What should I pay attention to when planting water spinach?

Generally speaking, in the south, its planting period is in April and July, of course, if it is planted in a greenhouse, there is no time limit, that is to say, water spinach can be eaten all year round, no matter what time period is no problem. Now we are mainly talking about the absence of greenhouses, so it will be in April, or May, June, and July, which is in the south. The climate in the south is relatively warm, and sometimes it is hot in May and June, which is especially suitable for the cultivation of water spinach.

If it is in the north, then it needs to be postponed for about a month, and it is better to choose planting after July. The climate in the north is relatively dry and cold, so it is more conducive to the growth of this water spinach to be planted after August. <>

When sowing, be sure to turn the soil to make the soil softer, if conditions allow, it is best to put a layer of ash on it. The seeds are easy to be used by some ants, so it is necessary to stir some insect repellent agents to sow seeds to avoid the seeds being eaten by insects and ants. Sowing does not need to be particularly deep, about one or two centimeters deep is enough, and then you need some softer soil, on which you can put some straw to keep it moist and conducive to the growth of water spinach.

Remember to water after sowing, the watering cycle also depends on the humidity of the land, generally speaking, it is normal to water once every 2 or 3 days. Because the land is relatively wet, then it is better to promote the germination and growth of seeds, otherwise it will affect the germination rate and affect the harvest from me. At the same time, remember to clean up some weeds, after all, the germination of seeds may be slightly slower than the growth of some weeds, for weeds should be sprayed with some herbicides in time, so as not to remove weeds when the time will have an impact on the sown plot.

After that, it is necessary to choose insect control, especially after the buds have grown, spray pesticides in time to avoid some insects to eat some leaves, and you can choose some pesticides such as pesticides for prevention.

When planting water spinach, it is necessary to choose some fertile soil, prepare for watering and fertilization in advance, and lay a layer of plastic film after planting water spinach, which can play a role in moisturizing, and can also avoid some weeds affecting the growth of water spinach.

When planting water spinach, you should pay attention to planting it in the greenhouse, and after it survives, you should add nutrients and fertilizers as soon as possible, and pay attention to the supplement of light, so that the water spinach will grow very big.

When planting water spinach, we must pay attention to the moisture of the soil and the fertility of the soil, and choose good vegetable seeds.

Water spinach likes a warm environment, the cold-resistant nature is not very high, the temperature in winter needs to be kept above 10 degrees, and at the same time can withstand a certain amount of high temperature in summer, so there is no need to do too many measures in summer. The normal growth soil needs to be moist enough to replenish water in time, and at the same time, more watering can make the growth rate of the plant faster, so that the yield will naturally increase a lot. Drought tolerance is very low, so try to avoid dryness.

The normal growth of water spinach needs to maintain sufficient light, so that it can photosynthesize, and the branches and leaves will grow more tender and green, if the light is not enough, the branches and leaves will become very short, and the color will not achieve the effect of pre-wide infiltration period. Fertilizing fertile soil is the only way to grow ideal plants, and water spinach is no exception, and it needs to be fertilized with some nitrogen fertilizer during the growing period to allow it to fully absorb nutrients. Of course, the amount of fertilizer should not be too much, and it is necessary to pay attention to thin fertilizer and frequent application.

Propagation and sowing is the main way of reproduction of water spinach, before sowing the seeds to soak in water for a day, after sowing can be sown, after sowing to gently cover with soil, and then keep the soil moist, at the same time the temperature does not need to be too high, keep the environment warm enough, wait for germination after the socks can be transplanted. Pruning water spinach does not need to be pruned, only the yellowed branches and leaves need to be removed, and diseased branches and leaves may appear in the case of poor growth care, so they also need to be pruned, and the others almost do not need to be pruned.

Brown spot disease occurs frequently, this disease is mainly caused by poor ventilation and too dense planting distances, so it is necessary to use wettable powder to control and prevent, and at the same time, it is necessary to cut off the diseased branches and leaves in time. Pest aphids may appear during the growing period and gnaw on the branches and leaves of water spinach, so it is necessary to use some insecticides to completely eliminate them. It is not toxic and is a vegetable with very high nutritional value, so it can be grown in a large area.

Attention to details].

1. Water spinach likes high temperature and humidity environment. Seed germination requires more than 15; The axillary bud germination of the seed vine must be kept above 30 in the early stage, so that the budding can be quickly and neatly; The suitable temperature for vine leaf growth is 25 30 °C, and the higher the temperature, the stronger the vine leaf growth, and the shorter the picking interval. Water spinach can withstand 35 to 40 high temperatures; Below 15 vines grow slowly; 10 The growth of the vines below stops, and they are not tolerant to frost, and the stems and leaves die when they are exposed to frost.

The temperature of the vine should be kept at 10 15, and there should be a high humidity, otherwise the vine is easy to freeze to death or wither.

2. Water spinach likes high air humidity and moist soil, the environment is too dry, the vine fiber increases, and the coarse age is inedible, which greatly reduces the yield and quality.

