Grafting seedling cultivation involves replacing the root system of cucumbers with resistant rootstocks,which can resist soil-borne diseases and pests.Improving the management of grafting cultivation and disease and pest control techniques has great significance for ensuring the safe production of cucumbers.This article summarized the cucumber grafting seedling cultivation and disease and pest control techniques.The grafting seedling cultivation technology mainly includes using pumpkin as the rootstock,sterilizing cucumber seeds with 50℃hot water,and then placing them in a 30℃environment for constant temperature germination.The grafting is carried out using the top insertion method of cucumbers.Ensure that the four leaflets of the grafted seedlings are arranged in a cross pattern;after grafting,timely shading,heating,and moisture retention treatments should be carried out.During this period,the axillary buds of the rootstock should be regularly removed.When the grafted seedlings grow to the 3-leaf 1-heart stage,they should be transplanted.The disease and pest control technology follows the agricultural protection policy of"prevention first,comprehensive control",mainly including agricultural control methods(precise regulation of temperature and humidity,selection of disease-resistant varieties,timely and scientific sowing,and reasonable crop rotation and intercropping,etc.),and physical control methods(hanging yellow boards,installing insect-killing lamps,setting up insect-proof nets,etc.),biological control(release of natural enemy insects,application of biological pesticides,etc.).This comprehensive control system is conducive to maintaining the ecological balance of farmland,promoting the sustainable development of agricultural ecosystems,achieving a synergistic improvement of economic and ecological benefits,and can provide a reference for green,efficient and sustainable production of cucumbers.
