To　improve　the　construction　methods　of　Chinese　solar　greenhouse　wall　to　enhance　the　heat　storage,　we　proposed　a　three-layer　wall　with　phase-change　materials,　namely,　an　inner　wall　layer　built　with　the　phase-change　materials,　an　outer　insulating　layer　and　a　load-bearing　wall　layer　built　with　heavyweight　materials　between　the　two.　Based　on　the　field　experiment　and　the　proposed　valuation　indexes　of　the　three-layer　wall,　the　dynamic　heat　storage　characteristics　of　the　wall　have　been　analysed　and　discussed.　The　experiment　and　simulation　results　showed　that　the　three-layer　wall　can　enhance　the　heat　storage　and　thermal　insulation　properties　of　greenhouse　wall,　increase　the　utilisation　rate　of　solar　energy,　improve　indoor　thermal　environment　and　increase　crop　yield　and　quality.　Therefore,　these　results　validated　the　suitability　and　correctness　of　the　construction　methods　of　the　three-layer　wall.
