Time and method of strawberry seedling raising

In the first ten days of March, the seedbed can be turned about 30 cm deep, and then the land can be leveled and made into the shape of 1.2- 1.4 m wide, 8- 10 m long and 10 cm high. Then, cover with plastic film to keep warm and accelerate the growth and reproduction of weeds. In early April, the plastic film can be removed, and then weeds and cattail grass can be manually pulled out. At the same time, the weeding function can be carried out by mechanical means, and then the whole garden can be chemically controlled to weed. In the middle and late April, 5-7 days before the strawberry seedlings are planted, farm manure is applied at the same time, and the fertilizer is evenly spread in the 20 cm seedbed, and then the surface soil of the seedbed is cultivated as smooth and delicate as possible to prevent some pests and diseases such as cutworms and crickets and ensure the best quality of strawberries.

Third, mother plant colonization.

1. Strawberries should normally expand under the condition of new leaves from germination to the end of strawberry growth cycle. Small symmetrical leaves have normal color, thicker petiole, larger leaves, especially stable growth and high yield, and buds will appear constantly, indicating good quality. If the fruit shape and product quality meet the quality requirements of alpine strawberry, the plants can be marked to show the difference. Then, according to the characteristics of strong and developed roots, 4-5 well-developed roots and buds that are not eroded by pests and diseases are selected as the mother plants for strawberry reproduction and growth.

2. Planting time

The mother plant used for strawberry breeding is usually planted in mid-April, mainly to avoid the unfavorable growth and development of strawberries due to too dry and hot weather.

3. Planting density

666.7㎡ per mu is controlled at about 600-800 plants, and the plant spacing is controlled at about 0.5.

4. Planting standards

When planting, the depth of planting must be considered, that is to say, to meet the requirements that the depth should not exceed the buried core and the root should not be exposed at the shallowest part, this position is generally flat with the seedling heart. In this way, the roots will fully absorb water and the soil will be very full and thick. In this case, if the root is exposed, it is necessary to cover the exposed part with fine soil in time, and then water it continuously to prevent dryness. If the seedling heart is covered with too much fine soil, it should be washed with clear water immediately to avoid blocking and affecting its survival.
