Everyone knows that purple cabbage is a very delicious vegetable. He is a semi-tolerant vegetable and prefers a cool climate. General temperature of 20-25 °C is suitable for outer leaf growth. Into the ball period, the suitable temperature is 15-25 °C. Purple Cabbage has strong cold resistance and can withstand short-term low temperatures of -5°C to -7°C. The soil is most suitable for the cultivation of slightly acidic and neutral loam with good water retention. Let's take a look at the secrets of cultivation of purple cabbage.
First, choose
Variety selection The early maturing variety “Zehongâ€, which was introduced from the Netherlands and suitable for spring exposure, has a purple-red leaf color, an oval ball shape, a single ball mass of 0.75-1 kilograms and a yield of 1500-3000 kilograms per mu. About 65-70 days from planting to harvesting.
Second, sowing time
Appropriate sowing and planting on spring exposed land can be nursed from the middle of January to mid-February, and thousands of seeds can be sowed. Before the planting, the nutrient soil was fully watered, and the soil after the sowing was 1.5 cm thick. Then cover the film to make the seedlings grow early.
Third, seedling management
The average seedling age is 70-90 days, sowing to 2 true leaves occurs 20-30 days. The daytime temperature is 25°C and the nighttime temperature is 15°C. After the seedlings are released, the temperature is lowered to 20°C during the day and 10°C during the night to prevent the hypocotyl elongation of the seedlings. It takes 45-60 days for seedlings to grow from 3 true leaves to 6-8 true leaves. Before the colonization, exercise was performed at a low temperature, maintained at about 15°C during the day and 7-8°C at night, gradually approaching the temperature of the open air. The criteria for strong seedlings are: 6-8 true leaves, short internodes, thick leaves, deep color, thick stems and well-developed root groups.
Therefore, if you do the above three points, your cultivation of purple cabbage will grow even better and you will have more chances of harvesting when you are ripe.
Beans are mainly soybeans, broad beans, red beans, mung beans, soybeans, black beans, cowpeas, peas, sword beans, lentils, kidney beans, chickpeas, dal and so on.
The main nutrients in beans include carbohydrates, protein and fat. Protein in beans is an important component of beans.
â‘ Protein: Soy protein in eight kinds of essential amino acids the human body needs with the United Nations food and agriculture organization (FAO) recommended are very reasonable compared to the ideal value of soy protein has good amino acid composition pattern, rich in glutamic acid, alanine and aspartate and contains high lysine, methionine and tryptophan (amino acid) sulfur content is low, However, some grains contain high content of sulfur amino acids and low content of lysine, so some grains can be appropriately combined with legumes, which can play a complementary role in protein, so as to improve the nutritional value of food .
â‘¡ Fat: soybean and black bean have higher fat content, while other beans, such as kidney bean, except soybean and black bean, have lower fat content, but their fatty acid composition pattern is better, mainly polyunsaturated fatty acid, mainly including linoleic acid, linolenic acid, etc.
â‘¢ Vitamins: beans contain vitamin A, vitamin B, vitamin C and vitamin E.
â‘£ Minerals: different beans contain different minerals, such as soybeans are rich in iron, kidney beans contain calcium, iron, potassium, magnesium.
⑤ Dietary fiber: beans contain dietary fiber, which is good for the body.
â‘¥ Pigment: soybean isoflavones are one of the flavonoids, mainly exist in leguminous plants, flavonoids is a kind of plant pigment. Soybean isoflavones are secondary metabolites formed during soybean growth. It can compensate for the lack of estrogen in women after age 30, improve skin moisture and elasticity, relieve menopausal symptoms and improve osteoporosis. The estrogen effect of soybean isoflavones affects hormone secretion, metabolic biological activity, protein synthesis and growth factor activity.
