1. Preparation for broadcast
The choice is for high-temperature, disease-resistant, flood-resistant, high-yielding and high-quality summer cucumber varieties. For example, no. 4 and 5 of jin chun, no. 8 of china。
2. Fertilizing the whole area
Cucumber cultivation in the summer is based on the choice of ventilatory, water-watering conditions and better drainage, and on plots that have not grown melon crops in the previous three years. A combination of 90,000 kg of manure per hectare, 600 kg of calcium phosphate, 300 kg of ammonium carbonate, 75 kg of multi-element boron manure, flattening, approximately 1 m wide, tanning and seeding。
3. Sterilization
1 hot soup impregnated seed. After sunbathing from 2 to 3h, seeds are placed in 60°c warm water and are constantly mixed, so that the water temperatures are reduced to 30°c and impregnated to 4h, and soaked with wet gauze in 30 to 35°c, half of the seeds are seeded in white。
2 sterilized. It is impregnated by 500 times more than 50% more fungus of filamentable powder; or mixed by 4% of seed weight with 50% more fungus of humid powder; or mixed by 3% of seed weight with 25% of venomeous humid powder。
4. Cultivation due
The cucumber seeding time is usually in mid-may and late in may. It is possible to sow seeded directly by impregnated seed seed, with two rows per cucumber, at a distance of about 25 cm, and two to three seed seeds per den, with approximately 50,000 dens per hectare and a back-sliding membrane。
5. Field management
When the meadows come out of the top of the earth, they break in time, and when the weather is dry, water should be poured at night. 7d seedlings, with one strong seedling in each den and one water pouring after planting. When cucumber saplings have three to four leaves, it is necessary to insert a fixed frame and get the chicken on board. When the chicken is tied, it stretches back to the top of the shelf, prolongs the main chicken in order to inhibit its growth, evenly spread the chicken on the shelf and stimulates the multimelting and timely removal of corsets and sick and old leaves。
6. Management of the melon period
The cucumbers are growing well in the summer, require water, are fattening, and there is more rainfall during this period, and soil nutrients are prone to loss, so water is poured every 57d and fat every two times. A mixture of 225 kg of compound fertilizer or urea per hectare, 225 kg of potassium fat, and 3 per cent of potassium phosphate and 3 per cent of urea were sprayed on the leaves. It should take place in the evening or in the morning, and it is not appropriate to do so at noon. In the case of high-temperature droughts, water is poured every second to two d and is drained and protected against flooding in the event of successive or heavy rains. Hot rain is followed by the timely cooling of wells。
