How to efficiently cultivate greenhouse cucumbers, rice, and spinach?
Spring spinach has a relatively short growing period, and can generally be harvested and sold 30 to 50 days after sowing. Planting spring spinach plays an important role in quickly alleviating the spring vegetable shortage. Choose suitable varieties. After spring spinach is sown and emerges, temperatures are low and daylight gradually lengthens, making it very easy for bolting to occur once it passes through phase development. Therefore, choose varieties that bolt late, have thick and broad leaves...
In recent years, Beigou Town in Xinyi City has vigorously promoted an efficient cultivation model of early spring greenhouse cucumbers, rice, and spinach, producing 3,500 to 4,000 kg of cucumbers, 600 kg of rice, and 1,500 kg of spinach per mu, with an annual net income per mu reaching 7,000 to 8,000 yuan.Cucumbers Select sandy loam paddy fields with fertile soil and good drainage and irrigation conditions for planting. Use high-yielding, high-quality, cold-tolerant varieties such as Changchun Mici and Luwang. According to the shape of the field, build large arched greenhouses of 0.4 to 0.5 mu each in early February. Apply 2,500 kg of decomposed farmyard manure, 50 kg of compound fertilizer, and 15 kg of urea per mu as base fertilizer. Raise seedlings in mid-February and transplant in early March. Cover the greenhouse 20 days before planting, use wide and narrow row cultivation, with a wide row spacing of 70 cm, a narrow row spacing of 50 cm, and a plant spacing of 25 cm, planting 4,500 plants per mu. After planting, cover with plastic film, and manage heat preservation and ventilation according to climatic conditions. Remove the film in May and switch to open-field management. Pay attention to preventing and controlling cucumber downy mildew and gray mold. Harvesting is completed around June 20.
Rice Use high-yielding, disease-resistant varieties such as Xudao 3, Xudao 4, and Yanjing 8. Soak seeds with imidacloprid or Shibaike pesticide before sowing. Use the technology of dry seedlings in fertile seedbeds, sow around May 5, pay attention to cultivating strong seedlings and preventing excessive growth. Finish transplanting by the end of June, planting 25,000 to 28,000 hills per mu, and use population quality cultivation technology throughout the growth period. Pay attention to preventing and controlling rice stripe leaf blight, rice blast, rice leaf roller, and other pests and diseases. Harvest at the end of October.
Spinach Choose drought-resistant, cold-tolerant, fast-growing, high-yielding pointed-leaf varieties, such as Shuangcheng pointed-leaf and Qingdao spinach. Use 5 to 6 kg of seed per mu, broadcast it in the paddy field about 15 days before rice harvest, and pay attention to waterproofing and heat preservation. After the rice is harvested, apply 2,000 kg of farmyard manure per mu, and cover the spinach with soil to protect the seedlings. Apply urea as a topdressing 20 to 30 days before harvest, water appropriately, and cover with small arched greenhouses for heat preservation. Bring to market in batches around New Year's Day, and finish harvesting by the end of January.
