How to grow walnuts in clay soil, and can you grow walnuts in sandy soil?

Because the sandy soil structure is loose, it retains water and has good air permeability.

Walnut trees have strong adaptability, few pests and diseases, labor-saving management, convenient fruit storage and transportation, and long life. Walnut trees like temperature and light, and have strict requirements for water, especially in the growth period of new shoots and fruit development period, which need sufficient water**, and should be planted in sandy loam soil with loose structure and good water retention and air permeability.

For transplanting large walnut trees, it is best if you can bring soil balls. If you can't bring it, try to keep the root system intact, and at the same time, cut off as many parts of the main branch and useless branches as possible, and paint the saw edge with paint.

After transplanting, the orientation of the walnut tree should be as consistent as possible.

Ask for backfill of the topsoil and allow all root systems to fully touch the soil. Then water permeable once, after the water is clear and dry, fill the void and water it once, and then cultivate the soil, the height of the soil is slightly higher than the ground level, and then remove the soil after it survives.

Be careful not to have too few roots; Be careful not to water too often.

The survival rate is close to 100%.

The larger the walnut tree, the lower the survival rate of transplanting.

We have clay soil, and I have planted two of them, but they grow very slowly.

Land selection and land preparation: hickory orchards should choose mountain plots with good site conditions, slightly acidic soil, deep soil layer, gentle slope, certain water source and convenient transportation. According to the characteristics of the growth of young hickory forests and the needs of soil and water conservation, when the afforestation land is cleared, it is better to carry out full land reclamation and land preparation.

Planting: First, the topsoil is backfilled into the planting hole, and the seedlings should be vertical, the root system should be stretched, and the depth should be appropriate. Half of the fill after pulling the seedlings and stepping on the solid, then filling the soil and stepping on the solid, and finally applying the virtual soil, to build a small mound around the newly planted seedlings, so as to avoid water accumulation around the newly planted seedlings, affecting the survival rate.

Spraying a new high-fat film on the seedling body shortens the seedling stage, quickly adapts to the new environment, and grows healthily.

Plastic pruning: The top buds of the seedlings are slightly cut off to promote their multi-branching and dwarf the tree body, so as to facilitate the manual harvesting of pecan fruits. If the branches are growing upwards, tighten the plastic rope at the ends of the branches so that the branches are always facing down.

The pulling work depends on the growth of pecan seedlings, and generally needs to be pulled for more than 2 years to ensure the controlled growth target of newly planted pecan trees.

Reasonable fertilization: Fertilization can not be applied in the year of planting, and pecans must be produced according to pollution-free standards. Therefore, the fertilization varieties should be based on organic fertilizer, pecan special organic compound fertilizer, biological fertilizer, etc., with less or no chemical fertilizer.

During the growing season, Kao 3 can transform the vegetative growth function of the plant into reproductive function. Inhibit the crazy growth of the main shoot, promote the differentiation of flower buds, more flowering and more fruit setting. At the young fruit stage, spraying the fruit pedicle to thicken the fruit pedicle to improve the amount of nutrient delivery, and cooperate with the spraying of "fruit and vegetable health care transparent coating" (the demonstration household is recruiting, please log in to the China Plant Protection Network for details) can play the role of liquid film bagging, which will not affect fruit respiration, prevent fruit rust, prevent fruit cracking, improve the coloring and brightness of the fruit surface, reduce residual toxicity and improve quality.

Pest control: common peach diseases include pecan canker, branch blight, etc. Common insect pests include pecan scales, hickory aphids, red spiders, longhorn beetles, pecan bud maggots, etc.

Rotate the spraying of a variety of targeted drugs to avoid the development of resistance. It is recommended to add a new high-lipid membrane to the targeted agent to enhance the control effect.

You can add organic fertilizer, it doesn't matter, walnuts are also barren.

Dig deep pits, apply more organic fertilizer, and strengthen water and fertilizer management in the later stage.
