Watermelon, as a summer fruit, is deeply loved by people. In the process of planting, the cultivation of watermelon seedlings is a crucial link. This article will introduce the planting and management methods of watermelon seedlings in detail, in order to provide reference for growers.
1. Planting of watermelon seedlings
1.Seed selection.
Choosing watermelon seeds with good quality, high yield, and strong disease resistance is the key to successful planting. According to the local climatic conditions and soil characteristics, suitable varieties are selected.
2.Seeding time.
Spring is the best time to sow watermelons, depending on the local temperature. In general, when the temperature stabilizes above 15, sowing can begin.
3.Seeding method.
Soak the selected seeds in warm water at 55 °C for 10-15 minutes, then remove and dry. To sow seeds, dig a hole 5-8 cm deep in the soil, then lay the seeds flat in it and cover the soil with compact. The sowing spacing should be 20-30 cm.
4.Soil & Fertilization.
Choose deep, fertile, well-drained land for planting. Before sowing, the land needs to be deeply cultivated and an appropriate amount of organic fertilizer should be applied, such as well-rotted farmhouse fertilizer.
Second, the management of watermelon seedlings
1.Watering and weeding.
After sowing, it is necessary to water in time to keep the soil moist. During the growing period, water at the right time according to weather conditions and soil moisture. At the same time, it is necessary to pay attention to timely weeding to prevent weeds from competing with watermelon seedlings for nutrients.
2.Temperature control.
Watermelons need the right temperature to grow. When the temperature is low in spring, it is necessary to pay attention to taking thermal insulation measures, such as building small arch sheds. When the temperature is too high in summer, it is necessary to do a good job of shading and cooling.
3.Pest and disease control.
Regularly inspect the growth of watermelon seedlings, and take timely control measures if pests and diseases are found. Common pests and diseases include powdery mildew, aphids, etc., which can be controlled with corresponding pesticides. At the same time, it is necessary to pay attention to reasonable dense planting, keep the field ventilated and light-transmitting, and improve the disease resistance of plants.
4.Harvesting and storage.
When watermelons are ripe, they should be harvested in time. When harvesting, care should be taken to avoid damaging the melon vines and fruits. After harvesting, watermelons should be stored in a cool, dry place, away from direct sunlight and moisture. During storage, pay attention to maintaining good ventilation to prevent the occurrence of diseases.
5.Variety renewal and improvement of planting techniques.
With the development of agricultural science and technology, new varieties and planting techniques are constantly emerging. Growers should pay attention to relevant information, keep abreast of new technologies and new varieties, and improve planting efficiency. At the same time, it is necessary to adjust the planting structure and improve product quality and output according to market demand and consumer preferences.
6.Utilization of agricultural waste and environmental protection.
In the process of watermelon planting, some agricultural wastes will be generated, such as dead branches and leaves, waste agricultural film, etc. These wastes can be disposed of through composting, reuse, etc., turning waste into treasure. At the same time, it is necessary to use chemical fertilizers and pesticides rationally to avoid pollution to the environment. In the process of planting, it is necessary to pay attention to protecting the ecological environment and maintaining ecological balance.
3. Analysis of economic and social benefits
Through scientific planting and management methods, the yield and quality of watermelon can be improved, and better economic benefits can be brought to growers. At the same time, the cultivation of watermelon can also drive the development of related industries, such as agricultural machinery, agricultural material sales, etc. In addition, the cultivation of watermelons can also provide employment opportunities, increase farmers' incomes, and promote rural economic development. While meeting the market demand, it also provides consumers with healthy and high-quality food. Therefore, watermelon cultivation has significant economic and social benefits.
To sum up, the planting and management of watermelon seedlings is a comprehensive work, which requires comprehensive consideration of multiple factors. Through scientific planting methods and management methods, the yield and quality of watermelon can be improved, and more benefits can be brought to growers and consumers. At the same time, we should also pay attention to environmental protection and sustainable development, and achieve the dual goals of economic and social benefits.
