1, timely fertilizer
After the New Year, most of the strawberries have been harvested with 2 to 3 capsules. After the strawberry has been harvested for two days, it shows a simple phenomenon of de-fertilization. The primary manifestation is that the fruit shape is smaller and the quality is reduced. Production should be top-dressed in a timely manner. Potassium and potassium fertilizers should be added in a timely manner. Drip irrigation or foliar application of potassium dihydrogen phosphate, etc., can be added to increase soil fertility to promote fruit development in the middle and later stages. It is useful to increase the accumulation of sugar in strawberries and improve fruit weight and quality. The fruit is more delicious and the price of the product is higher.
As for the shooter seedlings, amino oligosaccharides or Amino Acid foliar fertilizers can be sprayed to control the growth of the strawberries and add plant resistance. At the time of spraying, the morning and dusk of a cloudy climate or a sunny day should be selected. At this moment, the temperature is low, and the leaves of the leaves are open, and the nutrition is simply absorbed.
2, reasonable water supply
During the fruit enlargement period, the amount of water required is large, and moisture is supplied in time according to the dry and wet conditions in the field. The lack of water will cause the fruit to become small and hard. If the water content is too high, it will lead to empty fruit, fruit, and other diseases. During the fruit harvesting period, it is necessary to control the water and add fruit color and sugar content. Earth-cultured strawberries are sprinkled with water 1 or 2 times a week, mixed and fertilized 1 or 2 times, and at high temperatures, watering is required 3 to 4 times a week.
3, appropriate temperature control
As the spring temperature warms up and the temperature is too high, the strawberry seedlings grow too vigorously, the fruit is too experienced and the volume is too small. The number of times the air outlet is open or the time should be added. The temperature should be reasonably controlled. During the day, the shelf temperature should be maintained at 18°C~25°C, and at night it should be 5°C~8°C.
4, attach importance to management
Weeding and weeding, adhere to the permeability of the soil, together with the late should pay attention to repair strawberry ridge, to ensure the integrity of the strawberry ridge shape. Persist in the pastoral cleanliness, bring diseased leaves and diseased fruits to the outside of the shed for destruction in time to avoid transmission of pests and diseases. Timely harvesting, harvesting and brewing of the berries is simply a matter of time, generally when the fruit is 70% colored.
5, sparse buds
The results of the first open flower of the strawberry are larger; when the flower bud is divided into the secondary order flower, it often fails to constitute an invalid flower after flowering, and even if it constitutes a fruit, it is not effective because it is too small to harvest the value. As a result, ineffective flowers, thin flower buds, small fruit, deformed fruit, and stale fruit are removed in time, and 3 to 6 fruits are kept on each inflorescence, so that nutrition is preferentially supplied to earlier buds and larger fruits to ensure that the strawberries Large, regular and easy to harvest. The fruit of sparse buds should be ruled on a few occasions and be gradually removed several times.
Proper selection of lateral buds can improve strawberry production, but too many lateral buds will result in excessive number of leaves and delicate plants. Based on the distance between the plants and the growth of the strawberries, each plant took 1~2 thick, robust and well-directed lateral buds, and other removal. The early-stemmed stolons consume a lot of nutrients and should be removed in time to maintain plant regularity and ensure nutrient supply.
6. Bee pollination
Adopting honeybee pollination is a useful way to improve the value and quality of strawberries. Periodically check the conditions of bee colonies to ensure that the water container does not cut water and avoid the bees from being water-free. If there is less honey source, you should feed sucrose or honey in time. Manipulate the temperature of the beehive to ensure that the worker bees are eager to collect pollen. When the temperature in the greenhouse is greater than 26°C, the air outlet shall be ventilated and ventilated in time, and the insect net shall be covered on the air outlet to avoid flying outside the colony.
When fighting drugs and smoking, it is necessary to move the hive out of the greenhouse. In the late stages of growing strawberries, bees were flying outside and there were a large number of deaths. Demands often checked the number of colonies and promptly made up or replaced beehives.
