日光温室膜下滴灌水肥耦合技术对番茄生长发育的影响

Effects of water and fertilizer coupling on tomato growth and development under drip fertilization in solar-greenhouse

采用二因素二次通用旋转组合设计方法,在日光温室膜下滴灌条件下研究了水肥耦合技术对番茄生长发育的影响,结果表明:灌水和施肥对番茄各项生长发育指标的影响均十分显著,有利于番茄生长发育的最佳水肥耦合方案为灌水量2 722.5～2 836.95 m3/hm2、施肥量265.5～294.45 kg/hm2。

Under the condition of solar greenhouses drip irrigation, this test is studied effects of Water-Fertilizer coupling techniques on growth and development of tomato by two of factors in common used to rotate association design way： The results show that various growth and development indices of tomato are significantly affected by different treatments of water and fertilizer coupling, and that the optimal scheme of water-fertilizer coupling is irrigation quantity ranging between 2 722.5- 2 836.95 m^3/hm^2 and fertilization amount ranging between 265.5-294.45 kg/hm^2.
