| 中文摘要: |
| 在日光温室膜下滴灌条件下，采用二因素二次通用旋转组合设计方法，以番茄为试验材料，研究了日光温室膜下滴灌水肥耦合技术对番茄生长发育的影响。结果表明：灌水定额、施肥定额二因素与番茄生长发育之间存在极显著的回归关系；有利于华北地区日光温室番茄生长发育的最佳水肥耦合方案为：灌水量2 722.5～2 836.9 m3·hm-2，施肥量265.5～294.4 kg·hm-2。 |
| 英文摘要: |
| Under the condition of solar greenhouses drip irrigation, this test is conducted to study effects of water-fertilizer coupling techniques on growth and development of tomato under mulch drip fertilization in solar-greenhouse. The results show that regression analysis is reliable (F回〉F0.01（5，7）=6.1088), and that a very significant regression relationship is found between irrigation ration and fertilizer ration. Therefore, it is proposed that the optimal scheme of water-fertilizer coupling is irrigation quantity ranging between 2 722.5～2 836.9 m3/hm-2 and fertilization amount ranging between 265.5～294.4 kg·hm-2 in North China, which may be applied to commercial tomato production. |
