Cucumber seed retention is generally when the cucumber is old, you can pick it off and keep it, but it is not recommended to keep your own seeds. Because of the survival rate, the rate of raw melons is not high.
Cucumber seeding: The precocious offspring of cucumber plants in different parts of the plant are different.
The precociousness of the second and third melons is not as good as that of the first melon, but the temperature is low when the first melon is born, and the pollination is often not good, and the seeds are small and few, so artificial pollination is necessary to improve the quantity and quality of the seeds. The seeds of the second and third melons are both full and abundant, therefore, the first melon should be left for seeding with early maturity as the selection goal, and the second or third melon can be left for general field seeding.
Cucumber is an annual creeping or climbing herb of the Cucurbitaceae family. The stems and branches are elongated, furrowed, and covered with white rough bristles. The tendrils are thin.
petioles slightly rough, with rough bristles; Leaves broadly ovate-heart-shaped, membranous, lobes triangular, toothed. Monoecious. Male flowers:
constant flowers are clustered in leaf axils; peduncles slender, slightly pubescent; The corolla is yellowish-white, and the corolla lobes are oblong-lanceolate. Female flowers: solitary or sparsely clustered; peduncle stout, pubescent; The ovary is rough.
The fruit is oblong or cylindrical, yellow-green when ripe, and has a rough surface. Seeds are small, narrowly ovate, white, without edges, and nearly acute at both ends. Flowering and fruiting period in summer.
It is widely cultivated in various parts of China, and in many areas there are greenhouses or plastic greenhouses; It is now widely cultivated in temperate and tropical regions. Cucumber is one of the main summer vegetables in China. The stems and vines are medicinal, anti-inflammatory, expectorant, and antispasmodic.
Cucumber rinds are rich in nutrients and should be kept for raw consumption. However, in order to prevent the harm of pesticide residues to the human body, cucumbers should be soaked in salt water for 15 to 20 minutes before washing raw food. When soaking cucumbers in salt water, do not pinch the head to remove the roots, and keep the cucumber intact to avoid the loss of nutrients from the cut surface during the soaking process.
In addition, cold salad should be cooked and eaten freshly, and should not be left for a long time after cooking, which will also promote the loss of vitamins.

Generally, when it is yellow, it matures when it is old.
Experienced vegetable farmers keep the seeds, generally until the cucumber seedlings are removed, and when the vegetables are replanted, the cucumber seeds and cucumber seedlings are removed together.

Cucumbers can certainly be planted in autumn.
Cucumber cultivation techniques
5 cubic meters of organic fertilizer, 25 to 30 kg of superphosphate or 10 to 15 kg of diammonium phosphate (5-5 kg per cubic meter of superphosphate, 2-3 per cubic meter of diammonium phosphate). Before planting, plough the furrow, the width of the furrow is more than 15 cm, and it is covered with mulch.
Determination of the 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.
Manage shelfs. 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 growth 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.

Cucumbers can be planted in the fall. This is what we usually call autumn cucumbers. But in the Northeast, it is too late to plant autumn cucumbers in the open field this season, and there are thermal insulation sheds.
-
First of all, cucumbers can be planted in autumn, but cucumbers planted in autumn must be planted in greenhouses, because even if they germinate in autumn, they will not grow or even die when the temperature is cool in winter.
The normal sowing season for cucumbers should be around February to April in the spring.
-
Cucumbers can be planted in autumn, which is called cucumbers after autumn, not only yellow claws, but also beans, these are vegetables that can be planted in autumn, and we generally plant them.
-
The beginning of autumn is autumn, and cucumbers can be planted, and autumn cucumbers are planted. Autumn cucumber, also known as dry cucumber, is a variety of cucumber with a rich taste and rich nutrition.
-
Hello! It depends on the local climatic conditions. Cucumbers are not tolerant to cold, so they cannot be grown in places where it snows. Like the western and southern parts of Yunnan, where the temperature is high throughout the year and there is no snow in winter, it is suitable for planting in autumn and harvesting around the Spring Festival.

Autumn cucumbers are best sown in July or August, and are usually harvested at the end of October. Autumn cucumber planting should pay attention to the selection of good varieties for planting, and control the temperature, there needs to be a certain temperature difference between day and night, which is conducive to inhibiting plant growth and preventing flower and fruit dropping.
Precautions for autumn cucumber planting:
1. It is necessary to reasonably match fertilizer, and in the fertilization process, nitrogen, phosphorus, potassium fertilizer and microbial fertilizer, multi-element mineral fertilizer and organic fertilizer should be used reasonably, so as to promote the growth of autumn cucumber roots, supplement nutrients, prevent premature aging of cucumber roots and leaves, and reduce the production of deformed melons.
2. Reasonable irrigation, the amount of watering demand in each period is different, and it is necessary to distinguish the demand of each period, as well as timely irrigation and watering.
3. It is also necessary to pay attention to the fertilization in the later stage, due to the lack of fertilizer in the later stage of autumn cucumbers, which will lead to premature aging, shortening the effective harvest period, decreasing cucumber yields, and increasing deformed melons such as curved melons, in order to ensure that the nutrients in the later stage are sufficient, it is generally necessary to top dressing 8 10 times after planting, and it should be used in combination with organic fertilizer.

