If you want to stabilize the yield and increase the income of spinach, what are the precautions when

Spinach is a fast-growing green leafy vegetable, mainly eating young leaves, petioles, shallow stems or small portions, you can eat old stems, but the taste is reduced. Spinach has a short growing period and a fast growth rate, can be planted multiple times a year, and can also be planted with other crops, preferring a dense, cold and humid environment, and a mild climate. The spinach grown under these conditions has a high yield, so the planting season is autumn sowing and harvesting, spring planting and spring water or spring cropping in the second year of autumn planting.

Not suitable for planting during high temperature periods. Popeye is my favorite.

The sown vegetables grow relatively vigorously, the density is high, and the topdressing operation in the later stage is inconvenient, so it must be suitable for basic fertilizer. Wudang fully decayed organic fertilizer 4000 5000 kg, superphosphate 20 30 kg or compound fertilizer 30 40 kg, deep ploughing 20 25 cm, fully mixed fertilizer and soil, and then make bitter fruit or square grass for broadcasting, to prevent excessive rainfall.

Spinach is a leafy vegetable, and the autumn rain is dominated by fast-acting nitrogen fertilizer. The seedlings have 4 or 5 leaves, and can be harvested according to the water for wizard 20 25 kg or urea 10 15 kg or so, or completely putrid human feces or thin manure according to the water, and can generally be harvested 1 2 times during the growth period.

Spinach is a food that people often eat at the dinner table, and spinach is highly nutritious. Some people think that spinach is one of the most iron-rich vegetables in the vegetable category, and spinach is a top dish for human implants. So whether people grow spinach at home, they can see the shadow of spinach in the supermarket or vegetable garden.

Spinach is a leafy green vegetable that housewives are passionate about.

Spinach is delicious and nutritious, is spinach easy to grow? What fertilizer is good for spinach in autumn? Let's plant spinach with these questions in mind.

Spinach is generally sprinkled. Spinach is planted in late August to early September, when the temperature is just right for spinach to grow. Spinach is generally sown directly and live.

That is, it is enough to sprinkle spinach seeds evenly in the prepared vegetable garden directly with your hands. But tidy up your spinach garden before sowing.

The vegetable garden should be deep and flat, and the most important thing is to put fertilizer on the soles of the feet, and the bottom fertilizer should be made of farmhouse manure that is ripe through the farm. This kind of manure has a long-lasting effect, the fertility is relatively mild, and it does not burn roots and seedlings. The soles of the feet are fat, they can seep water, and they can sow seeds when the water dries.

Spinach seeds can germinate within a week, after germination, the seedlings should be watered according to the situation when they grow, when the soil is too dry, and gently when watering.

Spinach seedlings grow two or three true leaves can be topdressing spinach, and when topdressing begins, farmyard fertilizer is the main thing, and farmer's manure should be used at this time. The manure is relatively soft and does not burn the seedlings.

When spinach grows to the middle and late stages, the stems and leaves of spinach are not large and small, and they can be topdressed with ether water, urea is a fertilizer with higher efficiency, spinach will soon absorb the fertility of ether, and the long stems of spinach will absorb coarse leaf fertilizer, and the spinach with green color will absorb it.

Ammonium nitrogen fertilizer should be used with caution. Spinach is sensitive to ammonium nitrogen fertilizer, and the production season of overwintering spinach is at the junction of autumn, winter and spring. The soil temperature is low. Soil digestion is very weak, so less ammonium nitrogen fertilizer is used and more nitrate nitrogen fertilizer is used.

Pay attention to the type and amount of fertilizer used and the time of use. To increase the yield of spinach, it is necessary to be able to apply fertilizer at the right time, and control the amount of fertilizer, and pay attention to the use of fertilizer that can increase yield.

The first point is to talk about the bottom fertilizer, because the growth period of spinach is relatively long when it is harvested, so it is necessary to do a good job of base fertilizer before sowing, because the soil fertility will decline rapidly when the temperature is low, which will make the spinach lack nutrients. When applying the base fertilizer, it is good to be moderate, not too much, otherwise it is easy to grow the phenomenon, the bottom fertilizer is actually the best choice of compound fertilizer, which can help to supplement various elements, and must be watered, so that the root system can quickly absorb nutrients, and then grow well.

The main reason is that I want to eat pure natural Xinxiang spinach, so I will not fertilize, although the spinach looks not very good-looking and does not grow big, but it tastes unique, it is also very delicious, I don't want people to plant spinach in the greenhouse, spinach high yield has a lot to do with the selection of varieties, seed treatment will be carried out before sowing, spinach will be soaked for 12 24 hours, and then placed in a cool place for spring sprouts, which is conducive to seed germination rate. When germinating, observe the seeds, keep the seeds moist, and wait for the seeds to germinate before sowing.

