How to solve the phenomenon of sprouting in spinach cultivated over winter?

Then you need to control the temperature around it and renovate the soil.

It is likely that the temperature is too low or the fertilizer and water are not enough to cause early sprouting. Nitrogen and potassium fertilizers should be supplemented in time to promote the growth of plant rhizomes, appropriate watering, keep the soil moist, and keep the plants warm.

Moisture can be used to solve problems like this. Such a similar problem is caused by the transition of moisture to ice that causes spinach to have this phenomenon. The solution is to choose some loose soil so that the water is not easy to condense into ice.

Spinach varieties have strong cold resistance, weak heat resistance and strong winter varieties, as well as strong heat resistance, weak cold tolerance and weak winter hot varieties, strong winter varieties are not too sensitive to low temperature, but they are more sensitive to long sunshine will sprout quickly, so overwintering spinach planting, suitable for choosing strong winter and strong cold tolerance pointed leaf varieties, such varieties are not too sensitive to low temperatures, and are harvested in time in spring, which can avoid the early sprouting phenomenon caused by low temperatures.

Water pouring is a measure to water overwintering crops in the field in winter when the soil begins to freeze. This is an effective measure summarized by Chinese farmers in long-term production practice to protect the safe wintering of overwintering crops. Pour water into spinach in a timely and appropriate amount.

The timing of pouring frozen water should be flexible according to the climatic conditions of the region and year. The soil ground freezes at night and melts at noon the next day at the right time. Pour early.

As soil moisture evaporates, the water accumulated in the soil is lost and sometimes needs to be replenished. If the swelling is late, the ground has frozen, the water cannot penetrate the soil, the rhizosphere is still short of water, the water freezes on the soil surface, inhibits the respiration of the roots, and the dead seedlings are more serious. The amount of chilled water poured should be sufficient to sustain the demand of spinach when it turns green the following year, and it can completely penetrate the soil in a short period of time to avoid flooding.

It is also necessary to determine the frozen water according to the soil quality and the level of groundwater in the soil.

After the sandy soil is sprinkled with frozen water, the topsoil should be watered again when it is dry, and the fine soil should be covered for moisturization. The surface of the cohesive soil is easy to crack after spraying frozen water, and the ground is covered with tiny soil when it freezes to prevent cracking, and the cold water of the soil with high groundwater level is appropriately reduced, and the groundwater level is low. When spinach is sprinkled with frozen water, the ground is prone to cracking.

In particular, sticky soils are more prone to cracking after watering, and thin circle fertilizer can cover the cracks after watering. Cracks are reduced, soil moisture evaporates less, and plays a role in retaining moisture. Spreading fertilizer on the roots of spinach plants will weaken the flow of cold air in the rhizosphere, which has a certain effect on heat preservation.

Harvesting moon cave fertilizer can increase soil nutrient content, and play a role in promoting the inability turnover of winter fertilizer in spring. In particular, vegetable gardens with few foundations, weak soil fertility, and weak seedlings are more important. First, soak the seeds in 35 warm water for 12 hours, remove them to dry or spray, and then cover them with soil and tread water.

Improve germination rate through moisture, waterproofing, water evaporation, sun protection, drought resistance, thermal insulation and antifreeze, soil compaction, suffocation and isolation of pest and disease sources. After the spinach sprouts and emerges in winter, a shallow hoe should be carried out to loosen the soil to play the role of weeding and moisturizing. When the plant grows 3-4 leaves, keep the soil moist and apply top dressing appropriately.

After the plant has grown 5 or 6 leaves, when trying to stop growing, it is necessary to pour frozen water in time, and the time of pouring water should be mastered by the soil surface during the day and cold at night. When pouring chilled water, it is best to use fecal water. Spinach turns green in early spring, which helps speed up growth.

Irrigation is a measure of watering overwintering crops in the field during the winter when the soil begins to freeze. This is an effective measure summed up by Chinese farmers in long-term production practice, which can protect the safe wintering of overwintering crops. Pour the water into the spinach in a timely and appropriate amount.

Freeze water should be poured at the right time. If the water is watered too early, it often causes a large amount of water to evaporate, the moisture is not good, and it is easy to have dead spinach seedlings; If it is watered too late, the water is not easy to infiltrate, forming an impermeable ice layer on the surface, and the seedlings are prone to suffocation and rot and death. It generally freezes at night, and watering is just right during the day.

Combined with watering frozen water, nitrogen fertilizer and high-quality farmhouse fertilizer can be appropriately applied, which can not only play the role of heat preservation and cold protection, but also prevent the soil from cracking and dying seedlings in the following spring, and also reduce the fertilizer water after the spring regreening**. If there is heavy snowfall in winter, the snow should be cleared in time to prevent spinach from suffocating due to the snow covering time for too long.

