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...

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...

Potato and scallion multiple cropping can achieve two harvests from one field
I. Cultivation of the preceding potato crop 1. Variety selection The potato variety suitable for potato-scallion multiple cropping in the Xiongyue area is "Dongnong 303", with 15 kg of seed used per mu, maintaining 4500 plants. 2. Deep plowing and fertilization In autumn, plow the soil to a depth of 15-20 cm, harrow the soil in spring, and apply 4000 kg of high-quality organic fertilizer per mu as base fertilizer. 3. Seed potato sprouting In early March, place the selected seed potatoes in a greenhouse or on a heated kang to sprout for about 10 days. Cut the seed potatoes into pieces of 20-30 g, and after cutting, air-dry the seed pieces for 6-12 d, then they are ready

Detailed Explanation and Application of the New Muskmelon-Rice Multiple Cropping Technique
I. First Crop Muskmelon 1. Seed selection and land preparation: Choose high-yield, high-quality muskmelon varieties with a growing period of about 90 days, such as Chaozhao Tangwang and Hongchengcui No. 1. Before the ground freezes the previous year, plow the paddy field well, harrow, press and form ridges with a ridge spacing of 50-60 cm, and press firmly to preserve soil moisture. Along with land preparation, apply 5000 kg of high-quality farmyard manure per mu. 2. Seedling raising and transplanting: Soak seeds to promote germination in late February, raise seedlings in a greenhouse in late February to early March. You may use seedbed seedling raising followed by pricking out into seedling bowls, or directly raise seedlings in seedling bowls. For planting melons in the main field, transplant the melon seedlings into the main field before April 15.
