1, planting and sowing: cauliflower categories, from heat-resistant to cold-resistant and late-maturing varieties are very diverse, planting the right category, half the effort, this time of year planting cauliflower is generally cold-resistant categories are mainly. As for the sowing itself does not have great requirements, but in the appropriate climatic conditions sowing, need to pay attention to the density of planting, sufficient light conditions under the cauliflower increase in the strong and dense fruit.

2, pest control: cauliflower pests and diseases are common root rot, cabbage greenfly, aphids and small cabbage moths, etc., prevention and treatment is generally used in the form of crop rotation, in the successive cloudy and rainy days after the active prevention and treatment of root rot and soft rot, root rot is a common bacterial and fungal diseases, the field flushing of root polyti + flower and fruit Zan can be effective prevention and treatment.

3, scientific fertilization: adequate bottom fertilizer to ensure the healthy growth of the crop, can be mu Shi fully rotted organic fertilizer with calcium phosphate to do moisture; rosette and nodule period of full crop growth on the nutritional needs of nitrogen, phosphorus and potassium and trace elements, with the use of multi-balanced water-soluble fertilizers and in the Vizan, can play a strong plant, to promote the expansion of the flower bulb and the effect of increasing the harvest and preserving the quality of the plant.

Extended information

Cauliflower growth cycle is long, itself like fertilizer and fertilizer tolerance, the demand for fertilizer is strong, the basic requirements of fertilization management is: the application of adequate basal fertilizer, skillful application of fertilizer.

Early consumption of nitrogen fertilizer more, rosette period of nitrogen needs to reach its peak, the formation of the leaf ball needs more phosphorus and potassium fertilizer, boron, molybdenum, magnesium and other nutrients have a more special requirements, the lack of a certain element will cause lesions, such as the lack of potassium is prone to the phenomenon of black heart, lack of boron cracking at the base of the stem, the severity of the flower bulb was rusty brown, taste bitter, lack of molybdenum is dwarfed by plants, leaves long and thin.

In addition to focusing on the application of fertilizer categories, but also take into account the health of the root system and the absorption of fertilizer nutrients, the late fertilizer can be root system and foliar fertilizer synchronization, the use of water-soluble fertilizers in the Weizan, generally foliar spraying-based, the use of the concentration of 2,500-4,000 times the liquid evenly sprayed, sprinkled with drip irrigation per acre 200-500g is appropriate. -500g per mu is appropriate.
