Spinach, lettuce and artemisinin are common leaves and vegetables that many people like, and are grown in most parts of the country. However, the cultivation of these leafy vegetables tends to be done in spring and autumn, as some of the leafy vegetables prefer cool environments and are difficult to grow at high temperatures. It's almost autumn. After autumn, all kinds of vegetables are ready to grow. So, when is it better to plant vegetables such as spinach, lettuce and artesin? How do we grow it? Let's take a look。
Spinach
The impression is that spinach can only be grown in spring and autumn. Indeed, there is now a large variety of spinach, some of which can be grown four seasons a year, but more so in spring and autumn, generally in february-march, in cold areas in april, and in autumn in august-september. If winter spinach is to be grown, it will be a little late, around october-november. However, specific planting times are based on the local climate, with earlier planting in low-temperature areas, later planting in high-temperature areas, generally 15-30 degrees for spinach growth and 15-25 degrees for common varieties。
Lettuce
As is the case with spinach, most areas are growing in the spring and autumn, and many are growing on a perennial basis. However, there is generally more cultivation in the early spring and autumn, while the spring season of raw vegetables tends to be in february-april, and the autumn season is usually in august. In some warm areas, winter vegetables are grown, usually in october-november。
Artemisium
Artemis is less adaptable than spinach and lettuce, which are neither cold nor heat resistant, and the most suitable planting time is spring and autumn, but early and long and late and low. The field artesian spring is usually cultivated in march-may and in the autumn in september-october, at a temperature of not more than 30 degrees. If planted in a shed or balcony, the spring could be a little earlier and the fall could be a little later。
Methods of cultivation
1. Selection of varieties
There are many varieties of lettuce and spinach, both heat-resistant and cold-resistant, which require the selection of suitable varieties based on planting times and local temperatures to ensure long standing and yield。
Seed treatment
Vegetable seeds, such as spinach and lettuce, should be immersed in water for eight hours before planting, then impregnated in 15-20 degrees, and then seeded, thus increasing the rate of seedling. It can also be immersed in the freezer room for one day and then sprouts. Of course, if the temperature is less than 28 degrees at the time of planting, it can be sowed directly without a seedling。
3. Sowing methods
Cultivation can be done by means of sowing and stripping, in accordance with local planting practices. It is important to water and sow the soil before it is soaked, whether soaked or broadcast. Since the seeds are small, so that they are spread evenly and not so much, the seeds are soaked that the seed is so difficult. After planting the seeds, do not top it too thick, about a centimetre. When the soil is covered, it is best to cover items such as sunnets and weeds to keep them wet and to remove the cover in time for seeding。
After seeding, remember that the soil should be kept wet, seeded in time for seedlings, and raw vegetables for planting. When the leaf grows, fertilizer can be properly followed up on the basis of strength to promote faster and better growth。
