1. Selection of varieties and determination of sowing period

　　Cauliflower seedsSuitable for growth in cold climate, Rugao generally can only be cultivated in autumn and winter. Cauliflower is generally used for processing and export, requiring the ball to be compact, dark green color, small grain, ripening period for middle and late ripening, high yield, relatively long harvest period, easy to arrange production in the factory. According to this requirement, in recent years, the main selection of the future, excellent and other excellent varieties of precocious, heat-resistant, transplanting to harvest between 65,175 days, in late July to early August sowing, in late August to early September planting, from the end of October to the beginning of November harvest.

2, the choice of Tian block

Choosing the field block with good irrigation and drainage conditions and the anterior stubble is not cruciferous (cabbage, vegetable, cauliflower, radish) as seedling and transplanting ground.

3. Seedling

As cauliflower seedlings in summer or early autumn, must overcome high temperature, rainy, pests and other adverse factors, so should be ventilated, well-drained, shade, anti-rainstorm facilities in the shed seedlings.

After sowing the seedbed in time to cover the film moisture conservation, the film stamped with shading net cooling, the shed covered the top film, the top film stamped with shading net, the temperature in the shed control in about 25 ℃. After sowing 2 days to check the seedling situation, when there are about 70% seedlings in the evening will be the seedbed on the film and shading net removed.

The seedbed management does not water before breaking the heart, preventing the lower embryo axis from being too high to form tall seedlings. The seedling stage does not exceed 25-30 days.

The main diseases in seedling stage are: sudden inversion disease and blight disease. The control method is after seedling arch soil

Use 75% hundred bacteria clear 500 times times liquid or 50% polymycin 500 times times liquid and other agents alternately used 2-3 times.

4, the application of foot base fertilizer, reasonable planting

Before planting each acre of rotting organic fertilizer 100-200, high concentration of compound fertilizer 50 kg, boron fertilizer 0.8 kg or so. (No boron fertilizer bulbs are easy to hollow, can also be sprayed in 10-12 leaf, exuberant growth area of the leaf). Then ploughing to do the furrow, the use of High ridge double line, the ridge width of 1.0 meters, topping 40 cm or so, mu plant 2700-3000 strains. After planting, immediately pour the definite root water.

5, Field Management

Broccoli Hi Fertilizer, staging timely fertilizer, watering is the key to quality, high yield.

Fertilizer management of the entire growth process needs adequate nutrition, especially in front of the current, the formation of enough nutrients is to seize the high yield, improve the pass rate of the key, otherwise the flower ball loose. Fertilization in principle, "light Sti seedling Fertilizer, the application of foot fat, clever application of inflated fertilizer."
