Planting time and Management methods of Autumn Cucumber

Autumn cucumber is suitable for planting in early August, excellent varieties with strong resistance, less disease and high yield should be selected before planting; soak the seeds for 3-4 hours before sowing, cover a small amount of soil after sowing, and transplant about 5000 seedlings per mu; about 2500 kg of human feces and urine can be applied during growth; the soil should be watered in time when the soil is dry and drained in time when it rains. Dichlorvos EC and Bordeaux liquid can be used to control diseases and insect pests, and the work of setting up and binding vines should be done in the later stage.

Planting time of autumn cucumber

1. Autumn cucumber can be planted at the beginning of August, and the temperature in this period decreases slightly, which is beneficial to reduce the occurrence of diseases and insect pests.

2. The suitable temperature for the flowering and fruiting period of autumn cucumber is about 30 ℃, so it can avoid overgrowing and falling flowers and fruits, while planting in the south can be delayed a little longer.

Second, select improved varieties

The main results are as follows: 1. the temperature of autumn cucumber is slightly higher in the seedling stage, so it is suggested to select the excellent varieties with strong resistance, less disease and high yield.

2. Each place can make a choice according to the characteristics of local precipitation, temperature and disease. if you do not know how to choose, you can consult the experienced local farmers.

III. Sowing and transplanting

1. Autumn cucumbers generally use direct seeding, soak the seeds for 3-4 hours before sowing, and cover a small amount of soil after sowing, which is conducive to cooling and moisturizing. Or 6-7 days before sowing or planting, sowing fast-growing leafy vegetables in cucumber fields, such as water spinach and pakchoi, can protect seedlings.

2. When raising and transplanting seedlings, we should avoid hurting seedlings, carry out shallow planting with more soil, and replenish seedlings in time. The transplanting density is slightly higher than that of spring cucumbers. About 5000 plants per mu can be transplanted. The way of transplanting is deep ditch and high border, which is beneficial to timely drainage in heavy rain and irrigation in drought.

IV. Fertilizer and water management

1. The growth and fruit of autumn cucumber can be carried out at the same time, and the mature period is short and the growth is fast, so the base fertilizer can be used quick-acting fertilizer, generally, human feces and urine 2500kg or compound fertilizer 50kg can be applied per mu.

2. After transplanting, it can be combined with watering, and thin human feces and urine or quick-acting chemical fertilizer can be applied every 5-7 days, and nitrogen and phosphorus fertilizer can be applied outside the root after autumn cucumber is harvested in full fruit period.

3. Autumn cucumber needs a lot of water in summer and autumn, but it can not be waterlogged. If it is not properly irrigated, it is easy to induce diseases and reduce the yield of autumn cucumber, so irrigation should be controlled flexibly to ensure timely drainage under heavy rain. Drought ditch irrigation "horse race water", along with irrigation along with drainage.

V. Prevention and control of diseases and insect pests

1. Autumn cucumber has more insect pests and occurs earlier, which is the main factor affecting yield, so it is necessary to pay close attention to prevention and control from the seedling stage, the main pest in the seedling stage is Huangshou melon, during which 1000-1200 times of dichlorvos EC or 1000 times of 90% crystal trichlorfon can be sprayed and killed.

2. In addition, aphids also need to be controlled. Autumn cucumbers are prone to downy mildew, which can be prevented by spraying 0.5-0.8 Bordeaux solution during the period.

VI. Setting up and harvesting

The main results are as follows: 1. In order to do a good job of setting up and binding vines and harvesting in the later stage of growth, autumn cucumber has a short growth period and fast plant growth, so it is necessary to set up and bind vines as soon as possible.

2. Due to the high temperature in summer and autumn, the fruit is prone to aging, so it needs to be harvested in time. Generally, it can be harvested 40-50 days after sowing, and then every 3-5 days.
