How to grow the skin of the earth? How do you sow and reproduce? What are the precautions?

In front of the farmyard, there are often one or two green places, particularly green, filling the surrounding scenery with a touch of green. The green skin always brings people a sense of freshness and serenity. The small round ball is a very cute thing, so how to grow it? How do you sow and reproduce? What are the precautions?

、

First, the culture method of the skin.

1. Soil

Skin does not have high requirements for soil, like loose, fertile, humus-containing sandy soil, and good drainage of sandy soil, but can also tolerate barren and thin soil, can also tolerate alkali soil.

two。 Light and temperature

The skin likes the sunny environment, but it is also a more shade-tolerant plant.

In terms of temperature, the skin likes to be warm and is not resistant to cold. In addition, the suitable temperature for skin germination is between 10 and 20 ℃.

3. Water and fertilizer management

In the aspect of water and fertilizer management, the maintenance and management of land skin is still very simple and extensive. Basically, when planting, the soil needs to be fertilized with a certain amount of base fertilizer and watered once.

After planting, you need to apply fertilizer 2-3 times a year for the skin, of course, you can no longer apply fertilizer. Watering, although the skin can withstand drought, but still should add a certain amount of moisture, moisturizing the soil, the skin will grow well. Water is required to be watered every 7-10 days during the growing period. The soil is dry and wet to avoid stagnant water.

4. Reproduction method

The reproduction of Kochia mandshurica is generally sown and propagated, which is generally carried out in spring and sowed directly. The seeds of Kochia mandshurica are sown in April every year, and before sowing, base fertilizer is applied to keep the soil moist. Seedlings can emerge in about 10 days, and can be planted at the right time. The sowing and propagation of the skin is rapid, neat and easy to maintain.

2. Sowing and propagation methods of Kochia mandshurica

1. Ground skin seed collection

The ground skin has a certain self-sowing ability, but it can also be sown artificially. In August and September, the local skin blossoms and bears fruit, and after the fruit is ripe, seeds can be collected. Remove the fruit from the skin, remove the impurities, and let the fruit dry.

two。 The time of sowing and reproduction

If the sowing and propagation of the skin is direct sowing, it can be carried out in the first ten days of April. If the ground skin is used to raise seedlings and sow seeds, you can sow seeds from the first ten days to the middle of March and then transplant seedlings.

3. Direct sowing and propagation of Kochia barbadensis

When sowing and propagating directly, you can choose a suitable sowing place, either in the open air or in a flowerpot.

If you are sowing in the open air, you need to choose a place with plenty of sunshine, ventilation and good drainage. Sort out a suitable seedbed and add some rotten fertilizer to the soil as base fertilizer to provide adequate nutrition to the skin. Pour the arranged seedbed with water once, mix the seeds with fine sand and sprinkle them on the seedbed to ensure a suitable plant spacing. Cover the seeds with a layer of soil, the thickness of which is preferably invisible. If possible, you can change a layer of straw on top of the soil to keep the soil moist. Covered with straw, you can pour water on the straw when watering so as not to wash away the seeds. After the seeds germinate, the straw can be removed. The method of sowing and reproduction in flowerpots is actually similar, but it should be noted that the space in flowerpots is limited and the number of seeds needs to be reduced.

4. Seedling and sowing of Kochia mandshurica

In fact, raising seedlings and sowing seeds is also very simple, but it needs to be transplanted and planted when the seedlings of the skin grow true leaves.

III. Matters needing attention in skin planting

1. Insect pests in the skin of the earth and its control

In the process of growth, the skin is not easy to produce diseases, but there are still insect pests. The skin of the ground is vulnerable to aphids. When aphids are found, they can be repelled by manual catching or biological control. In addition, 1000-1200 times 40% dimethoate EC can be used to spray insect repellent, or 500 times 10% imidacloprid wettable powder solution can be used for control.

In addition to aphids, there are also green insects, which mostly occur from the end of June to the middle of August. When it is found that there are green insects, you can get rid of the insect, or you can use insecticides, using 40% dimethoate emulsion 1000-2000 times liquid or 20% Dingkang granule 4000 times solution to control.

two。 Weed control of skin of the earth

The skin is easy to be parasitized by dodder, and many other weeds will grow. When it is found that dodder or other weeds are found in the skin, they should be cleared and treated in time. Weeds can be removed by artificial control, mechanical control, chemical control, ecological control and other methods.

Artificial control mainly has two aspects. Before sowing, we should carefully check whether the seeds are mixed with weed seeds and so on, and screen them out. Secondly, when weeds are found, they will be pulled out manually. Of course, the whole process will be a little harder.

Chemical control is actually pesticides, the use of pesticides to remove horizontal weeds. At present, there are many herbicides on the market, all of which can be used to spray weeds for the skin. This will be faster, time-saving and labor-saving, but to prevent the regeneration of weeds and drug poisoning.
