黄瓜嫁接可防治黄瓜枯萎病、疫病等土传病害,增强抗性,一般增产20—30%.我们以黑子南瓜为砧木,接山东密刺、长春密刺等黄爪.一、接前准备(一)配养土 肥沃壤质土6份,腐熟有机肥4份,每立方米加大粪于20kg,复合肥1.5kg,草木灰5kg,多菌灵80g,掺匀过筛备用.(二)种子处理 黄瓜种按常规浸种催芽、播种,黑子南瓜休眠期较长,当年新子出芽率仅50—70%,可先放入0—4℃冰箱中冷却24小时,促其度过休眠期.然后用70℃温水浸泡15分钟,降至常温,浸泡12小时,再催芽播种.(三)播种 靠接法黄瓜早播7天左右.插接法和劈接法南瓜早播3—4天,最好播在营养钵内.靠接法的南瓜和黄瓜都可播在育苗盘(箱)中,南瓜的密度要大,以使其下胚轴变细,和黄瓜相适应.
Cucumber grafting can prevent cucumber wilt disease, disease and other soil-borne diseases, enhance resistance, the general increase of 20-30% .Summer pumpkin rootstocks, thenShandongSpatius, A) with soil fertile loam 6 soil preparation, composting 4 parts of organic fertilizer, add manure to 20kg per cubic meter, compound fertilizer 1.5kg, ash 5kg, carbendazim 80g, mix well sift spare. Cucumber species by conventional soaking seed germination, sowing, suckling pumpkin longer dormancy, when the new seed germination rate of only 50-70%, can be placed in a 0-4 ℃ refrigerator for 24 hours to promote its passing through the dormant period. 70 ℃ warm water soak for 15 minutes, down to room temperature, soak for 12 hours, and then germination sowing. (C) planting seeding method of cucumber early sowing about 7 days. Sowing in a nutrition bowl, the pumpkin and cucumber that are attached to each other can be sown in a nursery pan (box), and the density of the pumpkin is so large that the hypocotyls become thinner and adapted to the cucumber.
