Planting melons and beans around Qingming?

What does this proverb mean before and after Tomb-Sweeping Day? The rural saying "planting melons and beans before and after Qingming Festival" only refers to a general scope or a specific area. In actual production, this proverb does not apply to all regions. Every region has its own climate characteristics, and when and what to plant is determined by the local climate characteristics. Several generations have inherited and summarized the experience. Bizhi, in our place, it is not "planting melons and beans before and after Qingming Festival", but "Qingming eggplant grows summer melons". During the fifteen days from Tomb-Sweeping Day to Grain Rain Festival, only eggplants, peppers, tomatoes, beets, potatoes and various vegetables can be planted, but melons cannot be planted.

Cann't grow melons doesn't mean that the temperature and ground temperature are too low to sprout, but in the months from Tomb-Sweeping Day to long summer, the probability of frost disaster is very high. Melons germinate quickly and emerge in a short time, and can emerge in about seven days after planting plastic film. In the early stage, the cotyledons were very big and extremely afraid of frost. If there is frost disaster in strong cold air, it may cause no seedlings. Now the seeds of melon seeds are hybrids, and the seeds are very expensive. Due to different varieties, the cost per mu of seeds is between 150 yuan and 200 yuan. In case of frost disaster, it will cause great losses to replanting. Delaying planting properly will not obviously affect the yield and quality of melons, but it can greatly reduce the probability of frost disaster. Eggplant, pepper, tomato, potato and all kinds of vegetables can be planted in Tomb-Sweeping Day, because they grow late and have small buds at seedling stage. Winter melon planting has always been a solar term in long summer.

In recent years, with the change of the climate, all kinds of crops have been planted in advance, but the planting of melons should not come to Tomb-Sweeping Day in advance, and it should be within ten days before the Long Summer Festival after the Grain Rain Festival at the earliest. As the saying goes, it is not accurate to plant melons and beans before and after Tomb-Sweeping Day. Because the temperature before and after Tomb-Sweeping Day is very unstable, it should be said that it is more appropriate to plant melons and beans before and after Grain Rain. In the area south of the Yangtze River, land melons and vegetables can be planted after Qingming. But you should also use plastic film to keep warm, or you will suffer heavy losses in case of cold in spring. In the area north of the Yangtze River, after ten days of Qingming, the air flows. However, sweet potatoes and vegetables are also planted in Grain Rain, and the solar terms and tide wait for no man, and offenders will suffer. Practice has proved that good results can be achieved only if planting does not violate agriculture. Is it out of season or sowing ahead of time? Take cold protection measures. Don't let the old man suffer in front of him.
