Key points of cultivation techniques for organic cucumber in summer and autumn

Summer and autumn cucumber cultivation in the open field, low production cost, simple planting technology, no risk, and good economic benefits, but due to the impact of the weather, it sometimes leads to poor production. To do a good job in summer and autumn cucumber cultivation should master the following key technologies. Let's learn about the cultivation techniques of organic cucumber in summer and autumn.

Variety selection

Sowing from mid-May to late June, some are called summer cucumbers, and the varieties with strong plant growth, disease resistance, heat resistance, sorghum resistance and high yield are selected. In mid-July, live broadcast or seedling transplanting, some called autumn cucumber, should be used with strong adaptability, high temperature resistance during seedling stage, low temperature resistance and strong disease resistance.

2. Seeding seedlings

It is better to use seed soaking and germination sowing than dry seeds. On the sides of the sorghum, use a small ditch of 10 to 12 cm wide and 10 to 15 cm deep, and fill the ditch with water. When the water will be infiltrated, it will rush. The seeds were planted with 2 seed buds at a distance of 25 cm from the plant, covered with wet soil, and then flattened. If it is rainy, it is advisable to cover the sand after sowing. After sowing, it is rainy, and the iron shovel is used to draw the surface.

3. Soil preparation and fertilization

Choose loam that can be irrigated and breathable. It is best to apply more decomposed round fertilizer, compost or crushed crop straw. Generally, 5000 to 7500 kilograms of fermented farmyard manure per mu is used as base fertilizer, 100 kilograms of cake fertilizer, 50 kilograms of phosphate rock powder and 20 kilograms of potassium ore powder. Fine soil preparation, made 1.2 to 1.5 cm wide sorghum or semi-high sputum.

4. Cultivation of strong seedlings

The live seedlings grasped the cultivating soil after the seedlings were unearthed. When the seedlings are deficient in water, they should be watered in time, and a small amount of seedling fertilizer should be applied in conjunction with watering. When the ground is slightly dry after the rain, it is necessary to cultivate the loose soil and weed in time. Topdressing in the seedling stage should be carried out before the rain or before watering, and 500 kg of fermented manure per acre. If there is too much rain, the soil nutrients are lost, and the seedlings are yellow and thin. The organic nutrient solution can be applied in combination with the sprayed roots in the field. After emergence, in order to reduce the ground temperature, grass cover measures can be taken. On sunny days, the ground temperature under 10 cm can be lowered by 1 to 2 ° C, and the cloudy day can be reduced by 0.5 to 1.0 ° C, and the soil compaction can be prevented and the loose soil work can be reduced. If you have the conditions, you can also cover the insect-proof net in the frame, which can not only cool the air, but also prevent pests on the ground.

5. Fertilizer management

The temperature in summer and autumn is high, the soil moisture evaporates quickly, and the transpiration of cucumber plants is large. It should be noted that the number of watering should be increased, but the amount of water should not be too large. The watering should be carried out in the morning or evening, preferably the well water is not filled. The 10 cm ground temperature can be lowered by 5 to 7 °C. Under the overheating rain, it should be drained in time, and immediately flushed with well water, commonly known as 涝 pouring garden. After the melon is placed on the melon, the top dressing is applied, and the per-mu is dried or the decomposed chicken manure is 400-500 kg. After the root melon is harvested, the second top dressing is followed by 2 to 3 times of catching the fertilizer, and each time the per mu is applied with 500 kg of manure.

6. Racking vines

When the cucumber seedlings grow to 7 to 8 leaves, the plants are 20 to 25 cm high, and must be inserted into the frame. The insertion frame should be inserted into the fence flower stand, and each bamboo raft is at least staggered with 4 pieces, which is beneficial to the melon vine. Summer and autumn cucumber plants grow faster, it is necessary to tie the vines in time, the lower side vines generally do not stay, the middle side vines can leave more leaves and then pick the heart as appropriate. Timely to remove the lower old leaves and diseased leaves. In addition, autumn irrigation is more, easy to produce weeds, should pay attention to timely removal.
