Parcel is an umbrella, rock wind, multi-year grass, also known as dutch scabs, scabs, scabs, occupines, and so on, most of the leaves are fragrance, salad, fruit and vegetable salad, and aroma. The following is a joint study and understanding of the methods and timing of the cultivation of the cranium。
Timing of cultivation
Arsenal is preferred for spring planting in february-march, for summer planting in june and for fall planting in late july。
Ii. Cultivation methods
1. Leaching seedlings
Pre-plant seeding is preceded by seed seeding, which occurs 12-24 hours after the seed is immersed in fresh water and in the shade, and 3-4 days after which about 80 per cent of the seed is seeded。
2. Points for planting
Slender beds should be selected in cold places, with pig and cow dung or fertilizer applied as base fats, and soil and fertilizers should be finely mixed and seeded. 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. After seeding, 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. The seedling period is two times longer and is set to be planted in the field when three or four leaves, leaving seedlings and insect-free seedlings。
Four, steady
The root of celery is shallow, and the whole ground is to be flattened, the ground is to be fined, the base fat is to be applied, and the ground is to rise. It is usually 5-6 feet wide, planted 40-50 days after seeding, with a range of 3 x 3 inches and 3-4 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
In the pre-growth period, about 10 per cent of human urine is pursued every four to five days, and in the post-growth period, fertilizer concentrations can increase to 30 to 40 per cent, with care to be taken for the application of potassium phosphorus. 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
Common diseases are morbid diseases, fungi diseases, black diseases, 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。
Overall, the market demand and prospects for celery are very good, and grower friends can do more carefully to manage their production。
