【摘要】 为探索现代化温室中番茄采收期生长发育变化规律,以北京小汤山现代化日光温室为试验点,番茄品种‘普罗旺斯’为供试材料,对温室环境条件数据进行采集,并结合采收期的番茄植株和果实性状进行测定分析。结果表明:温室日平均温度较室外变化小,3—5月在20℃左右,6月为25℃左右,日平均相对湿度在70%左右,而辐射量变化较大,多数在150~270μmol/(m2·s)。番茄株高每周平均增长量从采收中期到拉秧逐渐减少,坐花坐果节位数每周平均的增长量也有所下降,果实坐果后经过8周能成熟采收,果实横纵径增长量下降明显,每周采收的果实单果重先增加再有所降低,最大平均单果重是125.2 g,而每周产量逐渐增加达到峰值每周0.74 kg/m2后大幅度下降。南向株高增量和坐花坐果节位增长量均略大于北向。更多还原

【Abstract】 For the purpose of exploring the growth and development of tomatoe during fruit harvest ingreenhouse, the experimental data of the greenhouse environmental conditions were collected, and the fruittraits in the harvest period were measured. The test used‘Provence’as material and the experimental site wasthe greenhouse of Xiaotangshan in the Beijing. The results showed that: the daily average greenhouse insidetemperature was about 20℃ between March and May, and about 25℃ in June, and the change range of it wassmaller than that of outside. The daily average relative humidity of greenhouse was about 70%, while thechange of radiation was larger, mostly in the 150-270 μmol/(m2· s). The mean growth of tomatoe plant heightper week was decreasing from the mid of harvest to uprooting plants. The mean growth of flower and fruitsetting position per week was also decreasing. After fruit setting, it took eight weeks for the fruit to become ripeand to be harvested. The mean growth of fruit transverse and longitudinal diameter per week decreasedsignificantly. The weekly harvest fruit weight decreased first and then increased, and the maximum averageweight per fruit was 125.2 g. The weekly production gradually increased to reach a peak of 0.74 kg/(m2·week)and then significantly declined. The mean growth of plant height and flower and fruit setting position per week in the south were slightly larger than that in the north.更多还原
