Recently, the reporter interviewed in Xiyue Village, Dongxia Township, Qingzhou City, and found that most of the vegetable farmers in the village used the “watermelon + bitter gourd + spinach†planting model. It is understood that this model has a reasonable cornice arrangement and a high planting efficiency, which is of great value for promotion.
The cornice arrangement of this planting pattern is as follows: the first watermelon is sowed in the early February nutritional pods, planted in early March, and pulled out in mid-June; the second pod is planted in the nutrition pods in early June, and is planted in late June, and October In the middle of the pull out of the park; the third round of spinach live in late 10, 12 early gardening.
Before the seeds of watermelon and bitter gourd are sown, they must be sterilized. The seeds can be soaked in warm water of 55°C for 10-15 minutes and continuously stirred. When the water temperature drops to 32°C, keep the water temperature and soak for 4-5 hours before soaking. Wrap it in a wet cloth and place it in an environment of 28-32°C. Seeds can be sown after breaking the mouth by 60%. After the seedlings are unearthed, the most important thing is to regulate the temperature. Generally, the temperature should be controlled at 26-35°C during the day and the temperature should be controlled at 16-18°C during the night. After the seedlings grow up, the temperature can be lowered by 2-3 °C and the low-temperature hardening seedlings can be used. In order to cultivate strong seedlings, it is possible to use 0.2% potassium dihydrogen phosphate to mix 6000 times more foolproof foliar spray.
Before each planting, the soil should be deep-rooted and the base fertilizer should be applied. Generally, 5000-6000 kg of farmyard manure and 50-100 kg of compound fertilizer should be applied to each mu of land, then soil preparation, ridge cultivation, and watermelon row spacing should be applied. 200 centimeters, 50 centimeters of plant spacing, planting about 600 plants per acre; bitter gourd spacing of 2 meters, plant spacing of 1.50 meters, planting about 200 plants per acre.
Watermelon and bitter gourd basically have the same requirements for the temperature in the greenhouse. Generally, the temperature should be controlled at 25-35°C during the day after planting and 15-18°C at night. After the planting, the fertilizer and water management can adopt the “pre-control and post-accelerated†approach. Generally, no watering is required after the pouring of enough water after the planting and before the squashing. The soil in the shed can be poured into the water under the membrane when the soil is dry. After the melon period, the topdressing can be carried out for the first time. The topdressing can be flushed with water. It is advisable to apply 15-20 kg of compound fertilizer per acre. After that, the fertilizer can be flushed once every other time.
The main diseases of watermelon and bitter gourd are downy mildew, bacterial blight, powdery mildew and epidemic diseases. When the disease is first developed, 58% of metalaxyl manganese zinc or 69% of enoyl manganese zinc can be used for downy mildew and epidemic diseases. (Anke) 1000 times prevention and control; 75% of chlorothalonone can be used to control bacterial blight DT500 times mixed; powdery mildew available 62.2% of myclobutanil. Mancozeb (Xiansheng) 600 times prevention and treatment.
After the second bitter gourd garden is pulled out, it is necessary to clean up the garden in time, no need to turn over the fertilizer, direct spinach directly in the shed, spinach spacing of about 10 cm. After the sowing, the water is poured once and it is not necessary to fertilize it again during the period of time. It can be harvested after about 50 days.
