The Latest Methods to Improve the Survival Rate of Strawberries Transplanted in Winter
Strawberries are a fruit everyone loves. They are originally a summer fruit, but many can also be grown in winter using greenhouse techniques, which allows for higher profits. However, winter temperatures are relatively low, and many growers encounter a low survival rate when transplanting in winter, so how can the survival rate of strawberries be improved after winter transplanting? Let's take a look together.
1. Regulating temperature and humidity
Winter temperatures are relatively low, which is extremely unfavorable for strawberry transplanting, so when the nighttime temperature drops to 5 degrees, a boron cover should be promptly installed inside the greenhouse, and when the nighttime temperature drops below 0 degrees, a small hoop shed should be promptly added over the strawberry ridges. Because greenhouse-grown strawberries bloom and bear fruit continuously and in overlapping succession, after bud emergence the daytime temperature inside the greenhouse should generally be maintained at 24-28 degrees and must not exceed 30 degrees, otherwise it is unfavorable for strawberry survival.
2. Covering with film
After transplanting, after carrying out weeding and loosening the soil, hilling up around the roots, and replanting missing seedlings, black plastic film needs to be laid on the ridge surface. When laying it, first cover the ridge surface plants with the plastic film, then tear a small hole in the film, and then carefully pull the leaves out, taking care to expose the central leaves of the seedlings.
3. Tidying up the plants
After greenhouse strawberries are kept warm, plant growth accelerates, and at the same time a large number of tillers and runners will sprout. These tillers and runners should be removed in time to increase the area of the main stem and promote the timely sprouting of the terminal flower buds and the production of robust inflorescences. Generally, a single strawberry plant should retain at most 1-2 relatively robust tillers, and old leaves, declining leaves, and diseased and pest-damaged leaves should be removed in time.
4. Pest and disease control
There are many pests and diseases during the seedling stage in greenhouses. Control should be based mainly on agricultural control, with chemical control as a supplement. During cultivation, measures such as choosing varieties with strong disease resistance, cultivating virus-free strong seedlings, planting on high ridges, covering with plastic film, reasonable crop rotation, cleaning the soil, and avoiding drought and high humidity can be selected to prevent the occurrence of pests and diseases. After diseases are found, note that pesticides should not be applied before and after flowering, so as not to affect pollination and cause an increase in deformed fruit. Highly effective, low-toxicity, low-residue pesticides should be chosen.
