The cause of the second stubble of strawberry and its solution

Strawberries face more diseases and insect pests in the growing period. Only by doing a good job in pest management according to different periods can strawberries continue to blossom and bear fruit, otherwise the situation of stubble breaking will be more common. After the first harvest, there are few flowers in the second crop, and some of them do not bear fruit. What is the reason for this? Come and have a look with the editor.

The cause of the first and second stubble

1. Flower thinning and fruit thinning is unreasonable

Reasonable thinning of flowers and fruits can reduce the consumption of nutrition and promote plant growth. If you do not pick the flowers and fruits in time, it will affect the growth of strawberries, cause premature senescence and break stubble in serious cases.

2. Neglect of root system maintenance

Many growers attach importance to the management of fruit leaves and diseases, and often ignore the conservation of soil and roots. Soil hardening, acidification and salinization will cause difficulty in root respiration and weaken the absorption of fertilizer and water. On the other hand, the harvest time of strawberry is long and the root system is aging seriously, which is the main reason for premature senescence and stubble breaking.

3. Picking leaves is unreasonable.

Picking leaves during flower and fruit stage should not be too much, it should be decided by plant growth and leaf growth. When the plant grows normally and the leaf function is sound and meets its permeability requirements, leaves can not be picked. On the other hand, for the seedlings that often remove the old leaves to grow exuberantly, but those that do not remove the old leaves bloom more and more stubble, it is necessary to improve the picking of leaves to stimulate flower bud differentiation.

4. The time of withholding the shed is too early.

The flower bud differentiation of strawberry is mainly induced by low temperature. if the greenhouse is fastened too early, the temperature in the greenhouse for a long time higher than 10 degrees will result in unfavorable flower bud differentiation, but when it exceeds 25 degrees, flower bud differentiation can not be carried out regardless of the length of light.

5. Insufficient supply of fertilizer and water

After picking fruit, many friends often feel that strawberries lack nutrients and apply too much nitrogen and phosphorus fertilizer, resulting in plant prosperity, vegetative growth inhibits reproductive growth, and excessive vegetative growth will affect flower bud differentiation and form stubble.

II. Solutions

1. Reasonable thinning of flowers and fruits

According to the plant growth, reasonable flower and fruit thinning light, generally retain 5-8 fruits per inflorescence, the number of fruits should also be considered according to strawberry varieties, planting density, soil fertility and other factors.

2. Root cultivation

After entering the flowering and fruit stage, in order to ensure the development of the root system, it is necessary to carry out soil conditioning, root maintenance and root protection, and timely apply potassium fulvic acid and Milo root water-soluble fertilizer to loosen the soil, enhance soil permeability, alleviate soil consolidation and salinization, promote root system, promote flower and fruit, and increase yield.

3. Reasonable picking of leaves

The leaves of strawberries are constantly renewed throughout the year, and when it is found that the leaves begin to turn yellow and the base of the petiole begins to change color, it shows that the leaves have lost their photosynthesis and have been removed in time. In addition, for overwintering old leaves, pathogens are often parasitized, which should be removed in time after growing new leaves.

4. Strengthen the management of fertilizer and water

Strawberry is a continuous flowering crop, some plants are still expanding fruit, some are still in meetings, and some are in the period of flower bud differentiation, but when strawberries are harvested, the plant nutrients are consumed too much and their own nutrition supply is insufficient, so reasonable balanced fertilization is the key.

The above is the introduction of the causes and solutions of the second stubble of strawberries. I hope I can help you. If you want to know more about it, please follow us.
