How to select vegetable seeds? What are the breeding methods?

Cabbage is one of the cruciferous vegetables, named because its tuber flat garden is as large as a garden plate. Dish is a kind of characteristic dish among the alpine out-of-season vegetable varieties in recent years. Its appearance is similar to that of radish, the meat is delicate, white, crisp and tender, sweet and slightly spicy, and its taste is good and unique. At present, although the planting range of dish is narrow, it is introduced in many places. So how to choose the seeds of vegetables? What are the methods of raising seedlings? Let's get to know it.

How to choose the seeds of vegetables?

Before planting dish vegetables, the first thing is to select its seeds. It is suggested that some varieties with high yield and strong disease resistance should be selected as far as possible. In addition, another point is very important, because cabbage seeds need conditions such as a large temperature difference between day and night in the process of growth and development, so we must pay attention to this problem when selecting seeds.

What are the methods of raising seedlings?

1. Land selection and preparation

In order for growers to obtain better yield and quality, sandy loam with deep soil layer, convenient drainage and irrigation, loose and fertile soil should be selected. If it is to be cultivated as an out-of-season vegetable in high mountain, it is necessary to plant land at an altitude between 1200m~1800m. When selecting the land, remove the large aggregate soil, tablet mud or stone, and after finishing, sprinkle 1000-1500 kg of rotten farm manure, 50 kg of calcium superphosphate and 5 kg of magnesium sulfate with the soil or shallow mixing.

2. Fine breeding

The seedling raising time is also slightly different in different planting areas, so we should pay attention to the distinction. When raising seedlings, it is best to use a nutrition bowl or nutrition cup to keep the seedlings warm. After the seeds were treated with low temperature, one seed per nutrition bowl (cup) was sown in nutrient soil to keep the soil moist and loose, and the seedlings could emerge after 3-5 days.

3. Transplanting seedlings

In order to cultivate strong seedlings, the seedlings can be released in sunny days after the seedlings, so as to enhance the cold resistance and stress resistance of the seedlings. When the seedlings of cabbage have 4 or 6 true leaves and the fleshy roots are as large as soybean grains, they can be planted and transplanted according to the row spacing of 0.2 and 0.3 meters. The depth of planting should be enough to bury the base of the first true leaf and pour enough water into the root after planting.

4. Fertilizer and water management

After three days of planting, the seedlings were watered once in the morning and evening to make the seedlings survive, gently remove the straw, expose the leaves, and throw grass around the fleshy root ball to cover it. At the same time, weeding and soil cultivation must be ploughed after rain and before fertilization, watered to keep the seedlings moist, and applied thinly every 3 days. During the whole growth period, mature farm manure was mainly used, and ring fertilizer was applied less to facilitate plant growth and fleshy root expansion.

Generally speaking, dish is a rare vegetable variety in root vegetables, which can be eaten raw, cooked, made in soup, etc., and can also be processed into various pickled products with good crisp taste. And it is also relatively easy to grow, so just pay attention to the seedling raising skills.
