Can water spinach live without a heart?

Water spinach can eat leaves.

The crude cellulose content of water spinach is rich, and this edible fiber is composed of cellulose, hemicellulose, lignin, gum pulp and pectin, which has the effect of promoting intestinal peristalsis, laxative and detoxification. Water spinach is cool, vegetable juice has an inhibitory effect on Staphylococcus aureus, streptococcus, etc., the protein content in the tender shoots is 4 times higher than that of the same amount of tomatoes, the calcium content is more than 12 times higher than that of tomatoes, and contains more carotene.

Cultivation techniques. Bracken is a type of amphibious plant that can live in both dry land and paddy fields, but it still grows vigorously when there is more water, and is most suitable for planting in fields with frequent manure water near fertile paddy fields or livestock houses. It can also be planted on dry land with more fertilizer, and planting in dry land can promote more seed production, so it can be cultivated in dry land when leaving seeds.

Bracken has strong adaptability to the soil, both fertilizer and stain resistance, and also has a certain barren resistance, but under artificial cultivation conditions, in order to achieve high yield, clay soil or loam soil rich in organic matter is the most suitable. Bracken is not drought tolerant.

Bracken seeds begin to germinate at about 15, the suitable temperature for growth is 20 35, and the germination is fast when the temperature reaches more than 30 in the early stage of axillary bud germination. The light should be sufficient, but the adaptability to dense planting is stronger, it belongs to the short-day type, especially the vine fern has stricter requirements for short-day than the seed fertle, and it is difficult to flower and bear fruit if the sunshine is slightly longer, so it is commonly used for asexual reproduction.

There are two types of cultivation methods: dry cultivation and water planting. In the north, dry cultivation is the main crop; Dry cultivation and water planting coexist in the south. The early cultivation is mainly dry cultivation, and the middle and late cultivation is mostly water planting.

There are two kinds of water spinach, one is perennial vine and mainly uses the stem for vegetative propagation. Its roots, which are actually stems, are just stems that are pressed into the soil, which are the "seed source" for the next year's production and reproduction. This stem, which has been buried in the soil for several months, stores enough nutrients to be eaten in a dish.

As long as the temperature is suitable in winter, it is no problem to make seedlings for the next year. In fact, the roots on it die in the winter. When propagating, new roots can grow at the stem knots.

I'm from central Hunan, and I used to let the underground stems of this water spinach survive the winter safely. The cellar in the north should be fine.

Another type of water spinach is annual, so there is no such underground stem, and its roots naturally cannot survive the winter.

The long-budding water spinach is also edible, and by September, the old water spinach that grows in the ground is almost blooming, but this water spinach has begun to get old, and the taste and nutrition will be slightly inferior, so it is recommended to pick only the young leaves when eating.

When will water spinach be on the market.

Water spinach is very heat-resistant, not cold-tolerant, generally matures in the spring of each year around April, and is marketed in large quantities in May and July, and can be bought in the market all year round if it is planted in a greenhouse.

Due to the difference in climate, the temperature in the northern region is lower, while water spinach grows faster in a warm and humid environment, so it is less in the north, and the southern region can grow in April and October.

How to pick water spinach.

1. The greener the leaves, the fresher they are.

It is better to choose water spinach with a whole plant, no roots, no yellow leaves or broken water damage, and the greener the leaves, the fresher.

2. The incision has no rot or discoloration.

The incision at the bottom of the stem tube should be free of rot or discoloration, and if it is too dry or lacks moisture, it will not be fresh.

3. The stem tube is thin and the taste is delicate.

In terms of taste, water spinach with thin stems and tubes has a delicate taste; Water spinach with thick stems has a crispy texture. The taste of the greenish stalk is delicate; The cabbage stalk has a crispy texture.

Yes, water spinach can be eaten in any season, but the taste is not as delicious as in summer, and if it is a greenhouse, it is not necessary to have a taste. It is recommended to eat more of these vegetables containing chlorophyll and carotene in autumn. In the face of the frequent influenza period in autumn, it has a good effect on improving human immunity.

Water spinach can still be eaten when it blooms, it's fine.

It can still be eaten, but the taste is slightly worse.

<> take water spinach grown in the open air as an example, which generally dies in winter (dead roots). The good limbs of hollow cabbage are not cold-tolerant, suitable for growing in a warm and humid climate, fertile soil socks, and its seeds begin to germinate in an environment of about 15, and the suitable temperature for growth is 20-35.

Water spinach can live to November every year, the plant is not resistant to cold, the temperature is lower than 10 and then stop growing, water spinach is native to the south, likes warm, humid climate, heat-resistant, not frost-resistant, in the Yangtze River basin provinces can grow in April to October, and water spinach seeds begin to germinate around 15, and the growth temperature is 20-35.

Water spinach is generally planted in April to October every year, its survival time is longer, until November before dying, the plant likes warm, humid climate, heat-resistant, frost-resistant, the temperature is lower than 10, began to stop growing.

Water spinach is divided into two cultivation methods: dry cultivation and water planting, the temperature in the north is low, mainly dry planting, dry cultivation and water planting coexist in the south, and early maturing water spinach generally adopts dry planting, and most of the water plants are cultivated in the middle and late maturity.

Water spinach seed coat is thick and hard, slow water absorption, low temperature in early spring, slow emergence of seedlings, if in case of low temperature and rainy weather, easy to rot seeds, so it should be soaked for 24 hours before sowing, accelerate the germination speed, and rejuvenate the activity of seeds.

After the water spinach is planted with live trees, in addition to cultivating and weeding, in order to improve the ground temperature, it is also necessary to top dressing, after planting for 1 month, in the summer, the temperature rises, the plant grows rapidly, and the fertilizer needs a large amount of fertilizer and water, so as to keep the soil moist, and the fertilizer is mainly applied to thin human manure and fast-acting nitrogen fertilizer.
