How many years do the latest walnut seedlings bear fruit?

Walnuts, almonds, cashews and hazelnuts are also known as the world-famous "four dried fruits". The kernels are rich in nutrients, rich in calcium, phosphorus, iron and other trace elements necessary for the human body, as well as carotene, riboflavin and other vitamins. Walnut is a nut food loved by ordinary people and has high cultivation value. Let's take a look at the walnut sapling hanging fruit for several years.

How many years do walnut seedlings bear fruit?

Walnut usually enters the initial fruit stage after planting for 2-3 years or 5-6 years, or even 8-10 years. Early-bearing walnut and grafted walnut can bear fruit in 2-3 years, and late-bearing walnut and seed-bearing walnut take 8-10 years to bear fruit. Generally, 20-year-old walnuts enter the full fruit period, and can be maintained for about 40 years if the cultivation conditions are good. The flowering period of walnut is from April to May and the fruit ripening period is from August to September.

Growth habits of walnut trees

Walnut world is distributed in Central Asia, West Asia, South Asia and Europe. China grows in North, Northwest, Southwest, Central China, South China, East China and southern Xinjiang. It is usually born on hillsides and hills at an altitude of 400 to 1800 meters above sea level. It is often found in deep soil layers on both sides of mountain valleys. Like light, cold resistance, drought resistance, disease resistance, adapt to a variety of soil growth, like fertile and moist sandy loam, like water, fertilizer, like the sun, at the same time, the requirements of water and fertilizer are not strict, after defoliation to before germination should not be pruned, easy to produce bleeding, suitable for most land growth, like calcareous soil.

Why don't walnuts bear fruit?

The main results are as follows: 1. The planting condition of walnut seedlings is poor, the soil layer is too thin, the soil is barren, and the trees are allowed to grow without management, resulting in long-term lack of nutrition, thin branches and no flower buds, so they do not bear fruit.

2. Sufficient nitrogen fertilizer and water make the tree flourish and grow, the branches are numerous and dense, the ventilation and light transmission conditions are poor, and the growth of reproductive branches is too weak to form fruiting medium and short branches. The branches below the canopy of the walnut tree are all trimmed off, the tree is strong and weak, and the tree posture is upright, resulting in no fruit or late fruit.

3. Walnut pollination through the wind, monoecious, female flowers and male florescence are not the same, there are no other fruit-bearing walnut trees nearby, overcast and rainy days can affect pollination, resulting in no fruit or late fruit.

4. Walnut seedlings plant seeds, also known as seedling, the seedlings do not carry on the grafting of good varieties or no selection of seeds, the walnut seedlings cultivated have great differences, coupled with the influence of pollination, the advantages and disadvantages are uneven, which will lead to no fruit or late fruit.

5. Walnut seedlings are affected by diseases and insect pests, such as flower bud maggots, which only eat female flowers, which can not achieve the purpose of pollination, let alone fruit.
