不同灌水量对秸秆生物反应堆条件下番茄生长及产量的影响

为进一步完善秸秆生物反应堆技术的可操作性和实用性,通过在秋冬茬番茄上应用膜下滴灌的行下式玉米秸秆生物反应堆技术,分析不同灌水量对番茄生长指标及产量的影响。试验结果表明:常规灌水量下秸秆腐熟程度最好;667 m~2灌水量下浮30%较常规处理节水18.71 m~3、增产1 008.84 kg,节水增产效果明显。

Effects of Different Irrigation Amount on Growth and Yield of Tomato Grown on Straw Bioreator

Agricultural Technology Extension and Service Center of Shapotou District, Zhongwei 755000, ChinaAbstract: In order to improve the operability and practicability of straw bioreactor technology, thegrowth index and yield of tomato were analyzed under different irrigation amount through the applicationof corn straw bioreactor technology of drip irrigation under membrane in the autumn-winter. The resultsshowed that maturity extent of straw was the best under conventional irrigation amount. Comparedwith the conventional treatment, the amount of irrigation per 667 m2 decreased by 30% saved water18.71 m3 and increased yield by 1 008.84 kg, which the water-saving and yield-increasing effects wasobvious.
