The fruit cucumber is mainly cultivated in protected land, suitable for greenhouse heating in autumn and winter, winter and spring greenhouse and spring greenhouse cultivation. The cultivation points are as follows:
When cultivating seedlings and seedlings, it is advisable to adopt precision seeding and one seedling. The seedbed can be made of horse dung hot bed or electric hotbed. The seedling temperature is more stringent, the optimum germination temperature is controlled at 24-26°C, and after emergence, it is maintained at 23-25°C during the day and 15-18°C at night. The nutrient soil of the seedbed is prepared with decomposed horse dung, furnace ash, etc. to achieve both loose and fertile requirements.
Soil preparation and planting fruit cucumbers have high yield, large leaves, and early fruiting period. However, the roots are shallow, and the ability of sucking fertilizers is weak. Therefore, fine-tillage soil preparation is required before planting, and soil improvement is best for growing greenhouse vegetable plots. The specific method is to add 20% of decomposed livestock manure and 30% of sand or furnace ash to the soil in a greenhouse with a depth of 24-30 cm, mix well and apply 50 kg/mu of potassium sulfate compound fertilizer to the tillage layer to reach the soil. Loose and fertile, waterless, conducive to the growth of the root soil environment. The spacing of the cultivars was 35 cm x 70 cm, and the seedlings were watered immediately after planting.
Field management temperature management: After planting, multiple measures such as covering and heating can be used to maintain a higher temperature and humidity in the shed, which will facilitate the easing of seedlings. Keep 32-35°C during the day, 17°C at night, cool after a week of incubation, keep it at 30°C during the day and 16-18°C at night.
Moisture management: After 5-7 days of planting, slowly pour the seedlings with water once. When watering, look at the weather. Normally watering on sunny days, the time is better at 6-8 am (noon of overheated pouring cold water is harmful to the root system, afternoon or evening Watering is likely to cause humidity in the shed, low soil temperature and cause disease. No watering is allowed on rainy days.
Light and ventilation: The fruit cucumber is resistant to weak light and can obtain high yields in low light conditions. In summer, high temperature and strong light should be covered with shade nets. In the management of greenhouses, the temperature and humidity in the greenhouse should be adjusted by ventilation, and the relative humidity should be controlled at about 60% to prevent the disease caused by excessive humidity.
Fertilization: Combine watering for fertilization. In the melon period, take the principle of “water and fertilizer†and “eat less and more mealsâ€. In the middle and late stages of the melon, when the roots are weak in fertility, they need to be combined with 0.2%-0.3% phosphoric acid. Potassium hydrogen solution is applied outside the roots to prevent premature aging.
Harvest: The fruit grows rapidly, about 45 days from sowing to commercial melon picking. Generally the roots do not leave melons, and the young melons are removed in time to facilitate the growth of the plants. Because the earthworm grows stronger, the melon grows faster. It will affect the time of harvesting and listing. Pre-merchandise melons should also be harvested earlier to increase the previous production.

There is no doubt that solar monitoring has brought great convenience to people. It saves a lot of manpower and material resources without having to stick to the post for 24 hours as before. Not to mention that the current surveillance cameras have the function of motion detection. As long as someone enters a certain range, it will automatically alarm and capture the scene. What is the function of the solar monitoring system?
1. Solar panel: The solar panel is an important part of the mobile phone software of the solar power generation system, and also a part of the practical value of the mobile phone software of the solar power generation system. Its function is to convert the professional ability of radioactive substances in natural light into electric energy, or send them to storage batteries, or promote load work.
2. Solar controller: The solar controller is used to control the operation of mobile phone software in all systems, and has the functions of overcharge protection and overcharge maintenance for the battery. In areas with large temperature difference, the qualified controller shall also have the function of temperature compensation. In the mobile phone software of the solar road lamp system, there must be light control switch and time control solar road lamp operation.
3. Battery: generally valve controlled maintenance free lead-acid battery. In the mobile phone software of small and medium-sized systems, in cold weather areas, a solar gel battery needs to be configured, which can be used at low temperatures, with high efficiency and is not vulnerable to major damage. Its function is to store the electric energy of the solar panel when the sun shines, and then release it under certain conditions.
4. Variable frequency power supply: split wave type and sine wave type. In order to provide power for 220VAC electrical products, it is necessary to convert the DC stabilized voltage power supply in the solar power generation system software into AC circuit energy, so DC AC variable frequency power supply is required.
