Efficient cultivation techniques of Cucumber in greenhouse

Cucumber is a common and very popular vegetable in the market, and it is also widely cultivated, including greenhouse and open field. Next, the editor will explain in detail the efficient cultivation techniques of cucumber in greenhouse.

First, apply basic fertilizer for land preparation

After the plot is selected, the weeds on the ground and the residual branches and leaves of the previous crops should be removed as soon as possible, and ploughing and tanning should be carried out as soon as possible. After the soil is dug, the sun should be no less than 2 days, and then the soil should be ploughed fine and leveled out. The base fertilizer should be mature compost, pig manure, cow manure, chicken manure, peanut bran, bean cake and other organic fertilizer. The base fertilizer is applied in the middle of the border. After fertilization, the soil is covered and the border surface is leveled.

Second, accelerate germination and sow seeds

Cucumber sowing seeds that can be directly sowed, soaking seeds to accelerate germination and then sowing, 2-3 days before sowing, seeds treated with seed coating agent should be dry sowed.

III. Seedling stage management

After sowing, we should pay great attention to the soil moisture, and the cucumber seedling stage requires soil moisture. After cucumber emergence, the mulch such as black gauze net should be removed to ensure that the seedlings receive enough sunlight. Cucumber seedlings also have diseases and insect pests, we should pay attention to observation, early detection, early prevention and control. Before emergence, the temperature in the greenhouse is about 30 ℃ in the daytime and 15: 20 ℃ at night, and after emergence, the temperature in the greenhouse is about 25 ℃ in the day and 13-16 ℃ at night.

IV. Timely planting and seedling fixing

The seedlings can be colonized from cotyledons to 4 true leaves, that is, when the seedling age is 8-25 days. The density of plastic film small arch shed is 3000cm / mu, double row planting, the row spacing is 25cm × 65cm, and the density of plastic film greenhouse should be slightly sparse, 2000cm / mu 2500 plants. Double row planting, the row spacing is 30 cm × 35 cm.

V. Field management

1. Fertilization management

The more commonly used fertilizers for topdressing are ternary compound fertilizer, urea and other kinds of chemical fertilizers, as well as organic fertilizers such as rotten livestock manure and urine. The methods of topdressing are trenching, burying and spreading, generally opening holes between two plants, and trenching should be 10 cm away from the base of the stem of the plant, and then apply fertilizer and cover it with soil.

two。 Water management

Three to five days after planting, more water should be drenched to keep the soil moist so as to facilitate the rapid recovery of seedling growth. When the seedlings have 3-4 true leaves, the water supply should be timely reduced and the humidity of the topsoil layer should be reduced. The water requirement of the plant increased from the tending period to the early fruiting stage, and the water should be drenched properly according to the soil moisture and weather conditions to keep the soil moist. In the peak fruiting period, the water requirement of the plant increases greatly, and the amount of water should be drenched twice a day during drought, so it is best to irrigate it every 3-5 days.

VI. Timely harvest

It takes 40-70 days from sowing to the first harvest of cucumber, and the whole harvest time is 30-60 days.

Because of its high yield and good economic benefits, greenhouse cultivation has become the main cultivation method in various places. Friends in need can plant according to the above methods.
