为了分析不同灌溉方式的节水效果和对植物生长发育的影响,通过对大棚西红柿进行沟灌、滴灌和地下灌溉3种灌溉方式的试验,分析不同灌溉方式、灌水量、注射深度对大棚西红柿茎粗、根系活力、产量和西红柿品质的影响。试验结果表明:地下灌溉的节水效果显著高于沟灌和滴灌;而在地下灌溉试验的比较中,当每次注射水量为0.75 L时,西红柿的总产量和根系活力最高;试验同时表明距离地表约30 cm的注射深度时,西红柿的根系活力强,有利于西红柿生长。
In order to analyze the effect of different irrigation methods on water saving and the effect on plant growth and development, the effects of different irrigation methods, irrigation amount and depth of injection on stem diameter of tomato in greenhouse were analyzed through three kinds of irrigation methods: furrow irrigation, drip irrigation and underground irrigation. , Root vigor, yield and the quality of tomatoes. The results showed that the underground water saving effect was significantly higher than that of furrow irrigation and drip irrigation. In the comparison of underground irrigation experiment, the total yield and root activity of tomato were the highest when the water injection volume was 0.75 L per litter. At the same time, When injected at a depth of about 30 cm, the tomato root vigor is strong and conducive to the growth of tomatoes.
