How to efficiently grow multiple crops of cabbage, sweet potato slips, eggplant and cauliflower in succession?
Lettuce prefers a cool environment and tolerates neither cold nor heat well. Therefore, to grow lettuce successfully, the following technical steps should be mastered. 1. Variety selection. For planting lettuce, choose varieties with good cold and heat tolerance and strong stress resistance, such as head lettuce, glass lettuce, curly-leaf lettuce and Caesar, which are better choices. 2. Soil...

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...

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...

Detailed Explanation of Key Techniques for Increasing Yield by Grafting Multiple Pumpkin Plants Together
If too much nitrogen fertilizer is applied in the early growth stage, the plants tend to grow excessively, causing flower and fruit drop, and it becomes impossible to ensure uniform fruit set and the final product quality. Therefore, the amount of nitrogen fertilizer used should be controlled, and the proportion of phosphorus and potassium fertilizers should be appropriately increased. When needed, chemical treatments can be used, such as selecting Zucchini Fruit Set King 1...

High-Efficiency Cultivation Technique for Multiple Cropping of Winter Lettuce Followed by Early Spring Peppers in Greenhouses
For lettuce, choose the disease-resistant, high-yielding, cold-tolerant lettuce variety Shuiguasi. Sow and raise seedlings in a small arch shed from late August to late September. After sowing, lower the temperature during the day by ventilating the shed film from the bottom and covering with a shade net; on rainy nights, cover the shed film properly. From pricking out to the seedling recovery stage, shade during the day to create an ambient temperature suitable for lettuce growth...

High-Efficiency Multiple Cropping Technique for Winter Lettuce and Early Spring Peppers in Greenhouses
1. Select good varieties: For greenhouse cultivation of early spring lettuce, it is advisable to choose early-maturing pointed-leaf varieties with strong cold resistance, such as Hefei pointed-leaf duck-egg lettuce and Beijing crucian carp lettuce. 2. Grow strong seedlings: Sow and raise seedlings in a greenhouse in mid-to-late January. Before sowing, first soak the seeds in clean water at 20°C for 3-4 hours, rub and wash them, then remove and drain the water, and put them into...

High-Efficiency Multiple Cropping Technology for Greenhouse Lettuce, Thick-Skinned Melon, and Green Garlic
In the multiple cropping model of greenhouse lettuce, thick-skinned melon, and green garlic, lettuce is sown and raised as seedlings in mid-to-late September, transplanted in late October, and harvested in mid-March; thick-skinned melon is sown and raised as seedlings in late February, planted out in late March, and harvested at the end of June and the beginning of July; green garlic is sown in late July and harvested in mid-to-late October. Per mu, the yield can reach 4500-500...

Detailed Explanation of the Technique of Taking Multiple Shoots from a Single Seedling for Grafting Eggplant
In autumn, temperatures are high, the weather is dry, and the temperature difference between day and night is large. Eggplant suffers severe flower and fruit drop, growth and development are hindered, and stiff fruits and deformed fruits are prone to appear, resulting in low yield and poor quality. Management must be strengthened to ensure high yield and good quality and to obtain a good harvest. Strengthen water management. In autumn, eggplant plants should be watered every morning and evening...

Detailed Explanation of the Multi-Bud Scion Harvesting Technique from a Single Seedling for Eggplant in Protected Cultivation
Grafting cultivation of eggplant has become the most important disease-resistant and yield-increasing cultivation method in current protected eggplant production. When raising grafted eggplant seedlings, the one-seedling-one-bud scion harvesting technique is generally used, but this method involves high seed costs and high production costs. For this reason, based on the principle of apical dominance in plant growth and combined with the characteristic of strong lateral bud sprouting in eggplant seedlings...