3. Water spinach likes sufficient light, but it is also more adaptable to dense planting. Water spinach does not have strict requirements for soil conditions, but because it likes fertilizer and water, it is still better to have a more viscous and heavy soil with strong water and fertility retention. The leaf tips of water spinach grow in large quantities and rapidly, requiring a large amount of fertilizer, strong fertility tolerance, and a particularly large need for nitrogen fertilizer.

4. Disease prevention and control.

Wheel spot disease and brown spot disease are two common diseases of water spinach.

Prevention and control methods: 1) Reasonable fertilizer and water. According to the characteristics of the variety, fertilize reasonably, increase the application of rotting organic fertilizer, pay attention to the combination of nitrogen, phosphorus and potassium to prevent the defertilization of vegetable plants; Water reasonably, do not over-irrigate, drain water in time after rain to reduce humidity.

2) Remove old leaves. Crop rotation for more than 2 years should be implemented in seriously diseased fields, and diseased old leaves at the bottom of vegetable plants should be removed in time.

3) Pharmaceutical prevention and control. At the initial stage of the disease, you can choose to spray 1200-1500 times of 25% rust wettable powder, 1000-1300 times of 50% promethane wettable powder, 600 times of 70% mancozeb wettable powder, 500-600 times of 65% zepzeb wettable powder, 600 times of 70% thiophanate-methyl wettable powder or 500 times of 75% chlorothalonil wettable powder. Spray once every 7-10 days, and take the drug 3-4 times.

Sock beams. 4) Clear the garden in time. After harvesting, remove the diseased residues in time, turn the soil deeply, and eradicate the weeds in the field.

Be sure to choose the right variety for sowing, to maintain the suitability of the land, to fertilize in advance, and then plant these seeds in it, be sure to pay attention to the control of pests, to spray pesticides, to fertilize and water reasonably.

To choose fertile soil, choose good seeds to plant at the right time, and be sure to pay attention to soil moisture when planting.

Planting methods and precautions for water spinach: land preparation, application of foot fertilizer, seed germination, sowing, heat preservation and cold protection, precautions.

1. Prepare the land for furrowing

Direct seeding water spinach is a fast-growing vegetable, which has high requirements for soil quality, and sandy loam soil with rich organic matter content should be used for planting. Generally, the furrow is 15-20 meters long, the furrow bread ditch is wide and the furrow is 30 cm deep.

2. Apply plantar fertilizer

After each stubble is sown, the mixture of river sand and well-decomposed and sieved soil miscellaneous fertilizer is evenly spread on the furrow surface as covering soil, and 2000-2500 kg of soil miscellaneous fertilizer is required per mu.

3. Seeds urge the buds

8-10 days before sowing in the natural balance of the shade and humid environment to soften the seed coat, about a week later, the seeds will be soaked in 20-30 water for 20 hours, picked up and washed to keep moist, and the seeds can be sown after the seeds are white. Prevent seed rot through germination and improve the uniformity of emergence.

4. Sowing

It can be sown or sown in strip, which is more conducive to harvesting. The amount of seeds per mu is 25-30 kg, and the cultivation season is appropriately thinned, and the cold season is densely sown, and the soil is covered with sufficient water.

5. Heat preservation and cold protection

The use of plastic film small arch shed for cold and dry season insulation, moisturizing, rainproof, generally the lowest temperature below 15 should be used and contain small arch shed insulation, daytime sunny day temperature can increase the temperature 5-10.

6. Precautions

Common pests and diseases of water spinach include anthracnose, cabbage worms, etc. We should focus on prevention and enhance the disease resistance of water spinach. Regularly disinfect the vegetable garden, do a good job of cultivating and weeding, control the amount of water and fertilizer, and avoid excessive water and fertilizer that will affect the growth of water spinach.

Generally, water spinach is usually grown between the end of April and the beginning of May. Because it grows fast and has a strong branching ability, it also has a higher demand for fertilizer water, so it is necessary to apply enough basal fertilizer when fertilizing. When sowing, choose new annual seeds that are fuller and brighter in color, and the germination rate can reach more than 98%.

Because the growth of water spinach takes a certain amount of time, and there are certain requirements for light, the seedling time of water spinach is basically 4-7 months or 6-8 months, and the temperature at this time, this environment is suitable for the growth of water spinach.

Water spinach needs to be fertilized many times in the process of planting, because water spinach does not have very high requirements for soil, but sufficient fertilizer is still very necessary, and sufficient base fertilizer is put in before planting, mainly organic fertilizer, microbial agent, with an appropriate amount of water-soluble fertilizer. In the late growth stage of Chinese cabbage, it is necessary to top dressing in time, mainly using water-soluble fertilizers with balanced quality elements, supplementing nitrogen, phosphorus and potassium elements, and providing sufficient nutrients for the growth of Chinese cabbage.

Before sowing spinach, we should first prepare the ground, turn the soil and make the bed. Before land preparation, the weeds in the field should be cleared in advance to avoid the decline of germination rate caused by the competition between weeds and seeds for nutrients after sowing. In order to prevent spinach pests and diseases in advance, it is necessary to prepare in advance in daily management.

