Fertilization principle
(1) Rational application of organic fertilizers, organic fertilizers and chemical fertilizers in combination; N, P and K fertilizers should follow the principles of nitrogen control, phosphorus stabilization and potassium addition.
(2) The distribution of fertilizers is based on base and chase; the top dressing is dominated by nitrogen fertilizer, and N, P, and K are reasonable; attention should be paid to the addition of calcium, boron, and other trace elements from the rosette stage to the late stage of the ball to prevent “dry burningâ€. Occurrence of other diseases.
(3) Combining high-yield and high-efficiency cultivation techniques, especially water-saving irrigation techniques, in order to give full play to the coupling effect of water and fertilizer and increase the utilization rate of fertilizers.

(3) For the more serious plots of “dry-heart burning†in previous years, pay attention to reduce the application of ammonium nitrogen or moderate calcium supplement, and apply 0.3%-0.5% calcium chloride solution from the rosette stage to the later stage. -3 times; For the boron-deficient plots, apply borax 0.5-1 kg/mu, or foliar spraying 0.2%-0.3% borax solution 2-3 times.
At the same time, 0.5% potassium dihydrogen phosphate may be sprayed for 2-3 times in combination with spraying to increase the net rate and commodity rate of cabbage.

Fertilization principle
(1) Reasonably apply organic manure, reduce the amount of nitrogen and phosphorus fertilizer, increase potash fertilizer, non-calcareous soil and acidic soil need to be supplemented with calcium, magnesium, boron and other trace elements.
(2) According to crop yields, cornices and soil fertility conditions, rational distribution of fertilizers, most of the basic phosphorus fertilizer, nitrogen and potassium topdressing; early Spring growth should not be frequently irrigated topdressing, pay attention to post-autism and mid-late-stage top-dressing, mid-late-stage top-dressing with high potassium compound Mainly fertilizer or water soluble fertilizer.
(3) Combining with high-yielding cultivation techniques, adopt the principle of “few times†and rational irrigation and fertilization.
(4) The old shed where the soil is degraded needs to be returned straw or organic fertilizer with high C/N ratio, less poultry manure, increase the number of rotations, and achieve the purpose of removing salt and reducing continuous cropping obstacles.
(5) Advocate the application of water and fertilizer integration technology to achieve water control and fertilizer control, improve quality and production, and save production costs.
Fertilization advice
(1) Maturation applies organic fertilizer, supplemented with phosphate fertilizer. After every 10 square meters of seedbed, 60-100 kg of decomposed poultry manure, 0.5-1 kg of calcium magnesium phosphate fertilizer, and 0.5 kg of potassium sulfate are sprayed according to the seedling condition. %-0.1% urea solution 1-2 times.

More than 70% of phosphorus fertilizer is used as base fertilizer (acupoint) application, and the rest is followed with compound fertilizer, 20%-30% of nitrogen and potassium fertilizer is applied, and 70%-80% is divided into 6-10 times with water during the period from anthesis to head swelling.
For topdressing, topdressing nitrogen fertilizer (N) should not exceed 5-7 kg/mu. After entering the full fruit period, the ability of the roots to absorb fertilizer can be reduced by foliar spray of 0.05%-0.1% urea, calcium nitrate, borax and other aqueous solutions, which will help delay aging, extend the harvest period and improve fruit quality.
(4) When the soil pH of the vegetable field is less than 6, the deficiency of calcium, magnesium, and boron is prone to occur. The basic application of calcium fertilizer (Ca) is 50-75 kg/mu and magnesium fertilizer (Mg) is 4-6 kg/mu. 2-3 0.1% boron concentrates.

Fertilization principle
(1) Advocate the use of high-quality organic compost, pay attention to the use of more compost with more straw and less poultry manure, implement the combination of organic and inorganic fertilizers, and return straw.
(2) Based on the soil fertility conditions and the application amount of organic fertilizers, comprehensive consideration should be given to the supply of environmental nutrients, and the amount of nitrogen, phosphorus and potassium fertilizers should be appropriately adjusted.
