In order to ensure the quality of new strawberry seedlings, four key points should be paid attention to.

In June, strawberries have entered the seedling season. In order to ensure the quality of new strawberry seedlings, we should pay attention to the following points in the process of breeding strawberry seedlings:

Strawberry seedling

First, ploughing and weeding. After the female strawberry seedlings are planted, the rainy season begins. Weeds grow vigorously during this period. Therefore, when breeding strawberry seedlings, weeding should be done well to avoid the phenomenon of grass shortage and eating seedlings.

Second, soil moisture. The propagation of strawberry seedlings is carried out by the stolon on the mother plant of strawberry. Whether the stolon can take root in time or not has a lot to do with the soil moisture in the nursery, and the moist soil is beneficial to the root system. Although strawberry breeding is in the rainy season, it is also in the high temperature season, and the soil loses water quickly. In case of continuous high temperature and less rain for more than 10 days, the soil will be dry, which is not conducive to stolon growth and binding, so it is necessary to maintain soil moisture.

Third, often remove the diseased, old and residual leaves, and remove the inflorescence on the mother plant in time. In the process of strawberry breeding, there will be old leaves, diseased leaves and so on. The emergence of these diseases, old and residual leaves will contribute to the occurrence of strawberry diseases and insect pests. If they are not removed in time, they will lead to a high incidence of diseases and insect pests in the nursery. In addition, the female strawberry seedlings will produce new inflorescences in the growth process, which consumes plant nutrients, which is not conducive to seedling reproduction, so it is removed in time to improve the reproduction rate.

Fourth, dressing up in time. Adequate nutrition helps the female parent of strawberry to reproduce continuously. In the process of breeding, it is necessary to keep topdressing to meet the nutritional needs of strawberry seedlings. Under the condition of sufficient base fertilizer, chemical fertilizer was applied twice before the end of July, the first time around July 10, the mixed fertilizer of diammonium phosphate and urea (2 ∶ 1) was 15-20 kg per mu, and the second was 15-20 kg of N: P: K (15 ∶ 15 ∶ 15) compound fertilizer per mu.
