The celery generally refers to celery, also known as celery, which is grown over a long history, has volatile celery oil, has a strong fragrance that can boost people's appetite, and many people grow it in their homes。
Time of seeding
The celery is cold, but the seedlings are high and cold. In order to achieve high quality celery, the southern region is generally dominated by autumn seeding, which runs from january to december and supplies from october to april of the following year。
2. Methods of seeding
Pre-plant seeding is preceded by seed seeding, with seeds immersed in water for 12-24 hours in the cold and after three to four days, about 80 per cent of the seeds are seeded. Slender beds should be selected in cold places, with pig and cow dung or * manure applied as base fertilizer, and soil and fertilizers should be finely mixed and planted. The seed is covered with sifted garbage and covered with an additional layer of grass, which is removed once it is produced。
3. Shrimp management
The celery has a weak capacity to absorb water during the seeding period, and it is necessary to keep the soil moist until the seeding takes place, thus facilitating rapid seeding. When celery is sprouts, the roots are shallow and the soil is dry and wet. The urea solution is sprayed every other week to promote the growth of seedlings. Celery seedlings are grown twice between three and four leaves in the field, leaving seedlings and insect-free seedlings。
Four, steady
The root of celery is shallow, and the whole ground is to be flattened and applied to the base fat, and then to the base. It is generally 516 feet wide, planted 40-50 days after seeding, with a range of 3 x 3 inches and 3 or 4 seedlings per plant. The planting process is shallow, it is too deep to influence the growth of the root system and it is slow to grow. After planting, the root water goes down。
5. Fertilizer water management
Celery is followed up on about 10 per cent of human urine every 4 or 5 days before its growth, and by the end of its growth, the concentration of fertilizers can be increased to 30 to 40 per cent, with care to be taken for the application of potassium phosphate. Calcium phosphate was applied 20-30 kg per acre and potassium chloride was applied 20 kg per acre in the later stages of growth to meet the need for celery to grow potassium phosphate. Irrigation can be combined with fertilization to maintain soil moisture。
6. Pests and diseases
The common diseases of celery are molluscs, fungus nuclei, black rots, etc. Precaution should be observed in the planting process, in the rotation of celery on a plot of land, which is more than two years apart, and in the sterilisation of seedling beds and the cultivation of non-toxic seedlings。
The above is an introduction to the timing and methods of celery cultivation, which is rich in corrosive fibres, and which improves the gastrointestinal function. As the demand for celery increases, many areas are grown, and if there is room for home, planting is very good。