The amount of water and fertilizer absorbed is relatively large, at this time it is necessary to carry out top dressing, 15-20 kg of ammonium sulfate can be used per mu as top dressing, it should be noted that the growth cycle of spinach planted in early spring is short, so it is necessary to supplement nitrogen fertilizer to promote the rapid growth of spinach leaves and prolong the sprouting. As a result, the tips and margins of spinach are yellow-brown, the roots are brown, and the growth stops, and even dies. Spinach is a fast-growing green leafy vegetable, which needs more nitrogen fertilizer during the growth process, and if there is too much nitrogen fertilizer, it will lead to poor leaf and cold resistance, so it is appropriate to apply phosphorus fertilizer.

When the spinach sprouts begin to grow, water them once, and the amount of water should not be large. Spinach will soon reach a rapid growth period after returning to green, and should be given enough fertilizer water, watering water should be larger, and fertilizing once with watering. Generally, in the middle and late stages of growth, the amount of fertilizer and water absorbed by spinach begins to increase, and at this time, about 15 to 20 kg of ammonium sulfate can be applied to each acre.

Because the growth cycle of spinach in spring is relatively short, sufficient nitrogen fertilizer can make spinach leaves grow vigorously.

It is mainly high furrow or flat furrow. For wintering spinach, choose soil with sufficient fertility, deep soil layer and good fertilizer and water retention. Compared with other seasons, the amount of basal fertilizer should be appropriately increased, and the soil should be deeply turned so that the soil and fertilizer can be fully mixed to promote the emergence of seedlings.

There is no need for top dressing during the overwintering stop growth period. In early spring, the growth period is 30-40 days, when the spinach leaves turn green and the heart leaves begin to grow, you can water 1 time. After spinach enters the vigorous growth period, it should be topdressed in time, combined with watering, 10-15 kg of ammonium sulfate per 667 square meters.

1. Apply sufficient base fertilizer. Big-leaf spinach has a short growth period, is a fast-growing vegetable, the whole growth period has high requirements for fertilizer, insufficient fertilizer will cause the leaves to look bad and easy to flower, and the fertilizer effect of organic fertilizer is long, can meet the needs, so the application of sufficient base fertilizer is the key. 2. Apply top dressing in time.

Spring large-leaf spinach in the early stage of growth, generally do not need to apply fertilizer water, in order to absorb nutrients in the soil, but in the middle and late stages of growth, the amount of fertilizer absorbed increases, 15-20 kg of ammonium sulfate can be applied per mu, in addition, due to the short growth period of large-leaf spinach in spring, sufficient nitrogen fertilizer can make the leaves grow vigorously and delay the sprouting period. 3. After the large-leaf spinach seedlings are unearthed in autumn, when 4-5 true leaves grow, 2-3 times of fast-acting nitrogen fertilizer should be applied in stages, and 20-25 kg of ammonium sulfate or 10-12 kg of urea should be applied per mu to promote the thickening of the leaves, increase the yield and improve the quality.

Spinach leaves after watering a manure, top dressing to do the first light and then thick, the early stage should be more farm fertilizer, in the vigorous growth period to top dressing 2 to 3 times, can choose urea per mu about 10 kg.

About two weeks before the spinach harvest, a fast-acting nitrogen fertilizer should be applied, and gibberellin can also be appropriately treated to improve yield and quality.

When fertilizing spinach, it is necessary to pay attention to the application of sufficient basic fertilizer before sowing, keep the soil fertile, nitrogen fertilizer, phosphate fertilizer and potassium fertilizer should be properly matched, and strengthen fertilizer and water management after overwintering and returning to green, and strictly control the top dressing time.

Spinach is an annual plant in the Chenopodaceae family, and spinach is native to Saudi Arabia. Spinach is a low-temperature resistant vegetable and fruit, with short growth period, strong adaptability and high production, and is the main vegetable and fruit in winter and spring. Nutritious, delicious and one of the main leafy greens.

Spinach has a wide range of adaptability, plant sizes can be eaten, can be planted all year round, can be supplied for anniversaries, spinach is mainly dominated by autumn seeds, sowing from mid to late August to early to mid October. In order to better increase the delivery time, installment sowing is often used in manufacturing. Spring spinach was planted from January to April, summer spinach was planted from May to July, and autumn spinach and winter spinach were planted from August to December.

It is seed treatment, the seeds of spinach have thorns, often many seeds stick together, the exocarp of spinach seeds is hard and solid and rotular, the water is not easy to permeabilize, and the seedling rate of spinach is harmed, the seeds and the soil layer are not tight, the spinach exocarp is harder and thicker, the water absorption is poor, and the germination is slow, therefore, in order to deal with the problem of low germination rate of spinach seeds, it is necessary to beat with a stick before sowing, and the seed exocarp is smashed and rubbed to dissipate the thorns. After soaking the seeds in cold water for 12-24 hours, scoop them up with a damp cloth bag to promote teeth at room temperature, and sow seeds after 3-5 days of leakage.

It is selected to sow at a suitable temperature standard, the minimum temperature of spinach seed germination is 4, the optimal temperature is 15-20, under the appropriate temperature standard, spinach seeds germinate quickly, and the seedling rate can exceed 90%. When the ambient temperature reaches 35, the emergence rate is less than 20%, therefore, spinach sowing must be selected above 4 and 25 key sowing can improve the germination rate of spinach. It is the selection of planting soil, the soil pH of spinach planting is 6-7, if the soil layer pH is lower, the seed germination is not uniform.

