Recommended heat-tolerant varieties of loose-curd cauliflower for summer

Loose-curd cauliflower, also known as loose cauliflower or green-stalk loose-curd cauliflower. It is a common vegetable on people's dining tables. Because its curd branches are relatively long and its curd layer is relatively thin, when the curd is fully expanded its form is not compact, appearing loose compared with ordinary cauliflower, hence the name. So what heat-tolerant varieties of loose-curd cauliflower are there for summer? Let's take a look together below.

Heat-tolerant variety of loose-curd cauliflower for summer: Changsheng 45-day green-stalk loose-curd cauliflower, suitable growth temperature 18-32, curd-forming temperature 22-28 degrees, early-maturing and heat-tolerant.

The per-mu yield of 90-day loose-curd cauliflower is about 2000 jin. This type of plant likes a warm and humid environment, and its drought resistance is relatively strong. For summer planting, choose a place with fertile soil, high terrain and good drainage. Its production is suited to relatively strong light; long light duration is beneficial to plant growth and can increase the plant's yield.

The early growth stage of loose-curd cauliflower coincides with the high-temperature season, and pest outbreaks are relatively serious, mainly including tobacco cutworm, beet armyworm, striped flea beetle, etc. For armyworm-type pests, use high-efficiency low-toxicity pesticides such as abamectin and Bt for control; for striped flea beetle, use acetamiprid·pyridaben for control; diseases mainly include downy mildew and black rot, etc. The former is controlled with cymoxanil·mancozeb, metalaxyl copper, etc., and the latter is controlled by spraying agricultural streptomycin, copper complex with ammonia, etc.

Through the above management measures, under a high-temperature and arid climate environment, loose-curd cauliflower can still obtain relatively high yield and excellent quality, and farmers can obtain ideal returns.
