Generally, strawberries can be controlled by pressing seedlings in early July. When the emergence rate of the seedbed reaches more than 70%, the old seedlings can be dug out, and the first generation of seedlings can continue to sprout stolons at the position of the mother seedlings. When stolons grow, the whole field can be controlled from late July to early August. When controlling strawberry growth, the application of organic fertilizer and biological fertilizer can be increased, and the use of chemical fertilizers such as nitrogen fertilizer can be reduced.

First, how to control the growth of strawberry seedlings?

1. How to control the growth of Hongyan strawberry seedlings

(1) The first control of strawberry growth should be in early July. When the emergence rate of the seedbed reaches more than 70%, the old seedlings can be dug out, and the first generation of seedlings can continue to sprout stolons at the position of the mother seedlings. When the stolons grow, the whole field is controlled from late July to early August.

(2) When controlling strawberry growth, the application of organic fertilizer and biological bacterial fertilizer can be increased, and the use of chemical fertilizers such as nitrogen fertilizer can be reduced; It can also be pruned reasonably to change the thriving trend of strawberries; If the artificial control effect is poor, triazole drugs can be sprayed.

2. The purpose of controlling strawberry prosperity.

Controlling strawberry growth can prevent diseases to some extent and promote the formation of early flower bud differentiation.

Second, when is it appropriate to press strawberry seedlings?

1, the best time for pressing strawberry seedlings

Generally, when the stolon seedlings of each level grow to 1 leaf and 1 heart, or when the stolon seedlings of the third and fourth levels grow to 1 leaf and 1 heart, strawberry seedlings can be pressed.

2. Method of pressing strawberry seedlings

(1) When pressing strawberry seedlings, it is necessary to remove the lowest leaflets first, and then fix the stolon at a distance of 2-3cm from the stolon seedlings with a seedling press, so that the rhizomes of the stolon seedlings can gently contact the soil or substrate.

(2) When pressing strawberry seedlings, the position of stolon seedlings should also be ensured. The plant spacing of stolons should be 5- 10cm, and the row spacing should be 10-20cm, so as to avoid pests and diseases caused by too dense plants and affect ventilation and light transmission.