When the spinach enters the middle and late stages of growth, the spinach surface can be sprayed with green bags of fertilizer.

It can not only increase the yield of crops, but also improve the resilience of crops. Cabbage is a great wild vegetable, it's highly nutritious, and it contains eight times more vitamin B1 than tomatoes. And ** is very cheap, you can generally separate the stems and leaves of spinach to fry, pick a handful can be made into two kinds of vegetables, the taste of the leaves is also very good, many people like it very much.

Water spinach has a good medicinal effect, eating more can also maintain good health, it has the effect of promoting intestinal peristalsis, defecation and detoxification; After consumption, it can reduce intestinal acidity, prevent the imbalance of intestinal bacterial community, and help prevent cancer; It also cleans teeth, prevents tooth decay and removes bad breath. In addition, it can also prevent infection, clear away heat and relieve fever, cool blood and detoxify, and prevent dysentery.

When planting, it is important to pay attention to the temperature, the quality of the seeds, the fertility of the soil, the planting technique, fertilizers and pesticides. Growing water spinach can provide people with vegetables, which can meet the needs and quantity of the market. When planting, we must water and fertilize in time, choose high-quality varieties, and spray some pesticides regularly to avoid insect pests.

It is necessary to pay attention to the need to have sufficient sunlight when planting, and should also pay attention to protecting the roots, not to water too much, to turn over the soil, and pay attention to the humidity control at 40%, because after planting hollow seedlings, people can also eat, and when planting, they can be planted in relatively fertile soil and fertilize more.

Be sure to pay attention to the variety, be sure to pay attention to the condition of the soil, pay attention to watering, pay attention to fertilization, pay attention to the drainage of the land, because this dish is very tasty, so people will choose to eat it.

Water spinach grows at around 25-30 temperatures, and the best time to grow is spring and autumn. Choose rich, breathable sandy loam soil for planting, arrange the soil before planting, and apply a certain amount of organic fertilizer. Select suitable seeds, soak them in warm boiled water before sowing, encapsulate them in moist gauze, and then put them in an environment of 30 to germinate.

The seeds are sown, fertilizer is applied after sowing, water is sprayed to maintain moisture, and they are kept under abundant sunlight.

PlantingTime

Water spinach is a very good vegetable to grow, which is not harsh on the growing environment and can be grown all over the country. For water spinach, the growth temperature is about 25-30, and the best planting time is spring and autumn, which are suitable for the climate, and can grow as early as possible after planting, and the survival rate is also very high.

Prepare the soil

Its roots cannot hold water at its roots, so it should not be planted in low-lying areas where water is stored, and can be planted in rich, breathable sandy loam soil. If you have a small amount of potted plants, you can prepare the soil yourself. After the soil is clear, it is also necessary to apply a certain amount of organic fertilizer as a base fertilizer.

Soak seeds to promote germination

Choosing the right seeds in advance can not only ensure good growth, but also improve efficiency. The seeds of water spinach are thicker and harder, so they should be soaked for germination before sowing and soaked in warm boiled water for a period of time, so that the seeds can completely absorb water. Encapsulates into moist gauze and subsequently puts them in 30 conditions, for which to promote germination.

Carry out sowing

Dig a pit in the soil, then sow the seeds, cover them with fine soil, spray them with water to maintain the ambient humidity, and wait for the seeds to germinate.

Conservation management

Immediately after sowing, apply fertilizer, spray water to maintain moisture, raise in abundant sunlight, and when the seedlings grow to about 17 cm, they can be picked to solve the problem. After 30 days after sowing, the water spinach can be picked when it has grown to about 35 cm.

Biological characteristics and planting characteristics

Water spinach, fibrous rhizome shallow, strong reconstitution function, stem nodes short, oblate or nearly rounded, hollow, dense to pale green. Cotyledons opposite, elliptic, symbiotic leaves, oblong-ovate, apical cardiovascular-shaped or lanceolate, entire, leaves smooth, dense or pale green. The leaves are 13-17 cm long and 8-10 cm wide, and the leaf stems are 12-15 cm long, hollow and concave.

The seeds are nearly ring-shaped, thin-skinned, dark brown, and weigh 32-37 grams per 1000 seeds. Water spinach is bred from seeds or young stems.

Water spinach likes warm and high temperature and humidity environments

Seed germination needs more than 15, and the temperature of vine growth is 25-30, when the temperature is higher, the vine growth is more abundant, and the harvest time interval is shorter. Water spinach can tolerate 35-40 high temperatures, 15 vines below stunted growth, 10 below vines stop growing, do not resist frost, and the stems wither when frosted. Water spinach prefers higher air humidity and moist soil, and the chemical fiber of the over-dried rattan increases and the quality of taking it decreases.

Water spinach also likes abundant sunshine, but it also has a strong adaptability to sparse plants. Water spinach is better in soil with heavier viscosity, strong water retention and fertilizer retention efficiency, large fertilizer application amount, and strong fertilizer tolerance, especially in the large demand for basal fertilizer.
