Baoyin He

Abstract

In view of the sunlight greenhouse tomato use drip irrigation under membrane ,the paper choose the quantity,the cycle and the number of times of rrigation as for the experimental factors to carry ou the experiment of irrigation schedule by complete combination of drip irrigation. The whole growingseason of spring tomato continues 130 ～ 135 days in greenhouse,the suitable drip irrigation times is 29, irrigation interval is equally 4 ～ 5 days,the main irrigation quota is 210 m3 /hm2,the suitable irrigation norm is 6150 m3 /hm2,the tomoto output is 15. 3 × 104 ～ 16. 05 × 104 kg/hm2.
