Do you need to cover the mulch film to grow spinach Can spinach seeds be sprinkled directly in the g

Spinach is generally sown by seeding. When sowing seeds in summer and autumn, the seeds should be soaked in water for more than 12 hours a week before sowing, and then stored in a place with an ambient temperature of only 4 for 24 hours, and then germinated at a temperature of 20 25 for germination, and then the seeds can be sown after germination. Spinach in spring and winter does not need to go through these treatments and can be sown directly.

After sowing, remember to sprinkle a layer of plant ash.

Shade and hydrate. <>

After sowing, you can water a little, remember not to water too much. In summer and autumn, the seeds should be covered with straw or shade nets, so as not to affect the development of seeds due to the intensity of the sun, and the soil should be kept warm and moist. Spring and winterSowing spinach, because of the lower temperature, generally toCover with plastic filmIt is used to maintain the temperature and promote the development of seeds.

Spinach cultivation techniques.

Seeding time. Spring spinach can be sown when the temperature rises above 5 °C after the beginning of spring, March is the appropriate time for sowing, summer spinach is sown in stages from May to July, autumn spinach is sown from August to September, and overwintering spinach is sown from mid-October to early November. Spinach usually germinates in 2 to 3 days after sowing.

Prepare the land for furrowing. Choose loose and fertile, water and fertilizer retention, and good drainage and irrigation conditions. 4000 kg of decomposed organic fertilizer and superphosphate are applied per mu during land preparation.

40 kg, leveling and fine, winter and spring should be done high furrow, summer and autumn should be flat, furrow width to meters.

Sowing seeds and raising seedlings. Spinach plots are generally sown. Summer and autumn sowing is to soak the seeds in water for 12 hours 1 week before sowing, put them in a well or in a refrigerator or refrigerator for about 4 hours for 24 hours, and then promote germination under conditions of 20 to 25, and sow seeds after germination in 3 to 5 days.

Dry or wet seeds can be sown in winter and spring. 3 to kg per mu are sown.

After pouring the bottom water on the furrow surface, sow the seeds, lightly rake the topsoil with a tooth rake, so that the seeds are sown into the soil, and cover the furrow surface with a layer of plant ash.

After sowing in summer and autumn, it should be covered with straw or covered with a small arch to prevent high temperature and heavy rain. Frequently keep the soil warm and moist, 6 to 7 days can be seedlings, winter sowing temperature is low, then cover the furrow with plastic film or shade net insulation to promote the emergence of seedlings, after the emergence of seedlings.

Field management. Autumn spinach produces real leaves.

After pouring 1 time of manure cleaning water; After 2 true leaves, combined with seedlings, weeding, top dressing first light and then thick, and more decomposed manure was applied in the early stage; Top dressing 2 to 3 times during the peak growth period, urea per mu each time.

5 to 10 kg.

The soil remains moist after winter spinach planting. When there are 3 to 4 true leaves, the water should be controlled properly to facilitate overwintering. For 2 to 3 true leaves, the seedling spacing is 3 to 4 cm.

According to the seedling condition and weather, water and fertilizer were applied top-notch, and the feces and urine of ripe people were mainly decomposed. Frost and ice and snow weather should be covered with plastic film and shade nets for insulation, which can be covered with small arches. After the beginning of spring, choose a sunny day to apply well-rotted light manure water to prevent early sprouting.

Spring spinach should be covered with plastic film in the early stage of insulation, which can be directly covered on the furrow surface, and the film will be removed after the emergence of the film or changed to a small arch cover, and the small arch shed will be covered by day and night, and the rain cover will be covered by sunshine, so that the seedlings can see more light, refine more seedlings, and time seedlings. Top dressing fertilizer water, in the early stage, apply lightly and diligently with decomposed human and animal manure, and apply fast-acting nitrogen fertilizer in the later stage, especially 15 days before harvest.

After the emergence of summer spinach, it is still necessary to cover the shade net, cover the shade in the sun, cover it late and cover it early, so as to facilitate cooling and heat preservation. Watering at the seedling stage should be done in the morning or evening with light water.

Pour frequently. After 2 to 3 true leaves, fast-acting nitrogen fertilizer is applied twice. Water should be poured after each fertilization application to promote growth.

If you plant spinach and cover it with mulch, you will eat spinach very early in autumn. It's okay not to cover it with mulch, because spinach is hardy and doesn't die in winter.

It is not possible to plant spinach seeds directly in the ground. It is difficult for spinach seeds to germinate directly on the ground, if the spinach seeds are sprinkled directly into the ground, and a thin layer of soil is sprinkled on top at the same time, then the probability of germination will be relatively high.

Why do you need mulch to grow vegetables in summer?

