What are the precautions for planting cucumbers during the seedling period?

Seedlings, cucumber temperature-loving, spring cold, and low ground temperature are the main obstacles to cucumber cultivation, and seedlings should generally be raised. Cucumbers grow fast, meals are slow, and it is best to use Yang Chaoyue meat. In order to select seeds and soak them for germination, carefully select the seeds before sowing, choose fresh and full seeds, dry them first, so that the buds germinate evenly, then add the seeds in hot water at about 55 degrees, stir for 10 minutes, reduce to room temperature, soak for 5 6 hours, wash them, and germinate them in a warm place at 25 soybeans and 30 degrees.

It is necessary to do a good job of sowing. The seedbed should be watered with water from the bottom of the foot before sowing. Because the seedlings can ensure the demand for water, they can no longer be watered during the general seedling period, so it is necessary to prevent the growth of roots and seedlings.

It is necessary to choose excellent varieties that are suitable for the local consumer market. The excellent varieties of northern Miko type include Changchun Mi Needle, Chen Chun Mi Needle, Xintai Mi Needle, Shandong Mi Needle and so on. In South China, you can choose Zhaoqing No. 2, Zhengzheng Qiu No. 206, etc., and consult local seed dealers or agricultural technology departments.

Soak the cucumber in water, highlight Cui'er, soak the cucumber in hot water at 52 to 55 degrees for 30 minutes, soak and mix, remove it and rinse it with clean water. Soak in clean water for 6-8 hours and wrap in wet gauze. Put it in the germination at about 26 30 degrees to promote germination, and pay attention to the moisturizing of the seeds.

About 2-3 days or so, half of the seeds can be sown after exposure.

Cucumber seedlings can be used as blood-spotted seedlings, as vegetative feet or bucket field seedlings. The meat is made as much as possible with the blended nutrient soil, and the perlite:vermiculite ratio is a standing ordinary recipe of 23360133601, or it can be prepared separately.

The soil is used as nutrient soil, the soil must be fertile, well ventilated, and organic fertilizers are generally added to the pastoral soil, and chemical fertilizers must not be used in the seedbed. It is necessary to prevent chemical fertilizers from burning the roots.

After finishing or filling the seedlings, plugs and other nutrient soil, pour water, seep water, and re-cover the seeds in the plug or the seedlings on the centimeter of nutrient soil. Cover it with mulch film or erect arch film for heat preservation and moisturizing. It is best to keep the temperature 24-30 degrees.

After the cucumber seedlings come out, the mulch film will be removed. The arch does not go, but the ventilation management should be strengthened.

After the cucumber seedlings come out, we should pay attention to exercising the seedlings, the seedlings should be kept moist, not too much watering, and the ventilation management should be strengthened to prevent the apprentices from growing tall seedlings, and not to appear rigid seedlings. At the seedling stage, potassium dihydrogen phosphate solution can be sprayed for top dressing.

The allocation of nutrient soil in the seedbed is mixed with clean soil raw soil, decaying organic fertilizer, potassium sulfate compound fertilizer, grass and wood, and uniform allocation of nutrient soil. After mixing, put it in the seedbed. Sow in the morning on a sunny day, pour water on the ground the day before sowing, and sprinkle water after sowing.

Before germination, the bed temperature should be maintained at about 30 °C. At the same time, a new high-lipid film is sprayed to prevent germs. Reasonable dense planting.

The general distance between plants is 25-30 cm, and the row spacing is 50-60 cm. To eat formally in the morning of the "sober hair of the pubic tail".

In the seedling period every half a month is to add fertilizer, fertilizer selection organic fertilizer, can well promote the growth of plant rhizomes concentration is not too high, otherwise the phenomenon of root burning will occur, proper watering, keep the soil moist, more plant ventilation and increase light.

After the emergence of seedlings, the watering time should be selected at 9-10 o'clock in the morning, after watering at 9-10 o'clock, the temperature will gradually rise, and the water on the surface of the substrate can be evaporated in time by releasing the air, so as to reduce the humidity and effectively reduce the outbreak of diseases.

When about 80% of the seeds break the soil and emerge from the seedling, the temperature should be appropriately reduced, 20 25 during the day and 13 16 at night to prevent the high temperature from causing the seedlings to grow. Because the flower bud differentiation of cucumber is early, the flower bud differentiation begins before the first true leaf, and the root regeneration ability of cucumber is weak, once the root is broken, it is difficult to recover, so when the cotyledons are flattened, the seedlings should be moved immediately, which can not only hurt the roots, but also does not affect the flower bud differentiation.

