Green Parsley Cultivation Technology

Parsley is an aphrodisiac herbaceous plant of the genus Ovrycum, which is also known as artichoke, parsley, dry celery, and citron. The color of parsley is green and has a clear fragrance. Its edible parts are young leaves and tender stems, which can be eaten raw or cooked with meat. It can also be used as a dry and fragrant seasoning for dishes or as a seasoning for soups and other vegetable foods, and has been welcomed by people.

First, biological characteristics

(a) Botanical characteristics

The height of the parsley plant is 50-60 cm, the root system is straight, and the main root is buried in 45 cm. The leaves are rooted out of three pinnate compound leaves. The leaflets are deeply nicked, the leaf edges are serrated, the petiole is 10 cm long, and the thick 0.5 In centimeters, the inflorescence is umbrella-shaped and the flower is small in color and white. It is a bisexual flower. The seeds are small and dark brown.

(B) Requirements for environmental conditions

Parsley hi warm and cool environment, growth and development temperature is 5 ~ 35 °C, the optimum temperature is 15 ~ 20 °C, more than 28 °C slow growth, long-term below -2 °C with freezing injury. The growth stage is hi moist but not stain resistant. More shade-tolerant, but sufficient light, strong growth. Wide adaptability to soil, good growth in the range of pH 6-8, more demand for nitrogen, phosphorus and potassium, more sensitive to boron, boron deficiency can cause cracking of petiole base.

(III) Growth cycle

The vegetative growth period of parsley is roughly divided into two stages.

1. Seedling stage

After sowing, the seeds were soaked in water, and they emerged at a temperature of about 25°C for 7 days. When they grew to 5-7, they became seedlings.

2. Hair growth period

After the parsley has a certain area, the heart leaves continue to grow to form a peak, the vegetative body increases rapidly, and the leaf buds on the short-thinning stems of the base gradually differentiate and draw leaves, the plants show a plexiform shape, and the absorption force is enhanced. This phase can be more than 50 in length. Leaf.

Second, species selection

The leaves of the parsley are divided into the wrinkled leaves and the flat leaves. The varieties can also be divided accordingly. The common varieties are as follows.

1. Number one celery

Introduced by Japan. Strong growth, tall plants, high yield, wide petiole, thick leaves, not easy to aging, bright green, good appearance, late bolting, strong disease resistance, easy to cultivate. Pay attention to keep the soil moist and avoid drought.

2. Blah

Introduced by Denmark. The leaves are curly black-green, good quality, and strong cold resistance. They can be harvested after sowing for about 90 days and can be harvested gradually.

3. Karelin

Introduced by Denmark. Short stems, curly leaves, long green color after ripening, high content of essential oils and dry matter, suitable for fresh-selling and quick-freezing. Easy to cultivate.

4. Worthing

Introduced by Denmark. The leaves are dark green, densely coiled, with solid stems and high yields, suitable for cultivation in hot and humid climates.

Third, cultivation techniques

(I) Cultivation season

Parsley can be cultivated in open spring and autumn. The use of protective facilities; can be cultivated throughout the year.

(B) Nursery

Firstly, prepare seedbeds to keep bed soil loose, then use 1000kg of manure and ash of Mushi, turn it evenly, and sow the seeding rate per square meter to 2 to 2.5 grams, and set 13 to 15 grams of planting per acre, after sowing. Cover thin soil. The spring sowing can be covered with a plastic film and a small shed. After the seedlings are lifted, the plastic film is peeled off. In the summer and autumn, the seedlings are shaded or shaded and used to cool and moisturize. In 5-6 leaves, it can be planted in the field. If live cultivation is used, seedlings should be seedlings.

(c) Planting and Management

1. Planting method

Planted plots should ensure that the soil is loose and free from heavy smashing. Before planting, 2000kg of pig manure was applied, 1,000kg of human and animal manure, 25kg of superphosphate, 5kg of potassium sulfate, ridged, 1.2m wide, 15cm and 20cm spacing, and 18,000 mu planting density. .

2. Fertilizer management

Planting water after planting will survive for about 3 days. After 7 days, new leaves will be sprouted to keep the soil moist and avoid drought. In the period of vigorous growth, in addition to watering, appropriate amount of fertilizer should be applied, applying 3 kg of urea per acre, and applying 0.3% of potassium dihydrogen phosphate on the leaves. After harvesting, fertilizer should be topdressed to promote growth.

3. Weeding and weeding

When the soil is compacted, it should be ploughed and weeded as soon as possible, so it should not be deep enough so as not to damage the roots. It is usually conducted after harvesting.

4. Pest Control

The disease has a spot disease, which can be controlled by 400 times solution of enzyme zinc. In the case of high temperatures and nutrient susceptibility, they are prone to physical diseases. If potassium deficiency, boron deficiency, etc., spraying 0.2% phosphoric acid: potassium dihydrogen and 0.1% borax can relieve the development of symptoms. Insect pests include aphids and carrot flies. The aphids can be killed or killed with 6000 times liquid or 2.5% Kung Fu EC 4000 times; carrot flies can be used with 20% Chrysanthemum EC 3000 times, 90% trichlorfon crystals or 80% trichlorfon 1000 times liquid powder, 50% dimethoate EC 1000 times, 25% synergistic quinolone EC 1000 times liquid to prevent rooting.

(4) Harvesting

Harvesting is generally carried out during the vigorous growth period. The method is to cut out the external growth leaves, the base leaves a petiole about 1 cm long. The harvesting standard is that when the plant has 14 green leaves or more, it can pick the middle leaf with moderate growth and good commercial character, generally 3 to 4 leaves in the middle is appropriate. Most of the base leaves are not suitable for harvesting the old leaves. The upper leaves are young, not fully stretched, and the single leaf is relatively light and the efficiency is poor. When the lower leaves are yellow and the number of green leaves is reduced, they should be collected as little as possible to increase the photosynthesis needs. The leaf area.