It is to sow seeds in a timely manner, overwintering spinach is generally sown in mid to late September, before wintering to ensure that there is a growth period of about 50 days, when the cold and freezing weather arrives, it can grow 4 6 leaves as well, sowing too early is easy to grow, sowing too late seedlings are tender and weak, and the ability to resist cold and freezing is weak, which is not conducive to spinach safe wintering.

"For the spinach that is overwintering now, it is over the age, of course it can grow next year, as long as the temperature and humidity are suitable, of course, it can, and it can be integrated with everyone."

There are two special points for wintering spinach planting, one is limited by winter sun conditions, and the spinach planting area should be sunny to the land, so as to obtain more abundant light resources. Second, in fertilization, in order to prevent the lack of fertilizer in the land due to the long winter, a large amount of organic fertilizer and phosphorus and potassium fertilizer should be applied as base fertilizer all applied to the land, which should be sufficient and uniform. These two points can effectively alleviate the defects and deficiencies of objective conditions caused by spinach planting in the winter environment.

In addition to the above two points, the selection of spinach seeds should focus on the characteristics of spinach seeds, such as cold resistance, high yield, and low moss extraction rate. In terms of seeding methods, it is better to sow seeds in the way of live broadcasting. When encountering a furrow in the land, it is necessary to dig a trench and then spread or seed it.

Generally, the sowing time is September or October. About 4 days after sowing, the spinach seedlings begin to emerge, and this is when we need to start the pre-wintering management work. When the spinach grows about 4 leaves, we should focus on water control to promote the development of its root system, so as to store more water nutrients.

After the above operations are completed, it is necessary to add mulch to keep the spinach warm and promote its safe wintering. If the sowing time is relatively late, or the soil fertility does not reach a good standard, you can consider applying water-soluble fertilizer to promote the growth of spinach seedlings, so that they can overwinter at the right young age, and they are vulnerable to cold waves if they grow too large or too small.

After the winter, we did not rush to water, and first cleared the snow and weeds from the land. Wait until the soil layer thaws before starting to water, but at this time you must control the amount of water to avoid too cold to reduce the low temperature, causing frost damage. As the spinach grows, you can start watering twice every six months.

After the spinach gradually grows, it is necessary to pay attention to the timely harvesting, basically around the 55th day, when the harvest can ensure a better yield and quality. All in all, spinach overwintering should consider many variables to help spinach grow.

Spinach contains iron, magnesium, potassium, phosphorus, zinc and rich in calcium and vitamin C, has a good health care effect, because of its strong adaptability to temperature, short growth period, can be stubble to grab seeds, can also be sown in rows, anniversary, alleviate market demand, plants can be eaten regardless of size, and the leaf color is dark green, the leaves are thick, there is no sprout for the best quality, but in the planting and production process, often due to many factors such as inadequate management, it will cause spinach to appear early sprouting during the growth period, resulting in reduced yield and poor quality, Reduced economic benefits.

In particular, the cultivation of overwintering spinach has a long growth period, from sowing to harvesting, it is necessary to experience the mild temperature in late autumn, the cold climate in winter, and the fluctuation of temperature in early spring.

Green cabbage and spinach are sown from late September to early October, and the seedlings are harvested in the spring of the following year. The seedling land is made into a furrow with a width of 2 meters (even ditch), and 1000 kg of rotting organic fertilizer is used per mu. , the amount of seeds per mu is kilograms, and the sowing should be even.

For the spinach in eastern Guangdong is now over the age, of course it can grow next year, as long as the temperature and humidity are suitable, of course, it can be integrated with everyone.

The method of growing spinach in winter is as follows:

1. Fertilizer the idle and damp ground after harvesting the bai in autumn.

du, turn the ground, rake fine, hug zhi flat.

2. Germination. DAO: Soak in warm water for 24 hours before sowing, then scrub the mucilage off the seeds and dry them in the shade.

3. Sow seeds. Sowing seeds can be scattered, can also be sown, cover the soil 1-15 cm, and step on it.

4. When the humidity is less than 60%, it needs to be watered, and the watering should pay attention to the fact that the spinach can only be watered when the leaves are placed, and it is not easy to water before the seedlings emerge.

5. When the leaves grow to 25-35 cm long, they can be harvested. The spacing of the old root spinach should be 30-40 cm, after picking the large leaves, cover a layer with farmhouse fertilizer, and in the spring of the second year, if it is a sunny slope, the spinach will begin to sprout and grow before planting.

6. Post-wintering management: It takes 30 to 40 days to harvest spinach after wintering. When the spinach grows to 6 7 cm tall, the green water after overwintering is carried out on a sunny day, and the water is finely irrigated.

Apply a little nitrogen fertilizer appropriately. When the leaves grow to 20-30 cm long, they can be harvested one after another.

