First, soil fertigation
Mu Shi quality decomposed organic fertilizer 10000?, Urea 9?, Superphosphate 80?, Potassium sulfate 6?, deeper than 25?. It is ridged by 80-90 ridge distance, 50-60 ridge width, and 10-15 ridge height.
Second, nursery transplanting
Selection of plants suitable for resistance to diseases, high stress resistance, good commodity traits, and high yield for grafting and seedling cultivation (black squash for rootstock selection), seedling age of about 40 days for transplanting and planting, 2 rows per ridge, plant spacing of 25 ft, Density 4000/mu or so.
Third, management
1, fertilizer and water management
After planting, the seedlings were poured with water. Later, depending on the situation, pouring water, no drought, no watering. Shenggua period appropriately increases the number of watering. The watering option is performed on a sunny morning, and it is not watered when it is cold or cloudy.
During the period of guaranty, the fertilizer was chased once every time, and 5 kg/mu of urea was chased each time. Sprouts topdressing potassium sulfate 8? At the same time, spraying 0.3%-0.5% of potassium dihydrogen phosphate and 0.5%-1% urea mixture sprayed about 10 days, can also spray foliar fertilizer.
2, temperature and humidity management
1 humidity. The relative humidity of the air in the shed shall be kept below 80%. Under the mulching of the mulching film and under the film, the air humidity in the shed may be effectively reduced. Use aerosol as far as possible to prevent pests and diseases to avoid increasing the air humidity in the shed.
2 temperature. The temperature in the shed is generally controlled at 10°C-30°C, that is, the temperature in the morning is not lower than 10°C, and the temperature in the noon is not higher than 32°C.
3, plant management
When the height of the plant is 25°, it is started to pull the rope to hang the vine. When the vine grows to the horizontal pull line, the vine spreads in time. When the vine spreads, the lower old leaves are removed first, leaving 15-20 healthy leaves.
Fourth, harvest
Root melon should be harvested in time to avoid embarrassment. Under normal circumstances, melon strips can be harvested when they are of sufficient length. In the case of cloudy days, when the temperature in the shed is not suitable for the growth of cucumbers, all the cucumbers above the medium level are removed to ensure the normal growth of the plants.
V. Pest Control
The prevention and control of cucumber diseases and pests in the solar greenhouse must also adhere to the principle of prevention and prevention. With physical control and biological control as the mainstay, supplemented by chemical control, the use of highly toxic and high-residue pesticides is forbidden, and safety intervals are strictly controlled to ensure product quality and safety.
Prevention of pests and diseases can be based on the addition of insect nets at the air outlets. Warm and boring sheds are used for 3 to 5 days. When the sheds are dipped, sulfur powder 2-3 kg/mu and trichlorfon 0.5 kg/mu are used first, and sawdust is mixed. The pile is ignited (the staff quickly withdraws from the shed after the medicine is ignited), and then the shed is closed. After the stuffy shed is over, colonization can be performed after the odorless release. After the plants have survived, the air humidity in the shed is reduced as much as possible to provide no suitable conditions for the occurrence of pests and diseases. Balanced fertilization and maintaining the appropriate temperature in the shed promoted the robust growth of the plants and improved their disease resistance.
Pest control:
The laying of insect nets can effectively prevent pests outside the shed from entering the shed. In the shed, aphids, migratory locusts, and spotted lilies can be killed by hanging insect traps. Smoke kills as an aid.
Disease prevention and control:
The downy mildew is fumigated with 45% chlorothalonil smoke agent 250g/mu, and sprayed with 72% Kelu wettable powder 800 times liquid or 69% ankang zinc wettable powder 1000 times liquid.
Bacterial keratoses were sprayed with 72% agricultural streptomycin WP 4000 times or WP.
Powdery mildew was sprayed with 10% of Shigao 1500 times or 40% of Fuxing Star Milk 3000 times.
If artificial flowers are used, it is necessary to grasp the concentration of the chemicals and strictly follow the instructions for use.
