【摘要】 本试验结果表明，对大棚春番茄进行膜下多孔管喷灌和微喷灌比沟灌有明显的节水、增产效果。节水率达４０％～６０％，增产幅度达７％～８％。膜下多孔管喷灌灌水后不泥泞，易于田间操作，是目前大棚春番茄栽培较理想的灌水方式。更多还原

【Abstract】 The results of the experiment showed that portable sprinking irrigation and porous pipe sprinkling irrigation under ─ plastic film had remarkable effect on water saving and product increase in comparision with furrow irrigation. The percentage was 40% ─ 60% and 7 % ～8 % for water saving and product increase, respectvely. The soil surface was not muddy after porous pipe sprinkling irrigation,and suitable for field operation. Hence, It is an ideal irrigation technique for tomato. in greenhouse in spring.更多还原
