Abstract:
      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〉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.
