"Snow White" strawberries are so expensive, but the planting method is not much different from other varieties!

Friends who like to eat strawberries should have heard of "Snow White" strawberries. "Snow White" strawberries are as beautiful as their name, not only with high ornamental value, but also with a very good taste. And it has high economic value, and it is an excellent variety that many strawberry growers want to choose. "Snow White" strawberry is a new strawberry variety selected from the mutant of tissue culture plantlets. Let's learn its planting techniques.

First, planting time

In order to be able to sell at the best time, it is best to start the management of the early stage of flower bud differentiation in September. 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 terminal inflorescence and axillary inflorescence.

II. Irrigation management

Water was irrigated once at the initial stage of flowering and berry growth. It is best to use ditch 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.

Third, 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.

IV. 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, at the same time can control strawberry powdery mildew.
