Detailed Guide to Raising Dry Cucumbers in Spring Greenhouses
Generally sow in late February to early March, choosing early-maturing varieties that are high-yielding, disease-resistant, tolerant of low temperature and weak light, and have good market quality. Before sowing, prepare the nutrient soil, add an appropriate amount of superphosphate and diammonium phosphate to the nutrient soil, and be sure to disinfect the nutrient soil after it is prepared; before sowing, disinfect the cleaned seeds, soak them in 55°C...

Planting method for interplanting peppers with spring cucumbers in a greenhouse
What standards should age-appropriate strong seedlings of spring cucumbers in a greenhouse meet? When is the best time to plant them? In greenhouse spring cucumber production, to improve economic returns, harvesting as early as possible is required, and planting must wait until the ground temperature has steadily passed 10°C, so only by planting larger seedlings can the goal of early maturity be achieved. Planting smaller seedlings in the greenhouse can eas...

Detailed Explanation of Multi-Layer Covered Seedling Cultivation Technology for Cucumbers in Spring Greenhouses
1. Do not arbitrarily change the light-receiving angle of the greenhouse. The angle of the solar greenhouse currently used for cucumber cultivation has been scientifically verified over a long period. Its north-south span, height, and rear slope angle should not be arbitrarily changed. 2. Do not apply concentrated fertilizer at transplanting. Various chemical fertilizers, especially nitrogen fertilizers, under humid and high-temperature conditions, will produce large amounts of...

Key Points of Greenhouse Cucumber Management Techniques After Spring Festival
Manage Fertilizer and Water Well In mid-to-late February, most greenhouse cucumbers enter the peak fruiting period, and their demand for fertilizer and water gradually increases. Therefore, topdressing cucumbers should preferably be carried out after the end of February, generally applying 20 kg of urea, 5-8 kg of monopotassium phosphate, or 30-35 kg of potassium sulfate compound fertilizer per 1/15 hectare, once every 20...

Integrated Pest and Disease Control Methods for Greenhouse Cucumbers in Spring
I. Common Diseases in Spring 1. Downy mildew (1) Occurrence characteristics: persistent (long-term companion), devastating (rapid spread, outbreaks). (2) Occurrence conditions: High humidity: relative humidity above 83% favors disease development, (water droplets or water film on leaf surface), spore germination and invasion. Optimum temperature: 15-20°C. Nutritional status...

Key Technical Points for Multi-Layer Covered Seedling Raising of Cucumbers in Spring Greenhouses
I. Greenhouse Structure. The best span for the greenhouse is 6-8 m. Put on the greenhouse film in early November. Set up a 1.5 m low tunnel inside the greenhouse and cover it with 3 m wide greenhouse film. At night, cover the low tunnel with a thick straw mat, and add a layer of old greenhouse film over the straw mat, which greatly enhances heat preservation. After seedling raising, cucumbers can still be planted in the greenhouse. II. Nutrient...

What are the winter management measures for water spinach in greenhouses?
1. Deeply plow the land, apply sufficient base fertilizer, and keep the soil merely moist. Adjust the temperature according to the needs of the plants. Spraying New High Lipid Film can effectively prevent aboveground moisture from evaporating and seedling moisture from transpiring, shorten the seedling recovery period, and help the plants quickly adapt to the new environment and grow healthily. 2. Water reasonably, fertilize in a timely manner, cultivate and weed,...

Detailed Explanation of Key Techniques for Winter Plastic Greenhouse Cultivation of Water Spinach
Water spinach is widely cultivated throughout our province and is a major green leafy vegetable that fills the gap in summer and autumn. Water spinach likes high temperatures and high humidity, has strong heat tolerance, and is not tolerant of frost; when frost occurs, the stems and leaves wither and die. The optimum growing temperature is 25-30°C, and growth stops below 10°C. Therefore, plastic greenhouses should be used for off-season cultivation in winter. 1. Varieties...
