Vegetables suitable for the Millennium.

Vegetables suitable for Millennium cultivation: spinach, Shanghai green, lettuce, potherb mustard and red vegetable table.

1, spinach

Spinach, also known as Persian dish, red root dish and parrot dish, is a kind of vegetable that likes cold environment. Relatively hardy. Its leaves can tolerate the low temperature of -6 ~ 8℃, and seeds can germinate at 4℃. The optimum temperature for growth is 65438 08℃, and the optimum temperature for vegetative growth is 65438 07℃.

Soak the seeds in clear water for half a day three days before sowing, put them in an environment of 20℃ to accelerate germination, and then sow them after germination. Spinach has large leaves, tender tissues and high requirements for water. Keep the fields moist every day. After a real leaf appears, sprinkle manure once, and after two real leaves, interplant and weed in time. Apply more decomposed manure in the early stage, and topdressing urea and phosphorus and potassium fertilizer twice in the growing period for about 30 days.

2. Shanghai is green

Shanghai green, also known as Suzhou green, Qingjiang vegetable and rape, is a vegetable that likes cold weather. The optimum growth temperature is 65438 08℃. It is shaped like Chinese cabbage, with fewer leaves and more stems, and the stems are white, like a gourd ladle. Shanghai green petiole is thick and fiber is fine, which is especially sweet and delicious.

When sowing, cultivate intensively. After the vegetable seedlings grow, choose the tall ones, commonly known as geese don't eat grass. The fixed value is generally 30cm*20cm. Keep the field moist at seedling stage, and start topdressing after 4 days of planting. Apply 20 kilograms of urea each time, preferably with a water pipe, and topdressing 3 times according to the growth period. You can harvest in a month.

3. Lettuce; lettuce

Lettuce, also known as lettuce, is also called goose dish. Its leaves are obovate, crisp and refreshing, slightly sweet when eaten raw, and it likes cold environment. The optimum temperature for growth is 65438 07℃, and the optimum temperature for seed germination is 65438 08℃. If the plant does not germinate above 30℃ and continues to grow above 26℃, the leaf quality will become coarse and old, which will affect the taste.

Seeds can be sown. When the seedlings grow to 2-3 true leaves, divide the seedlings according to the spacing of 6 cm. When the seedlings grow to 4-5 true leaves, they can be planted. Before planting, fully apply decomposed organic fertilizer, deeply turn it after application, pour enough water on the soles of feet, cover the border, keep enough water during the whole growth period, and combine with watering and topdressing nitrogen and phosphorus fertilizers to eat it in about 50 days.

4. Mustard

Snow mustard is also called snow mustard. Because its leaves turn purple in autumn and winter, it is called potherb mustard. It is an extremely cold-tolerant vegetable. Even if it is covered with snow and ice, its stems and leaves can still remain green, so it is also called "spring is not old" and "potherb mustard". Its edible parts are leaves and petioles, which are often pickled and eaten.

Apply sufficient base fertilizer, water the soles of feet before sowing, and cover with straw or wheat straw after sowing to promote the germination and emergence of seeds, and keep the field moist at seedling stage. When the seedlings grow the first true leaf, water them with dilute fertilizer once, weed them in time when two leaves are one, plant them after 5-6 true leaves, apply compound fertilizer topdressing, and harvest them when the seedlings grow to 8- 10 cm.

5. Red dining table

Red vegetable table, also called red vegetable and Zi Yuan, is a kind of extremely cold-resistant vegetable. The colder the weather, the more delicious it tastes, so people like to bolt the stems that grow in the snowy solar terms. At this time, the color is the reddest, the tenderest and the best.

Soil preparation and fertilization before sowing, then sowing, keeping the soil moist after emergence, watering the first true leaf with dilute manure once, sowing in time when two true leaves are concentric, watering the five true leaves in time when sowing, watering frequently every day, applying appropriate amount of human and animal manure at the initial stage of bolting, appropriately increasing nitrogen fertilizer, and topdressing for 3-4 times in a lifetime, at this time, the buds are still in full bloom.