Spring spinach is generally sown at the average temperature of 4-5 in spring, and spring spinach is generally planted in 1-4 months, and it is sown early and <> in warm areas

In general, the seeds are sown around the time of Qingming. The temperature of spring spinach is low in the early stage, the germination of seeds is slow, the temperature rises in the middle and late stages, the sunshine increases, the nutrient growth period of spinach is short, the number of spinach leaves is small, it is very easy to sprout, and the production is low. Spring spinach because of the short growth period, to choose the round leaf spinach species planting, before sowing to carry out soaking seeds to promote teeth, sowing method to choose wet sowing method, that is, before sowing water, water infiltration after laying a layer of subsoil, and then sowing and covering the soil, this kind of sowing method is beneficial to maintain the soil layer moist and promote the excavation of seedlings.

Increase the sowing amount, and the sowing amount of 1 mu is around 7 kg. Because the spring spinach growth period is short, when about 10 days after germination, you have to see the seedling fertilization, promote the growth and development of the seedlings, 1 mu of urea solution 15 kg or so, and then top dressing 1-2 times, while maintaining the soil layer moist. In the spring, the weeds in the field grow and develop relatively quicklyAfter budding, hoeing should be carried out in time.

Spinach plants are 15-18 cm tall and can be picked when the leaves are sufficient. Picking is carried out in batches, first evenly remove a part of the large seedlings, and continue to fertilize the remaining part of the weak seedlings, and then pick them when they grow up.

When planting, we must pay attention to the pH of the soil, whether the climate is suitable, whether the light coefficient is sufficient, and whether the soil fertility is sufficient; If you want to increase the yield, try to use high-quality spinach seeds, you can choose clay soil to grow spinach, this soil is very rich in minerals, which is very helpful for the increase of spinach production.

Pay attention to planting density, but also to planting depth, to pay attention to soil protection, to pay attention to disease states, and to pay attention to spinach rotten. You can observe the situation of spinach in time during the planting process, and pay attention to watering and fertilizing the spinach, so as to increase the yield.

It is necessary to pay attention to fertilization, watering, and the selection of varieties, and to better improve the yield, we must pay attention to the breeding environment and pay attention to observation.

Be sure to pay attention to the temperature, the temperature can not be higher than 30, and then we must ventilate more, we must improve the loose air permeability of the soil gas, and then we must soak in water before sowing, and the fertilizer can choose nitrogen fertilizer.

1.The amount of organic fertilizer should be sufficient.

In spinach cultivation, the use of organic fertilizer is usually ignored, and there is a widespread phenomenon of less or even no application. If the organic fertilizer of spinach is used higher, the amount of organic fertilizer can be reduced, but the growth time of overwintering spinach is relatively long, in order to avoid the middle and late stage of spinach fertilizer, it is recommended to use sufficient organic fertilizer as the base fertilizer.

2.Spinach is grown on acidic soil, and the same type of fertilizer should not be sprinkled.

Spinach is very demanding on soil quality, and it is a plant that does not like acidic soil very much. According to the experiments of experts, it is found that the pH value of the soil layer that is most suitable for planting spinach should be kept in the middle, and too low or too much is not suitable for the growth of spinach. When the pH value is less than that, that is, when the soil layer is too acidic, the spinach will stop growing and it is very likely to die.

Therefore, when planting spinach, you must choose the right land. If the environment is only acidic soil, do not add the same kind of fertilizer to spinach, which will expand the pH of the soil and is not conducive to the growth of spinach. On the whole, spinach grown on acidic soil should be supplemented with alkaline fertilizers.

Alkaline fertilizers can neutralize the acidity of the soil layer and create conditions for spinach to grow.

3.Top dressing points.

The best time for spinach topdressing should be before its flowering period, and the topdressing before the flowering period arrives can reasonably delay the flowering period of spinach, which is conducive to improving the pollination and fertilization rate of spinach, increasing the production and quality of spinach. Spinach is very sensitive to the transformation of nitrogen fertilizer, which is divided into ammonium nitrogen and nitrate nitrogen, and the ground temperature has not warmed up after wintering, so the digestion and absorption of ammonium nitrogen is not very obvious. Therefore, we should reduce or even stop the use of ammonium nitrogen when topdressing nitrogen fertilizer, and then topapply nitrate.

4.Add less ammonium bicarbonate and ammonium chloride to spinach.

Vegetables and fruits such as spinach do not like ammonium very much, and there is no problem with a little bit, but if you sprinkle too much fertilizer, spinach is very easy to burn seedlings. Therefore, it is recommended that when planting spinach, it is best to choose nitrogen fertilizer, and pay attention to the temperature of the soil layer when fertilizing. If the ground temperature is too low, the fertilizer cannot be converted into nutrients in time, and the spinach will not be able to absorb sufficient nutrients.
