Walnut seedling harvesting and packaging: Walnuts must be fully mature before they can be picked. If harvested too early, the kernel yield rate will be low, which will affect the germination of walnut seedlings for seed use, and processing will reduce the oil yield rate. According to research, the oil content of walnuts harvested in the first ten days of a month is about 10%, the oil content of walnut seedlings harvested in the first ten days of a month is about 10%, the oil content of walnut seedlings harvested in the middle of the month is about 10%, and the oil content of walnuts harvested in the first ten days of a month is about 10%. The oil content of the seedlings is about 100%, while the oil content of walnut seedlings harvested in early October is about 10%. Therefore, harvesting too late will cause the fruits to fall off easily and affect the yield of walnut seedlings that year. When the walnuts are fully mature, the characteristic feature is that the outer skin changes from green to yellow, and part of the fruit will naturally crack. At this time, it is already the harvesting period.
How to harvest walnuts: Generally use elastic wooden poles to knock them down along the branches, so as not to damage small branches, so as not to affect the growth of flower buds in the coming year. Before harvesting, the soil of walnut trees should be loosened to prevent damage to the walnut shells. Especially for thin-shelled varieties and tall walnut tree-shaped plants, loosening the soil before harvesting is even more necessary. If you are not careful, sometimes it will Damage to left and right, this cannot be ignored.
After the walnuts are harvested: You should choose a suitable site to pile up the walnuts, and then cover them with straw mats, etc. After ~ days, tap them gently with a wooden stick, and the green skin of the walnuts will fall off. Commercial walnuts sold in shells can be washed once with clean water and then dried. If the walnut kernels are used for sowing, they can be dried directly in the sun without washing with water. During the drying process, it is not advisable to be exposed to rain, otherwise the fruit will easily crack and start to rot. It is also not advisable to over-expose the walnuts to the sun, which will cause oil to form, thereby reducing the quality of the walnuts. Generally, the thickness of two layers of fruits is suitable. After turning for about a week, the membrane is easy to break and the endocarp is not easy to separate from the kernel. When the color of the cut surface of the kernel is consistent, the required drying level has been reached.
