What is the utilization value of Phytolacca acinosa? How do you breed? Common pest control?

Pokeweed (PhytolaccaacinosaRoxb) is a sturdy perennial herb of Phytolacca, so what is the utilization value of Phytolacca? How do you breed? Common pest control? It is understood that as a green manure in fertile fields, Phytolacca is very rich in nitrogen, phosphorus and potassium, and its fertilizer effect is very significant. production practice has proved that the fertilizer effect of Phytolacca is better than that of other grasses and leaves, on the one hand, it has more nutrients than Phytolacca itself. on the other hand, it is because the stems and leaves of commercial land are delicate, easy to decompose, and easy to be absorbed and utilized by crops.

What is the use value of Phytolacca?

1. The green manure value of Phytolacca acinosa

As the green manure of fertilizer field, Phytolacca is rich in nitrogen, phosphorus and potassium, and the fertilizer effect is very significant. the production practice has proved that the fertilizer effect of Phytolacca is better than that of other grasses and leaves, on the one hand, it has more nutrients than Phytolacca itself. on the other hand, it is because the stems and leaves of Phytolacca acinosa are delicate, easy to decompose, and easy to be absorbed and utilized by crops.

2. The manganese accumulation value of Phytolacca acinosa

Soil heavy metals are the focus of attention in recent years, heavy metal pollution has a significant impact on the environment and human health, among which manganese is one of the important research objects. The accumulation of manganese in the soil is non-degradable, which makes the treatment more difficult. At present, some investigations have proved that Phytolacca can obviously enrich manganese and can effectively reduce the content of manganese in soil.

3. The bio-pesticide value of Phytolacca acinosa

It is reported that the dried Phytolacca fruit can be ground into dry powder and sprinkled in water to kill snails with Schistosoma japonicum, and its efficacy is not easily disturbed by the external environment, and its toxicity to mammals is also very low, so it is a very safe biological pesticide.

4. Edible value of Phytolacca

At present, there are two kinds of Phytolacca acinosa distributed in China, one kind of stem is purplish red, this kind of pokeweed is poisonous and cannot be eaten, and the other kind of stem is green. This kind of Phytolacca seedlings is edible and is a kind of high-quality wild vegetables. the buds germinated in the following spring can be eaten.

5. The ecological value of Phytolacca.

The root of Phytolacca acinosa is fleshy, the root distribution is deep and wide, and the effect of soil fixation is very significant. the aboveground part of Shang land grows and propagates rapidly, and the effect of water and soil conservation is strong.

Second, how to reproduce?

The propagation mode of Phytolacca can be divided into seed propagation and fleshy root colonization. And the way of reproduction is very simple.

Seed propagation

The sowing time can be fixed in February of each year. Because of the function of soil and water conservation, a small shallow trench can be dug on the wall of the terrace and planted, with eight to ten seeds in each shallow trench. Then cover with a layer of soil, it is also said that covered with charred plaster, the effect will be better. When the seedlings emerge one after another, in each pile of seedlings, choose to keep the robust seedlings that grow, and pull out the rest. After the seedlings grow to 10 centimeters, choose cloudy days or sunshine is not enough time for transplanting.

Fleshy root colonization

The best time for fleshy root colonization is from mid-November to mid-December. Select the place where the root has buds to cut the skin, then apply plant ash, sow, and finally cover the top with a layer of 3-4 cm of soil, and then apply high-quality agricultural fertilizer. Pay attention to proper watering.

Third, prevention and control of common diseases and pests?

1. Phytolacca aphids and their control.

Aphids, commonly known as "putty", like to suck juice in young parts of plants and also like to "eat" bugs. Aphids come in many colors, but our most common ones are green. The leaves of plants damaged by aphids are prone to yellowing and are easy to be accompanied by coal fouling disease.

Control measures of Phytolacca acinosa aphid

If there is an outbreak of aphids, 1000 times diluted aldicarb and aldicarb can be sprayed every other week. If there are few aphids, you can use a brush to sweep away bugs.

2. Phytolacca acuminata and its control.

Commonly known as "Xiao Hei Fei", the plants harmed by it will be depressed, their immunity will decline, and they will even be susceptible to fungi, followed by other diseases such as red star disease.

Control measures of Phytolacca acuminata

In the process of Phytolacca cultivation, it is necessary to ensure that the cultivation medium is as transparent as possible, can be mixed with gravel, add less peat or soil, usually try to keep the soil in a dry state, not long-term moisture.

3. Phytolacca root rot and its control.

As the name implies, root rot is caused by the infection of bacteria, the ability of the plant to absorb water and nutrients is weakened, and the aboveground part of the damaged plant withered and withered, which will eventually cause the death of the whole plant.

Control measures of Phytolacca root rot

Select good drainage plots for planting; timely drainage in the rainy season; if necessary, pentachloronitrobenzene can be used for soil disinfection.
