When is the best planting time for autumn cucumber? How to sow autumn cucumber is better?

Autumn cucumbers in our area are usually planted in early August. Because the growth cycle of cucumber in autumn is relatively short, it needs to be harvested before frosting. The latest sowing date of cucumber in autumn should not exceed beginning of autumn. Of course, it can also be planted at the end of August. Cucumber can be sown in autumn, and it can be sown. Sowing planting usually adopts hole sowing method, and each hole is sown with three seeds. Simple seedling establishment after germination laid the foundation for increasing cucumber yield in the later autumn. Generally speaking, the growth of cucumber in autumn is greatly influenced by temperature, and the planting time should be combined with the natural conditions in this area.

In some areas, autumn cucumber was planted in mid-July, that is, five days before the summer solar term, and in some areas, it was chosen 3 ~ 2 days after the summer solar term, but it was also the focus of local temperature changes. It rained heavily in most parts of China in July and August. If autumn cucumbers are planted, it is necessary to prevent the flood of precipitation. Cucumbers like autumn humidity, but they are not soaked well. People often say that "cucumbers that can't be soaked will not die from dry waves", but if the soil is too large, it is not conducive to the growth of cucumbers in autumn. For some areas, autumn cucumbers are mostly old genius pears, and the temperature difference between day and night is too large, which is not conducive to cucumber flowering and cucumber growth. Therefore, the temperature difference between day and night should be kept at 12 ~ 3 degrees as much as possible.

Frosting is one of the solar terms that most vegetables stop growing. Many vegetables' vines or straws stop growing after frosting. What looks crooked is rotten vegetables, old and ugly. The first frost this year is 65438+1October 23rd, and the first frost is 70 days, so we can plant open-air autumn cucumber. In fact, we planted autumn cucumbers and autumn knives here from the end of June, when summer cucumbers began to bear fruit, and the fruiting period took about one month, so planting autumn cucumbers in advance, as long as the summer cucumbers were picked, we could get autumn cucumbers. Plant a bunch in late June, a bunch in mid-July, autumn cucumbers in mid-August at the latest, and vines grow in summer. After beginning of autumn, the temperature is high in the daytime and just suitable for their growth at night, so the fruiting period of cucumber is much longer than that of summer cucumber.

Planting autumn cucumbers is easier to manage than summer cucumbers. At this time, the temperature is not so humid, the sun is strong during the day, the night is breezy, the temperature difference between day and night is large, and there are few pests and diseases. As long as the permeability of cucumber vines is good during management, it is almost unnecessary to spray pesticides to control pests and diseases. Cucumber in autumn is watered less than cucumber in summer. Cucumber in summer is watered almost four times a week, and cucumber in autumn can be omitted if it is planted on crops. Farmers who like to eat fresh cucumbers in autumn can now plant fewer trees, plant them again in ten days and a half, and eat tender cucumbers at home.
