Lettuce is all too familiar to everyone, it is a more common vegetable in our rural vegetable gardens. Those who observe carefully will find that the lettuce grown by some old farmers is thick and strong, while the lettuce planted by some old farmers is thin and tall. So, which one is a good lettuce? The answer is obvious, of course, the thick and sturdy lettuce is more popular with consumers. The reason why lettuce appears thin and long is mainly related to the climate discomfort and improper watering.
People who have planted lettuce know that lettuce planted in spring and winter tends to grow stronger, while lettuce planted in summer and autumn is easy to appear thin and long. The main reason for this is that the temperature in the spring and winter is low, the growth and development of lettuce is slow, it will first absorb nutrients to grow roots, and then grow stems and leaves; and the summer and autumn temperatures are high, lettuce grows and develops rapidly, and nutrients are absorbed by the stems and leaves of lettuce, which is easy to form lettuce, which will naturally grow thin and long.
In addition, improper watering can also lead to the phenomenon of lettuce appear thin and long. Many people think that lettuce grows thin and tall, which is a manifestation of the soil being too wet and watering too much, so they do not water the lettuce. As everyone knows, the more you don't water the lettuce, the more the lettuce will grow thin and tall. In fact, lettuce grows thin and tall, is the soil drought, lack of water performance, only timely watering of lettuce, in order to promote the growth of lettuce root system, in order to make lettuce grow thick and strong.
For how to prevent lettuce from growing thin and tall, the most important thing is to do 2 points: First, choose the right season to plant, it is best to be able to colonize lettuce when the temperature is low. Like our Chuxiong area in Yunnan, lettuce is generally planted in early winter or late spring; for lettuce planted in greenhouses, the temperature in the shed should be strictly controlled to avoid the phenomenon of excessive temperature in the shed. The second is to water frequently, especially when the lettuce is slowly seedling, it is even more important to pay attention to not lack of water, otherwise, the lettuce will only grow stems, not roots. However, while watering the lettuce, we must also pay attention to 2 points, one is not to water with large water, otherwise, the lettuce is easy to crack; the second is to do a good job of drainage to prevent the lettuce from flooding and causing root damage.
Of course, there are many reasons why lettuce grows thin and tall, and there are many ways to prevent and treat it, but in Lao Zhao's view, the main reason is still due to climate discomfort and improper watering, what do you think?
