When it comes to vegetables, whether it is in the countryside or in the city, this vegetable is indispensable. It is a green onion. For the southerners, the green onions are usually grown in small amounts, and the green onions are also less, but in the north, before winter. People will pick up a bunch of green onions, and there are a lot of farmers planting green onions in the north. So when will the green onions be harvested? How to harvest them correctly? Let's take a look at them. Green onion planting harvest time 1, according to the sowing time Green onions are generally divided into two seasons, the time of sowing is different, and the harvest time is different. The green onions that were sown in the first year of autumn are generally harvested after May of the second year. The green onions that are sown in the spring are generally harvested after October. If it is used as a winter storage green onion, it is also possible to delay the harvest time of the green onions according to the air temperature. 2, divided by autumn In the countryside, there is also the saying that "the autumn leaves do not receive onions, and the frost will be fixed." It is said when the green onions are harvested. Most of the green onions are harvested in the autumnal equinox. If they cannot be harvested in the autumnal season, they cannot be dragged to the frost. Because the harvest is too late, it is easy to cause the green onions to hollow, affecting the quality and yield of the green onions. 3, according to the throttle temperature Because there are many varieties of green onions, the area where the green onions are grown is very wide. In addition to judging the harvest time of the green onions according to the solar energy temperature, it can also be judged according to the growth of the green onions. Generally, after the outer leaves of the green onions are stopped growing, the leaves can also turn yellow-green, but they have not dried up, and the harvest is carried out within 15-20 days before the soil is frozen. Green onion planting correct harvesting method When the green onion is harvested, the side of the green onion ridge can be first hollowed out with a spade. After the green onion is leaked, the green onion is gently pulled up by hand, and the soil on the root of the green onion is shaken clean, and the green onion cannot be broken, and the outer skin has been The dried yellow leaves are removed. Generally, 4-5 pieces of intact leaves in the middle can be kept. The whole scallions are bundled in a plastic woven bag, usually a bundle of 15 kg-20 kg. The green onions used for winter storage are relatively long, so it is best to bundle them three times and tie them tightly, but not too tight will crush the onion and onion leaves, affecting the quality and storage time of the green onions. The above is some introduction to the knowledge of green onions. I believe that friends in the south should rarely have the habit of collecting large onions, but the north is very common. If the big onion grows, it is necessary to master the harvest time and method. In order to ensure the quality of green onions. 40m Laser Distance Meter is a functional and advanced measuring tools, no need climbing up and down, which is the engineers' best friends.
