稻谷壳灰.锯木屑以及两者不同的配比混合物作为塑料大棚无土栽培番茄的基质,其中以两者体积为2:1的混合基质表现最好,三年两季产量都比对照(园土)和锯木屑基质增产39～48％,番茄的植株高度、花序数、果穗数、座果数以及伤流强度都高于对照;全株和根系的干物重分别比对照增加59％和78％;绿叶数和叶片叶绿素含量及根部最长根长度、平均根长也超过对照并持续到拔株期。此外,对混合基质无土栽培增产的原因进行了讨论。
Rice hull ash, sawdust and the mixture of the two as a substrate for soilless cultivation of plastic greenhouse greenhouse, in which the volume ratio of 2: 1 mixed matrix best performance, three-year yield of two seasons than the control (Park Soil and sawdust matrix increased by 39-48%. The plant height, the number of inflorescences, the number of ears, the fruit number and the wounding intensity of tomato were higher than those of the control. The dry weight of whole plant and root increased by 59% and 78% respectively %; The number of green leaves and chlorophyll content of leaves and the longest root length of root, the average root length also exceeded the control and continued until the plantlet. In addition, the reasons for the increase of soilless culture of mixed substrates were discussed.
