ModPlacedFeatures中：

public static final RegistryKey<PlacedFeature> CHESTNUT_PLACED_KEY = registerKey("chestnut_placed");


        register(context, CHESTNUT_PLACED_KEY, configuredFeatureRegistryEntryLookup.getOrThrow(ModConfiguredFeatures.CHESTNUT_KEY),
                VegetationPlacedFeatures.treeModifiersWithWouldSurvive(PlacedFeatures.createCountExtraModifier(2, 0.1f, 2),
                        ModBlocks.CHESTNUT_SAPLING));

ModTreeGeneration：

public class ModTreeGeneration {
    public static void generateTrees() {
        BiomeModifications.addFeature(BiomeSelectors.includeByKey(BiomeKeys.PLAINS, BiomeKeys.FOREST),
                GenerationStep.Feature.VEGETAL_DECORATION, ModPlacedFeatures.CHESTNUT_PLACED_KEY);
    }
}

ModWorldGeneration：

ModTreeGeneration.generateTrees();
