For the winter in the north, there are few varieties of vegetables available for planting. Usually, people will be accustomed to growing spinach, coriander, garlic seedlings, but in the case of everyone planting these vegetables, due to the abundant market supply, which will greatly reduce the planting efficiency. If you want to improve the efficiency of planting, you need to change to other vegetable varieties. But what vegetables are better to grow? Many people are undecided. To this end, today we specially recommend a vegetable variety that is both common and uncommon for you to choose to plant.
The vegetable variety to be recommended today is called "Sherry".
Sherry is a mustard cultivar of the family Cruciferaceae, brassica. It is an annual herb. The average plant is about 150 cm tall, and its young stems and leaves have spiny hairs and a spicy taste.
In the countryside, sherry is known as a spicy dish, and its leaves contain 9 vitamins, 7 minerals, and fiber components associated with diet and protein. In addition, it also contains relatively high vitamins, calcium, iron and other nutrients. It has appetizing, detoxifying, reducing swelling, blindness, cough and phlegm, eliminating gum swelling and rot and other effects.
Although the leaves of the sherry are hairy, they are delicious, crisp and delicious, and can be eaten as a salt pickle, stir-fried with pork, and can also be used to stew tofu. In short, there are many ways to eat sherry.
In some people's minds, sherry is planted in the fall and picked in early winter. In fact, in the winter, it is also possible to plant snow and hazel. If you plant snow lily in the winter, you can sow it from late September to mid-October, and as long as it grows out of the ground at temperatures above 15 °C, it will not freeze to death. Moreover, the snow is more brittle and tender and has higher nutritional value.
Snow lily does not have high soil requirements, but it will grow better when the soil is fertile and loose. It is best to choose a sunny, well-drained plot before planting, so that the snow can grow more quickly.
If you plan to plant sherry in winter, you can do so using the following methods:
<h1 class="pgc-h-arrow-right" >. site preparation</h1>
Before sowing, you should first apply foot fertilizer, generally 500 to 1000 kg of fully decomposed organic fertilizer per mu; after fertilization, deep ploughing should be carried out to make the soil more loose. After deep ploughing, the width of the furrow is generally about 150 cm, after the furrow is done, it can be sprayed on the furrow surface with 50% octyl thiophos 1000 times liquid to control underground pests.
<h1 class="pgc-h-arrow-right" >2. Sowing seedlings</h1>
Sowing is generally carried out by means of sowing, which can spread the seeds evenly on the furrow surface, and then cover a thin layer of fine soil, and the thickness of the fine soil should not exceed half a centimeter. If the cover is too thick, it will affect the emergence of seedlings. After emergence, the seedlings should be carried out in time, it is best to control the seedling spacing at about 2 to 3 cm, and apply nitrogen fertilizer and water once after the seedlings to promote the growth of seedlings.
<h1 class = "pgc-h-arrow-right" > three, colonization</h1>
Colonization can be carried out when the seedling age is about 30 days and the seedling grows to 5 to 6 true leaves, and the colonization density is generally 30 to 40 cm in row spacing and 25 to 30 cm in plant spacing. After colonization, it should be watered with sufficient root water, and under normal circumstances, about 5500 plants can be planted per mu of land.
<h1 class= "pgc-h-arrow-right" >4</h1>
After 15 days of colonization, medium tillage and weeding should be carried out to prevent soil compaction, promote soil permeability, promote plant growth, and then, according to the growth situation, 2 to 3 times of medium tillage. At the same time, after colonization, fertilizer water should be applied, the fertilizer is mainly nitrogen fertilizer, and some phosphorus and potassium fertilizers should be appropriately applied to improve the disease resistance of plants and improve yield. The specific amount of fertilizer can be flexibly mastered.
<h1 class="pgc-h-arrow-right" >5. Control of pests and diseases</h1>
In winter, the snow is colonized and there are fewer pests and diseases. If pests and diseases occur, they usually occur in the spring of the following year. The main pests and diseases of sherry are viral diseases and aphids.
If a viral disease occurs, 20% virus A wettable powder 500 times liquid can be used for prevention and control; if an aphids appear, pesticides such as 10% net wettable powder 1500 times liquid can be used for spray control.
The above is the cultivation method of sherry, which should be said to be very simple. According to reports, the average economic benefit of planting snow lily in winter can reach 7,000 yuan per mu, which is better than the economic benefits of planting spinach, coriander and garlic seedlings. Therefore, friends who are interested in planting can try planting it.
