Planting methods of pine nuts

Pine nut is the fruit of pine nut, and its growth cycle is relatively longer. at the same time, its use value and nutritional value are higher than that of irrigation. it can nourish yin and moisten the lungs, prolong life and treat some chronic diseases. but at present, there are still few seeds of pine nuts, and the demand for pine nuts has increased significantly in recent years, so it is necessary to increase the yield and planting area of pine nuts. Today, let's learn how to grow pine nuts.

1. Land selection and preparation

The selection of land is divided into two types, namely, the selection of seedling land and the selection of planting land. The seedling land is usually sown and raised seedlings in the sandy soil or loam soil near the water source, where the soil is relatively loose and the topography is flat, and the drainage and irrigation is good. The planting land can be planted only if the soil is rich in water, fertile soil, rich in organic matter and low soil viscosity. In the soil preparation, the soil quality of the seedling land should be fine and flat, and the planting land can be reclaimed completely or by hole reclamation, but the basic fertilizer must be well laid, which is mainly organic fertilizer or agricultural machinery fertilizer, and then supplement other micro-fertilizers according to the characteristics of the soil.

2. Sowing and raising seedlings

Before sowing, the seeds need to be put into the river sand for storage and germination, preferably indoors, and the indoor doors and windows should be closed and disinfected at the same time, so as not to affect the germination efficiency of pine nuts. Under normal circumstances, the seeds need to be germinated in the winter this year, and in the spring of the following year, the seedbed should be disinfected when sowing, and then the seeds should be sowed evenly by strip sowing. Cover with a layer of plastic film or straw to keep warm, and anything used in nursery needs to be sterilized.

3. Seedling stage management

After sowing, we should pay attention to the water management in the seedling bed and water it properly, generally sleeping and emerging about a month after sowing. During this period, we should prevent the harm of mice or birds to the seedlings. We can sprinkle some bait with medicine in the field, and spray it with carbendazim or ferrous sulfate every seven to ten days, which can enhance the immunity of the seedlings and prevent diseases at the same time. Then in the process of seedling growth, it is necessary to loosen the soil and weed many times, which can promote the growth of the seedlings, and finally when the seedlings grow to about 10 cm, they can be transplanted.

4. Reasonable close planting

Since pine nuts have to be transplanted many times before they can grow into big trees, the density of each transplant is different. In the first transplanting, the basic row only needs to be planted at a distance of 30 to 40 centimeters per row, about 30 centimeters per plant, while the second time is generally planted according to 60 centimeters in rows and 50 centimeters in trees, and the third transplanting is generally 1.5 meters in rows and one meter in trees. Each time the appropriate spacing should be increased, and the last spacing should be maintained at a distance of four to five meters and from three to four meters.

5. Field management

Because the purple potato has to be transplanted, its field management is relatively complex, including soil preparation and fertilization, topdressing and watering according to its growth, and the most basic ploughing, weeding and soil cultivation. At the same time, what we need to do is to prune and reshape the branches and leaves to ensure the growth and shape of pine nuts. As for the specific field management, you can consult. The editor won't say any more here.

6. Pest control

Aphids are the main pests of pine nuts, especially during the period of young pine trees, which not only harms the branches and leaves of pine nuts, but also directly causes death of young trees in serious cases, and often occurs in June and July in summer. we can use dimethoate EC to prevent and cure, secondly, pine nuts often have needle disease, which is different from normal needles, normal needles will not cause pine trees to be bald On the other hand, needle dropping disease will occur, and when this phenomenon occurs, we can be treated with zinc or ammonium.
