First, choose a good species
Autumn delayed green cauliflower varieties can be selected for early maturing varieties suitable for autumn, such as green, green, green balls, etc., but also can choose to use late-maturing varieties, such as the Green King, Green Ridge and so on.
Second, the appropriate sowing
Delayed cultivation of autumn green vegetables, can be sown in late July to late August. The specific cultivation date and cultivar should be determined based on the time when broccoli is marketed.
Third, nurture strong seedlings
1. Preparation before nursery. After the crops have been harvested, weeds are cleared of weeds in the greenhouse and the original film of the greenhouse is retained. 7 days before sowing, Mushi 5000 tons of high-quality soil miscellaneous fertilizer, 50 kg of superphosphate, 20 kg of potassium sulfate. After fertilizing, plunge 30 centimeters deep and leave it flat. In the greenhouse, north-south direction, built 6 to 7 meters long, 1.3 to 1.6 meters wide seedbed, the seedbed soil was screened and mixed with 100 grams of carbendazim, 100 grams of trichlorfon, 100 kg of sieved high quality soil miscellaneous Fertilizer, and drenched bottom water.
2. Sowing seedlings. After soaking in the bottom water, the amount of 50-75 grams of seed sown per acre shed is used for sowing. Then cover 0.5 cm thick sieved fine soil. After sowing, cover a layer of haystacks on top of the used film on the greenhouse seedbed. Grasshoppers are covered around 10 am and uncovered at 5 pm. Cloudy weather does not cover.
3. Seedling management. When the seedlings grow to 2 leaves and 1 heart, pull out the old and weak diseased seedlings to separate the seedlings. And when the seedling grows a true leaf, it will be watered. After every 3 to 4 days, water will be poured and the seedbed will be kept moist. When the seedlings grow 4 to 5 true leaves, they are poured 2 times with large water, and then they are ready to plant seedlings. When watering, the accumulated water time should not be too long, and the amount of water should not be too large, otherwise it is prone to rot. In addition, 75% 75% chlorothalonil is sprayed every 10 days at the seedling stage to prevent the occurrence of disease.
