Lettuce grown in my family is fat and strong. In our village, my father is an expert in growing bamboo shoots, and all the people who grow vegetables in the village praise him. Some people asked my dad for advice, and then I shared some experiences of growing lettuce in my family.
First of all, we should know that there are several varieties of lettuce, which can be divided into white and green according to the color of lettuce skin, and can also be divided into summer sowing and autumn planting according to the season. As a result, some grow tall and thin, and the leaves are slender and few, which are purple. Some grow fat and strong, so lettuce grows tall and long, not all because of management.
First, the problem of variety.
Lettuce can also be divided into two types according to the shape of leaves: pointed leaf type and round leaf type. Dust-leaf lettuce is a late-maturing variety, which covers a long area and is heat-resistant. It is suitable for autumn and winter cultivation, and some people plant it in spring. The cotyledons of this lettuce are slightly conical, and one of them is purple. Its stem is thin and long, as I just described.
Second, the season.
Whether it is pointed leaf lettuce or round leaf lettuce, it is necessary to choose the season suitable for its growth in order to harvest good products. Generally speaking, lettuce is a cool vegetable. When the weather is hot, the seeds will hibernate, which will affect the emergence of seedlings. It is easy to plant lettuce, which is white and long.
The best planting time of lettuce is autumn and winter. Autumn begins in September, that is, after the Millennium, and can last until February and March without any exaggeration. The quality of lettuce planted in this period is the best, and there will be no tall and thin phenomenon.
Third, management issues.
Lettuce is very prone to overgrowth and bolting, usually in spring and summer. Usually the quality of lettuce grown in these two seasons is not good. In our local area, lettuce is rarely planted in summer after it is harvested in spring.
Because the temperature rises gradually, it is difficult to manage. Lettuce has a characteristic of high drought, high waterlogging and high hunger. In spring and summer, if management is not in place, it is easy to grow tall and thin lettuce.
Therefore, from seedling to harvest, we should carefully observe and understand the growth characteristics during this period, and then water and fertilize according to the situation. Only the lettuce planted in summer grows thin and long, and there are no kinds in autumn and winter.
Also, lettuce planted in spring, the later the temperature, the higher the temperature. Because of vernalization, it is easiest to bolting and blossom when there is a little water shortage. Even if there is no water shortage, it will grow tall and thin.
In a word, to plant lettuce, in general, we should avoid the hot temperature, choose the right planting season and manage it properly. In order to grow lettuce with good quality. Another is that even if lettuce is planted in autumn, it should be planted below 22 degrees according to the local temperature, otherwise it will also cause the phenomenon of "high jump".
