日光温室基质栽培对‘红颜’草莓品种生长发育的影响

研究了追施有机肥的基质栽培对日光温室‘红颜’草莓生长发育的影响。结果表明,基质栽培地温的日变化趋势与对照基本一致,10 cm、15 cm日平均地温与对照一致,而5 cm、20 cm处存在差异;基质栽培植株生长势比对照稍弱,主要表现在叶片数减少、叶片纵横径变小;基质栽培植株显蕾期、盛花期比对照晚3~5d,但果实始熟期和成熟期仅比对照晚1 d;基质栽培产量和果实品质与对照差异不显著。基质栽培比较接近土壤栽培,可以用于解决设施栽培中草莓的重茬问题。

Effects of Substrate Culture on Growth of 'Benihoppe' Strawberry in Green House

In this experiment,effects of substrate culture applying organic fertilizer in green house on growth of 'Benihoppe' cultivar were studied.Experiment results showed that the diurnal changing trends of ground temperature in trialed substrate were similar to those of control soil.The ground temperatures of 10cm and 15cm substrate were similar to those of control soil,while ground temperatures of 5cm and 20cm were different.Substrate cultured plants grew weaker than control plants and there were less and smaller leaves on substrate cultured plants.Bud-appearing phase,full flowering phase of substrate cultured plants were 3~5 d later than control plants,but initial maturation phase and maturation phase were only 1d later.There were no significant differences in yield and quality between substrate cultured and control plants.Substrate-planting was similar to soil-planting and could be used to prevent the problems of replanting in strawberry production.
