Detailed explanation of cucumber cultivation techniques

Recently, someone asked when to plant cucumbers. How to plant it? I don't think this friend is from the countryside, because people who often work in agriculture don't know the planting time of cucumbers. Cucumbers are generally divided into spring cucumbers and summer and autumn cucumbers. Spring cucumbers are sown from January to March, while summer and autumn cucumbers are sown between June and August, so how to plant cucumbers? Let's explain it for you.

Cucumber should be sterilized before sowing, so as to avoid the occurrence of many diseases and insect pests. Generally, as long as it is scalded in warm water of 50 to 55 degrees, it is necessary to keep stirring to prevent the seeds from being scalded. After that, soak in 30 degrees warm water for about 4 to 6 hours, then wash it and remove it and drain it to wait for germination. Cucumber seeds can germinate in 20 hours as long as they are in a warm and moisturizing place.

Cucumbers planted in early spring need to be planted. Seedling cups or seedbeds can be used to raise seedlings, while cucumber seedlings can be planted at the age of 15 to 20 days. At this time, it is best to choose the evening, because the temperature at this time is the least likely to cause damage to cucumber seedlings. When planting, we need to pay attention to protect the roots of cucumber seedlings, and before the seedlings should be drenched in water, according to the order of seedlings, must be planted with soil to prevent root damage.

How to grow cucumbers with good taste

Balance the right amount of fertilizer

One is extra-root topdressing. Rare earth micro-fertilizer was sprayed once at seedling stage, early flowering stage and young melon stage, and was sprayed with 0.5 kg urea and 150 kg water per mu at full flowering stage and full fruit stage. The second is to fertilize the roots. The application of nitrogen fertilizer should be controlled at seedling stage to avoid overgrowth of plants. At the peak stage of flowering and fruiting, the ratio of nitrogen, phosphorus and potassium uptake by cucumber is basically 5 ∶ 2 ∶ 6. At this stage, the supply of nitrogen and potassium fertilizer should be strengthened.

Avoid low or high temperatures

First, when the air temperature or ground temperature is lower than 13 ℃, the cell permeability decreases, the absorption of nutrients and water is inhibited, and cucumber is prone to bitterness; second, the greenhouse temperature is higher than 30 ℃ and lasts for too long will also lead to cucumber bitterness. Therefore, it is necessary to enhance the temperature and heat preservation performance of the protective facilities as far as possible, adjust the temperature, and avoid the temperature limit formed by bitterness.

Watering should be reasonable and timely

First, in the case of high temperature and less soil moisture, the plant has physiological drought, which is easy to produce bitter melon. At this time, it is necessary to supply water to cucumbers in time to maintain the swelling and pressure of plant tissue and the stability of plant temperature. Second, watering should be done a small number of times, the water temperature should not be too low, to prevent water deficit in the plant leading to the formation of cucumber picrin. In addition, pay special attention to squatting seedlings after planting should not be excessive, otherwise the root melon is easy to suffer.

The density should not be too high.

The planting is too dense and the light is poor, which will aggravate the bitterness of cucumber. Cucumber cultivation in protected field should adopt the method of close planting in the early stage and sparse planting in the later stage, that is, the common plant spacing is 2630 cm and the row spacing is 60 cm. If the plant spacing is 15 cm, the "single plant" on the same ridge is not on the shelf, and when it grows to 12 true leaves, it can quickly bear melon, and the main vine melon can be pulled out after harvest, and the "compound plant" will be put on the shelf. When the plant grows to 1.2 meters high, it will be accelerated to bear melon, and the main vine melon will also be pulled out after harvest. In this way, the early yield can be nearly doubled, and the occurrence of bitter melon will be reduced at the same time.

Prevent damage to the root

Root damage will aggravate the bitterness of cucumbers. In production, sand table sowing should be used to reduce root injury, plastic nutrition bowl or paper pocket should be used to separate seedlings, ridge plastic film mulching should be used as far as possible, and shoveling should be slightly deeper in the early stage and shallower in the later stage.

How to plant cucumber for high yield and good quality

Big belly melon. The cause of formation is to take preventive measures:

① cucumber female flower fertilization is not complete, only produce seeds at the apex of the melon, so that nutrients accumulate to the apex, resulting in the apical pulp tissue is particularly hypertrophic, showing a big belly melon head. Create good conditions of flowering and pollination for control.

② plants are deficient in potassium and oversupplied with nitrogen fertilizer, which will produce melons. Control measures: apply potassium nitrate, plant ash, etc., or spray plant leaves with 0.3% potassium dihydrogen phosphate solution.

③ cucumber is short of water in the early growth stage, but a large amount of water supply in the later stage will produce big belly melon. This is because water has a strong effect on the elongation or hypertrophy of cells. when water is scarce, cells grow slowly, while when there is a large amount of water supply, cells develop rapidly. Prevention and control measures: balanced water supply throughout the growing period, keep the soil wet, and avoid excessive drought, water shortage or flood irrigation.

Curved melon. The cause of formation is to take preventive measures:

① cucumber was not fertilized completely, only the egg cells on one side of the ovary were fertilized, resulting in the unbalanced development of the whole fruit and forming a curved melon.

During the growth period of ② cucumber, curved melons were produced due to the influence of high temperature, high humidity and bad climate. Prevention and treatment technology: take a toothpick, stick it on the cucumber vine that produces curved melon strips, then pour water again, the melon strips can be straightened the next day, and then pull out the fine toothpick, the cucumber can still grow normally.

During the growth of ③ cucumber, the melon strips were blocked by external objects and could not stretch normally, resulting in abnormal bending. Control measures: after the cucumber sits on the melon, remove the external objects that hinder the growth and development of the cucumber, which can make the cucumber elongate normally.

The above is the planting method of cucumbers, of course, summer and autumn cucumbers do not need to be so complicated, only need to sterilize the seeds to sow, so summer and autumn cucumbers are the cheapest on the market. Now does this friend know when to grow cucumbers?
