Watermelon, the choice of cultivation is the key

    Planting watermelon, it has strict requirements on many aspects such as mouthwash, topography and soil condition. Therefore, it is necessary to pay attention to scientific and rational selection of land before planting watermelon.

Cultivating watermelon

    1 , choose the mouth

    Watermelon has strict requirements on the crops planted in the previous crop. The cultivation of watermelon must pay attention to scientific rotation and avoid long-term continuous cropping. For the first crops of watermelon, it is best to harvest cereals such as wheat, corn and sorghum, which are relatively early and have a long leisure period, followed by cotton and sweet potatoes. Note that the plots of watermelons are not allowed to be beans and peanuts. And other crops. According to the survey, the cultivation of watermelon in the soybean meal is the most serious, and the rate of plant infection with this disease is as high as 45 percent, while the corn borer is relatively light, and the disease rate is about 20 percent.

    2 , select the topography

    Watermelon is more resistant to drought, avoids humidity, and is afraid of phlegm. The plots that cultivate watermelon need high-lying, dry, flat, and convenient drainage.

    3 , choose soil

    Although the adaptability of watermelon to soil is relatively wide, it can grow in sandy soil, paddy soil, clay, red loam soil, freshly cultivated wasteland and new reclamation shoal soil, and grow better in soil with pH value of 5 to 7 . It can also grow normally in saline-alkaline soil with a salt content of less than 0.2%. However, watermelon roots have significant gas permeability, and it is best to choose deep, fertile, loose loam or sandy loam in the soil.

    4 , choose neighbors

    In the process of planting watermelon, mosaic disease is one of its most important diseases, and its source of poison mainly comes from zucchini and melon with earlier onset. Therefore, it is best not to grow watermelons adjacent to the two crops.
