西瓜生长期短、效益高。但一般西瓜忌连作,瓜农责任田有限,倒茬不过来。中国农科院新近推出两个特抗病品种:①“郑抗1号”:抗枯萎病、耐重茬(重茬三年瓜园无死秧)、高产优质。它在河南、河北、山东、山西等省种植,瓜农反映很好。②“郑抗2号”:是国内唯一早熟抗病品种;易座瓜,品质优,形似“新红宝”。经多地试验,重茬基本无死秧,很有发展前途! Watermelon growth period is short, high efficiency. However, in general, watermelon avoid continuous crop melon agriculture limited responsibility, but the crop. Chinese Academy of Agricultural Sciences recently introduced two special disease-resistant varieties: ① “Zheng Kang 1”: Fusarium wilt, resistance to stubble (heavy crop three years Guayuan no dead seedlings), high yield and quality. It is planted in Henan, Hebei, Shandong, Shanxi and other provinces, melon farmers reflect well. ② “Zheng Kang 2”: is the only precocious disease-resistant varieties; easy seat melon, excellent quality, shaped like “new Ruby.” After many experiments, stubble basically no dead seedlings, very promising!
