, strong water and fertilizer conservation ability.
4, Plant with rational density.
Broccoli likes sunlight and moisture and dislikes hotness and waterlog. In order to improve the energy efficiency, increase soil permeability and improve microclimate of the field, rational density is very important. 5, strengthen field management
1. Reasonably topdressing is necessary after transplanting.
2. Scientific irrigation after transplanting can increase the survive rate of the seedlings. Keep the moisture content of the soil. In the frequent typhoons and storms seasons, it is necessary to drainage.
3. Loosen the soil timely and prevent the soil to harden. Increase the permeability of the soil and promote the growth of the roots. Don’t injury the roots when loosen the soil.
6, timely control the plant diseases and insect pests
7. Timely harvest
It is time to harvest when the flower ball is 12 ~ 15 cm in diameter and has fresh green color. Anti-season broccoli has shorter harvest time. So it is optimal to harvest timely and supply the markets. The time is before 9:00 A.M or after 4:00 P.M. when harvesting. Cut the follower ball with 4-5leaves and sent the fruits to the processing plants timely. (Reproduced)
