What varieties of cucumbers are suitable for planting from July to August

Cucumber belongs to one of the Cucurbitaceae plants, the light saturation point is lux, the temperature range suitable for growth is 18 32 degrees, at the temperature of about 24 degrees, is the most suitable temperature, cucumber on the light requirements are relatively relaxed, as long as the temperature is suitable, there is enough scattered light, can also grow well, therefore, cucumber can be cultivated in the winter in the solar greenhouse protected area, in the four seasons of the year. In order to grasp the demand of the market, most cucumbers cultivated in the open field will choose to raise seedlings from March 10 to 20 in spring, and after May 20 to June 20 in summer.

The best time to grow cucumbers is in spring, when temperatures are above 18. So, in the south, it can be planted around March, while in the north, it can be planted around April. In addition, it can be planted from late May to mid-June in the summer and July to August in the fall.

Cucumbers grown in the open field can generally be sown in the spring. Spring is a suitable period for sowing cucumbers, generally can be carried out in early spring, when the temperature gradually stabilizes, the open-air environment has thawed and thawed ice, in order to avoid the spring cold, you can cover the soil with a layer of plastic film. In addition, it can also be sown in late summer and early autumn, generally about 70 days before the frost comes, prepare suitable seeds before sowing, and sow seeds after soaking and germination.

When are cucumbers planted? In the south, it can be cultivated all year round. In our northeast, it is necessary to plant in the middle of the solar calendar, and if you plant early, you will freeze to death, and if you plant late, you will not have a good harvest.

The autumn cucumber variety is mainly Zhongnong No. 8, which has high yield, more than 10,000 catties per mu and good commerciality. In addition, Jinqing No. 4 and Jinyou No. 4 are also suitable for autumn cucumber cultivation.

Autumn cucumbers should be planted in sandy loam fields with convenient fertilizer and water retention, drainage and irrigation. Before sowing, more than 1,500 kg of farm soil fertilizer is applied per mu, and ploughed into the soil. Then use 50 kg of 45% tri-compound fertilizer to cultivate, and the seeds can not touch the compound fertilizer.

The furrow is wide and meter, planted in two rows, and the plant spacing is about 30 cm. Sow two seeds per reclamation and cover the soil by centimeters.

After the seedlings emerge, 150 ml of 40% chlorpyrifos can be sprayed on the furrow surface to prevent the damage of ground tigers. At the 2 4-leaf stage of the seedlings, Li Sheng sprayed four plants every other plant with a thousandth of ethephon solution to promote the increase in the number of female flowers. 4 leaf stage seedlings, one for each plant, and set up a frame in time.

After the first batch of cucumbers are harvested, urea is applied at 30 kg per mu. In case of drought, irrigation should be carried out in time, irrigation should be carried out in the second half of the night, and irrigation should not be carried out at high temperature at noon to prevent dead seedlings.

Pest control should be carried out before cucumber harvesting. 58% methalenese-zinc, 50% methalene-copper, and 10% guaron can be used for diseases. Pests can be controlled with pollution-free pesticides such as 10% imidacloprid and 40% chlorpyrifos 800 times. No pesticides can be used after cucumbers are harvested.

Cucumber is a very common vegetable in our life, with a sweet and cool taste, and has the effect of clearing heat and diuretic, especially one of the vegetables in summer. According to research, cucumber sowing can be divided into spring and autumn, spring sowing is generally eaten in summer, so which season is more suitable for planting cucumbers in autumn? Can you plant cucumbers in August?

Let's follow this article to find out.

Can you grow cucumbers in August?

According to the past practice, the sowing time is between 1-3 months in spring and 6-8 months in summer and autumn, so cucumbers can be planted in August. It is especially recommended that in the colder north, the sowing time of cucumbers can be arranged in early August, and then the time of the second crop can be arranged around the Spring Festival, which can effectively avoid the coldest period of winter and make the survival rate of cucumbers higher.

Cucumber's survival requirements

1. Temperature: cucumber is not cold-tolerant vegetables, prefer to grow in a warm place, the temperature of the shelter to survive is about 10-32 degrees, too low or too high will affect the development of cucumbers, according to the survey above 35 degrees of temperature cucumber photosynthesis will be bad, so it is not that the higher the temperature, the better.

2. Moisture: The high yield of cucumber is inseparable from the demand for water, the seedling period does not need much water, the moisture of the soil is suitable for about 60-70%, but when it comes to flowering and fruiting, the demand for water rises, and 80-90% soil moisture is needed, in general, the suitable soil moisture of cucumber is about 60-90%. If the humidity of the air is too high, it is easy to make cucumbers sick, and then cause low yield.

