Harvest of walnuts

After entering September, the collection and processing of walnuts has become a major task in orchard management. Premature harvesting will not only affect the reduction of walnut oil content, resulting in a decline in quality, but also cause a sharp reduction in yield; If the harvest period is too late, there will be fruit falling and animal theft, thus reducing walnut production.

The harvesting period can be based on solar terms: The white dew is the main symbolic solar term for the harvest period of walnuts. In general, the kernel weight and oil yield of the walnuts have peaked at this time. According to the appearance, nuts: When the walnut green peel from green to yellow, some of the peel on the top of the crack, full of seed, immature embryos and cotyledons become hard, at this time the flavor of the nuts, the best quality, predict the most Good harvest time.

Harvesting methods Manual harvesting is mainly suitable for the comparison of scattered or mechanically inaccessible mountain orchards by tapping walnut branches or directly shoot down the fruit with bamboo poles or long wooden poles with elasticity when the fruit is ripe. From top to bottom, hit from the inside out, so as not to damage the shoots and affect the output in the coming year. Mechanical harvesting is suitable for relatively flat and orchardized flatland orchards. The operation process is to shake the walnuts to the ground with a vibrating fruit-dropping machine, then the sweeping-collecting machine will concentrate the walnuts on the ground into strips and finally pick them up. The sorting machine picks up the box.