First of all, it is necessary to water in time, we must ensure the adequacy of water resources, and it is necessary to grasp the best watering time, we should pay attention to different periods, ensure the right fertilizer, and to improve the yield, we should ensure the fertility of the soil, and do a good job in soil drainage.

As far as I know, cucumber light management is very important after emergence, and if the light is too strong in summer, you can use shade nets to shade the sun in the afternoon.

Cucumber seedlings are sown in early spring, from January to March, when the climate is mild and the growth rate is fast, which is very conducive to germination. The other time is from June to August in summer and autumn, when the climate is cool and pleasant, which is also conducive to the growth of vegetables. According to the local climatic conditions, select the right seeds, ensure the quality, screen the seeds, and pick out the wilted and damaged seeds.

Once the seeds have been selected, they cannot be sown right away and need to be treated. Soak the seeds in hot water, keep the temperature at about 55, remove them after about half an hour, and then sow the seeds. Prepare the seedling tray, which can be mixed with peat soil, perlite and vermiculite in the same proportion to ensure fertility, looseness and ventilation, and add organic fertilizer at the bottom.

Once the soil is ready, water is poured into it, sowing seeds as needed, and covering with thin soil. Growth HabitsCucumbers like warmth and are not cold tolerant.

The suitable temperature for growth is 10-32, generally 25-32 during the day, and 15-18 at night. The optimal ground temperature is 20-25, and the minimum temperature is about 15. The temperature difference between day and night is optimally 10-15.

Cucumbers in 35 poor photosynthesis, in 45 appeared high temperature barriers, in -2-0 frozen to death. If hardened at low temperatures, they can withstand 3 low temperatures. Fertilize the seedbed before January, disinfect the greenhouse with chemicals, plough it, cover it with agricultural film for a week, and expect sowing.

60% soil and 40% organic fertilizer were mixed, 180 grams of methaloxim manganese zinc per cubic carbendazim were mixed, sifted, and covered with agricultural film for 24 hours. Soak the seeds in 55 warm water for 15-20 minutes, and soak the seeds in warm water for 30 hours for 6-8 hours.

Do a good job of seedbed seedbed general width and length according to the number of seeds to determine the seedbed soil the day before sowing dig out the seedbed soil, and then fill the seedbed soil, step on it with your feet, and pour water from the bottom into it. Sprinkle with a rake with nutrient soil and cover with poisoned soil. Sprinkle the seeds around and then in the middle, then flatten them with a shovel and sprinkle rat poison around them to build a shed.

After sowing, the temperature in the shed should be controlled at about 32. Generally, 3 days after sowing, 1 3 seedlings will emerge. When the emergence rate reaches 70%, the temperature drops to 18-22 to prevent the seedlings from escaping at high temperatures.

Set the sowing point according to the row spacing of 50 60cm and the plant spacing of 30cm, dig a 20 cm deep hole and fill it with water, soak half of the soil in water, fill the hole, and sow 2 seeds; Cover soil 1-2 cm; Cover with plastic film. After the cucumber seedlings are unearthed, they need to break the membrane in the morning and evening to prevent the membrane from scalding the seedlings. Replenish seedlings, thin seedlings, and check seedlings in time.

The cucumber has two leaves, and when there is a heart, it will be thinned and fixed; Replenish the seedlings in time when the seedlings are missing. Pruning, topping, branching, flower plucking, thinning of excess branches, removal of apical buds of growing branches, removal of all side buds. Remove old and diseased leaves.

remove excess deformed flowers and fruits; In the case of nutrient deficiencies and stress, plant nutrition should be improved, plant growth regulators should be sprayed, and flowers and fruits should be protected.

Attention should be paid to the timing of fertilization, as only midday fertilization can guarantee a very efficient nutrient absorption of cucumbers. Attention should be paid to the frequency of watering, as cucumbers require a very high amount of water.

Pay attention to cucumber planting skills, but also should pay attention to the prevention of pests and diseases, but also pay attention to the renovation of the soil, and fertilization, but also pay attention to temperature control.

The first thing to pay attention to is to control the water content of cucumbers, cucumbers are particularly fond of water.

Secondly, it is necessary to increase the number of watering times in the flowering and fruiting period, and also pay attention to fertilization.

Finally, some herringbone racks should be set up to make cucumbers grow better.

Be sure to plant in the sunny and fertile land, and then water the land every day to make the land particularly moist, and apply fertilizer every two days, so that the land can be more nutritious, but be sure to pull out the surrounding weeds, so as not to absorb the nutrients of the land, and wait for the cucumber seedlings to grow out of the daily observation, if you find harmful insects or germs must be sprayed with pesticides in time.

