不同播种期对吐鲁番秋季大田哈密瓜产量和品质的影响

摘要

为解决哈密瓜秋季生产中农户播种期不当造成的果实不成熟、经济效益低等问题,以‘西州密17号,哈密瓜为试材,在播种季设置6个播种期,以7月10日为对照,对不同播种期哈密瓜的物候期、生长发育、产量品质及经济效益等指标进行调查与分析.结果表明,在正常年份气候条件下,秋季大田哈密瓜适宜播种期以7月10-20日为宜,产量高,品质好,每667 m2纯收入为2 000～3 000元,产投比在1.8～2.2之间.%In order to solve the problem of unripe harvest and low output value of hami melon caused by autumn sowing time,the hami melon variety‘Xizhoumi No.17’ was used as material,6 sowing time was set,and the local normal sowing time July 10 was used as control.The phenophase,growth and development,yield,quality,output value and other indicators of these hami melons were investigated.The results showed that in normal climate conditions,the optimal sowing time was from July 10to July 20,when the hami melons should be with high yield and good quality,with net income in 2 000-3 000 yuan per 667 m2 and input-output ratio between 1.8 to 2.2.
