How to grow olive tree seedlings? The latest technical method tutorial

Olive is a fruit with very many uses, and its olive oil is an especially healthy type of oil, and it is very popular in our country. The olive tree has very strong growth ability and a long growth cycle, but during planting, some veteran growers, because the olive trees have been around for too long, must cultivate new trees to ensure planting benefits. So how should new trees be cultivated? Below, the editor brings you the olive tree seedling raising technology. Let's take a look!

1. Seed selection and soaking

After the fruit of old olive trees ripens, pick the fruit at the right time, pile the fruit together to rot, and once the fruit skin decays, the seeds can be taken out of the fruit. Wash off the pulp and mucilage remaining on the seeds, then select and remove shriveled seeds and seeds with pests, diseases, or wounds. Soak the normal seeds in warm water at about 35 degrees for about 2 days to promote water absorption by the seeds and increase the seed germination rate. During soaking, stir the seeds continuously and change the water appropriately to prevent the seeds from lacking oxygen, then place the seeds on a sand bed for germination.

2. Sowing and seedling raising

First, prepare the seedling bed. Olive seedlings are afraid of low temperature and water accumulation, so land preparation should be done well to improve the soil's water retention capacity and facilitate drainage. Then apply enough base fertilizer, mainly fully decomposed farmyard manure. When sowing, pay attention to the depth; just covering the seeds is enough. After sowing, water thoroughly to promote seed germination. Make sure the seed suture line is in full contact with the soil to prevent obstructing the growth of the seed radicle and germ, which could cause bending. After sowing, cover with plastic film to inhibit weed growth and prevent the soil from becoming compacted by heavy rain, which would affect seed emergence.

3. Timely transplanting

Olive has poor lateral root growth ability, so transplanting should mainly be seedling transplanting. When the seedlings break through the soil and grow to about 3 cm, carry it out. Because at this time the seeds have not fully extended, one seed can produce about 2 seedling shoots, so during transplanting, arrange them in rows to reduce planting costs. Wait until the seedlings grow 4 true leaves before arranging them in rows; this is also when the transplanting survival rate is highest. When transplanting, pay attention to planting density; it must not be too dense. Ensure sufficient growth space, which is also beneficial for management in the middle and later stages.

4. Field management

After transplanting, pay attention to observing weather changes and do good work in shading and sun protection, then before winter build a small plastic film light shed, which can both help olive seedlings overwinter and meet the light needed for growth. Under normal management, about 2 months after transplanting, the seedlings begin to take root and develop, and at this time they need certain growth nutrients. However, it should not be too much, so foliar fertilizer can be sprayed appropriately. After this, water and fertilizer work needs to be done once a month to ensure normal growth of olive seedlings and meet the water and fertilizer needs required for growth.

When transplanting, pay attention to protecting the roots of the seedlings, especially the main root, and prevent the main root from being injured. When planting, make sure the fibrous roots of the seedlings are in full contact with the soil. Then keep only about 1/3 of the true leaves. After planting, water thoroughly with settling water, which can effectively improve the survival rate. The above is a brief introduction to olive tree seedling raising technology.