3. Survival soil: Although cucumbers like moist places, they do not tolerate too much moisture soil. Therefore, it is suitable to choose a soil with a particularly rich organic matter, and then the pH index is the most suitable between.

4. Light: cucumbers can be divided into light requirements according to varieties, South China type is very sensitive to short daylight, North China type is less strict in terms of sunshine, and the general sunshine duration is about 8-11 hours.

How to grow cucumbers

1. After selecting good cucumber seeds, sow them in flower pots or other land, and ensure that the soil for survival is fertile.

2. Cucumber seeds will appear vines after planting for a period of time, and at this time, it is necessary to build a vine trellis for cucumbers.

3. After the vine trellis is erected, you need to water the cucumber properly and ensure the fertilizer of the soil, and then you can wait for the normal growth of the cucumber.

The above is some of the analytical insights put forward in this article on whether cucumbers can be planted in August, and the planting conditions and methods of cucumbers are summarized, hoping to help you in the future cucumber planting. The planting method is very simple, basically Hongkut can be planted from April to August every year, if you use the greenhouse planting month time will be more flexible, come and try it.

The sowing of cucumbers is divided into spring and autumn, and cucumbers in spring are generally eaten in summer, in addition, cucumbers are also planted in autumn. So, can you grow cucumbers in August? Can you grow cucumbers in August?

Can you grow cucumbers in August?

Cucumbers should be sown in early spring 1-3 months, and planted in summer and autumn 6-8 months. The Northeast is relatively cold, so it is recommended that autumn cucumbers be planted early, preferably in early August, and then planted before the Spring Festival for the second crop or after the Spring Festival, so as to avoid the coldest period.

Cucumber planting time.

1. The sowing time of spring cucumber: the sowing date of spring cucumber is determined according to the planting period, the suitable calendar seedling age at the time of planting is 40-50 days, and the physiological seedling age is four leaves and one heart. If the seedling age is calculated according to the calendar seedling age, sowing is carried out 40 to 50 days before planting.

The length of physiological seedling age is related to the seedling method, and the seedling is raised in a sunny furrow or solar greenhouse for 50 to 55 days; seedlings were raised in a heated greenhouse for 45-50 days; Raise seedlings in a greenhouse for 45 days. Therefore, the seedling raising method is different, and the sowing time is also different. Practice has proved that rapid seedling raising not only saves time, but also emerges quickly and strongly, and the early yield is high.

Where conditions permit, try to use rapid seedling rearing.

2. The planting time of spring cucumber: the planting time of spring yellow claw is after the local late frost, and the average temperature in October is more than 18t. Beijing, Tianjin, and Shijiazhuang are generally planted after late April.

In order to slow down the seedlings quickly, choose sunny days to plant seedlings, do not plant on cloudy and windy days. The density of colonization is mainly determined by the characteristics of the variety.

The growth habit of cucumbers.

1. Temperature: Cucumbers like warmth and are not tolerant to cold. The fertility temperature is 10 32.

Generally 25 32 during the day, with 15 18 at night to grow the best;The most suitable ground temperature is 20 25, and the lowest is about 15. The optimal temperature difference between day and night is 10 15. Cucumber high temperature 35 poor photosynthesis, 45 high temperature obstacles, low temperature -2 0 freeze to death, if low temperature refining seedlings can withstand 3 low temperature.

2. Light: South China varieties are more sensitive to short days, while North China varieties are not strict about the length of sunshine, and have become sunshine neutral plants, with a light saturation point of 10,000 lux and a light compensation point of 1500 lux, and most varieties grow well under the condition of 8 11 hours of short daylight.

3. Moisture: cucumber has a high yield and a large water requirement. The suitable soil moisture is 60 90%, the water at the seedling stage should not be too much, the soil moisture is 60 70%, and sufficient water must be supplied at the fruiting stage, and the soil moisture is 80 90%.

The suitable air relative humidity of cucumber is 60 90%, and excessive air relative humidity is easy to get sick, resulting in reduced yield.

4. Soil: cucumbers like moisture but not waterlogging, fertilizer but not fertilizer, and it is advisable to choose fertile soil rich in organic matter. Generally prefer between the soils, but take the pH as the best.

Cucumbers are generally planted in spring and summer, in most cases cucumbers are most suitable for planting in January and March each year, and can be planted in June and August at the latest. There is a gap between the time of greenhouse planting and the time of planting cucumbers in the open air, and the time for planting cucumbers in greenhouses is about November in winter, and the seeds of cucumbers can be maintained in the open air after they grow into young seedlings.

