Which cucumbers are suitable for planting in summer and autumn? (with planting technology)

Cucumber is one of the most common vegetables in China, with various varieties and simple planting techniques, so many people plant it, but due to regional and climatic problems, it is not possible to grow cucumbers in all seasons. What are the suitable cucumbers for summer and autumn?

1. Lu Cucumber No.2

Cultivated by vegetable Research Institute of Shandong Academy of Agricultural Sciences. The growth potential of the plant is strong, mainly with the main vine, and the branching is weak. The leaves are green and palmately pentagonal. Melon strips are long stick-shaped, with green peel, white prickle, medium density, thin and crisp skin and good quality. This variety is relatively heat-resistant and has strong resistance to downy mildew and anthracnose. But the cultivation conditions with sufficient fertilizer and water are required. The yield of summer and autumn cultivation is about 4000 kg per mu.

2. Xiafeng No. 1

Selected by Dalian Institute of Agricultural Sciences. The plant has strong growth potential and few branches. The leaves are large and dark green. Mainly to the main vine melon, the main vine 4-6 nodes began to sit melon, and then every 3 nodes out of a female flower. The melon strips are rod-shaped, the melon handle is short, the melon length is 36cm to 40cm, the skin is dark green, and the prickles are less. Melon meat is white-green, crisp, slightly sweet and of good quality. This variety is suitable for growing and fruiting under long-day conditions, and has strong heat and moisture tolerance. It has certain resistance to downy mildew and powdery mildew. It is suitable for cultivation in summer, with a yield of more than 2500 kg per mu.

3. Jinyan No. 2

It is selected and bred by the vegetable Institute of Tianjin Academy of Agricultural Sciences and has been popularized for many years. The plant grows strongly and the stem is stout. The leaves are enlarged and dark green. The main and lateral vines can bear melons, and the lateral vines are more than the main vines. When cultivated in summer and autumn, the main vine begins to bear melon at 10-12 nodes. Melon stick-shaped, 40-50 cm long, melon skin green, no edge, melon top with yellow stripes, thorns sparse, white thorns, thick skin, medium quality. Strong adaptability, heat resistance, resistance to downy mildew, powdery mildew, not resistant to Fusarium wilt. It is suitable for cultivation in spring, summer and autumn.

With cucumber planting method:

1. Soil selection and soil preparation before planting

Cucumbers like to be warm and not resistant to cold, wet and waterlogging. they should be planted in fertile, sticky sandy soil rich in organic matter and good drainage and water conservation. remember not to continue cropping with melons. When preparing the soil, pay attention to the deep trench high border, the general width of the border is about 1.8 meters, the height of the border is about 30 centimeters, double-row planting, plant spacing to maintain 25-30 centimeters.

2. Correct sowing, seedling raising and planting

The method of seed soaking and budding is widely used in cucumber planting. Spring sowing is generally used to sow seedlings after seed sowing or direct sowing with plastic film mulching, sowing in January-March, sowing in summer and autumn, sowing directly after sowing, sowing in June-August.

If the seedlings are raised in early spring, the seedlings can be raised in a small arch shed and transplant when the seedling age reaches two true leaves (about 15-20 days), and this work should be carried out in the evening on a sunny day. The most important thing to pay attention to when planting is not to hurt the roots, to ensure that the seedlings should be watered thoroughly before planting, and to plant them sequentially and with soil.

3. Fertilizer and water management

The application of sufficient base fertilizer is one of the key links to meet the requirements of high yield in cucumber planting, the principle of topdressing is a small number of times, and the use of farm organic fertilizer is advocated.

Cucumber needs a lot of water in spring, which is usually watered once a day in sunny days and irrigated for 3-5 days in a row in dry days, but attention should be paid to waterlogging prevention in rainy days.

Higher temperature in summer and autumn, faster growth and development of cucumber, coupled with large rainfall, rapid loss of fertilizer and water, so in addition to the application of basic fertilizer, but also depends on the situation, timely topdressing.

4. Increase the number of female flowers of cucumber.

Increasing the number of female flowers of cucumber means increasing the rate of fruit setting and then increasing the yield.

Specific methods such as:

Spraying triiodobenzoic acid in cucumber seedling stage, spraying sodium naphthylacetate after 2-3 true leaves of cucumber, or spraying ethephon after the first yellow leaf can increase the number of female flowers and control the number of male flowers.
