Introduction to Bitter Lettuce (Sow Thistle) Varieties and Detailed Seedling Cultivation Methods
In rural areas, many different kinds of vegetables can generally be seen, and bitter lettuce is one of them. It tastes quite good when stir-fried, and it can also be served as a cold dressed dish. Its nutritional value is relatively high. So what varieties of bitter lettuce are there? How is seedling cultivation carried out? Friends who want to know should read on below!
1. What varieties of bitter lettuce are there?
1. There are many kinds of bitter lettuce. Some bear purple flowers, and some bear yellow flowers. Generally, among them, the bitter lettuce that bears purple flowers is more beneficial to the human body. It blooms before the wheat harvest. Generally, once it blooms, it is basically of little use. It is usually picked when it is a seedling or a strong seedling. The purple-flowered bitter lettuce picked at this time has many effects and functions, and it is suitable to be dried by direct sunlight.
2. Purple-flowered bitter lettuce is one of the wild bitter lettuces. Among many types, the purple-flowered bitter lettuce is the most famous. Because it bears purple flowers, it is also called purple-flowered bitter lettuce. Another name for purple-flowered bitter lettuce is Shurong bitter lettuce. The back of the leaves has white fuzz. Generally, it is only useful when picked in the right season. The true place of origin of this bitter lettuce is Guannan in Jiangsu, while Shandong has many mountains. Generally, purple-flowered bitter lettuce must go through wind and frost trials before it can be used by people, while purple-flowered bitter lettuce in the mountains cannot be used, because it is often covered by other plants and cannot fully undergo the frost training of the natural world, so it is instead not beneficial. Do not believe that just because it comes from the mountains it is good. The effects and functions of purple-flowered bitter lettuce are for gallbladder discomfort and the gastrointestinal discomfort caused by it.
2. How is seedling cultivation of bitter lettuce carried out?
1. Land preparation and fertilization
(1) Bitter lettuce was originally domesticated from wild vegetables, so its vitality is relatively tenacious, and its requirements for soil are not high either. If planting it, a place with good ventilation, facing the sun, and convenient drainage and irrigation should be chosen. The seeds of bitter lettuce are also relatively small, so their ability to push through the soil is relatively weak. This requires that our soil must be loose and permeable.
(2) If you want to grow high-quality bitter lettuce, you must choose in advance a plot of land suitable for the growth of bitter lettuce. First, the plot must face the sun, because bitter lettuce is a sun-loving plant and needs a certain length of sunlight every day. If the plot does not face the sun, it will affect its growth and quality. Then, the soil is not required to be very deep, but it must be loose and fertile. The plot should be somewhat close to a water source to facilitate later watering and irrigation work. The acidity and alkalinity of the soil should be moderate and reasonable. After choosing the plot, we need to carry out ground clearing work, then deep plow to a depth of about 20 cm, then break up and level the large clumps of soil, apply an appropriate amount of organic fertilizer, and then mix the soil and fertilizer evenly. The amount of fertilizer used per mu is about 4,000 jin of farmyard manure and about 50 jin of compound fertilizer. Apply the fertilizer evenly to improve the poor fertility of the soil.
2. Sowing
The sowing time of bitter lettuce can be chosen in February or March of spring, or in August or September of autumn. In the north, it can be appropriately delayed or advanced for a period of time. Because of temperature reasons, the specific sowing time should be based on on-site inspection. Generally, the sowing method of bitter lettuce is direct sowing. When direct sowing, it can also be divided into spot sowing, drill sowing, hole sowing, and other methods. Generally, if the planting area is large, direct sowing is used. As mentioned earlier, the ability of the seeds to push through the soil is relatively weak, so when sowing, the seeds should not be sown too deep. The thickness of the covering soil should not exceed 5 cm; generally, 3 to 4 cm is about right. The amount used per mu should be controlled at 1 to 2 jin, spread as evenly as possible, and then water once to maintain soil moisture. For seedling transplanting, the seedling bed should be prepared in advance. The sowing amount per mu should be controlled at about half a jin. When the seedlings grow to a height of 4 to 5 cm, carry out the transplanting work. When transplanting, the row spacing must be well controlled. Generally, the row spacing between planting holes is about 25 cm, and the plant spacing is about 10 cm. When transplanting, try to carry as much of the original soil as possible on the plant, so as to ensure the survival rate of the plants to the greatest extent.
