What is the planting method and time of herbaceous peanut? What are the nutritional values?

Peanut is a leguminous crop, one of the main varieties of high-quality edible oil, also known as "peanut" or "everlasting fruit". Peanut is an annual herb. So do you know the planting method and time of peanuts? What are the nutritional values?

I. planting methods of peanuts

1. Sowing methods the sowing methods of peanuts are sown in the open field and covered with plastic film according to the cultivation method. According to the mode of operation, it is divided into manual on demand and mechanical sowing.

2. The principle of reasonable close planting should be grasped in sowing density. The planting density of peanut is determined by plant height, fruiting range and leaf area. The suitable planting density of peanut depends on climate characteristics, soil fertility, selection of varieties and cultivation conditions.

According to the soil fertility of peanuts in various places, the plant row spacing is 5 × 8 inch, double kernel planting, sowing basic seedlings per mu is more than 23000, and the number of harvested seedlings is about 20, 000. CDB tries to use peanut specifications for ploughing or peanut burrowing apparatus, with six rows per row.

Planting method of peanut and the best sowing time of peanut

3. The sowing depth of peanuts should be about 5 cm. It is necessary to grasp the principle of "dry is not deep, wet is not shallow" and the soil should be shallow and sandy land or sandy land should be deep. The deepest cultivation in the open field should not exceed 7 cm, and the shallowest should not be less than 3 cm.

4. Suppression after sowing is a successful experience of drought-resistant sowing to ensure the whole seedling of peanut. After suppression, it can not only reduce soil water evaporation, but also make seeds in close contact with soil, promote the rise of soil moisture, prevent seeds from drying, and facilitate seed germination.

Second, the best planting time for peanuts

General peanut sowing period: when peanuts sow, the soil temperature 10 cm deep can be sown when the soil temperature is stable above 15 degrees for 5 days. Remember that when the temperature is below 11 degrees Celsius, do not sow seeds to prevent the emergence of rotten seeds and dead seedlings, that is, peanuts can be unearthed. Peanut seedlings are not strong enough to affect yield. In general, the best planting time of peanut is from mid-late April to early May, and plastic film mulching can be advanced to mid-late March.

The peanuts with shells should be dried 2-3 days before sowing, peeled after drying, mixed with 50% imidacloprid suspension seed coating agent and gold suspension seed coating agent, and sown after drying. Sow 2-3 seeds in each hole, the sowing depth is 1.5 inches, the soil with good clay and soil moisture can be shallower, and the soil with sandy soil and poor soil moisture can be deeper. It is suggested that spring peanut planting areas should be covered with plastic film, which can be sowed early to increase peanut yield.

Summer peanut planting areas can choose interplanting, sowing in advance to increase yield. In general, the best planting time for peanuts is mid-to-late May. The most suitable sowing time in Jiaodong area is from late April to May 1. When sowing peanuts, the soil temperature at a depth of 10 centimeters must reach 11.5 to 13 degrees. Remember not to sow when the temperature is below 11 degrees, so as to prevent the occurrence of rotten seeds and dead seedlings. Even if peanuts can be unearthed, peanut seedlings are not strong enough to affect yield.

Mastering the planting method and the best planting time of peanut can not only prevent the problems caused by sowing, but also effectively increase the yield of peanut. Here, the editor would also like to remind you that due to the changeable weather recently, we must deal with it according to the climate when sowing.

III. Nutritional value of peanuts

1. Improve intelligence and memory

Peanut protein contains more than ten kinds of amino acids needed by the human body, among which lysine can improve children's intelligence, glutamate and aspartic acid can promote cell development and enhance brain memory.

2. Promote the growth and development of human body.

The content of calcium in peanuts is very high, and calcium is the main component of human bones, so eating peanuts can promote the growth and development of human body.

3. Coagulation and hemostasis

Peanut clothing contains oil and a variety of vitamins, and contains substances that shorten the clotting time, can resist the dissolution of fibrin, promote the function of bone marrow to produce platelets, and not only has the effect of hemostasis for a variety of hemorrhagic diseases, but also has a certain therapeutic effect on the primary disease, which is beneficial to the hematopoietic function of the human body.

4. Moistening the lung and relieving cough

Peanuts are rich in fatty oil, which can play the role of moistening the lungs and relieving cough. it is often used for chronic cough and asthma, expectoration with blood and other diseases.

5. Nourishing blood and dredging milk

Peanuts are rich in fatty oil and protein, which can nourish qi and blood, nourish blood and clear milk for those with insufficient postpartum milk.

6. Anti-aging

The catechin contained in peanuts has a strong anti-aging effect on the human body, and lysine is also an important component to prevent premature aging. Often eating peanuts is beneficial to the human body to delay aging, so peanuts are also known as "everlasting fruit".

7. Prevention of coronary heart disease

Peanut oil contains a large amount of linoleic acid, which breaks down cholesterol in the body into bile acid and excretes it. Avoid cholesterol deposition in the body, reduce the risk of high cholesterol, can prevent coronary heart disease and arteriosclerosis.

8. Prevention of colorectal cancer

When the soluble fiber in peanut fiber tissue is digested and absorbed by the human body, it absorbs liquids and other substances like a sponge, and then expands into a tape body that is excreted in the feces. When these objects pass through the intestines, they come into contact with many harmful substances and absorb some toxins, thus reducing the accumulation and toxicity of harmful substances in the body and reducing the chance of bowel cancer.
