(1) Sowing and raising seedlings. In most areas, seedlings are raised and transplanted, while in a few areas, direct seeding is the main method. When sowing seedlings in summer, attention should be paid to shading and cooling and preventing rain and waterlogging. During spring sowing, use a cold bed or hotbed to keep the seedlings warm. Higher plots should be selected to raise seedlings with high borders so that they can be drained and irrigated.

The sowing material for parsley is fruit. Because the skin is thick and hard and has oil glands, it is difficult for water to penetrate and the germination is slow and irregular, so seeds must be soaked to accelerate germination. After soaking the seeds for about 12 to 14 hours, rinse them with clean water. While washing, rub them gently with your hands to open the skin and spread them out to dry the seeds. Parsley seeds are good for light. After sowing, they should not be covered with soil, but covered with a thin layer of straw. On the one hand, it prevents water from evaporating, and on the other hand, it prevents the seeds from being washed into piles when water is poured. When the seeds germinate about 10 days after sowing, remove the grass covering. The seedlings can be divided when they have 2 to 3 true leaves, and they can be planted when they have 4 to 5 true leaves. It is necessary to sow 13 to 15 grams per 667 meters2.

(2) Field management. When planting, plant two rows in a 1-meter-wide border with a spacing of 20 to 25 centimeters. Since parsley has a growth period of 6 to 7 months, base fertilizer is very important. Apply 5,000 kg of organic fertilizer per 667 m2. In addition to organic fertilizer, 30 kg of ammonium sulfate and 30 kg of superphosphate per 667 m2 should also be applied. kilogram, potassium chloride 10 kilograms, these three kinds of fertilizers are used as base fertilizer except half of ammonium sulfate as top dressing. During the entire growth and development period of parsley, fertilizer should be applied at least 3 to 4 times.

Weeds will hinder the growth of parsley, so pay attention to regular weeding. However, parsley is a shallow-rooted vegetable and should not be cultivated too deeply, otherwise the root system of parsley will be damaged. You can also spray 25 herbicides after parsley is planted, and the dosage should not exceed 0.75 kg per 667 m2.

Maintain soil moisture appropriately to avoid dryness and water accumulation. Excessive drying of the soil often inhibits the development of parsley, slows down the growth rate, causes the stems to become hollow and bolting, affects the quality and reduces the yield; when the soil is waterlogged, the stems are prone to rot.

(3) Harvesting. When the parsley plant grows to about 15 true leaves, you can start to harvest the fresh and tender leaves that have grown in the middle of the plant in stages and in batches until they bolt and bloom in the second year. Parsley cannot survive the winter in the open field. If you want to collect seeds, you need to move the old roots into the greenhouse before freezing, and then transplant them to the open field in April of the next year.

(4) Prevention and control of pests and diseases. During the growth period of parsley, there are fewer pests and diseases. Pests include aphids, carrot flies, etc., and the main disease is leaf spot.
