The difference between greenhouse nectarines and ordinary peaches

Everyone knows that nectarines are delicious fruits, but do you know the difference between greenhouse nectarines and ordinary peaches ? Let me introduce it to you.

Introduction

Nectarine is a variant of common peach (with fuzzy skin ). There are wild nectarines in the northwest of China, which are called "Li Guang peaches" locally. Its adaptability to soil and climate and its cultivation techniques are basically the same as those of common peaches. Nectarine production in China started late. Early varieties were mostly introduced from Europe and the United States, and tasted sour. Because they did not conform to the consumption habits of Oriental people, their impact on production was limited, and people were left with the impression that "nectarines are sour."

The difference from ordinary peaches

1. The skin of nectarine is hairless, smooth, shiny, and brightly colored, as if it were coated with oil; the skin of ordinary peaches is fuzzy, reddish or slightly yellowish, and not shiny.

2. The skin of nectarine is difficult to peel; the skin of ordinary peaches can be peeled when they are ripe.

3. The flesh of nectarine is crisp and contains relatively less water ; ordinary peaches are crisp when raw, and become soft and contain a lot of water when ripe.

4. Nectarines are available earlier; regular peaches are available a little later. However, because different varieties of regular peaches mature at different times, they can be sold from early summer to late autumn.

Nutritional value of Dapeng nectarine

Nectarines are rich in vitamin C. Nectarines are cultivated from peaches. They are sweeter than peaches and more nutritious. The vitamin C contained in a fresh nectarine can almost meet the daily needs of an adult. Vitamin C not only helps the body absorb iron and maintain the immune system, but is also essential for the synthesis of collagen, an important component of the skin. Collagen can also promote wound scarring and is very important for wound healing. The skin of nectarines is smoother than that of peaches, without the annoying fuzz. The flesh is harder and comes in pink, yellow, and white colors, and has a stronger fragrance than nectarines. Nectarines contain slightly more calories than peaches, with an average of 36 calories.

How to eat and taboos

There are many ways to eat nectarines. They can be eaten fresh. Since they are not easy to preserve, they can also be processed into canned peaches, dried peaches, peach preserves, peach jam, fruit wine, juice, etc.

(1) Although nectarines are delicious, you should not eat too many of them. Li Shizhen once said: "Eating too many raw peaches will make you bloated and cause boils , which is harmful rather than beneficial." The saying "peaches nourish people" means that peaches should be eaten in moderation, but fresh peaches should not be stored.

(2) Eating too many nectarines can easily cause internal heat, so people with excessive internal heat and prone to boils should not eat too many nectarines. However, eating preserved fruits does not have this disadvantage.

(3) Although peach kernels have the effects of breaking blood stasis, removing blood stasis, and promoting bowel movements, they contain volatile oils and a large amount of fatty oils, which have more laxative effects than tonifying effects. Therefore, do not eat too much of them. Eating too much of them can lead to poisoning. In the early stages, there will be symptoms such as nausea, vomiting, headache, dizziness, blurred vision, and accelerated heartbeat. In severe cases, it can lead to cardiac arrest. Pregnant women should especially avoid eating them.

Cultivation knowledge

Soil management

The purpose is to create a deep, loose, nutrient-rich soil environment for the root system . Before building the garden, deep plowing and fertilization should be carried out or the soil should be dug and concentrated for fertilization first, and then the hole should be gradually expanded in combination with autumn basal fertilizer . Intertillage and weeding. Nectarines have a well-developed root system and require good ventilation conditions. Multiple intertillage and weeding should be carried out during the growing season to ensure that the surface is loose, which is conducive to the rapid growth of nectarines. Reasonable intercropping. In order to improve the light, heat, water and air resources of the land, the nursery can be intercropped appropriately, but green manure, melons, vegetables, beans and other low-stem and short-crowned crops that do not affect growth and development, do not spread related diseases and pests, and do not compete with the trees for fertilizer and water.

Fertilization

The basal fertilizer is mainly farmyard manure supplemented with superphosphate . Starting from the second year after planting, 150-200 kg of basal fertilizer should be applied per plant each year; for young trees (2-4 years old), nitrogen fertilizer is mainly used, 1-4 kg per plant per year, with appropriate amounts of phosphorus and potassium. When entering the fruiting period, the ratio of nitrogen, phosphorus and potassium should be increased year by year, generally requiring 2:3:2, and other trace elements should be appropriately supplemented.

Watering

Areas with annual rainfall of more than 500 mm do not need to be irrigated, but in areas with relatively dry spring, in order to ensure normal development or avoid damage from late frost, it is required to irrigate once during the germination period after thawing and once before freezing.

Plastic pruning

The apex dominance of the nectarine tree is relatively strong, with many branches, fast growth of new shoots, and easy formation of flower buds. It is important to cultivate a high-yield tree shape early. The commonly used shapes are the natural open-heart shape with three main branches and the open-heart shape with two main branches, as well as the short and close-range layered shape. However, it should be flexibly controlled according to the cultivation method and density.

Health Benefits

1. Nectarines have the effect of replenishing qi and blood, nourishing yin and promoting body fluid. They are especially suitable for people who have just recovered from a serious illness, have qi and blood deficiency, sallow complexion, thin muscles, palpitations and shortness of breath.

2. Nectarines have a high iron content, making them an ideal supplementary food for patients with iron deficiency anemia. In addition, nectarines are high in potassium and low in sodium, making them suitable for patients with edema.

3. Peach kernel extract has anticoagulant effect, can inhibit the cough center and stop coughing, and can also lower blood pressure, so it can be used as an auxiliary treatment for patients with hypertension. In addition, peach kernel has the effect of promoting blood circulation and removing blood stasis, moistening the intestines and relieving constipation, so it can be used as an auxiliary treatment for amenorrhea, traumatic injury, etc.

Storage method

Store the nectarines at room temperature. You can also put them in a fresh-keeping bag, seal them, and then refrigerate them.

Food precautions

1. Nectarines are especially suitable for the elderly who are weak, have dry intestines and constipation, are thin, and have yang deficiency and kidney deficiency.

2. People with excessive internal heat, prone to boils, and diabetes should not eat too many nectarines. Infants, diabetics, pregnant women, and those with heavy menstruation should avoid eating nectarines.

Now everyone understands the difference between greenhouse nectarines and ordinary peaches.
