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

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 m3/hm2 and fertilization amount ranging between 265.5~294.45 kg/hm2.
