The planting method and time of Penghao cabbage, how to grow Pengcai

To discuss the planting time of seeds, it is necessary to discuss from three aspects: suitability, flowering season and growth

1) Sowing can be carried out in spring and autumn, and spring sowing is between March and May. As for what flowers should be sown in spring and what flowers should be sown in autumn, it mainly depends on the biological characteristics of the flowers themselves, and according to their cold tolerance. Annual flowers are not hardy and adapted to spring sowing; Biennial flowers are hardy and can be sown in autumn (in the north, they must be covered with soil or moved into the sunshade for winter).

1. Planting time.

The time for planting chrysanthemum is generally spring and autumn, and since many people like to eat chrysanthemum, there are now some places that use greenhouses to grow chrysanthemum in winter. Generally, people who have eaten chrysanthemum know that it has a smell, those who like it will think it smells good, and those who don't like it will naturally feel unpleasant, so they are also selective foraging for pests, and they don't like the smell of chrysanthemum, so chrysanthemum is a very healthy vegetable to take sails.

2. Land selection and land preparation.

Artemisia chrysanthemum is suitable for the soil is relatively moist, loose and fertile land, and it is necessary to prepare the land before sowing, and fertilize the soil after the land is loosened, so as to ensure the fertility of the soil under the condition of hail.

3. Sowing method.

The most common sowing method of chrysanthemum is direct seeding in the land according to a certain density, and the second is that it can also be transplanted, that is, sprinkled with seeds on other land, and after it grows seedlings, it is planted according to a certain density.

4. Weeding and fertilizing.

When the chrysanthemum just emerges, it is necessary to start watering it, and when it grows to about 5-10 cm, it is necessary to start weeding, and the way of weeding will be pulled out according to the interval of the weeds that grow in the chrysanthemum, and at the same time, the plants with a relatively small density can be pulled out for ** or their own consumption, and the last fertilization should be carried out after weeding, so as to ensure the nutritional supply and freshness of the chrysanthemum.

5. Temperature and moisture.

Artemisia chrysanthemum is suitable for growing in a relatively warm and humid environment, so it needs to be planted in a greenhouse in spring and winter to maintain all its temperature, but when the temperature is too high, it should be turned on and ventilated in time, otherwise it will burn out. And to keep the soil moist, you basically need to water it every few days.

6. Disease prevention and harvesting.

Due to the temperature and moisture, chrysanthemum will generally get downy mildew, so it is necessary to use Plick to control it immediately, otherwise it will greatly reduce the yield. When the chrysanthemum grows to 15-20 cm, it can be harvested, and it is generally harvested every 20 days so as not to affect the quality.

Penglai pine branches and leaves are green, evergreen all year round, the shape resembles a five-needle pine, it is a good choice for interior decoration, and is loved by many people.

It is a very nutritious dish and is often compared to spinach. At the same time, many people also believe that Emperor cuisine has a variety of functions, including liver protection, diuretic, toothache, constipation, bone development, and high blood pressure. It is said that in ancient times, the emperor's dish was a tribute specially dedicated to the emperor, so it was also called a tribute dish, in addition, the emperor's dish also has many different names, such as horn cabbage, pearl cabbage, fragrant beet, etc., in fact, it refers to the same kind of dish.

The characteristic of the emperor's cuisine is that even after exposure and then soaking in water, its taste is still crisp and delicious, and the more tender the branches and leaves, the better it tastes when cooked, whether it is used to cook soup, cold salad, etc., it is very refreshing and sweet. Basil cabbage is sweet and flat, rich in vitamins, carotene and a variety of amino acids, which can nourish the heart and calm the nerves, moisten the lungs and liver, and stabilize the mood. Basil contains volatile oil with a special fragrance, which helps to clear the leader, regulate qi, eliminate food and appetize, and has the effect of lowering blood pressure and tonifying the brain.

Basil contains protein and a higher amount of sodium, potassium and other mineral salts, which can regulate the metabolism of water and fluid in the body, facilitate urination, eliminate edema, and the crude fiber contained in it helps intestinal peristalsis.

It is a very nutritious dish and is often compared to spinach.

Growth habit: like cool, humid environment, avoid high temperature and humidity. It is not very cold-tolerant, and can only overwinter in warm areas with a minimum temperature of 5 or more. Good fat. Humus-rich, loose, fertile, well-drained soil is required.

Cultivation points: propagation with cuttings. It can be carried out in spring and autumn, and the specific time is generally determined according to the flowering time requirements.