Cucumbers are generally planted in spring and summer, in most cases cucumbers are most suitable for planting in January and March each year, and can be planted in June and August at the latest.

The climate in the south and the north will be different, so the suitable time for planting cucumbers is also different, generally the south will plant cucumbers in December in the spring, and the north will generally plant cucumbers in mid-February.

Cucumbers can be planted in greenhouses, there is a gap between the time of greenhouse planting and the time of planting cucumbers in the open air, the time of planting cucumbers in greenhouses is about November in winter, and the seeds of cucumbers can be maintained in the open air after they grow into young seedlings.

Cucumber origin and planting month.

Cucumber is a common plant, widely cultivated in the world, mainly concentrated in temperate and tropical regions, generally in China's main production areas in Hebei, Shandong, Shanxi, Shaanxi, Liaoning, Yunqing, Beijing, Tianjin and Jiangxi.

Shanxi cucumber. Shanxi cucumber will generally be planted in January, generally will ripen in the month, Shanxi cucumber is relatively slender, the peel color is very fresh, the fruit point is relatively dense, the taste is cool and delicious.

Hebei cucumber. Hebei cucumbers are planted around February and usually ripen at the end of April, Hebei cucumbers have good disease resistance, the fruit is relatively crisp, and there is a refreshing feeling to taste.

Cucumber varieties and planting months.

Cucumbers will be divided into different varieties according to different origins, generally there will be water cucumber, dry cucumber, Sikkin cucumber, Chinese Banna cucumber, Zhaotong cucumber, Yangzhou milk cucumber and European and American manuscript type.

Sikkim cucumbers. Sikkim cucumbers are generally planted in January and March, and will ripen in the month, Sikkim cucumbers grow thicker, the shape is cylindrical, the color of the skin is lighter, and the skin will be a little thicker.

Dry cucumbers. Cucumbers are usually planted in June and ripen in the month, and the fruits are short and thick, with more black thorns on the skin, and the skin is thick and hard.

Cucumber planting season:

In spring, seedlings are sown from late February to early March, and planted in early to late April.

Autumn is generally broadcast from late July to early August, and harvested from early September to late October.

Cucumber cultivation techniques

Land preparation

5 cubic meters of organic fertilizer for land preparation and fertilization, 25 to 30 kg of superphosphate or 10 to 15 kg of diammonium phosphate (5 kg of superphosphate per cubic meter, 2 to 3 kg of diammonium phosphate per cubic meter). Before planting, plough the furrow, the width of the furrow is more than 15 cm, and it is covered with mulch.

Colonization

Determination of planting period: planting as soon as possible on the premise of ensuring that there is no freezing after planting, and planting in Chengde area is generally in late April and early May. Temperature index requirements:

The minimum night temperature is above 5 and the soil temperature is above 12 at 0 to 10 cm. The cucumber in the autumn dew field adopts the method of live broadcasting.

Planting density: 4000 to 4500 acres, planting in large and small rows, small row spacing 40 cm, large row spacing 80 cm, plant spacing 25 to 30 cm, planting with dark water method.

Management

Sockets. After planting, the shelf should be planted as soon as possible, and the seedling should be pumped by wind, and the shelf can be a flower stand or a herringbone frame, about 8 to 10 cm away from the root.

Tie vines. The "8" method is used to tie vines to prevent abrasion of stems and vines and sagging stems. Every 2 to 3 knots are tied, should be carried out in the afternoon, the stem vine is easy to break in the morning, the tightness of the vine should be suppressed and the weak should be strengthened, and the growth of the plant should be tied a little tighter, and the height of the growth point is consistent.

Pruning and pinching. For the main vine, all the side branches should be removed, and one or two leaves should be left after the side vine is fruitful, and all the tendrils should be removed. When the stem exceeds the head of the shelf, it is necessary to pinch the tip in time to promote the growth of the lower melon, and the method of twisting the tip can also be used to inhibit the growth of the upper part.

Fertilizer and water management. Timely watering and cultivating, the amount and frequency of water depends on the weather and growing period. Slow seedling water is watered 5 to 7 days after planting; water control, cultivating, and squatting seedlings before sitting on melons; When the root melon is 10 to 12 cm long, water the melon; Watering during the fruiting period is done every 5 to 7 days.

The principle of top dressing is that the front is light and heavy, a small amount of many times, urging melon fertilizer to be applied after the root melon sits, and the melon fertilizer is carried out after the root melon is harvested. Promote the use of organic fertilizer topdressing.
