早熟西瓜一般在六月中下旬即可成熟,中晚熟西瓜在八月下旬至九月上旬成熟。由于中晚熟西瓜普遍采用地膜覆盖栽培,成熟期相应提早,八月中下旬即可成熟,十月份以后成为西瓜淡季。为了充分利用早熟西瓜收获后的生长季节,延长供应期,调节西瓜淡季,我们进行了早熟西瓜收获后的二茬西瓜栽培,取得了显著的经济效益。二茬栽培的具体措施一、选用抗病、早熟品种:选用抗病、生长势较强的早熟品种“p_2”,于三月中下旬播种,播后用小拱棚或大棚保温。六月中下旬可收获头茬瓜。
Early maturing watermelon generally mature in late June, late maturing watermelon mature in late August to early September. As the late-maturing watermelon commonly used mulching cultivation, the corresponding maturity earlier, mature in late August, October after becoming the off-season watermelon. In order to take full advantage of the growing season of early maturing watermelon after harvesting, extending the supply period and regulating the off-season of watermelon, we conducted the cultivation of the second crop of watermelon after harvesting the early maturing watermelon and achieved remarkable economic benefits. Second crop cultivation of specific measures First, the selection of disease-resistant, precocious varieties: selection of disease-resistant, strong growing potential of early maturing varieties “p_2”, sown in late March, after sowing with small shed or greenhouse insulation. The first crop of melon can be harvested in late June.