Cuttings are made in September and October, flowering on May 1st of the following year, cuttings in June and July, and flowering in early spring of the following year. Cuttings choose mature, robust shoots. At a temperature of 20-24 weeks, it takes about 2 weeks to take root.

When the seedling height is 10-15cm, it can be plucked to promote its branching. Cuttings in September can be planted in pots in November and placed in the greenhouse for maintenance. In the early stage of growth, you can apply several times of light fertilizer, and then depending on the growth situation, you can add a thicker top dressing.

After May, when the weather gets hotter and the leaves begin to turn yellow, you should gradually reduce watering and cut off the upper branches and leaves, and move them out of the house in July and August. Ground-planted plants need to pay attention to drainage and waterlogging prevention in the rainy season.

Penglai pine likes a warm and humid environment, is not cold-tolerant, and is afraid of high temperatures. The soil is preferably fertile, loose and semi-shady. Fertilize once every half a month during the growth period to keep the soil moist, but not waterlogged, the room temperature is more than 32 or the light is too strong, the leaves are easy to shoot only yellow, pruning or picking branches after timely application of envy fertilizer, in order to facilitate the germination and growth of new branches.

First of all, you have to have a premise that you have enough space in your home, and secondly, if you have one, basil needs enough hours of sunlight.

1.Fertilization of the land. It is advisable to choose neutral or slightly acidic loam with deep soil layer, loose and moist, rich organic matter, convenient drainage and irrigation, and good water and fertility retention.

Before sowing, the soil was turned deeply, and 1000 kg of decomposed manure was applied per mu. Made into a wide meter of high compartment Artemisia chrysanthemum, the depth of the furrow is 20-25 cm.

2.Cultivation season. It can be cultivated in Shandong Province all year round, and facilities are required for cultivation in autumn and winter. It generally takes 30-60 days from sowing to harvesting.

3.Sow. Artemisia chrysanthemum plants are small and have a short growth period, which can be intercropped with other vegetables.

In production, live broadcast is mostly used, and both spreading and stripping can be used. Seeding per mu with 4 5 kg. Strip sowing is 2 kg per mu with a row spacing of 10 cm.

In order to promote the emergence of seedlings, soak the seeds in warm water of 30 35 for 24 hours before sowing, remove them after washing and put them under the condition of 15 20 to promote germination, rinse with water every day, and sow seeds when the seeds are white after 3 4 days. In spring, sowing is selected on a sunny day, covered with film after sowing, and the water is properly controlled after the emergence of seedlings, and the appropriate temperature is maintained to promote the healthy growth of seedlings. The temperature is high in summer and autumn, and after sowing, it should be covered with shade omentum and other mulch to keep the soil moist.

The seedling stage should be timely to ensure that the seedling has a certain nutrient area.

4.Field management. Keep the soil moist after sowing and before emergence, and the seedlings can be ready in 6 to 7 days.

After sowing seedlings in winter and spring, watering should be properly controlled, and seedlings should be thinned when 2 or 3 true leaves. sown, Artemisia macrophylla 6 cm square to leave strong seedlings, medium or fine-leaved Artemisia chrysanthemum 3 4 cm square seedlings; For strip sowing, the plant spacing of Artemisia macrophylla is 5 cm, the distance between the plants of Artemisia mesophylla is 4 cm, and the distance between the plants of Artemisia sylvestris is 3 cm. Adequate water supply to keep the soil moist.

When the plant height is about 10 cm, chase 1 2 times of fast-acting nitrogen fertilizer with water, and start harvesting when the plant height is about 20 cm. After the first cut, water and top dressing to promote the occurrence of side branches, and harvest after 20 to 30 days. 500 kg of manure and 3 4 kg of urea are applied to each mu.

5.Pest and disease control. Disease.

The main diseases are blight, leaf spot and sclerotinia sclerotinia and so on. To prevent and control blight, the focus should be on strengthening comprehensive agricultural prevention and control measures, and attention should be paid to sowing at the appropriate time to prevent over-sowing and seedlings from growing; Pharmaceutical prevention and control can use chlorothalonil wettable powder. In the prevention and control of leaf spot disease, crop rotation should be implemented and field management should be strengthened.

Pest. The main insect pests are vegetable borer, aphids, etc., and the control methods are the same as those for cultivated vegetables, but it is necessary to avoid the application of high and toxic pesticides.

6.Harvest at the right time. It can be harvested when the plant is 20 cm tall. Leave 2 or 3 leaves at the base of the stem to be cut off to promote lateral branching.