When planting cucumbers, you must choose the right temperature, and then when planting, you must choose fertile soil with good air permeability, and during planting, you should also water more water on cucumbers, apply more household fertilizer and nitrogen fertilizer to it, and then you should also spray pesticides to prevent pests and diseases in advance, so that the yield of cucumbers planted is particularly high.

Cucumbers, whether eaten raw or cooked, taste very good. In fact, if you are interested in growing cucumbers, you can also try them at home, so what are the planting steps and precautions for cucumbers?

First, planting time.

The planting time of cucumber is generally around 3-4 months of each year, when the weather is already warmer, higher than 5 at night, and can reach 18 during the day, which is suitable for the growth and development of seedlings. Different regions also need to be adjusted according to the local climate, which can be earlier or later. In addition, planting can also be carried out in autumn, if it is not planted too late, the frost will affect its quality and even lead to production restrictions.

Second, soak seeds to promote germination.

Before planting, the seeds should be primed. Prepare 50 meters of boiling water in advance, put the seeds in and soak them for a few minutes, which has the effect of sterilization and disinfection. Then change to 30 degrees of warm water and soak for 3-4 hours.

After removing it, put it in a damp cloth, keep the temperature at around 20, and sprinkle water often to keep it moist, so that after about two days, you can see the seeds white.

Third, temperature requirements.

Under normal conditions, when the cucumber is harvested, the ambient temperature during the day should be adjusted between 25 and 28 degrees. If it exceeds 30 degrees, you have to increase the exhaust airflow. At night, the temperature should be adjusted between 16 and 20 degrees.

The temperature setting can make the first half of the night higher than the second half of the night. Experiments have shown that cucumber leaves have only 1 4 nutrients during the day and 3 4 nutrients at night, so in the first half of the night, we can reduce the temperature moderately. This facilitates the transport of nutrients in the leaves.

Fourth, precautions.

Fertilizers contain a large number of parasites that are harmful to the human body, and can be replaced with well-rotted chicken manure, which is basically better for growing vegetables today. 2 ammonium hydrogen phosphate or ammonia can be added to the chicken manure water, stirred, and covered with plastic film, so that it can be piled up for 7 10 days under absolutely closed conditions, which can achieve the purpose of purification and pesticide. Cucumbers and most of the melons and vegetables, generally only ammonium nitrogen fertilizer (ammonia, ammonium phosphate, ammonium sulfate, urea), can not use ammonium nitrate and ammonium chloride, fertilizer at the time to pay special attention not to abuse at will, in order to prevent fertilizer poisoning.

Before planting cucumbers, the cucumber seeds should be soaked in warm water. Then the cucumber seeds and pesticides are stirred together, and a layer of plastic film should be laid after planting, and the soil should be kept moist, and the temperature should be kept at about 25 degrees.

When planting, we must choose the soil is relatively fertile and broad, and we must use farmhouse fertilizer when fertilizing, do not use the fertilizer bought outside, and often water the plants, but also to prevent the occurrence of pests and diseases, if there is a situation of small insects, then we must spray insecticides in time.

First of all, we should choose high-quality varieties, then timely watering and fertilization, keep the light sufficient, spray pesticides regularly, remove insect pests in time, do a good job of drainage and ventilation, and be sure to control the temperature, the temperature should be controlled at about 23.

Precautions include pest control, blight control, and brown spot disease. Attention should be paid to the selection of varieties, pest control and water and fertilizer management. In addition to paying attention to water and fertilizer, it is also necessary to control the planting density. Strengthen fertilizer and water management, and prevent and control pests and diseases in a timely manner.

1. Water and temperature: watering when planting, to prevent soil stratification, affect the growth of seedlings, 10 15 days after planting the second water, to water enough, can be flushed with water with its own nutrients of biological bacteria flushing fertilizer, so that cucumbers slow seedlings fast, good growth, to prevent rotten roots and dead trees; During the seedling stage, the temperature is about 25 32 during the day and about 15 17 at night.

2. Reasonable top dressing: before and after the flower bud stage, the foliar spray contains organic acid of boron calcium foliar fertilizer, organic acids can make boron calcium complex together, forming a whole, boron and calcium supplementation is better, promote the absorption and transformation of other nutrients, improve photosynthesis, promote the completion of flower buds, and improve fruit setting rate.

During the fruiting period, the center of gravity of growth shifts from rhizomes and leaves to fruits, and it is necessary to increase nutrition in time to ensure the growth of cucumbers, and supplement organic and inorganic nutrients at the same time.
