Cauliflower nursery suitable period in June and July, due to the early sowing time is the plum rain, in the middle and late period in the hot season, to bring cauliflower nursery. Therefore, overcoming the unfavorable factors in summer and nurturing strong seedlings are the techniques that must be mastered for cauliflower cultivation. Now we introduce the cauliflower seedling raising techniques as follows:
First, seedbed preparation
1, seedbed selection. Seedbed should be selected for its high topography, good ventilation, and good drainage. Sandy soil with loose soil and moderate fertility generally requires 16 to 20 square meters of seedbed per acre.
2, seedbed finishing. Seedbed land should be cultivated in time for drying, smashing soil blocks, picking up net weeds, and spreading 750-1000 kilograms of organic fertilizer per acre when farming.
3, seedbed settings. Two to three days before sowing, the land was leveled and made to have a wheel width of 1.3 meters, a groove width of 0.5 meters and a ditch depth of 0.4 meters.
Second, sowing requirements
1, sowing time. According to the characteristics of early, middle and late varieties of cauliflower, the early-maturing varieties were sown in the middle and late June, and the medium-late-maturing varieties were sown in late June to late July.
2, sowing method. Slip on the afternoon of the day before sowing or on the morning of the day. When planting, soak the flat bed, soak 1 gram per square meter, sow the fine earth mud after sowing. The thickness should be covered with no seeds, and then tap with a wooden board to promote soil and seed. Full contact to facilitate emergence.
3, scaffolding shade. After the seeds are sown, cover them with shading nets, insect nets or straw in time for cooling and moisturizing, and early emergence.
Third, seedbed management
1. Handle the seedlings and weeding work. Under the normal conditions of bed soil moisture can be raised 36 to 48 hours, 3 to 4 days after the Qimiao, Qimiao and time after the seedlings, weed removal.
2, do a good job at timely planting. Cauliflower false value can prevent seedlings from growing too long and promote root system development, so as to obtain seedlings of the same size, strong growth, strong resistance, and high survival rate.
3, do a good job of pest control. The most vulnerable diseases during the seedling stage are damping-off disease and blight, which can be controlled with 3% of antitoxin 250 to 300 times. The pests mainly include aphids, cabbage caterpillars, and diamondback moth, which can be used as much as 1,000% and 15% for 52% of farmland. 3500 times the control of the fight.
4, do a good job of fertilizer management. In summer, the temperature is high and the soil moisture evaporates quickly. Therefore, to keep seedbeds dry and see wet, the seedlings can be normally grown without pre-fertilization. After the survival of Cauliflora, two or three days prior Water, acre 500 kg.
