A detailed guide to pine nut cultivation methods: growing this "immortal delicacy among fruits" takes special care

Pine nuts are the seed kernels of plants in the pine family (Pinaceae), also called pine nut kernels, sea pine nuts, and so on. They have a fragrant, crisp taste and also offer good health benefits, making them an excellent food therapy product with large market demand. So, what cultivation methods are there for pine nuts? Let's take a look!

1. Site selection and land preparation

Site selection is divided into two types: the selection of the seedling site and the selection of the planting site. The seedling site is usually sown and raised in sandy soil or loam that is relatively loose, flat in terrain, well-drained and well-irrigated, and close to a water source. The planting site only needs sufficient water, fertile soil, rich organic matter, and low soil stickiness to be suitable for planting. When preparing the land, the soil of the seedling site must be finely broken up and leveled. The planting site can use full reclamation or hole reclamation, but base fertilizer must be applied well. The base fertilizer is mainly organic fertilizer or farm machinery fertilizer, and then other micro-fertilizers are supplemented according to the characteristics of the soil.

2. Sowing and seedling raising

Before sowing, the seeds need to be placed in river sand for storage and germination promotion, preferably indoors, and the indoor doors and windows should be closed. At the same time, disinfection should be carried out to avoid affecting the germination efficiency of the pine nut tree. Normally, the seeds need to be germinated in the winter of the previous year and sown in the spring of the following year. When sowing, the seedbed should be disinfected, and then the seeds should be evenly sown by drilling. Cover with a layer of plastic film or straw, etc., to keep warm. Any items used for seedling cultivation also need to be disinfected.

3. Seedling stage management

After sowing, pay attention to water management in the seedbed and water appropriately. Generally, seedlings emerge about one month after sowing. During this period, we must prevent damage to the seedlings from mice or birds. Some bait mixed with liquid medicine can be scattered in the field, and carbendazim or ferrous sulfate should be sprayed every seven to ten days. This can enhance the immunity of the seedlings and also prevent and control diseases. Then, during the growth of the seedlings, multiple rounds of loosening the soil and weeding are needed, which can promote seedling growth. Finally, when the seedlings grow to about ten cm, they can be transplanted.

4. Reasonable close planting

Because the pine nut tree must go through multiple transplants before it can grow into a large tree, the density of each transplant is somewhat different. At the first transplant, it is basically enough to plant at a distance of thirty to forty cm per row and about thirty cm per plant. At the second transplant, planting is generally done at sixty cm per row and fifty cm per plant. The third transplant is generally at one m five per row and one m per plant. Each time, the spacing should be appropriately increased. The final spacing should be maintained at four m to five m per row and three m to four m per plant for final planting.

5. Field management

Because the pine nut tree must go through many years of transplanting, its field management is relatively complex. Each time it is transplanted, the land must be prepared and fertilizer applied, and topdressing and watering should be carried out according to its growth conditions, as well as the most basic cultivating, weeding, and earthing up. At the same time, branch and leaf pruning and shaping must also be done to ensure the growth and tree shape of the pine nut tree.
