Organic cauliflower growth optimal temperature: different varieties of growth optimal temperature is different. Early-maturing varieties of growth temperature of 16 degrees Celsius to 30 degrees Celsius, medium-maturing varieties of 12 degrees Celsius to 25 degrees Celsius, late-maturing varieties of 8 degrees Celsius to 25 degrees Celsius. Different varieties of organic cauliflower on the temperature of different adaptability, the longer the growing period is more resistant to low temperatures, a short growing period of heat resistance, excellent varieties of temperature difference to adapt to a greater range of temperature, temperature sudden change in the case of the flower bulb less impact.

The so-called organic cauliflower is not a variety of cauliflower, but the requirements of the vegetable planting environment, not to say that the growth of fluffy organic cauliflower, compact is not, but as long as the planting environment can meet the organic standards, can be called organic cauliflower.

Cultivation techniques for cauliflower

1, selecting the land rectification

Planting cauliflower, pay attention to the selection of fertilizer, loose, well-drained sandy loam for planting, rectifying the land, to be applied into the adequate base fertilizer, and digging a good planting hole, watering the soil wet.

2, sowing

Cauliflower is like cold vegetables, but the temperature can not be too low, will inhibit the germination of cauliflower, it is recommended that the spring of each year in February-April for sowing, sowing should pay attention to the density of the soil, according to the soil moisture for a reasonable sowing, but also in the sowing of the seeds before the seeding of seed mixing, to be able to increase the ability of cauliflower to resist disease. The seeds can also be mixed before sowing, which can improve the resistance of cauliflower to disease.

3, transplanted on schedule

Because the temperature in early spring is still relatively low, so the growth of cauliflower in the planting will be relatively slow, usually 45-60 days, when the seedlings grow 3-6 leaves, you can planting transplanting. When transplanting, pay attention to the leveling of the field as well as reasonable spacing.

4, water and fertilizer management

After planting a good cauliflower, pay attention to good water and fertilizer management, keep the field moist, in the application of sufficient basal fertilizer, you need to apply seedling promotion fertilizer to urea and potash fertilizer, to promote the growth of lotus leaves. Apparent buds after the application of potassium sulfate-type compound fertilizer, after the beginning of the ball picking after the application of potassium sulfate-type compound fertilizer, pay attention to boron and molybdenum trace elements in the formation of leaf ball supplementation, foliar spraying of potassium phosphate, boron fertilizer, molybdenum fertilizer.

5, artificial pollination

Artificial pollination should be carried out after the flowering of cauliflower, picking the day of the opening of the male flowers, and then gently wipe the stigma of the pistil, but also the use of pollen liquid spray pollination, flowering, but also sprayed with 2% of the saline water to increase the yield of seeds.
