摘　　要：大棚连续种植黄瓜,容易出现品质下降、产量下降等现象,而部分种植者盲目采用增加农药化肥用量来应对,结果导致土壤酸化、板结、盐渍化等连作问题。甲壳素在农业上具有农药、肥料双重功能,可以作为杀菌剂、植物生长调节剂使用。针对大棚连作黄瓜品质降低、产量下降问题,本研究在温室大棚连作黄瓜品种935的生产中,开展了甲壳素灌根试验。结果表明,甲克素灌根处理比对照植株株高增加23.96%,产量增加30.22%,可溶性固形物含量增加0.3%。由此可见,甲壳素可以改善黄瓜品质,提高产量,防控温室大棚连作障碍。Continuous cropping of cucumber in greenhouse is prone to quality and yield decline. Some melon farmers blindly increase input, such as water, fertilize, pesticides, to cope with these problems. As a result, the occurrence of soil acidification, consolidation, salinization and continuous cropping obstacles is accelerated. Chitin can be used as bactericide and plant growth regulator because of its dual functions of medicine and fertilizer in agriculture. In view of the problem of continuous quality and yield reduction of cucumber in greenhouse, this study carried out the root-testing of chitin in the production of cucumber ＂935＂ in greenhouse. The results showed that the treatment was higher than that of control plant. The increase was 23.96%; the yield increased by 30.22%; the content of soluble solids increased by 0.3%. It can be seen that chitin not only improves the quality of cucumber, but also improves the yield, and has the effect of preventing and controlling greenhouse cucumber greenhouses.