In the process of spinach planting, if the fertilizer and water ** are insufficient, the growth and development are stunted, and the vegetative growth area is small, spinach is prone to bolt fracture under the same temperature and light conditions. The optimal growth temperature of spinach is 20 and is not resistant to high temperatures. Once the temperature exceeds 25 degrees, it will grow poorly, with small, few leaves, reduced quality, and easy to sprout.

Spinach sprouts are also related to the purity of the seeds. Spinach is classified into absolute male plants, vegetative male plants, female plants, and monoecious plants. Sprouting occurs if the spinach seeds are not of high purity and are mixed with the seeds of an absolutely male plant.

Spinach cannot be short of water because it is a leafy green vegetable that has high water requirements. It can't be dried. Drought will prevent growth, premature senescence and budding.

In order to prolong the spinach sprouting time and improve the quality of spinach, it is necessary to do a good job in variety breeding. Good late-maturing varieties include Shanghai Yuanye, Guangzhou Chiwuye, Sichuan Dayuanye, etc. Spinach is a relatively hardy vegetable, so we should choose to sow it in cold, low-sun land.

Delaying spinach planting is also a practical way to avoid early moss. In general, it is better to sow seeds in October-November.

Spinach must be adequately fertilized before sowing. At the seedling stage, it can be chased with dilute human feces. When the plants are larger, the concentration can be increased and the seedlings can be removed for one fertilization to ensure strong seedlings.

Spinach can be grown year-round. Due to the different times when spinach is planted, the probability of sprouting is also different. In general, spinach planted in early winter will begin to sprout after the following spring due to the sudden increase in temperature and the sudden acceleration of spinach growth.

Spinach planted in early autumn is not prone to sprouting because the temperature continues to drop after spinach is planted.

Due to the short growth cycle of spinach, many people do not pay attention to the fertilization and watering of spinach when growing spinach. When soil moisture and nutrients are deficient, spinach can affect the growth of spinach stems and leaves due to insufficient water and fertilizer, thereby differentiating and transferring nutrients to the flower buds, resulting in spinach susceptibility to sprouting.

It may be because the temperature is too high, there is no timely cooling, no timely watering, and the varieties selected are not good, and the fertilizer is not selected well.

Because spinach grows very fast, it is particularly easy to sprout, which is also a law of growth.

Spinach is a very delicious vegetable, the nutritional value is very high, spinach can be planted all year round, according to the different planting time is divided into autumn spinach, overwintering spinach, spring spinach and summer spinach and other four types, and because of the different varieties, the sunshine length sensing is also different, so the planting yield and ** are not the same.

Make sure there is a suitable number of plants per unit area; Harvest early in spring and harvest more to ensure the unity of production and profitability. Therefore, planting at the right time is the key to the success of overwintering spinach planting, and the average temperature of the day can be reduced to 17 19 hours in each region according to local weather conditions. This is a good time to grow spinach.

Although the growth cycle of spinach is relatively short, spinach grown outdoors in winter will be disturbed by the ambient temperature and its growth will be retarded, and like most food crops, spinach also needs to encounter overwintering problems, even if spinach has good low temperature resistance. In recent years, the popularity of greenhouse planting, spinach has also become a key type of greenhouse winter production, because greenhouse is relatively good in thermal insulation and water retention, so it is slightly more important in spinach wintering.

As a leafy vegetable, the market demand for organic fertilizers is relatively large in the case of growth, especially the base fertilizer, which is very important for the growth of leaves and stems. Whether it is outdoor planting or greenhouse planting, in the case of spinach growth in winter, in order to accelerate its growth rate and resist cold damage, the main situation is that spinach itself must be relatively robust, which should fertilize spinach on time.

After the previous crop is obtained, it is necessary to subsoiling and raking the idyllic scenery, so that the soil is loose and rich, water retention and soil consolidation, and slightly acidic and alkaline soil is beneficial to the growth of spinach. Spinach is dominated by cultivating vigorous seedlings, and when 2-3 true leaves emerge, a seedling thinning is carried out for small seedlings with too high relative density, and a new high-lipid film is sprayed to prevent bacterial infection, improve the ability to resist disasters, improve the compressive strength of plant photosynthesis, and maintain the healthy growth of seedlings. It is not a unique drought, most of them are not watered, and the balance of growth on the ground and underground is maintained.

In the specific production, the key to the cold protection of spinach is the method of road covering, and there are two types of raw materials used, one is dry wheat straw, and the other is mainly agricultural mulch. From the point of view of cost, the cost of wheat straw or straw is lower, and in the later stage can be used as biological organic fertilizer to return to the field, from the actual effect, agricultural mulch film can not only lock the soil temperature outflow but also avoid the loss of soil layer moisture, heat insulation and water retention effect is better, which method must be used by the planters according to their own specific conditions to determine.