Summer is a great time to grow vegetables, but many people have the same problem, which is that vegetables grown in the summer do not grow fast enough and are susceptible to the effects of climate change. In order to solve these problems, many people choose to cover them with mulch when planting vegetables. So, why do you need to cover vegetables in the summer?

The role of covering the mulch.

Mulch film has many functions, the most important of which is heat preservation and moisturizing. Temperatures are high in the summer, but relatively low at night, which can easily lead to fluctuations in soil temperature. Covering the plastic film foundation can prevent the heat and gas loss from the ground, and then keep the soil temperature relatively stable.

At the same time, the mulch film can also prevent the evaporation of water, reduce the frequency of watering, and maintain the moisture of the soil, which can make the plant acacia modification get a better growth environment.

Cover the choice of mulch.

There are some issues that need to be paid attention to when choosing a mulch film. First of all, it is necessary to choose materials with good air permeability, such as plastic films and natural fiber materials that can lead to breathability. Secondly, you need to pay attention to the thickness of the plastic film, and you can choose the thickness of the plastic film between the to.

Precautions for growing vegetables.

Although mulching can provide a better growth environment for plants, there are still a few things to pay attention to. First of all, mulch film is not a panacea, and there is no guarantee that all vegetables can adapt to the environment of mulching, so you need to pay attention when choosing vegetables to grow. Secondly, when covering the mulch, it is necessary to give the plants space for ventilation, and to clean up the weeds and dead branches below in time to maintain the permeability of the soil.

Finally, the summer environment is windy and rainy, and the lack of moisture from artificial irrigation after covering with mulch film may lead to plant death, so it is also necessary to check the soil moisture regularly to ensure proper watering.

Advantages of mulching film.

The advantages of mulching are obvious, first of all, it can improve the yield and quality of vegetables, and at the same time, it can also save water resources. In addition to this, mulch film can also reduce carbon emissions and thus protect the environment. Therefore, it is a good choice to cover with mulch when planting vegetables, which can improve the efficiency of growing vegetables and make your own contribution to environmental protection.

Because the plastic film can not only improve ground temperature, water retention, soil retention, fertilizer conservation and improve fertilizer efficiency, but also has many functions such as weedicial, pest prevention, drought and flood prevention, salt inhibition and seedling protection, improvement of light and heat conditions near the ground, and hygienic and clean products. For those newly unearthed seedlings, it has the effect of protecting the roots and promoting growth.

In the three northern regions of China, the factors restricting agricultural development such as low temperature, lack of rainfall, drought and barrenness, and short frost-free period have strong pertinence and applicability, and also play a role in planting second-season rice seedlings and cultivating a variety of crops.

After mulching cultivation, the temperature and moisture status of the soil and near the ground can be improved, and the soil temperature can be increased, soil moisture can be maintained, soil properties can be improved, soil nutrient status and fertilizer utilization efficiency can be improved, light conditions can be improved, and weeds and diseases and insect damage can be reduced.

1.Thermal insulation and warming, promote the decomposition and release of soil nutrients.

2. Moisturize and improve survival rate.

The soil moisture of the field, except for irrigation, is mainly due to rainfall. After covering the film, on the one hand, the evaporation of soil moisture is reduced due to the barrier of the plastic film, and the loss is slow; And after forming water droplets in the membrane, they fall into the soil surface, which reduces the loss of soil moisture and plays a role in conserving soil moisture. On the other hand, the plastic film can also prevent a large amount of rainwater from entering the ridge when the rainfall is too large, which can play a role in preventing waterlogging.

3.Promotes growth and development.

The application of plastic film mulching, the temperature and humidity of the soil increase, which is conducive to early growth and rapid development, and promotes the growth and development of plants. The growth period of mulching is shortened to about one week compared with that of non-mulching.

4.Reduce the damage of weeds and aphids.

Mulching can inhibit weed growth. Generally, the weeds covered are reduced by more than one-third compared with those without mulching, and the effect of weed control is more obvious if combined with herbicides. After spraying herbicides, the number of weeds covered with film was reduced compared with those without film.

Mulch film has a reflective effect, and can also partially repel aphids, inhibit the breeding and reproduction of aphids, and reduce the damage and disease spread.

5 Negative effects of mulching.

Plastic film mulching has both positive and negative effects, for example: although plastic film mulching has the effect of water retention, but it hinders the external precipitation into the ridge body, and if the corresponding ridge type or other measures are not taken in some areas, it may lead to water deficit in the long term of tobacco plants, affecting the normal growth; If it encounters continuous rainfall, it is easy to cause serious water stains, which makes the soil permeability deteriorate and the evaporation of water is blocked, which also affects the growth of tobacco plants. Therefore, combined with the actual local production, it is the basis for the success of plastic film mulching planting to seek advantages and avoid disadvantages, formulate feasible plastic film covering production technology, make full use of the role of plastic film, and take corresponding supporting technical measures.