Depending on the region, autumn cucumbers are planted early and late.
Starting from the first to mid-July, it can last until early August, however, after mid-to-late August, it is not recommended to plant autumn cucumbers, especially in the northern region, considering the growth period of cucumbers, if sowing is too late, and then wait until the frost, the cucumbers have not yet borne fruit, and it is basically difficult to bear fruit.
The planting of autumn cucumbers just makes up for the gap period. For friends who have a vegetable garden at home, plant autumn cucumbers at this time, and wait until September to pick them in the city.
For vegetable farmers who plant autumn cucumbers in a large area, after the autumn cucumbers mature and go on the market in September and October, they are staggered vegetables, which are relatively high and relatively profitable.
-
Autumn cucumbers are planted in early August and grow for more than 80 days.
Autumn cucumbers are generally planted in early August, and in some parts of the south, they are also planted in mid-July. Autumn cucumbers are planted after August, so that the temperature gradually decreases, and the seedlings cultivated at this time can better avoid the high temperature in summer, which improves the survival rate of cultivated seedlings.
The growth period of autumn cucumbers is actually very short, and it can be harvested in more than 80 days. Therefore, it is important to manage the cultivation of cucumbers in less than three months.

1, autumn open field sowing cucumber is generally in North China and East China, 6 to 7 months is usually the sowing period, 8 to 9 months for the harvest period, autumn sowing cucumber plays an important role in the supply and demand of vegetables after the autumn off-season, 7-8 months is the rainy season and high temperature festival, it is the early growth of autumn cucumbers, to choose those who are relatively strong, the seedling stage to be heat-resistant and the later stage must be cold and drought resistance, disease resistance and other varieties that are not sensitive to long sunshine.
2. Select excellent varieties with strong plant growth potential, high temperature resistance at seedling stage, strong disease resistance, low temperature tolerance during the bulk transportation period after growth, and slightly larger fruit shape. Such as Zhongnong No. 2, Jinyou No. 4, Jinlu No. 5, Jimei No. 4, Jinyou 40, Jinyan No. 4, Jinza No. 4, Jinza No. 3, Ji Cucumber No. 1, No. 2, Xiaqing No. 2, Tangshan autumn melon and other late-maturing varieties in Chong Daliang. Early-maturing varieties are often satisfied too early due to accumulated temperature, and a large number of melons are produced before the stems and leaves have time to grow in sufficient amount, resulting in melon seedlings, uneven plants, and serious deformity of melon strips.

The planting time of autumn cucumbers in the open air is generally in early August every summer, because the temperature at this time is low, and some pests and diseases can be avoided when planting. In addition, the temperature in August can prevent cucumbers from growing and falling flowers and fruits, and in the southern regions, its planting will be delayed due to the different climates.
Open-air autumn cucumbers are suitable for planting time.
The planting time of autumn cucumbers in the open air is generally in early August every summer, because the temperature at this time is low, and some pests and diseases can be avoided when planting. In addition, the temperature in August can also prevent the occurrence of cucumber growth and flower and fruit dropping, and the planting time of spring will be delayed due to the different climates in the southern region.
Methods and points of planting autumn cucumbers in the open air.
1. When planting cucumbers in the open air, the seeds need to be treated first, and the seeds should be soaked in warm water at 25 degrees for about 6 hours, wash off the dirty substances on the surface, and then wrap the seeds with a damp cloth and put them in the environment of 25 for germination treatment, and they can be sown after one day.
2. Dig a hole with a depth of about 2 cm in the soil, then put the seeds of autumn cucumbers in the open air, cover the soil and water it to a moist state, and then put it in a place with astigmatism and ventilation, and wait for about 3 days to take root and sprout.
Points to note in the management of autumn cucumbers in the open air.
Open-air autumn cucumber likes to grow in a warm environment, its normal growth temperature is between 20 and 32 degrees, if the temperature is below 15 degrees, it will be frostbitten, and when the temperature is higher than 35 degrees, its leaves are easy to be burned.

What is the definition of time?
1. Planting time.
Generally speaking, it is mainly sown in March and April in spring, and harvested in June and July, and can also be planted in September and October in autumn, and harvested in April and May in the spring of the following year, but it is mainly sown in spring. >>>More
A: The dinosaurs died out between 7,000 and 100 million years ago.
The dinosaurs became extinct 66 million years ago, and the main reason for their extinction was probably due to planets hitting the Earth, followed by global volcanic eruptions. Now we see dinosaurs generally from books or some movies and television, TV series we can also know what dinosaurs look like, these are scientists after years of research, and archaeologists have also excavated a lot of dinosaur fossils. >>>More
