Celery is a common kind of vegetable, but celery has high requirements for soil fertility. How to measure soil to suit the cultivation of celery?
Celery is an umbrella plant. There are three kinds of watercress, dry celery, and celery, which have similar functions. It is better to use dry celery for medicinal purposes. The aroma of dried agaric is more concentrated and called "pill". However, it is not a species with parsley, celery is rich in protein, carbohydrates, carotene, B vitamins, calcium, phosphorus, iron, sodium, etc. At the same time, there is Pinggan heat, expelling wind and dampness, Chufan swelling, cooling blood Hemostasis, detoxification Xuanfei, Jianweilixue, clear bowel, lungs and cough, lower blood pressure, brain sedative effect. Eating celery, especially celery leaves, is very beneficial for the prevention of hypertension, arteriosclerosis, etc., and has the role of adjuvant therapy.
Need fertilizer
Autumn sowing celery nutrient growth during the period of high nutrient absorption, this period of nitrogen, phosphorus, potassium, magnesium, calcium absorption of the five elements of the total absorption of more than 84%. The highest amount of nitrogen was required for celery, followed by calcium and potassium, and phosphorus and magnesium were the least. The celery's requirement for boron is also very large. In the absence of boron or due to drought-induced low temperature absorption, the petiole is prone to transverse cracking, ie, stem cutting disease, which seriously affects the yield and quality.
Fertilizer
The fertility of celery during the whole growth period of medium fertility level is 2500-3000 kg of farmyard fertilizer (or 350-400 kg of commodity organic fertilizer), 13-16 kg of nitrogen fertilizer, 5-6 kg of phosphate fertilizer, 6-9 kg of potassium fertilizer, and nitrogen. The potassium base fertilizer and three topdressing fertilizers were applied in a ratio of 2:3:3:2. All of the phosphate fertilizers were used as base fertilizers and fertilizers and manure (or commercial organic fertilizers) were mixed and applied.
base fertilizer
Apply 2500-3000 kg of farmyard fertilizer or 350-400 kg of commodity organic fertilizer per mu, 4-5 kg ​​of urea, 11-13 kg of diammonium phosphate, and 4-5 kg ​​of potassium sulfate.
top dressing
After easing the seedlings, the urea 6-8 kilograms and potassium sulphate 3-4 kilograms are used during the growth period of the heart; the urea 8-11 kilograms and potassium sulfate 3-5 kilograms are used in the early growth stage; Kg, potassium sulfate 3-4 kg.
Root dressing
If heart rot is found, use 0.3%~0.5% calcium nitrate or calcium chloride for foliar spray. Foliar application of boron fertilizer can avoid the occurrence of stem cracking to a certain extent, spray 0.2% borax or 40-75 kg boric acid solution per acre. Facilities can be grown with carbon dioxide gas fertilizer.
(1) Hydraulic Patient Lifting Transfer Chair is Home Care Equipment (Household Medical Equipment), it can reduce the pain of bedridden patients, maintain the patient's self-esteem, reduce the work intensity of nursing staff, and reduce psychological barriers, so that Nursing staff can then spend more time and energy caring for patients.
