How to improve quality in the middle and late stages of strawberry

1, timely topdressing

After the New Year, most of the strawberries have been harvested with 2~3 capsules. After the strawberry dime, the phenomenon of de-fertilization is simple. The first manifestation is that the fruit shape is small and the quality is degraded. Production should be timely topdressing, increase application of phosphorus and potassium fertilizer, drip irrigation or foliar application of potassium dihydrogen phosphate, etc., adding soil fertility to promote fruit development in the middle and late stages, useful to add strawberry sugar accumulation, improve fruit weight and quality, so that The fruit is more delicious and the price of the product is higher.

About the long seedlings, you can spray amino oligosaccharides or amino acid foliar fertilizers to control the growth of strawberries and add plant resistance. At the time of spraying, the morning and evening of the cloudy climate or sunny day should be selected. At this moment, the temperature is low, the stomata of the leaves are open, and the nutrition is simply absorbed.

2, reasonable water supply

During the fruit expansion period, the water needs to be large, and the water is supplied in time according to the dry and wet conditions in the field. The lack of water will cause the fruit to become smaller and harder. The excessively high water content will result in hollow fruit and rotten fruit, which will breed other diseases. During the fruit harvesting period, the water needs to be properly controlled, and the fruit color and sugar content are added. Soil-cultivated strawberries are sprinkled 1~2 times a week, mixed and fertilized 1~2 times. When the temperature is high, it needs to be sprinkled 3~4 times a week.

3, proper temperature control

Following the warming of the spring temperature, when the temperature is too high, the strawberry seedlings grow too prosperous, the fruit is too sophisticated and the volume is too small. The number or opening time of the air outlet should be added, and the temperature should be reasonably controlled. The shed temperature should be maintained at 18 ° C ~ 25 ° C during the day and 5 ° C ~ 8 ° C at night.

4, attach importance to management

Weeding and weeding, adhering to soil permeability, we should pay attention to repairing strawberry ridges in the later period to ensure the integrity of strawberry ridge shape. Adhere to the pastoral cleanliness, bring diseased leaves and diseased fruits to the outside of the shed and destroy them in time to avoid the transmission of pests and diseases. Timely harvesting, harvesting too late, simple composition of berry decay, generally began when the fruit is 70% colored.

5, sparse bud fruit

The fruit of the first open flower of strawberry is larger; when the flower bud is divided into the second-order flower, it is often impossible to form an invalid flower after flowering, even if it constitutes a fruit, it has no effect because it is too small to have harvest value. Therefore, in time, the ineffective flowers, the thin flower buds, the small fruit, the deformed fruit and the stiff fruit are removed in time, and the fruits are 3~6 on each inflorescence, so that the nutrition is preferentially supplied to the earlier flower buds and the larger fruits, ensuring the strawberries. Large, regular, and easy to harvest. The sparse buds should be gradually removed as a number of times.

Appropriate selection of lateral buds can improve strawberry yield, but excessive side buds will result in excessive number of leaves and weak plants. According to the distance between the plants and the growth of the strawberries, each plant was allowed to take 1~2 large and strong lateral buds with good direction and other removals. The early-sucking stolons will consume a lot of nutrients, and should be removed in time, adhere to plant regularity, and ensure nutrient supply.

6, bee pollination

Pollination with bees is a useful way to improve the value and quality of strawberries. Check the status of the bee colony out of time to ensure that the container of the water does not break the water, and avoid the bees being waterless. If there is less honey, you should replenish sucrose or honey in time. Control the temperature of the beehive to ensure the enthusiasm of the worker bee to collect pollen. When the temperature in the temperature room is greater than 26 °C, turn on the air outlet to ventilate in time, and cover the air outlet to prevent the bee colony from flying.

When spraying and smoking, it is necessary to move the beehives out of the greenhouse. At the end of the strawberry growth period, the bees fly outside and the number of deaths is large. The number of bees is often checked and the beehives are compensated or replaced in time.
