Technical Field
The invention relates to the technical field of strawberry planting, in particular to a strawberry greenhouse cultivation method.
Background
The strawberry planting time in China is different from morning to evening, and is earlier in the north and later in the south due to obvious difference of climates of various regions. Strawberry field planting needs to have two conditions: firstly, when the flower bud differentiation rate at the tops of strawberry seedlings reaches 50%; secondly, the ambient temperature reaches 15 to 23 ℃. Southern warm areas are generally planted from mid-9 to last 10 months. Northern areas typically range from 8 to 9 months. The planting date of partial early-maturing varieties in northern areas is preferably 9 months and 1-5 days, and the planting date of intermediate-maturing varieties is preferably 9 months and 5-10 days. However, the natural temperature of the water reaches 15-23 ℃ in both south and north. The field temperature is preferably about 20 ℃ for permanent planting, and the planting cannot be too early and too late. In the field of strawberry planting, a traditional strawberry greenhouse planting mode is adopted, and mature strawberry fruits can be supplied only from 12 months to 6 months in the next year every year. In order to break through the time limit of the fruit breaking period, the supply time limit of the strawberries is earlier to be on the market in 11 months by adopting a refrigeration seedling raising mode in the prior art. The improved seedling culture method not only meets the strong demand of the market on strawberry products in the fruit-breaking period, but also brings great industrial profit for fruit growers due to the high price and income brought into the market early. Although the existing refrigeration seedling raising mode can break through the use effect of the original strawberry supply time, the strawberry fruit supply still cannot be achieved within the period of 7-10 months.
Therefore, it is necessary to develop a strawberry greenhouse cultivation method for solving the above technical problems.
