What is the reason for the slow germination and uneven emergence of spinach after sowing?

It must have something to do with the choice of its seeds.

So let's look at it, what is the structure of its seeds? In fact, its seeds are different from other vegetable seeds in that their seeds have a hard shell on the outside. If our seed is to sprout, then it has to penetrate this hard shell, which is very difficult.

Therefore, this is also the situation that we find in our daily life that when we plant it, it germinates and emerges very well or unevenly.

Then to solve this problem, it is also very simple, we now know the reason, then we can find a way according to this reason. Because of its seed, we need to prepare in two ways.

First of all, the first aspect is that we need to choose better quality spinach seeds. High-quality spinach seeds, in fact, are not so difficult to find, as long as we go to the store to choose, we can choose a very suitable seed for our own planting. In the past, when we planted it ourselves, we liked to plant some of its seeds that we left, but there were some problems in this, because the seeds we kept were actually after many years of continuous cropping.

Its quality is not so good.

The second point is that we need to process its seeds after we have selected them. We process its seeds in order to get rid of the hard shell on the outside of its seeds. The method of processing is also very simple, first of all, we can directly take its seeds and then rub it, and rub the outer layer of hard shell to soften.

It's better to be able to destroy it. Then we soak the seeds in the water we have prepared in advance, which is a method we commonly use called soaking. When we are soaking, we must pay attention to the time, generally half a day is enough.

If we take care of its seeds, we can basically improve our own emergence rate.

In the past, they all loved to use their own seeds to plant, with the improvement of technology, seeds have become the main purchase, the mode of single seed retention has become less and less, their own seeds are easy to appear seed aging, quality decline occurs, the purchase of seeds has also become the mainstream, buy seeds, to choose the seeds suitable for the current season sowing, to select the production date is relatively close, spinach seeds have seasons, purchase errors are easy to appear slow seedlings or seedlings phenomenon, it is very important to choose the right seeds.

First: the seed selection is not good, the maturity of the seed is not the same, the second: the light is uneven, and the third: the moisture, temperature and other conditions are uneven.

Related to seedlings, sowing seeds that are different from the season will affect the germination rate of spinach, and there will be a possibility of slow germination.

Under normal circumstances, if the spinach is well maintained after sowing, that is, the soil is moist, and at the same time ensure that the spinach seeds are fresh and <>

3-5 days can germinate.

Spinach usually germinates in 2 to 3 days after sowing.

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.

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 germinate 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 clean manure water;After 2 true leaves, combine seedlings, weeding, top dressing first light and then thick, and apply more decomposed manure in the early stageTop 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.

After spinach is planted, it generally emerges within 2 to 5 days. When planting spinach, it is necessary to choose a small amount of coarse sand, well-drained, loose and fertile garden soil, select suitable seeds and then sow them after low temperature treatment, and remember to spray watering and thin fertilizer after germination, accept full sunshine and do a good job in frost and pest control.

Normally, it can germinate in about three days, if the temperature is right, the moisture is also suitable, it will be able to germinate quickly, if it is not satisfied, then it may have to be postponed for 2 or 3 days.

How many days can germinate after sowing, this should take half a month, this should be able to germinate, and this germination effect should still be very good, can better carry out some growth, I think this growth should be very good.

<> spinach is not heat-tolerant, if the temperature is higher than 25 after it emerges, then it will not grow long. Spinach needs plenty of light after it emerges, and if it doesn't have enough light, spinach won't grow long. It may also be caused by insufficient water and nutrients, and it is necessary to let it have sufficient water and fertilizer during the spinach growing season.

1. The temperature is too high.

Spinach is a hardy but not heat-tolerant plant, its most suitable growth temperature is between 15-20, if the temperature is too high, it will grow poorly, so that it will not grow after the emergence of seedlings, then we need to cool down the spinach in time, it is best to control the temperature below 25.

2. Insufficient light.

Spinach is a long-day plant, after it emerges, if the light is insufficient, then it does not grow, so when planting vegetables, it needs to be exposed to sufficient light, so that it can grow vigorously, but pay attention not to let spinach be exposed to the sun, otherwise it is easy to wither.

3. Insufficient moisture.

Spinach has a high demand for water, if the water is insufficient, then spinach will also appear after the emergence of the phenomenon of not growing, at this time you need to replenish water for spinach in time, it is best to keep the soil slightly moist, pay attention not to let the soil have water in the production, otherwise spinach is prone to rotten roots.

4. Insufficient nutrients.

The growth of spinach needs sufficient nutrients, if the nutrients are insufficient, then it will also appear that the seedlings do not grow after the phenomenon, so before cultivating spinach, it is necessary to apply basal fertilizer in the soil to improve the fertility of the soil, and after the spinach emerges, it is necessary to apply several thin rotting fertilizer water to facilitate the growth of spinach.

Spinach can germinate in 3-5 days after sowing, and spinach fields are generally sown. In summer and autumn, the seeds are soaked in water for 12 hours one week before sowing, placed in a well or processed in a refrigerator or refrigerator at about 4 °C for 24 hours, and then germinated at 20-25 °C, and sown after germination. Dry or wet seeds can be sown in winter and spring.

Kilograms of sowing per mu.

Spinach sown in summer or early fall and harvested in autumn. Autumn spinach sowing temperature is in the average daily temperature of about 20 period, summer and autumn sowing in 1 week before the sowing of the seeds soaked in water for 12 hours, placed in the well or in the refrigerator or refrigerator at about 4 °C for 24 hours, and then in the condition of 20-25 °C to promote germination, after germination sowing.

Spinach will germinate three to five days after sowing if the external conditions are good after sowing. In summer and autumn, the seeds should be soaked in water for more than 12 hours a week before sowing, and placed in a well or in a refrigerator at a temperature of 4 degrees Celsius for 24 hours, and then germinated at 20 degrees Celsius to 25 degrees Celsius, and sown after germination. In spring and winter, dry seeds can be sown.

Spinach, also known as Persian cabbage, red root cabbage, parrot cabbage, etc., belongs to the genus Spinach in the Chenopinaceae family, and is an annual herbaceous plant. The plant can be up to 1 m tall, the roots are conical, reddish, less white, the leaves are halberd-shaped to ovate, the branches are not destroyed, and the whole margin or has a few tooth-like lobes. There are many types of spinach, which can be divided into two varieties, thorny and thornless, according to the seed form.

In order to germinate faster after planting, it is necessary to choose seeds that are ripe and not damaged before planting. The soaking method can be used to sift all the seeds in water, and then discard the shriveled, blackened or damaged ones.

The seeds are screened and then soaked. The hydrogen peroxide solution can be treated once and then soaked in warm water for about 30 to 50 minutes. If it is a low temperature environment, it is necessary to extend the soaking time to allow the seed coat to fully absorb the water.

When planting, choose soil with good air permeability, so that the seeds can germinate as soon as possible. The soil can be mixed with sand, chaff ash and nutrient soil, and then mixed with an appropriate amount of compound fertilizer to improve the content of the nutrient late. Note that it is not possible to use alkaline soil, which will affect germination.

Once the seeds have been treated, they can be sprinkled on top of the soil and covered with a layer of wet grass to moisturize them, taking care to control the temperature. The temperature is best between 15 degrees and 20 degrees, during which the soil is observed to be dry and wet, and when it is found to be dry, it will be replenished in time to keep it slightly moist, and it will be able to sprout in about two weeks.
