| 摘 要： | 在覆膜滴灌条件下,对高密度栽培加工番茄的耗水规律及产量进行研究。结果表明:高密度栽培加工番茄最大耗水时段在6月26日—8月7日,日均耗水量6.15 mm,其中7月上旬的日均耗水量为6.8 mm,7月中旬的日均耗水量最大,为7.3 mm,7月下旬的日均耗水量为5.1 mm。日平均气温在20℃~25℃时,田间蒸散量最大,均值达205.19 mm,天数为56 d,日均耗水量3.66 mm,以每次灌水40mm,应灌水次数为5~6次,间隔9~10 d。同时,大田不同灌溉量试验表明,随着灌溉量的增加,加工番茄的产量逐步提高。利用蒸渗计计算理论灌量,通过回归计算,可得最大理论产量约188.69 t/hm2。

| Abstract: | Under the condition of high-density planting and mulched drip irrigation,the rules of water consumption and yield of tomato are studied.The results show that the maximums water consumption period is from June 26 to August 7,CWC is 6.8 mm in early July,CWC is 7.3 mm in mid July,CWC is 5.1 mm in late July,and the everyday capacity of water consumption(CWC) is 6.15 mm.When the average daily temperature is in 20℃～25℃,the maximum evapotranspiration is 205.19mm,the duration is 56 days,the CWC is 3.66 mm,and the total CWC is 205.19 mm.During this period of time,the frequency of drip irrigation should be 5～6 times,with a quantity of 40 mm in each time of irrigation,and the interval bwtween two times of irrigation should be 9～10 days.The field experiment shows that tomato yield increases gradually along with the increase of irrigation and,calculated by means of the regression equation,the maximum theoretical yield may reach 188.69 t/hm2. |
