西瓜嫁接栽培可克服连作障碍和防止枯萎病发生,主要技术措施如下: 一、嫁接砧末的选择 超丰F_1和庆发1号西瓜砧木成活率高,产量高,未发现死秧,对果实品质无不良影响,是理想的首选砧木。黑籽南瓜砧和勇士砧死苗率达5％～10％,南瓜砧有早衰现象,勇士砧极不耐涝且抗性差,不宜采用。其它葫芦砧均易发生不同程度的枯萎病和急性凋萎。 二、西瓜品种的选择 为发挥嫁接抗病、增产、高效的 Watermelon grafting cultivation can overcome continuous cropping obstacles and prevent the occurrence of Fusarium wilt, the main technical measures are as follows: First, the choice of grafting anvil End of Fung F_1 and Qingfa 1 watermelon rootstocks with high survival rate, high yield, no dead seedlings, fruit quality No adverse effects, is the ideal choice rootstock. Black Seed Pumpkin anvil and Warrior anvil dead seedlings rate of 5% to 10%, pumpkin anvil premature aging phenomenon, the Warriors are not very resistant to waterlogging and poor resistance, should not be used. Other gourd anvil are susceptible to varying degrees of wilt and acute wilt. Second, the choice of watermelon varieties To play grafting disease, increase production and efficiency
