泥炭复合基质对不同作物育苗效果的研究

用不同泥炭含量的土壤-泥炭复合基质进行玉米、菜豆、蓖麻种子育苗试验,结果表明,育苗基质中泥炭不同含量对作物种子萌发出苗和幼苗生长均有显著影响,且不同作物对基质泥炭比例有不同要求.对玉米、菜豆和蓖麻种子出苗的适宜基质泥炭含量分别为15%、10%和20%,而对其幼苗生长的适宜基质泥炭含量分别是20%、15%和25%.

Study on the Effect of Compound Peat Substrate to Raise Seedling for Different Crops

The raise seedling test using soil-peat compound substrates with peat different contents for maizeand frijoleand castor-oil plantseeds was carried out. The results showed that the seeds germination and emergenceand seedlings growth were influenced obviously by different peat contents in the substrates. And different crops needed different peat proportion. The suitable peat content in the substrates for producing seedling of maize and frijole and castor-oil plant seeds was 15%, 10% and 20%, and the suitable peat content in the substrates for seedlings growth was 15%, 10% and 20% respectively.
