由于我省西瓜生产面积迅速扩大,病害对生产的危害逐年加重,尤其土传枯萎病,到目前国内外仍无理想农药能控制发生。老瓜区用八年以上的轮作防治日趋困难,因此西瓜重茬“十种九瞎”的问题迫切需要解决。日本五十年代开始应用嫁接防治枯萎病,直到目前优良砧木仍在研究之中。我所于1982——1986年开题研究。重点是选择出适合北方嫁接技术,简化程序,研究嫁接高产栽培技术。研究指标是:应用选出的优良砧木嫁接成活率85％,抗病性强,在重茬地栽植亩产3000斤以上,品质无不良影响。85—86年被纳入省农业科技中试项目,85年用生统计算汇总中试数据,嫁接成活率平均达到88.5％,亩产4100斤,抗病性显著,品质无不良影响。86年各地面积都有相应增加。
Due to the rapid expansion of production area of watermelon in our province, the harm of the disease to the production has been increasing year by year, especially soil-borne Fusarium wilt. Up to now, there is still no ideal pesticide control at home and abroad. It is more and more difficult to control the cucumber area with the rotation of more than eight years. Therefore, the problem of “ten kinds of nine blindness” in watermelon re-establishment is in urgent need of solution. In the 1950s, Japan began to apply grafting to prevent and treat wilt disease. Until now, fine rootstocks are still under study. I was in 1982 - 1986 opening research. The key is to choose suitable for northern grafting technology, simplify procedures, research grafting high-yielding cultivation techniques. The research indexes are as follows: the grafting survival rate of the selected rootstocks is 85%, and the disease resistance is strong. 85-86 years was included in the pilot project of agricultural science and technology in the province, 85 years of health statistics summary pilot data, the average survival rate of grafting reached 88.5%, 4100 kg per mu, disease resistance significantly, the quality of no adverse effects. Over the 86 years, there has been a corresponding increase in the area.
