短季亏缺灌溉条件下高密栽培对番茄产量和品质的影响

为充分利用北京地区3—5月的优质光热条件、稳定基质栽培番茄品质，通过改变传统栽培方法，采用在同一设施内，人为控制植株高度，只留2穗果和水分亏缺灌溉等栽培措施，研究不同栽培密度（每667 m²分别栽4 000、6 000、8 000株）对番茄产量及品质的影响，结果表明：每667 m²栽6 000株处理的果实可溶性固形物含量达到8.2%，667 m²产量为3 183.6 kg，均显著高于对照，且较对照667 m²新增纯收益2 484元，为适宜的高密栽培密度。

Effects of High Density on Tomato Yield and Quality under Short Season and Deficient Irrigation Cultivation Conditions

Abstract: In order to make full use of the high-quality light and heat conditions in Beijing from March to May, and maintain the quality of tomato cultivated in substrate, the effects of different planting densities (4 000, 6 000, 8 000 plants per 667 m2 ) on the yield and quality of tomato were studied by changing the traditional cultivation methods and adopting the cultivation measures such as artificial controlling the plant height, leaving only 2 ears of fruit and water deficient irrigation in the same facility. The results showed that the soluble solid content of fruit with treatment of 6 000 plants per 667 m2 was 8.2%, and the yield of fruit was 3 183.6 kg per 667 m2 , which were all significantly higher than that of the control, and the net income was 2 484 yuan per 667 m2 higher than that of the control, which was a suitable density of high density cultivation.
