How much is the price of white strawberries per jin in 2020

White strawberry is the "Internet celebrity upstart" in the strawberry world in recent years, and its price has always been popular. It not only has a strange and beautiful appearance, but also has a good taste. At present, its sales price is similar to that of general new varieties of strawberries, about 40-50 yuan per jin. Of course, the price of white strawberries is also different due to differences in variety and origin. For example, light snow strawberries in Japan have become a luxury, selling nine of them for 29000 yen (about 1700 yuan).

Second, the planting prospect of white strawberry

White strawberries have also been introduced and planted in China. The planting cycle is 8 months, and the average yield per mu is about 1600 kilograms. At present, the wholesale price of white strawberries on the market is 80,160 yuan / kg, which can be said to be sold at a sky-high price. In Japan, one piece is sold for 1500 yen, which translates into RMB, which is the price of more than 90 yuan each. During the holidays, it is a hot-selling product, and the supply falls short of demand, so its market prospect is very broad.

III. Planting techniques of white strawberries

1. Land selection and preparation

Strawberry orchard should be selected with sufficient light, slightly higher terrain, flat ground, convenient irrigation and drainage, fertile and loose soil, legume or onion and garlic vegetable fields for the previous crops, and weeds and underground pests should be eliminated first. It can be sprayed with 1000 times of phoxim EC (5-6 cm wet soil layer) to control grubs, mole crickets and ground tigers.

One week later, 5000 kg of high-quality rotten farm manure, 100kg of superphosphate and 50kg of potassium chloride were applied per mu. Combined with deep turning over the garden, fine ground preparation is made into a border surface with a height of 20 cm and a width of 50 cm, and the furrow is 30 cm wide. The length of the greenhouse is limited to 20 meters and there are 4 beds in it.

2. Transplanting technology

In order to get strawberries on the market from the end of January to the beginning of February, the time for strawberry seedlings in breeding nursery to be transplanted into the border of greenhouse should be in early September. To follow the seedlings, with transplanting, each row planting 2 rows, row spacing 27 cm, hole spacing 20 cm, 12000 plants per mu. When planting, the inflorescence of the same row of plants is in the same direction, so that the back of the strawberry seedling bow faces the predetermined growth direction of the inflorescence, the seedling center is exposed, the root system is flat and buried in the loose soil layer, the planting water is irrigated in time, and the exposed root is buried in the soil layer.

3. Management in the early stage of flower bud differentiation.

Strawberry seedlings transplanted in early September, in addition to timely replenishment of water, should be covered with shading net shade. The net is 1.2 meters above the ground, which is convenient for personnel to operate. It is necessary to remove withered leaves, old leaves, axillary buds and stolons in time, and keep 5-6 leaves. Flower bud differentiation needs lower temperature and short sunshine, which can be covered with grass curtains on the sunshade net. Through the operation process of uncovering and covering the grass, the conditions of short sunshine and lower temperature were artificially created to promote the differentiation of apical inflorescence and axillary inflorescence for more than a month.

4. Irrigation and drainage methods

Irrigate once at the initial stage of flowering and berry growth. It is appropriate to use furrow irrigation, so that the water irrigation to the ditch height of 2 prime 3 is better, let the water gradually seep into the border soil, and the remaining water in the ditch is discharged. If there is a drought, it should be irrigated once every 5-7 days. A section of metal pipe is put on the front end of the rubber tube for hole irrigation, which not only saves water, but also keeps the border soil loose. When it is rainy in autumn, it should be drained in time. Drainage ditches should be made early around the strawberry orchard so that the furrow water in the shed can be drained.

5. Cover with plastic film

From October to early November, it is the end of the differentiation period of strawberry inflorescence, and the sunshade net can be removed. In Jiangzhun area, "the Beginning of Winter" is covered with plastic film behind, and the plastic film in front of "heavy snow" is covered with plastic film to keep the temperature in the shed at 28-30 ℃. In the "warm winter" year, the plastic film in the middle shed was added in the "the Winter Solstice" season. The "cold winter" year should be covered with large and medium shed plastic film at the same time. In short, during the season from "Lesser Cold" to "Greater Cold", the temperature in the shed should be kept above 25 ℃, or at least 23 ℃. Only by meeting the above temperature can strawberries grow normally.

6. Ventilation operation

The soil moisture for the growth of strawberry seedlings should be 70% and 80%. The humidity of the air in the shed should be 60%, 70%, and 70%. Therefore, when the temperature in the shed exceeds 30 ℃, it should be ventilated. The plastic film at both ends of the greenhouse and the middle greenhouse should be opened for ventilation from 10:00 to 3 pm from November to December. When the humidity in the shed exceeds 70%, it should also be ventilated to reduce the humidity of the air in the shed. Keeping bees in the flowering shed, nylon wire mesh can be made at both ends of the large and medium shed to facilitate smooth ventilation. Another function of greenhouse ventilation is to control strawberry powdery mildew.

7. Harvest

Strawberry seedlings blossom, set fruit to berry coloring, soften, release unique fragrance, about 30 days. Strawberries should be harvested and listed in batches after they are ripe.

White strawberries have a unique appearance and taste and are very popular among consumers. Interested growers can try to grow them.
