Are strawberries cool and hot?

1. Strawberries are cool fruits. Strawberry cold, sweet, sour, into the spleen, stomach, lung meridians, with heat and thirst, nourishing qi and blood, moistening lung cough, diuresis and alcohol and other effects, suitable for people with hot physique to eat.

2. Strawberries are cool fruits. Normally, eating strawberries will not cause fever, but strawberries contain a lot of sugar and plant acid, which have irritating effects on oral mucosa. In particular, it is written that the sugar content of strawberries is too high, there is no timely gargle after eating, there is a lot of sugar in the mouth for a long time, absorbing water in the oral mucosa, too much water loss of cells can lead to skin damage. After the growth of fungi, there are oral ulcers. In fact, this phenomenon has little to do with getting angry. Generally, it can be improved the next day.

What month is strawberry fruit?

Strawberry belongs to Rosaceae, strawberry genus, native to Chile. The leaves are evergreen all the year round, the flowers are white and elegant, the fragrance is pleasant, the fruit is bright red and beautiful, it is both enjoyable and edible, and the ground is suitable for pot cultivation. It is also a good product for family flower cultivation. Strawberry habits: like the sun, cold, afraid of drought, avoid stagnant water, like to grow in a humid environment and loose, fertile, well-drained sandy soil. Avoid alkaline or heavy clayey soil. In the south of the Yangtze River, young plants are cut in summer and autumn, new leaves grow in the early spring of the following year, followed by small white flowers, and the fruit can be eaten in early May. The whole cycle from flowering to fruit ripening is 30 days to 40 days.

How to cultivate high quality strawberries?

Strawberries are rich in nutrients, which are higher than apples and grapes. Strawberry in greenhouse has the advantages of easy cultivation, convenient management, low production cost, high yield and good income.

1. Cultivate strong seedlings

In the first and middle of August, strong seedlings growing on strawberry stolons were selected and transplanted to open-field nursery bed or plastic bowl to raise seedlings, which required good water retention and air permeability of seedling bed soil or bowl soil, and strawberry should be covered with sunshade net to cool down after transplantation.

2. Rational planting

The soil in the greenhouse was ploughed before planting. At the same time, 3000~4000kg and 50~60kg were used as the base, and then the border was made. The width of the border was 1 meter, and the standard greenhouse with 6 meters wide could be used as 6 beds, and the furrow was deep 25~30cm. The seedlings with normal development of new leaves, symmetrical leaflets, thick green petiole, large leaves, strong growth and good yield were selected in the middle and last ten days of September.

3. Temperature and humidity control

The temperature is generally controlled between 25-28 ℃ during the day, not more than 30 degrees, and 7 degrees at night. The early flowering stage is kept at 25 degrees, and the flowering stage is controlled at 23 degrees. Between late December and the end of January, when the greenhouse temperature is lower than 5 degrees, a small arch shed should be set up in the greenhouse, and three-layer film should be used for heat preservation at extremely low temperatures. The humidity in the greenhouse should be controlled below 80% before flowering, and 60% from flowering to fruit expansion. In order to prevent the disease of high temperature and humidity, 800 times emulsion of "New High Lipid membrane" was sprayed twice every 10 days. In April of the following year, the obvious rise in temperature can remove the membrane on both sides of the greenhouse, increase ventilation, play the role of cooling and humidity, and prolong the production period of fruit.

4. Fertilizer and water management

According to the growth of strawberries, timely supplement of phosphorus and potassium fertilizer and multiple trace elements. There should be sufficient water in the whole growth process, and the soil moisture can be slightly drier in the flowering period, and more water is needed in the strawberry growth period and berry expansion period. Irrigation can be combined with fertilization, and the fertilizer can be dissolved in water into about 1000 times solution. After the beginning of the spring of the second year, as the temperature rebounded, the production speed speeded up. In order to avoid strawberry fruit acidification, potash fertilizer should be increased by applying 0.3% potassium sulfate per mu or so. In addition, before flowering, young fruit stage and fruit expansion stage, "melon and fruit Zhuangtiling" + 0.3% Zhuangtiling urea plus 0.3% potassium dihydrogen phosphate solution was sprayed, and 0.1-0.2 kg of urea was applied to the plant to supplement the nutrients needed for fruit growth and improve the filling quality.

5. Pest control

The main diseases are aphids, leaf mites, gray mold, powdery mildew, bud blight and so on. To aphids and red spiders, it can kill 20% pyrethrin, 40% dimethoate and 1500 times. Botrytis cinerea is most likely to occur in the period of high temperature and humidity and the peak growth of strawberries, which can be controlled by 800 times with 50% Sukeling, and the effect is very good. For bud blight, pick old leaves, ventilate and penetrate light, spray 1000-fold polyoxin agent or 600-fold dimethrin aqueous solution every other week.

Greenhouse strawberries appear on the market early, and the income is very considerable. Therefore, we should strengthen the management technology of greenhouse strawberries to achieve early harvest and early benefit.
