Planting techniques of Cucumber in soil

Cucumbers, I believe that many people grow at home, especially in the countryside almost have vegetable families will grow cucumbers, because cucumbers and delicious and nutritious, and is a very easy to grow vegetables. So how to grow cucumbers? Let's go and have a look with the editor.

Planting techniques of Cucumber in soil

1. Variety selection

The varieties with high yield, strong disease resistance and good marketability should be selected, which are suitable for spring open field cultivation, such as Jinchun 4, Zhongnongda 11, Zhongnongda 12, Bomei 4, Derit 902, Zhongnong 12, etc. the varieties suitable for autumn open field cultivation are Jinyou 3, Jinyan 2, Tangshan autumn melon and so on.

2. Raising seedlings

Seedling age is about 35 days, strong seedling standard: cotyledons are intact, there are 3-5 true leaves, internodes are short, the angle between petiole and main vine is 45 degrees, leaf color is dark green, leaves are thick, stems are stout, roots are developed, and there are no diseases and insect pests.

3. Fertilizing to make beds

Soil preparation, fertilization mature organic fertilizer 5 cubic meters, calcium superphosphate 25-30 kg or diammonium phosphate 10-15 kg. Plough the border before planting, 1.2 meters wide, more than 15 centimeters high, and covered with plastic film.

4. Colonization

Determination of planting period: on the premise of ensuring that it is not frozen after planting, Chengde area is generally planted at the end of April and the beginning of May. Temperature index requirements: the lowest night temperature is higher than 5 ℃, and the soil temperature at 0-10 cm is higher than 12 ℃. Cucumbers in autumn open field are direct seeded.

Planting density: 4000000 trees / mu, big and small rows, small row spacing 40 cm, large row spacing 80 cm, plant spacing 25-30 cm, planting by dark water method.

Field Management of Cucumber

The moisture content of cucumber should be controlled at seedling stage. The largest amount of water is needed in the flowering and fruiting period, which is usually watered once a day in sunny days and irrigated once in 3-5 days of drought. It is necessary to do a good job in flood prevention on rainy days.

Soil fertilization: cucumber responded well to base fertilizer. During soil preparation, deep tillage increased the application of rotten organic fertilizer, applying 2000 kg-3000 kg per mu, 50 kg wool fertilizer and 30 kg superphosphate as base fertilizer. When the plant has 2-3 true leaves, it begins to fertilize. Cucumber root has weak absorptivity and is sensitive to high concentration fertilizer. Topdressing is based on the principle of "frequent and thin application", once every 6-8 days, and urea 5kg-6kg per mu.

Pest control: cucumber downy mildew, powdery mildew, etc.; insect pests include aphids, whitefly, Liriomyza huidobrensis and so on. It is necessary to strengthen cultivation and fertilizer and water management, increase the application of phosphorus and potassium fertilizer, improve plant disease resistance, and pay attention to greenhouse ventilation, light transmission and humidity reduction, so as to create conditions that are not conducive to the occurrence of diseases and insect pests. In the early stage of the occurrence of diseases and insect pests, effective chemical control measures should be taken to control the diseases and insect pests in order to prolong the melon harvest period and achieve the purpose of increasing production and income.

Planting time of Spring Cucumber

Spring cucumber refers to the cucumber that is raised in winter and harvested in spring. Let's take a look at the sowing time and planting time of spring cucumber:

1. The sowing time of spring cucumber: the sowing time of spring cucumber is determined according to the planting date, the suitable calendar seedling age is 40-50 days, and the physiological seedling age is four leaves. If the seedling age is calculated according to the calendar, the seeds will be sown 40-50 days before planting. The age of physiological seedlings is related to the method of raising seedlings. It takes 50-55 days to raise seedlings in sunny beds or solar greenhouse, 45-50 days in heating greenhouse and 45 days in electric hotline greenhouse. Therefore, the sowing time is also different with different seedling raising methods. Practice has proved that rapid seedling raising not only saves time, but also emerges quickly and thrives, and the early yield is high. Where there are conditions, try to use rapid seedling breeding.

2. The planting time of spring cucumber: the planting time of spring yellow claw is after the local late frost, and the ten-day average temperature 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 in cloudy or windy days. The planting density is mainly determined by the characteristics of the variety.

Birth cycle

1. Germination period: from sowing to the appearance of the first true leaf, generally 5-7 days, the growth at this stage is small, the speed is slow, and high temperature and humidity and sufficient light are needed to promote early emergence, neat emergence and prevent overgrowth.

2. Seedling stage: it usually takes about 30 days from the first true leaf to the 4th-5th true leaf. At this stage, flower bud differentiation begins, but the growth center is still root, stem, leaf and other vegetative organs. The management goal is to promote the combination of control and cultivate strong seedlings.

3. Early flowering stage (spreading stage): it takes about 20 days to expand from the 4th to 5th true leaves to the first female melon. At this time, vegetative growth and reproductive growth are carried out at the same time, and the growth center is gradually transformed from vegetative growth to reproductive growth.

4. Melon setting period: from the first female to pulling seedlings, the duration varies with different cultivation methods. At this stage, the growth rate of plants slowed down, focusing on the development of fruit and flower buds. Adequate water and fertilizer should be provided to promote melon bearing and prevent premature senility.

The above is the planting method of ground cucumber summarized by the editor. I hope it can help you. As we all know, cucumber is a special nutritious vegetable, and it can be eaten raw, whether fried or eaten raw. For female friends, cucumbers can help you whiten and lose weight.
